Description
Technical field
The invention mainly relates to recovery and reuse of waste field, and in particular to a kind of old newsprint high frequency recycled fibre pulp
Method.
Background technology
Waste paper, refer to the recyclable regenerative resource discarded in production and living by using, including various high-grade paper, Huang
Paperboard, litter decoration, trimming paper, packing paper, business unit's paper, engineering paper, books and periodicals newspaper etc..In the world, waste paper one
As divide into that Europe is useless, U.S. useless and day is useless three kinds.In China, compared with the cycling and reutilization degree of waste paper is compared with western developed country
It is low.With the development of economy and society, paper usage amount rapid increase, waste paper largely produce.China as second-biggest-in-the-world paper and
The country of consumption of cardboard, paper consumption figure in 2003 are 48,060,000 tons, and the conservative estimation of waste paper yield is 14,000,000 tons, the raw material of paper
The predominantly string such as timber, grass, reed, bamboo, waste paper are otherwise known as " secondary stock ", and most important purposes or fiber return
With production recycled paper products.According to the difference of fibre composition, by paper kind carry out it is corresponding recycle could at utmost play it is useless
Paper resource value.In addition to recycled writing paper produces, waste paper that is low-quality or having mixed other materials also has other extensive regenerating uses:
Produce furniture:The ground such as Singapore, circular elongated rod is rolled into waste paper such as old newspaper, secondhand book periodicals, one layer of plastic paper is wrapped up in outside and makes in fact
With furniture attractive in appearance.Mould product:Paper matrix packing articles can be widely used for the inner packing of product, and alternative foamed plastic is daily
Product or technique special product:The waste paper for being difficult to handle can be raw by crushing, grinding, adding reshaping after adhesive and various fillers
Produce soapbox, footwear box, acoustic celotex board, device paper.Produce civil construction material:Main manufacture heat-insulating heat-preserving material or composite wood
Material, putty material etc..Gardening and agriculture-stock production:Small flower is made after waste paper mashing；Soil quality can be improved in Agricultural production,
And cattle and sheep feed (U.S., Britain, Australia) can be processed into.As fuel:Finland, Germany, Japan are made very in this respect
It is good.Refine waste paper regenerated enzyme:It can be used for deinking after refining regeneration enzyme, produce white recycled writing paper.Produce glucose:Old newspaper
With acid treatment, generation glucose is decomposed after dissolving away fiber.Utilization on chemical industry:CMC, filter aid are produced, with synthetic fibers
Mixture manufacturing industrial wipes；
Although China's waste paper utilization rate (utilization/yield) is up to 49%, the waste paper rate of recovery (yield/consumption figure)
Less than 30%.The import dependency degree of the wastepaper as raw material of China's papermaking rises year by year, is up to 40% within 2003.Domestic waste paper
The rate of recovery does not improve but, and also largely by small enterprise backward in technique to be processed into cardboard, toilet paper etc. low for the waste paper reclaimed
Class product, the resource value of waste paper is not played, also brings serious secondary pollution；Industrialization level it is low have its source in it is useless
Paper regeneration industrial supporting policy lacks dynamics, but Industry Foundation difference and an important restriction factor.Current domestic waste paper recovery
The important bottleneck utilized is the requirement that wastepaper as raw material is all difficult to meet papermaking enterprise in quality or scale.China
Waste paper is simply just divided into a limited number of kind of books and periodicals magazine, newspaper, cardboard, paper bag, blank sheet of paper side etc. by various regions, lacks unified mark
It is accurate；In the case where lacking professional standard and unified supervision, China's waste paper recovery system is very at random, it is difficult to occurs strong
Large-scale waste paper supplier.Mixing for domestic waste paper is transported with small lot, it is difficult to meets the needs of papermaking enterprise large-scale production.For
Stable supply channel and material quality are pursued, big-and-middle-sized papermaking enterprise is actually inevitable as raw material using imported waste paper.
Therefore in order to preferably utilize waste paper resources, environmental protection, promote the development of economy, the present invention have studied one kind side
Just the efficient, method of good, low energy consumption the old newsprint high frequency recycled fibre pulp of the feature of environmental protection.
The content of the invention
