Paper investment analysis of environmental protection that do not weave cotton cloth
The paper industry is a traditional trade with a long history, but because of the flourishing development of the petroleum chemical industry over the past 30 years, research and develop the substitute of a great deal of traditional paper, can divide into the traditional wood pulp paper industry and not the wood pulp paper industry.
Paper industry sketches the traditional wood pulp
The traditional wood pulp paper industry follows the historical orbit to raise one by one, the industry which say to be quite ripe, present technology is to tend towards maximization, speed and high-quality development that melted, in order to reduce the manufacturing cost.
Cut and cut the herb or cut down the trees, cut a wood chip in manufacture procedure of the traditional wood pulp paper industry, add strong acid, high pressure cook, make fine to soften, not precise and pure, should make the waste liquid taking place commonly called as " the black liquid ".
Meticulous fibre pure white for to ask, must join strong bleaching agent, wash by a large amount of branch water and then after bleaching, then send the paper copying machine, copy out the paper material of various kinds of uses, is passing different processing procedures of back segment, it is for consumers to select for use to produce all kinds of paper products.
Because the traditional wood pulp paper industry of the human worry cuts down the forest in recent years, cause the earth to be ecological balance system unusual, produce Cheng arrange black liquid that come out and contain a large number of waste water of bleaching agent also pollute rivers and creeks and ocean seriously, so on one hand advocate using by " recycled writing paper " of reclaiming or " retrieving the paper ", invest the a large amount of fund and manpower, the treatment way to improve " black liquid and waste water " on the other hand, therefore has raised the manufacturing cost of the paper.
Increase as population increases and living standard, industrial level improve because of the consumption of the paper product, there is surprising rate of increase every year in the paper industry, though the economic development of the world has shrunk in the past ten years, but there is growth of certain proportion in the paper industry.
It is not the wood pulp paper industry that sketches
The traditional wood pulp paper industry cuts down the forest and discharges " black liquid " and " waste water of bleaching agent ", cause the ecological balance of the earth to be unusual, and pollute the ocean and rivers and creeks, the mankind has already made great efforts to be improving, and slightly successful, but population's increase and living standard improve, the demand for the paper is still
Improve constantly, but in order to reduce the ecological balance of cutting down the forest and safeguarding the earth, it is " not the wood pulp paper " to impel the advanced country to research and develop with higher speed, as its name suggests, this paper does not include the fibre of the wood pulp, but function its or similar as traditional wood pulp paper, so needn't cut down the forest, make Cheng for water pollution issue.
The petrochemical industry has grown vigorously in the past 30 years, have produced all kinds of artificial resin, cooperate with natural fiber, ore powder, glue wood pulp paper, can replace wood pulp paper, offer to P, the earth of environmental protection quite heavily.
On the market at present is not that the paper name of wood pulp has PP, PE to formate paper, synthetic fibers people's papermaking etc..
Making one relatively proves:
Traditional wood pulp paper, formating the paper modernly, when being already unable to meet user's demand, a new one weave cotton cloth environmental protection paper, develop on one hand towards this, consider environmental protection cost, raw materials, processability, market person who accept, future, plural use, wait for a great deal of factors, estimating in advance can have been substituted in an all-round way gradually, for because of in conformity with market multi-functional demand, simple application of paper already unable to satisfy, new-type to weave cotton cloth environmental protection paper, is it formate function of paper generally to possess, and u generally formates the unexistent characteristic of the paper even more, whether such as exceed light quantity and high strength, oversize width, now 3 kinds of paper comparative analysis as follows.
Manufacture the comparison of the procedure
