Abstract
The invention discloses a lightweight paper made from a high-proportion bamboo pulp and a making method of the lightweight paper and relates to the papermaking field. The lightweight paper is prepared from a mixed pulp of a chemical bamboo pulp, a mechanical pulp and a long-fiber CTMP pulp in the weight ratio of (50-55): (45-40): (5-10), and the following accessories in percentage by weight: 1.2% of starch, 10% of talcum powder, 0.6%-0.8% of dispersed rosin size, 6%-7% of aluminum sulfate, and 0.2kg/t of polyacrylamide PL1510; in the papermaking process: the indices, such as beating degree and ISO whiteness, of the chemical bamboo pulp and the mechanical pulp before blending are controlled; the following quality indices of the pulp applied to a screen are controlled: pH value of 5.8-6.2, concentration of 0.7-0.9% and beating degree of 47-55degree S. According to the lightweight paper, the high-proportion bamboo pulp is adopted, the raw material range of the lightweight paper is expanded, the product cost is low, the product is pure environmentally friendly and green, and the pollution load is low.
Description
Technical field
Match somebody with somebody the light paper and its pulping method copied the present invention relates to pulp technology for making paper, especially a kind of bamboo pulp at high proportion.
Background technology
Low weight printing paper as a kind of new printing, because it has bulk higher, deflection, opacity,
Printability is good, is more widely deployed for the printing of books and periodicals.Printing paper used by current publishing house, absolutely major part are still used
Wood-free paper；Although the high-grade printed matter in part uses light-duty Cultural Paper（Cover and agree paper）, it is also at high price to external import；According to statistics, I
State is annual to double 1,600,000 tons of the glue printing paper of external import, and 500,000 tons of the light-duty high-grade culture paper of import is covered and agrees 300,000 tons of paper, every year
15,300,000,000 yuan of foreign exchange need to be consumed.Therefore import wood-free paper and light-duty Cultural Paper are substituted with domestic light-duty Cultural Paper, can be saved for country
Substantial amounts of foreign exchange.Current domestic production low weight printing paper enterprise is fewer, and the light paper of these enterprises production is mostly
APMP slurries are with copying part needle mechanical pulp and part needle chemical pulp production cost is higher.
The content of the invention
Problem to be solved by this invention is to provide the bamboo pulp at high proportion that a kind of pollutional load is small, product cost is low and matches somebody with somebody what is copied
Light paper and its pulping method.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
Slurry is：Chemical bamboo pulp, machine slurry and long fibre CTMP slurries, slurry weight ratio are chemical bamboo pulp：Machine is starched：Long fibre
CTMP slurries are 50~55：45~40：5~10；
Auxiliary material percentage by weight consumption is：Starch consumption 1.2%, amount of talc 10%, dispersion rosin size 0.6%~0.8%,
Aluminum sulfate 6%~7%, polyacrylamide PL1510 0.2kg/t paper.
In above-mentioned technical proposal, more specifically scheme can also be:Described dispersion rosin size consumption is by degree of sizing
The amount that 0.5mm is added.
The light paper of such scheme, its pulping method is：
A, slurry are chemical bamboo pulp, machine slurry and long fibre CTMP slurries, and slurry weight ratio is chemical bamboo pulp：Machine is starched：Long fibre
CTMP slurries are 50~55：45~40：5~10；
The quality index of B, preceding chemistry bamboo pulp with slurry and machine slurry：
Deduction degree：30~35 ° of SR of chemical bamboo pulp, machine starches 34~39 ° of SR, and long fibre CTMP starches 35~40 ° of SR
ISO whiteness：Chemical bamboo pulp 80~84%, machine slurry 65~70%, long fibre CTMP slurries 68~75%；
C, supplementary product consumption：Starch consumption 1.2%, amount of talc 10%, dispersion rosin size 0.6%~0.8%, aluminum sulfate 6%~
7%, polyacrylamide PL1510 0.2kg/t paper；
The quality index of D, online slurry：PH value 5.8~6.2, concentration 0.7-0.9%, 47~55 ° of SR of deduction degree.
Due to using above-mentioned technical proposal, the present invention compared with prior art, to have the advantages that：
1st, the present invention expands the raw material range of light paper using bamboo pulp at high proportion, and product cost is low.
2nd, pure environment-friendly and green product is belonged to, pollutional load is small.
Specific embodiment
Below by specific embodiment, the invention will be further described, but the invention is not limited in these embodiments.
Embodiment 1：
