Raw materials for the production of paper containers and cardboard. Dictations simple and complex

The main raw material is wood pulp. It is obtained by chemical processing of coniferous or hardwood trees. There are 2 methods: sulfate and sulfite. The first method uses wood of any species. Wood crushed into chips is processed by cooking in sulfate liquor containing 9-10% NaOH at a temperature of 165-170 ° C and a pressure of 0.6-0.8 MPa. This is the most common method. Sulfite is used mainly for coniferous species. The chips are treated with sulfite liquor, which contains sulfur and sulfuric acid in the form of sodium, magnesium, calcium and ammonium hydrosulfites, at 130-135 ° C and a pressure of 0.5-0.8 MPa. In both cases, cooking lasts at least 5-7 hours. After this, mechanical impurities are removed from the cellulose pulp and, if necessary, subjected to additional chemical treatment - bleaching. Bleaching is carried out with chlorine-containing oxidizing agents (chlorine or its acid anhydrites) or compounds containing active oxygen (peroxides). The latter processing method is more environmentally friendly. This operation is important from a quality point of view, since bleached pulp is used to produce high-quality paper and cardboard.

During the production of cellulose, wood is removed most of lignin, which increases paper stiffness but reduces paper quality, and other substances. The yield of cellulose after processing is 50-60%. Sulfate cellulose serves as a semi-finished product in the production of packaging types of paper and cardboard, and its content largely determines the strength properties of the container. It is more expensive than sulfite pulp and darker than it (unbleached types). Sulfated cellulose - main

semi-finished product for the production of sack and wrapping paper, grade A (has high strength properties).

To reduce the cost, wood pulp is added to the composition of the pulp - a product of wood abrasion, and thermomechanical wood pulp obtained by grinding steamed wood chips. Its addition makes the paper plump, stiff, reduces strength properties, durability, and fracture rate. Wood pulp is used in the manufacture of packs and cardboard boxes. Also used as additives are semi-cellulose (crushed product of incomplete processing of wood), natural cotton fibers - cotton, flax, hemp and jute.

In production, waste paper is used to reduce the cost. It is distinguished by the multiplicity of fibers used. Primary or return is paper-making waste, the cleanest. Second-generation waste paper that has undergone printing is waste from the printing industry. Waste paper extracted from solid household waste or recycled paper - the least clean. It requires special sanitary treatment. Layer of paper or cardboard in contact with food products, must not contain waste paper.

Raw materials and semi-finished products for cardboard production depend on the type of cardboard and its purpose. For the production of flat cardboard, primary raw materials are used - bleached or unbleached cellulose. To reduce the cost of cardboard, refined waste paper and wood pulp are added to the components.

In the production of corrugated cardboard, sulfate or sulfite unbleached cellulose, wood pulp, cellulose sorting waste, paper pulp from sorted waste paper, unsorted waste paper.

Who doesn't know what paper is? We write dozens of pages every day! Statements, reports, powers of attorney, deeds, business and private correspondence... Can all this exist without paper? And how much of it goes into publishing newspapers, magazines, and advertisements! Add to this the huge circulation of books - textbooks, works of classics, modern writers, translated literature, among which detective stories are very popular.

Wherever do you come across such an ordinary thing as paper magic! Without her, our life is now completely unthinkable. Is it possible to imagine the literary process, teaching, book publishing without paper? But there was a time when people managed without it.

Clay and waxed plates, birch bark and silk strips, and carefully leveled boards were once used for writing. But they were inconvenient and unsuitable for long-term storage. Imagine a book depository in which manuscripts of this kind are collected. How much space will be required to accommodate them! It is not difficult to guess that this situation could not continue in the conditions of cultural progress of mankind.

How did paper appear? Who invented it?

The paper was created by an unknown master in China, traditionally isolated from the rest of the world. The paper was initially produced in strict secrecy. Bamboo, soaked in water for a long time, was boiled until it turned into a loose mass. The composition, diluted with water and well mixed, was then bleached in the sun. Dried and pressed, this paper was not High Quality.

The Chinese tried to maintain a monopoly on the secrets of the paper industry, but nevertheless the secret became clear. They say that these secrets were revealed by Chinese prisoners of war. These legends, however, remained unconfirmed. Material from the site

On modern factory High-quality paper is obtained from deciduous and coniferous wood. Crushed, soaked special composition, tree trunks boiled at a special temperature must be turned into a flowing mass. Then the knots that have not yet been fully cooked are separated from it, and it is almost ready. The structure of paper is special: it consists of fibers, densely intertwined and closely interlocked.

In our age of scientific and technological progress, materials more convenient than ordinary paper have already been found. Almost no different from her in appearance, not burning in fire, not decomposing, not absorbing moisture, the new “paper” becomes a true miracle. Even buried in the ground for a long time, it remains the same and does not lose its strength.

Recycling of waste paper reduces the need for deforestation for production various types paper and cardboard.

After all, paper and cardboard are a compressed and dried mass consisting of wood pulp(a water-insoluble substance, the main component of the cell walls of land plants) and glue that connects the fibers into one.

When recycling waste paper, do the following:

remove glue, connecting cellulose fibers into one whole;
cleanse from pollution;
turn into pure mass, suitable for the production of paper and cardboard or any other application (ennobled).

old newspapers,
magazines,
paper bags,
cardboard boxes and so on.

They are first converted into pulp and then into finished products.

Recycling of waste paper into paper, cardboard and other products is carried out in several stages.

The number and purpose of these stages depends on:

type of waste paper;
further use of the purified mass.

Therefore, we can conditionally divide processing into two stages.

First stage

The first stage includes the following actions:

sorting;
grinding;
primary dissolution;
purification from impurities.

paper break into fragments 1–5 cm in size, suitable for further processing.

For this operation use mills and crushers, and not necessarily intended for waste paper. You can also use crushers for plastic or wood chips.

Attempt to carry out initial dissolution of waste paper mass without crushing feedstock will lead to excessive consumption of electricity, because large fragments are more difficult to turn into an aqueous solution.

This process is often excluded from the technological chain when processing small volumes of waste paper due to high expenses for the purchase of a mill. In this case, use more powerful pulpers with a vertically mounted rotor.

The stage described above makes it possible to obtain from waste paper a substance suitable for the production cardboard and egg packaging.

Second phase

To obtain raw materials for paper production, a second stage is required, which includes:

secondary dissolution;
thin cleaning;
additional processing.

Secondary dissolution and fine cleaning are carried out in the same way, regardless of the feedstock and the final product.

The differences in these operations begin during additional processing, when not only mechanical action is applied, but also chemical reagents.

The composition of the reagents and the processing technology depend on both the brand of waste paper and the purpose of the pulp.

After completing the second stage, a purified aqueous solution is obtained, from which various grades of paper are made.

Sometimes this aqueous solution is mixed with unrecycled cellulose. During this operation, raw materials suitable for manufacturing are made from any waste paper. quality paper.

Waste paper sorting

Recycling begins with sorting, during which waste paper is divided into conventional groups quality. Thanks to this division, only waste paper that corresponds to technological chain specific device or plant.

All paper differs in:

color;
length of cellulose fibers;
degree of contamination;
humidity.

Each grade of paper requires its own pulping and cleaning technology.

Operates on the territory of Russia GOST 10700-97, according to which all waste paper is divided into three main groups:

Waste production white uncoated and unbleached sulfate paper, including non-waterproof paper bags.
Printing products without binding (except for newspapers), as well as regular and corrugated cardboard and black or brown paper.
Newspapers, paper and cardboard impregnated, colored paper (except black and brown), as well as paper and cardboard casting.

More accurate division of waste paper into stamps within groups, you can read GOST 10700-97 yourself by following this link http://docs.cntd.ru/document/1200030476.

Waste paper sorted manually, however, attempts do not stop automation this process, for which they are developing new modern equipment And software. To mechanize this process, it is necessary to “teach” the computer to distinguish between groups and brands of paper by appearance, which is very difficult to do at the current level of development of microelectronics.

Primary defibration

The purpose of this operation is glue dissolution, connecting individual fibers into a coherent structure and release of fibers.

For this waste paper:

placed in pulpers;
poured water;
stir.

The pulper consists of:

stator;
rotor (drum or impeller);
baths;
electric motor.

Hydropulpers work on the principle of a washing machine - drum(on some models this role will be played by an impeller) creates a vortex that carries along water and waste paper. Pulpers differ in:

rotor location (there are vertical and horizontal);
productivity;
concentration of the finished solution.

Water fills the cellulose fibers, they swell, breaking the glue, and the paper turns into liquid waste paper(pulp) suitable for further processing.

Friction and shocks that occur when waste paper collides with the walls of the bath, improve dissolution material. During the initial dissolution, cellulose peels off from various films, which allows for further separate fibers from contaminants.

All this happens due to the fact that water destroys the adhesive bond between individual fibers, replacing it with water bridges, which have low strength and facilitate the movement of fibers relative to each other.

Cellulose fibers are composed of fibrils(long thin threads) forming lamellas(layers). During dissolution the following processes occur:

the connection between individual fibers is broken;
the fibers become shorter;
the connection between the lamellas is broken;
the slats become shorter;
Due to the destruction of the lamellas, the cellulose fibers become covered with a fringe of fibrils.

After filling the waste paper with water stir so that friction accelerates and makes processes occurring in water more efficient, leading to separation:

fibers;
glue;
various contaminants.

Swirl, created by a rotating drum, presses the soggy waste paper mass against the walls of the bath, providing the following effects:

stirring;
rubbing.

Thanks to this, it happens separation waste paper mass into factions, which makes it easier to clean. At this stage, waste paper is used to create pulp which is used for:

production low grade cardboard;
soft fillers(cheap analogue of foam chips);
egg packaging;
further purification and processing.

Cleaning from impurities

Some pulper models are equipped with different catchers, which are removed from the waste paper mass:

paper clips;
ropes;
films;
sand.

For better cleaning, install additional catchers, because they improve cleaning waste paper and reduce costs for electricity for post-treatment.

The lower part of the bath of any pulper is equipped with dirt collector, where large contaminants that have passed through the catchers during the initial dissolution process end up.

After the dirt collector and catcher, the suspension flows through pipes to vibrating sieve, which carries out additional cleaning.

Here are eliminated all major pollution and foreign objects, not removed in previous waste paper cleanings.

As additional element, which improves the cleaning of waste paper, is used overflow box.

The liquid suspension easily flows through it, heavy contaminants settle to the bottom, then they are removed.

The resulting product is used for:

receiving quality cardboard;
production roofing materials;
further processing.

Secondary defibration

Secondary dissolution occurs on the same principle as primary, but in devices called:

Turbo separators.
Fiberizers.
Enstippers.
Pulsation mills.

The operating principle of the first three devices is the same, because it is a pulper with a special rotor shape. The form depends on:

device performance;
bath volume;
suspension concentrations;
depth of dissolution of waste paper into fibers.

They are used for preparation low and medium suspensions quality. The fourth device (pulsation mill) differs from the others in that the rotor and stator are made in the form disks of complex shape.

Due to the shape of the rotor, small water hammer, which are called pulsations. The distance between the discs is 0.2–2 millimeters, which is comparable to the size of the fibers.

The rotor not only creates swirl, but also provides suction suspension, after which water hammer (pulsation) and friction finally destroy adhesive bonds between cellulose fibers. Therefore, a pulsation mill is used to prepare high quality suspensions.

Each of these devices is equipped with dirt traps, so at the same time as fiberization, the suspension is cleaned of dirt.

In the process of secondary dissolution it is necessary not only destroy ties between individual pieces of cellulose fibers, but also do not allow dirt to grind and foreign inclusions so that they can be screened out with special equipment.

For production low quality cardboard or cellulose casting in one unit they carry out:

primary defibration;
cleaning;
additional clearance.

However, the use separate devices more effective, therefore this approach is used for production quality material.

Fine cleaning

Fine cleaning is carried out different ways, complementing each other, because some one method does not provide the necessary cleanliness waste paper mass.

Typically, fine cleaning takes place in the following sequence:

using a sorting device;
using a thermal dispersion device.

Cleaning with

Further cleaning can be done using various additional equipment, which we will discuss in detail below.

Sorting device

The pulp purified at the previous stage is fed to a sorting device, which:

additionally cleanses from heavy and solid contaminants;
divides the mass according to the size of the fibers.

Sorting device– this is a vibrating sieve with small cells, so it is too fine fibers and dirt pass through the holes in mud trap.

Very short fibers are not suitable for paper production, so they are either disposed of in accordance with standards accepted in Russia, or sent for additional processing.

For example, they are mixed with the pulp obtained as a result of primary dissolution. From this mass they make low quality cardboard, egg packaging or various building materials. The pulp that has passed through the sorting device is used to make medium quality paper and cardboard.

Thermal dispersion device

The next stage of cleaning is processing for thermal dispersion device, which removes from the pulp:

petroleum derivatives;
fats;
resins;
various films.

Thermal dispersion devices separate the pulp into water-soluble And water-insoluble components using heat. Then all water-insoluble components are filtered and collected in garbage receptacle.

In the process of processing the pulp again grind similar to what happens in a pulper or pulse mill. Therefore, for paper production High Quality the resulting product is filtered using vibrating screens or similar devices to separate fibers that are too short.

After the fine cleaning stage, the waste paper mass (pulp) is suitable for:

paper making average quality;
further processing.

All contaminants collected during the dissolution or purification process are allowed for further processing at the appropriate enterprises or disposed of in accordance with the standards accepted in Russia.

Additional processing

Waste paper mass get rid of dyes And increase paper-forming properties properties of the material.

If necessary, into waste paper add wood pulp to improve the quality of the final product.

Wood cellulose fibers are very long, making it successful bind short fibers obtained from waste paper.

To decolorize and bleach waste paper, use:

mechanical impact;
heat;
chemical reagents, the composition of which depends on the color and brand of raw materials, as well as on the type of finished product.

For the manufacture of quality paper nessesary to use pulp with certain characteristics, which include:

size and structure of cellulose fibers;
amount of additional impurities;
color;
microbiological composition;
chemical composition.

The size and structure of the fibers affect paper strength And glue consumption. The longer the fibers and the more fringes they have from fibrous tissues, the higher paper-forming properties of pulp, that is, those stronger will be the paper obtained from them.

Fibers less than 0.2 millimeters long not suitable for paper production, however, the dense fringe of fibrils allows them to be used for casting or cardboard production.

If the entire pulp consists of short fibers, then it diluted with wood pulp, increasing paper-forming properties. If necessary, pulp bleach or attach desired color, cleanse from odors and bacteria. This gives the pulp necessary qualities and prepares it for the production of any goods.

Laminated cardboard recycling

Laminated cardboard— mass segment of paper waste. This is packaging Pure Pak and Tetra Pak, in which many types of products are sold - juices, milk, etc.

Comprehensive processing of laminated cardboard waste allows you to obtain the following:

high quality cellulose various varieties and colors;
secondary polyethylene;
polyaluminum.

Due to the technical difficulty of completely separating laminated board into its component parts Such processing is rarely done anywhere.

Recycling paper at home

Recycle paper waste You can do it at home. But without special equipment, if only improvised means, the only thing that can be done is homemade paper. This method will be useful for designers and hand-makers.

Making paper at home:

Unnecessary paper (not glossy or laminated) should be finely tear or cut.
Add paper pulp into the blender, add water and grind to a pulp state.
The resulting mass post onto a sieve or frame with gauze, level it and leave under pressure.

After drying out the paper is ready. Dense and rough, it can be useful for handmakers to create their masterpieces.

Equipment for recycling waste paper

Modern industry offers a large number of diverse technology for recycling waste paper, including:

individual installations for each operation;
combined installations for several operations (mini-plants);
factories, performing the entire technological chain.

Mini-mills are in demand in those places where the supply of waste paper does not exceed 3–5 tons per day, because in this case it makes no sense to invest in powerful, expensive equipment.

Individual installations for each stage are purchased when the average waste paper flow is expected – 10–50 tons per day, if stable supplies of waste paper occur in significantly larger volumes, then using a plant is preferable.

Below is table approximate prices for various equipment used for recycling waste paper, so that you can more clearly understand the scale of investment in this type of business.

What else is made from waste paper? Alternative processing methods

Except traditional processing into paper and cardboard from waste paper make the following materials:

organic insulation ( ecowool);
roofing materials;
insulating materials;
disposable pots for flowers;
packaging for eggs;
toilet paper;
paper napkins;
disposable dishes;
textile for clothes.

Primary stage processing, including the production and purification of pulp, for all these technologies is the same.

Attempts are being made dry destruction of bonds between cellulose fibers, but so far they are far from commercial application.

Decoration Materials from compressed cellulose fibers according to their characteristics similar popular fiberboard sheets, but cheaper their.

Ecowool made from waste paper, its characteristics are not much inferior to basalt and glass wool, harmless and again recyclable.

Very in demand shock-absorbing fillers pressed from cardboard, which are in no way inferior to foam chips, but much cheaper. Their production does not require complex equipment, and the machine for making such crumbs does not take up much space.

Industry prospects

Recycling of waste paper in various materials Very in demand, so the industry is constantly develops.

Declining forests and the reduced availability of unprocessed wood pulp are driving the industry's explosive growth. In addition, recycling waste paper allows save trees that would need to be cut down to make paper.

Despite the need for large investments, waste paper recycling is Very profitable business , because the raw materials are very cheap, and paper and cardboard are used demand. The low price allows you to effectively compete with paper made from wood, because there are no costs for cutting down forests, delivering logs, storing them and processing them into chips.

The profit of an enterprise is affected by access to the following resources:

cheap electricity;
cheap water;
cheap reset waste water;
inexpensive storage area garbage and waste.

Recycling waste paper into paper is very profitable business, which is constantly evolving. New technologies are emerging that improve the process and increase the number of waste paper recycling cycles. Appear new materials, for which it is required recycled cellulose.

The industry is developing successfully, covering large and small cities, because demand for paper products only increases, and the raw materials are very cheap.

After all, many people still throw newspapers and magazines into the bin, but they can get even a small amount for waste paper, but payment.

In the near future, new technologies will appear that will make it possible to seriously increase the number of cycles recycling waste paper, which will reduce the number of trees cut down and improve the environment.

Implementation in the near future separate collection garbage significantly will increase the volume waste paper and cardboard that can be recycled.

This will ensure increase in quantity supplied raw materials, which means it will increase the output of finished paper. The development of technology will increase the number of paper recycling cycles, because even very short fibers can be used, if you mix primary cellulose with them.

The video briefly and interestingly describes the process of recycling waste paper, as well as why it is so important for the environment:
