Description

A kind of true qualities bamboo pulp production method and the true qualities paper for daily use produced thereof
Technical field
The invention belongs to pulping and paper-making field, especially a kind of true qualities bamboo pulp production method and the true qualities paper for daily use produced thereof.
Background technology
Initial true qualities paper for daily use is also known as true qualities ecology paper, it is that Shandong paper enterprise proposes, it is to replace traditional pulping process by biotechnology, without any industrial chemicals, raw material is adopted natural ecological timber, vegetable oil, water, starch, is fermented by unique biological, has been inherently eliminated carcinogen and the industrial chemicals harm to health such as the chlorine in bleaching paper for daily use, benzene, fluorescent material.
True qualities paper for daily use, it is adaptable to family, hotel, hotel, various food and drink place, allows all user depart to fall bleached paper and the recycled writing paper harm to human body.
This product, once putting goods on the market, is held in both hands by abroad consumer's heat at first, thus, external true qualities paper for daily use is developed rapidly. Nearly 2 years, domestic unbleached paper started to cause each big paper enterprise to pay close attention to, and falls over each other to develop true qualities paper for daily use miscellaneous, and buff, light brown, Lycoperdon polymorphum Vitt, linen, beautiful jade beautiful jade is all. Current domestic unbleached paper market is also more chaotic, it does not have a unified product standard, and Consumers' Acceptance is yet not high.
In production technology, except producing unbleached paper except bio-pulping method, all the other production methods are also different, sub-sodium/ammonium method, soda processes, sulfate process have, and for tone, it is buff that Ammonium Sulfite Method produces paper pulp, Caustic soda Faxian rufous, conventional Kraft method is greyish white to Lycoperdon polymorphum Vitt. But, all there is certain deficiency in these methods, Ammonium Sulfite Method color and luster is better, but large-scale production is more difficult, the bad solution of environmental issue; Soda processes form and aspect are not good enough, and paper pulp yield is relatively low, relatively costly; Conventional Kraft method tone is less approved by market; Bio-pulping is because lacking elevated temperature processes, and paper pulp seems that some is undesirable in bacterial population index. Therefore, find and a kind of be suitable for the natural color pulp production technology extensive, low cost, low stain, form and aspect are good, safety is high and the true qualities paper for daily use that produces will have good development space.
Bamboo, as a kind of excellent papermaking raw material, is widely recognized as by people, in recent years, due to its natural antibacterial, is increasingly subject to consumer as the articles for daily use and likes, true qualities bamboo pulp paper for daily use is constantly subject to domestic and international consumers. Therefore, the exploitation of true qualities bamboo pulp paper for daily use receives much concern. At present, the exploitation of domestic true qualities bamboo pulp paper for daily use is few in number, and form and aspect aspect has a few class of buff, canescence and light brown. The technology of domestic current exploitation bamboo natural color pulp, the preparation method of an application number 201410121975.X true qualities bamboo pulp fiber paper for daily use, steaming and decocting and oxygen delignification method is adopted to prepare true qualities bamboo pulp paper for daily use, economization bleaching, avoiding the drift agent such as use chlorine, Product Safety improves, and just finds that its tone retains not up to ideal goal from final products, in canescence, not strong to the joyful sense of consumer's vision. Paper pulp prepared by 201410355005.6 1 kinds of bamboo fibres of application number, its preparation method and the paper products made thereof, have employed and first dredge the technique that mill screens pulp washing again, used relatively low boiling temperature simultaneously, paper pulp tone is looked into and is obtained better reservation, but production scene operating environment worsens, pulp washing effect declines, send evaporation black liquid wave hairdressing to decline, alkali collection load increases, and is unfavorable for the raising of production efficiency. Therefore, current true qualities bamboo pulp technology of preparing is Shortcomings in cleaning production, efficient mental retardation production.
Summary of the invention
For the deficiency of the said goods and technology of preparing, it is an object of the invention to provide a kind of efficiently, low consumption, cleaning, low cost true qualities bamboo pulp technology of preparing, a kind of healthy and safe, vision true qualities paper for daily use more preferably is provided simultaneously.
The present invention is achieved in that by a kind of true qualities bamboo pulp production method and the true qualities paper for daily use that produces thereof, including selecting materials, get the raw materials ready, wash material, steaming and decocting, screening, washing, oxidation processes, pulp washing, papermaking, copy paper, it is characterised in that:
