Abstract
A processing method of paper for rice covering cultivation relates to the technical field of paper making, and particularly relates to a processing method of agricultural paper suitable for organic rice covering cultivation, which is prepared by taking secondary fibers such as waste packing materials and part of primary fibers as main raw materials, matching with specific auxiliary materials, functional auxiliaries and biological agents and processing by a special method. The method comprises the following steps: (1) pulping; (2) adding auxiliary materials; (3) papermaking; (4) and (5) finishing. The paper film is covered with the mulching film paper to cultivate the rice, the paper film is not damaged before ridge sealing in the rice growth period, and the effect of inhibiting field weeds is achieved under the condition that no herbicide is used. And has the functions of saving water, increasing temperature and increasing yield; in the late growth stage of rice, namely 40 days later, the strength of the paper film gradually disappears, and the paper film is naturally decomposed into organic matters, so that the effects of loosening soil and improving soil are achieved.
Description
Technical field
The present invention relates to pulp technology for making paper; Specifically be that to adopt secondary stock such as discarded packing material and part fibrillation be main raw material; Be equipped with specific auxiliary material, function additive and biological agent, and process the processing method of the agricultural papers that are applicable to the organic paddy rice culture underglass with specific process.
Background technology
Adopt covering with ground sheeting to carry out arviculture, have plurality of advantages such as to improve soil temperature and humidity, promotion precocity and raising output, be widely used in China.The conventional plastic mulch film is trapped in and has a strong impact on soil texture in the soil owing to be difficult for to reclaim, be difficult for degraded, and causes " white pollution ".And but there is complex manufacturing in the mulch film paper of natural degradation at present, the more high shortcoming of cost, and particularly for rice cropping, since high humidity, the shortcoming that common ground film paper also exists rot-fastness to differ from.
Summary of the invention
Technical problem to be solved by this invention is: provide that a kind of production technology is simple, cost is low and the processing method of the paper for rice mulching cultivation that rot-fastness can be strong.
Technical solution of the present invention is: it is to carry out according to the following steps:
(1), by mass percentage; 40% true qualities sulphite softwood pulp is pulled an oar in beater, discongest 60% waste paper shell with pulper, screen through defibrator; Good paper pulp is pulled an oar with beater, and mix in stock tank with true qualities sulphite softwood pulp the back;
(2), by mass percentage; Add dispersion rosin size, 4.5～5.0% aluminum sulfate solutions, 0.8～1.0% wet strength agent account for true qualities sulphite softwood pulp and waste paper shell sum of the two 0.5～0.8% respectively, fully mix the back with stock pump squeeze into copy before the stock tank preparation copy paper;
(3), slurry get into after through condiment case, slurry-stablizing case web part of paper machine dewater to concentration be 2%～4%, again through the mechanical expression roller further dewater to concentration be 30%～40%, the l Water Paper page or leaf forms page through cylinder dried again, coils into roller;
(4), be packaged into the finished product paper bowl after the rewinding punching;
Said beating consistency is: 5.0～5.5%; True qualities sulphite softwood pulp making beating beating degree is 28～32 degree, and weight in wet base is greater than 4 grams; Waste paper shell making beating beating degree is 32～36 degree, and weight in wet base is greater than 5 grams.
Dryer temperature is 105～108 ℃ in the said step (3).
Technique effect of the present invention is: it has higher rot-fastness ability and good agronomy adaptability; Adopt mulch film paper culture underglass paddy rice; The paper film is not damaged before sealing the ridge in growth period duration of rice, under the situation of not using herbicide, plays the effect that suppresses weeds in field.And have water saving, heat, production-increasing function; At the paddy rice late growth stage, after promptly 40 days, the paper film strength fades away, and natural decomposition is organic, plays loose soil, the effect of improving the soil.
Description of drawings
Accompanying drawing is a process chart of the present invention.
The specific embodiment
The processing method of paper for rice mulching cultivation, carry out according to the following steps:
(1), the making beating: by mass percentage, with 40% true qualities sulphite softwood pulp pack into No. 2 and No. 3 beaters in pull an oar, put into stock tank after accomplishing fluently No. 3; Pack 60% waste paper shell into and discongest in the hydrabrusher; Screen through defibrator after discongesting; Good paper pulp gets in No. 1 beater and pulls an oar, and puts into stock tank after accomplishing fluently No. 1, and with stock pump paper pulp being squeezed into No. 3 stock tanks again mixes with true qualities sulphite softwood pulp;
(2), add auxiliary material: by mass percentage; Add dispersion rosin size, 4.5～5.0% aluminum sulfate solutions, 0.8～1.0% wet strength agent account for true qualities sulphite softwood pulp and waste paper shell sum of the two 0.5～0.8% respectively, fully mix the back with stock pump squeeze into copy before the stock tank preparation copy paper;
(3), copy paper: slurry passes through to get into web part of paper machine dehydration (pulp density 0.1%～0.3% behind condiment case, sand trap, the slurry-stablizing case; Dehydration back concentration is 2%～4%); Again through mechanical expression roller further dewater (pulp density reaches 30%～40%); The l Water Paper page or leaf forms page through drying cylinder (using Steam Heating) dry (the paper mass dryness fraction reaches 91%～93%) again, coils into roller;
(4), finished product: be packaged into the finished product paper bowl after the rewinding punching;
Said beating consistency is: 5.0～5.5%; True qualities sulphite softwood pulp making beating beating degree is 28～32 degree, and weight in wet base is greater than 4 grams; Waste paper shell making beating beating degree is 32～36 degree, and weight in wet base is greater than 5 grams.
The said paper slip spare of copying: dryer temperature is 105～108 ℃.
Hole knockout: punch during rewinding.
Embodiment 1:
By mass percentage, 60% waste paper shell is discongested in the true qualities sulphite softwood pulp making beating with 40%, and the paper pulp that screening is good mixes in stock tank with true qualities sulphite softwood pulp with beater making beating back; Add auxiliary material dispersion rosin size 0.5%, aluminum sulfate solution 4.5%, wet strength agent 0.8%, fully mix the back with stock pump squeeze into copy before stock tank prepare to copy paper.
