Abstract

The invention discloses a papermaking flow aid which is commonly used for white paper production in the papermaking industry and can be used for enabling fibers in pulp to be relatively even, so that bonding points among the fibers and between each fibers and corresponding macromolecule are increased, so as to improve the paper dry strength; the performance indexes such as the folding strength of paper can be effectively improved; the whiteness, the uniformity, the smoothness and the like are improved to a certain extent; meanwhile, the dual characters of a paper sheet are improved; the printability is also improved. The papermaking flow aid disclosed by the invention comprises main components of dry polyacrylamide powder, analytically pure sodium hypochlorite, analytically pure hydrochloric acid, analytically pure caustic soda and water which are raw materials allowed to be used in the chemical industry in China.

Description

A kind of papermaking glidant

Technical field

This product belongs to chemical field.

Background technology

Existing paper technology is not if used the papermaking glidant can cause paper quality low, the slurry consumption is high, invention production papermaking glidant thus, product of the present invention is mainly the modified cation polyacrylamide, and compound other active ingredient, be weak cation, contain the various active base in strand, after correct the use, can make paper quality significantly improve, and the slurry consumption reduces by 10%, thereby make cost.

Summary of the invention

For addressing the above problem, the invention provides a kind of papermaking glidant, its technical scheme is: solid content >=88%, 20 kilograms, the polyacrylamide dry powder of molecular weight: 600-2000 ten thousand, analyze 3000 milliliters of pure clorox, analyzes 4000 milliliters of pure hydrochloric acids, analyze pure caustic soda 500 grams, 1000 kilograms, water.

The specific embodiment

1000 kilograms, water is added in chemical reaction kettle, by Steam Heating, to Celsius 45, spend, drop into while stirring polyacrylamide dry powder, add the caustic soda after 500 grams dilute after stirring, add after 4 hours and analyze 3000 milliliters of pure clorox, add after 4 hours and analyze 4000 milliliters of pure hydrochloric acids, the Plastic Drum of finished product being put into to 25 kilograms after 15 minutes from chemical reaction kettle is standby.Outward appearance is ivory-white stringy liquid; PH value 3～4; Solid content >=2%; Water dispersible: but infinite dilution is in water; Storage period: room temperature is placed more than half a year not gel, is never degenerated, cationic.Operation principle and using method:

Product of the present invention can with fiber on hydroxyl produce intermolecular interaction (take static as main) and Hydrogenbond.

Its Main Function is that in making to starch, fiber is more even, and causing between fiber reaching binding site between fiber and macromolecule increases, thereby improves the paper dry strength.Product has and significantly increases the dry use of pretending, and can effectively improve the performance indications such as folding strength of paper.When consumption is 0.5%, become paper tensile strength and tearability can improve 15% one 25%, and folding strength, whiteness, the uniformity, smoothness etc. all are improved to some extent.Burst index improves 25%.This product is as retention agent, can increase keeping of fiber fines and filler in slurry, in water, fiber fines concentration reduces, the loss loss of fiber and filler reduces, to make ton paper grout consumption reduce, improve the dual character of page simultaneously, intensity, whiteness, the smoothness of page are all increased, improve its printing adaptability.In addition, because the raising of filler retention and filtrating aid function make the l Water Paper page become large at the dewatering speed of wet end and press section, thereby can improve paper machine speed, increase output, and woollen blanket is also more clean, has extended service life, and the consumption of reduction drying section steam.This product is of many uses, can be used for writing paper, gelatine printing paper, newsprint, etc. the production of paper kind.Fortifier with before add the with slurry pond and stir, consumption 10% after should diluting 20 times.With producing multiple efficacies; Increase paper strength, reduce hair and powder dropping; Improve the retention of filler, fiber fines, sizing agent, thereby can improve ash content, opacity, degree of sizing, the paper smoothness of paper, dwindle the page two sides poor; Reduce machine water concentration, save the slurry consumption; Improve drainability, save the energy consumption of Dryer Section of Paper Machine; Reduce production costs, increase economic efficiency.
