Abstract

The invention discloses a method for making degradable ground film paper from cotton stalks.The method comprises the following steps that 1, the cotton stalks are chopped into material segments; 2, the material segments are sent into a steaming bin for presteaming and then sent into a continuous cooking device for cooking; 3, the cooked materials are sent into a twin screw pulping extruder for twisting and fiber separating, and coarse pulp is obtained; 4, the coarse pulp obtained in the third step is subjected to pulp washing, beating and digestion and then sent into a papermaking machine to be made into the ground film paper.According to the method for making the degradable ground film paper from the cotton stalks, the papermaking efficiency can reach up to 90%-95%, the b/c ratio of waste water produced by the system is high, the biochemical process is easy to achieve, a biological treatment method can be adopted, the obtained ground film paper contains a large amount of nitrogen, phosphorus and potassium and provides nutrients for cotton growth after being degraded, and compared with traditional plastic film, the cost is reduced by about one third.

Description

Cotton stalk makes the method for degradable mulch paper
Technical field
The present invention relates to a kind of method that cotton stalk makes degradable mulch paper.
Background technology
Xinjiang is Cotton in China main producing region, its sown areas of cotton within 14 years, reached the half of the total cultivated area in the whole nation with On, reach 35,000,000 mu.Every mu of cotton field can output cotton stalk about 250 kilograms, full boundary there are about the cotton stalk resource of 8,750,000 tons and may utilize. The way that cotton stalk processes at present is mainly: goes back field and straw power generation etc. after on-site incineration, pulverizing, is all disappointed result.
Often there is the extreme weather such as cool winds, cold spell in later spring in Xinjiang in Spring, for ensureing that Cotton Gossypii emerges in time, preserve soil moisture feelings, Sowing cotton seed has to take covering with ground sheeting to be incubated.Due to plastic sheeting non-degradable, can not reclaim again, so, " white is dirty Dye " increasingly severe.
How to solve " white pollution " problem？Except the recovery of reinforced plastics thin film, find dropping of alternative plastic sheeting Solution mulch film is imperative.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of cotton stalk makes degradable mulch paper Method.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
Cotton stalk makes the method for degradable mulch paper, comprises the steps:
(1) cotton stalk is cut into material section；
(2), after material section feeding decatize storehouse being steamed in advance, it is re-fed into even steam device and carries out steaming and decocting；
(3) material after steaming and decocting is sent into double-screw pulp-milling and is carried out stranding and rub sub-wire, obtains unscreened stock；
(4) unscreened stock of step (3) through pulp washing, pull an oar, divert oneself, remove the gred after send paper machine, manufacture paper with pulp into mulch film paper.
Further, the long 30-40mm, diameter 2-3mm of step (1) material section.
Further, step (2), based on material section weight, adds 2～the potassium hydroxide of 2.5%, 1.5～the ammonium sulfite of 1.8%, 1.2～the sodium tripolyphosphate of 1.5%.
Further, solid-liquid ratio during steaming and decocting is 1:4.5, and temperature is 135～140 DEG C, and the time is 95～100min.
Further, the material elder generation spiral dehydration after steaming and decocting, it is re-fed into double-screw pulp-milling and carries out stranding and rub sub-wire.
Further, when manufacturing paper with pulp, based on ton slurry, adding the corn starch of 120～130 kilograms, 15～20 kilograms of papermaking are wet by force Agent, 10～12 kilograms of paper waterproof moisture proof agents.
Beneficial effects of the present invention:
1, copy paper efficiency height can reach 90～95%.
2, containing substantial amounts of nitrogen, phosphorus, potassium in mulch film paper, after degraded, nutriment is provided for cotton growth.
3, the waste water b/c ratio that system produces is high, can reach about 0.5, easily biochemical, and water processes can use biological treatment Way, specify direction for paper-making zero discharge.
4, technological process is simple, papermaking low cost.Escapable cost about 1/3 compared with tradition plastic sheeting.
