Abstract
The invention provides a method for increasing the recovery rate of waste paper pulp and improving the recovery efficiency of the waste paper pulp by means of an auxiliary. The method comprises the steps that 1, raw materials are prepared according to the weight ratio; 2, wollastonite powder and zinc carbonate are mixed and then ground till the particle size ranges from 20 micrometers to 30 micrometers, and a mixed material is obtained for use; 3, water is frozen into ice blocks, the ice blocks are crushed into crushed ice blocks, the crushed ice blocks are molten at normal temperature till the weight ratio of ice to water is 2:3, the mixed material, nano-silicon dioxide, urea, chitosan and ethanol are added, the materials are stirred to be uniform, and then the auxiliary which can be used is obtained; 4, the auxiliary is added into a hydrapulper before the ice blocks are completely molten. According to the method, the recovery rate of the waste paper pulp is increased and the recovery efficiency of the waste paper pulp is improved by means of the auxiliary, and the auxiliary takes ice water and ethanol as solvents, can be quickly and uniformly dispersed into the paper pulp, has the effect of accelerating paper pulp disintegrating and improves the tearing effect of water flow on recovered paper and the pulping efficiency; more paper pulp fibers can be dissolved out, and the effective utilization rate of the recovered paper and the recovery value are increased.
Description
Technical field
The present invention relates to waste paper recovery technology field, more particularly, to one kind are improved the old paper stock rate of recovery using auxiliary agent and are returned
The method of rate of producing effects.
Background technology
With the lifting of people's environmental consciousness, in today of paper industry fast development, particularly industrial packaging paper material
Structure has progressively been adjusted to based on wastepaper as raw material, and waste paper, in pulping process, in order to improve the utilization rate of waste paper, needs to the greatest extent may be used
The recycling waste paper fibre of energy.During waste paper pulp-making, final to whether being thoroughly directly connected to of old paper stock dissolution
The rate of recovery of paper pulp fiber.
Content of the invention
It is an object of the invention to provide a kind of method that utilization auxiliary agent improves the old paper stock rate of recovery and organic efficiency, mesh
Be improve the dissolution ratio of old paper stock fiber and dissolution efficiency.
The technical problem to be solved employs the following technical solutions to realize：
A kind of method of utilization auxiliary agent raising old paper stock rate of recovery and organic efficiency is it is characterised in that step is as follows：
(1) by weight preparation raw material, including：
0.3 part of urea, 0.5 part of shitosan, 2 parts of wollastonite in powder, 0.1 part of zinc carbonate, 15 parts of nano silicon, ethanol 50
Part, 5000 parts of water；
(2) first wollastonite in powder, zinc carbonate are mixed, being ground to granularity is 20-30 micron, obtains mixed material stand-by；
(3) water-cooled is frozen into ice cube, is then broken into rubble ice, it is 2 that normal temperature dissolves to ice water weight ratio：3, it is subsequently adding
Mixed material, nano silicon, urea, shitosan, ethanol, stir, that is, obtain the auxiliary agent that can use；
(4) before ice cube dissolves completely, auxiliary agent is added in hydrabrusher, auxiliary agent accounts for weight of material in hydrabrusher
20%.
Step (3) can also be changed to：Nano silicon is added to the water, stirring makes nano silicon be dispersed in
In water, quick-frozen one-tenth ice cube, so that nano silicon is dispersed in ice cube, then ice is broken into rubble ice, normal temperature dissolves
It is 2 to ice water weight ratio：3, it is subsequently adding mixed material, urea, shitosan, ethanol, stirs, that is, obtain using
Auxiliary agent.
The diameter of described rubble ice or seamed edge size are in 1-3.5cm.
Described auxiliary agent uses in the presence of having solid water, it is possible to increase paper pulp rate of dissolution, reduces waterpower paper pulp institute
The time needing.
The invention has the beneficial effects as follows：
The present invention utilizes auxiliary agent to improve the rate of recovery of old paper stock and organic efficiency, auxiliary agent with frozen water and ethanol as solvent,
And as urea, shitosan, wollastonite in powder, zinc carbonate, nano silicon carrier, can rapidly and uniformly be distributed to paper pulp
In, play the role of to accelerate paper pulp to burst solution, increase the effect of tearing to reclaim paper for the current, improve pulping efficiency；Can dissolve more
Many paper pulp fibers, improve the effective rate of utilization of reclaim paper, improve recovery value.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention realizes are easy to understand, tie below
Close specific embodiment, the present invention is expanded on further, but following embodiment is only the preferred embodiments of the present invention, and not all.
Based on the embodiment in embodiment, those skilled in the art are obtained other real on the premise of not making creative work
Apply example, broadly fall into protection scope of the present invention.
With reference to specific embodiment, the present invention is described.
A kind of auxiliary agent for improving the old paper stock rate of recovery and organic efficiency, is made up of the raw material of following weight portion：
0.3 part of urea, 0.5 part of shitosan, 2 parts of wollastonite in powder, 0.1 part of zinc carbonate, 15 parts of nano silicon, ethanol 50
Part, 5000 parts of water.
Improve the old paper stock rate of recovery using auxiliary agent and the method for organic efficiency is：
First wollastonite in powder, zinc carbonate are mixed, being ground to granularity is 20-30 micron, obtains mixed material stand-by；
Nano silicon is added to the water, stirring makes nano silicon be dispersed in water, quick-frozen one-tenth ice cube makes
Nano silicon is dispersed in ice cube, then ice is broken into rubble ice, and it is 2 that normal temperature dissolves to ice water weight ratio：3,
It is subsequently adding mixed material, urea, shitosan, ethanol, stirs, that is, obtain the auxiliary agent that can use；
