Abstract
The invention provides a recycled paper pulp dissolving aid. The recycled paper pulp dissolving aid is prepared from, by weight, 0.3 part of urea, 0.5 part of chitosan, 2 parts of wollastonite powder, 0.1 part of zinc carbonate, 15 parts of nanosilicon dioxide, 50 parts of ethyl alcohol and 5,000 parts of water. According to the recycled paper pulp dissolving aid, the water and ethyl alcohol are adopted as a solvent, serve as a carrier of urea, chitosan, the wollastonite powder, zinc carbonate and nanosilicon dioxide, and can be fast dispersed into paper pulp, the function of accelerating dissolving of the paper pulp is achieved, the tearing effect of water flow on recycled paper is improved, and pulping efficiency is improved. More paper pulp fibers can be dissolved out, the effective utilization rate of the recycled paper can be increased, and recycling value can be increased.
Description
Technical field
The present invention relates to waste paper recovery technology field, more particularly, to a kind of recovery paper pulp dissolution aids.
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 response rate of paper pulp fiber.
Content of the invention
It is an object of the invention to provide a kind of reclaim paper pulp dissolution aids it is therefore intended that improving the molten of old paper stock fiber
Go out ratio and dissolution efficiency.
The technical problem to be solved employs the following technical solutions to realize：
A kind of recovery paper pulp dissolution aids are it is characterised in that be made up of the raw material of following weight portion：
0.3 part of carbamide, 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.
Preferably, water used is mixed with other raw materials in the form of frozen water mixing.
Described recovery paper pulp dissolution aids use in the presence of having solid water, it is possible to increase paper pulp rate of dissolution, subtract
Time needed for few waterpower paper pulp.
The invention has the beneficial effects as follows：
The recovery paper pulp dissolution aids of the present invention, with water and ethanol as solvent, and as carbamide, shitosan, wollastonite in powder,
Zinc carbonate, the carrier of nano silicon, can rapidly and uniformly be distributed in paper pulp, play the role of to accelerate paper pulp to burst solution, increase
The effect of tearing to reclaim paper for the current, improves pulping efficiency；Can dissolve more paper pulp fibers, improve the effective of reclaim paper
Utilization rate, improves 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.
A kind of recovery paper pulp dissolution aids, are made up of the raw material of following weight portion：
0.3 part of carbamide, 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.
Preparation method is：
First wollastonite in powder, zinc carbonate are mixed, being ground to granularity is 20-30 micron, then mixes all with nano silicon
Even, obtain mixed material stand-by；
Water-cooled is frozen into ice cube, is then broken into rubble ice, room temperature dissolves and floats all residue ice cubes to water, Ran Houjia
Enter mixed material, carbamide, shitosan, ethanol, stir, that is, obtain the recovery paper pulp dissolution aids that can use.
Should use before ice cube or Sorbet dissolve completely, best results.
Ultimate principle, principal character and the advantages of the present invention of the present invention have been shown and described above.The technology of the industry
The only present invention it should be appreciated that the present invention is not restricted to the described embodiments, described in above-described embodiment and description for the personnel
Preference, be not intended to limit the present invention, without departing from the spirit and scope of the present invention, the present invention also has various
Changes and improvements, these changes and improvements both fall within scope of the claimed invention.Claimed scope is by institute
Attached claims and its equivalent thereof.
