Abstract

The invented technology adopts waste paper, discarded wood, waste cloth as raw materials, the raw materials are selected, then added in water and alkali with the quantity according to the total wt. of raw material, loaded in the rotary spherical digester and digested, screened, the dregs dischorged, and the selected slurry is obtained and put into the poteher to potch then transferred to the disc attrition mill for pressing: add aluminium sulphate, tale powderand rosin gum, and after beated into pulp, it passes through paper-making machine to obtain the product. The invention reduces the amount of alkali used, fully utilizes waste paper, discarded wood, waste colth, and reduces the environmental pollution, lowers the prodn. cost. This product possesses good paper-forming property, good folding strength, good toughness etc.

Description

A kind of technology of producing explosive paper roll

The present invention relates to a kind of technology of producing explosive paper roll.

Explosive paper roll is mainly used in the packaging material of Chemical Manufacture explosive, requires it to have higher physical strength and moderate suction wax performance for this packaging material.At present, existing explosive paper roll production technology generally all adopts a large amount of wood pulps or linen-cotton to make raw material, and when producing, also to add heavy alkali (its add alkali number be generally the raw material total amount 12%～14%), this is the cost height not only, but also environment has been caused great pollution, in addition, if under existing processes, paid attention to the factor of physical strength, but be difficult to improve the suction wax performance of coil paper, thereby the explosive paper roll that the employing prior art is produced in use, generally all exists shortcomings such as breakage rate is higher, the packing resistance is bigger.

The objective of the invention is: provide a kind of manufacturing explosive paper roll technology that adopts waste material and little alkali, to reach twice laid, to reduce the purpose of polluting, reducing production costs, improve the quality of products.

The present invention is achieved in that its employing waste paper, scoot, useless rag is a raw material, earlier carry out various raw materials selected, and get rid of rigid foreign material and nylon, foreign material such as plastics, again with the raw material pulverizing after selected, press the alkali that the raw material gross weight adds 2～3 times of water and 1.5%～3%, with boiling in its rotary spherical digester of all packing into 1～7 hour, pressure in the rotary spherical digester is 0～4.2Kg, temperature is 150 ℃～160 ℃, the raw material of boiling is screened deslagging get selected slurry, selected slurry is put into the rinsing bath rinsing, slurry after the rinsing adds aluminum sulfate 4%～8% by its weight after the disk mill is exerted pressure decomposition, talcum powder 3%～6%, gum rosin 0.3%～0.5% gets pulping after making beating, pulping is sent into the paper machine through typing, promptly get explosive paper roll after the roll-in; The ratio that each raw material accounts for whole raw material gross weights is: waste paper 65%, scoot 15%, useless rag 20%; When useless rag amount does not reach 20%, can adopt wood pulp to replenish; Waste paper comprises waste and old books and newspapers, waste paper bag, cardboard, seed of Jobs tears bar, bajiao banana taro bar.

Owing to adopt technique scheme, the present invention compared with prior art, reduced the consumption of alkali widely, refuses such as discarded waste paper, scoot, useless rag have been utilized fully, this not only alkali lacked environmental pollution, but also reduced production cost, and characteristics such as the explosive paper roll of being produced has, and paper properties is good, physical strength is high, folding, anti-broken, good toughness, suction wax are moderate, these coil papers have packing explosive reel inner wall smooth, cover reel fashion cover, resistance is little, breakage rate is little advantages such as (its breakage rate generally can not surpass 2%) in use.

Embodiments of the invention: (waste paper can be waste and old books and newspapers with waste paper, the waste paper bag, cardboard, the seed of Jobs tears bar, bajiao banana taro bar etc.), scoot, useless rag is a raw material, earlier carry out various raw materials selected, get rid of rigid foreign material and nylon, foreign material such as plastics, get 910 kilograms in waste paper, 210 kilograms of scoots, 280 kilograms (the rag amount inadequately constantly if give up for useless rag, 140 kilograms of desirable useless rags, 140 kilograms of wood pulps), with each raw material pulverizing, the alkali that adds 3g20 kg of water and 28 kilograms, with the boiling 5.4 hours again after 20 minutes of first dry running in its rotary spherical digester of all packing into, during boiling with the Pressure control in the rotary spherical digester about 3Kg, temperature is between 150 ℃～160 ℃, the raw material of boiling is screened deslagging get selected slurry, selected slurry is put into the rinsing bath rinsing see that up to washing clear water ends, again the slurry after the rinsing is exerted pressure with double plate disk mill and decompose the back by its weight adding aluminum sulfate 6%, talcum powder 5%, gum rosin 0.5%, after making beating, get pulping again, pulping is sent into the paper machine through typing, promptly get explosive paper roll after the roll-in.

Claims

1, a kind of technology of producing explosive paper roll, it is characterized in that: it adopts waste paper, scoot, useless rag is a raw material, earlier carry out various raw materials selected, and get rid of rigid foreign material and nylon, foreign material such as plastics, again with the raw material pulverizing after selected, press the alkali that the raw material gross weight adds 2～3 times of water and 1.5%～3%, with boiling in its rotary spherical digester of all packing into 1～7 hour, pressure in the rotary spherical digester is 0～4.2Kg, temperature is 150 ℃～160 ℃, the raw material of boiling is screened deslagging get selected slurry, selected slurry is put into the rinsing bath rinsing, slurry after the rinsing adds aluminum sulfate 4%～8% by its weight after the disk mill is exerted pressure decomposition, talcum powder 3%～6%, gum rosin 0.3%～0.5% gets pulping after making beating, pulping is sent into the paper machine through typing, promptly get explosive paper roll after the roll-in.

2, a kind of technology of producing explosive paper roll according to claim 1, it is characterized in that: the ratio that each raw material accounts for whole raw material gross weights is: waste paper 65%, scoot 15%, useless rag 20%; When useless rag amount this less than 20% the time, can adopt wood pulp to replenish.

3, a kind of technology of producing explosive paper roll according to claim 1 is characterized in that: waste paper comprises waste and old books and newspapers, waste paper bag, cardboard, seed of Jobs tears bar, bajiao banana taro bar.
