[keyword] metamorphic starch, papermaking auxiliary, be not lumber fiber papermaking, intensifier (papermaking)
[achievement brief introduction]
Papermaking chemical is the important category of new field of careful chemical industry, its study development is in door of Chemical Industry Department, application is in light industrial papermaking, belong to alternate course, maintaining close cooperative relationship for a long time. The 3 projects place that by national “ science and technology of 95 ” key tackles key problem makes this item. Choose in considering to develop combine function in person with plant fiber good, resourceful and reproducible is natural and amylaceous for main raw material, adopt the method that the element devises, the chemical recipe that differs according to the different choice of utility and engineering technology, the normal temperature catalysis that developed papermaking of blame lumber fiber to use product of metamorphic and amylaceous series and original creation changes cleanness to manufacture technology continuously, content of this craft science and technology is high, economic benefits is good, the sources of energy is used up low, environmental pollution is little, have wide market perspective. Subproject 1: Blame lumber fiber is special intensifier, have multivariate molecular structure, fighting while foreign matter is disturbed, support aids extortion era radical is round, can improve the quality that is not lumber fiber paper apparently, its physics intensity rises rate amount to 15 ％ - 35 ％ , or in maintain the circumstance with paper changeless intensity to fall, managing wood pulp 10 ％ - 35 ％ , have international banner level, already obtained a country to invent patent (ZL99113918.6) . Subproject 2: Straw pulp papermaking is used aid filter take a dose, have network structure, filter water speed and fine fibril and filling rise to staying to lead in papermaking process, among them filling leaves a rate to raise 10 ％ - 30 ％ , papermaking specific power consumption reduces 5 ％ - 10 ％ . White water chroma can drop 20 ％ - 30 ％ , do not reduce paper look-through and intensity at the same time, already obtained a country to invent patent (ZL99113919.4) . Subproject 3: Newspaper wet department is special chemical, can fight lignin interference, make newspaper intensity raises 15 ％ - 20 ％ , make common newspaper upgrades thereby for offset print newspaper, the wood pulp when can making paper quality measures second birth news to achieve or be not added more than especially copies additive newspaper quality standard, still can increase paper grey share, reduce Bai Shuinong to spend 10-30 ％ , the measure that implements to add chemical through wet ministry first in home improves newspaper quality; Already obtained a country to invent patent (ZL99113920.8) . Classics expert appraisal thinks: The product that this project develops gets used to China to be not the national condition of papermaking of lumber fiber, regenerated fiber, technology is advanced and sound, function achieved international to precede or international is advanced level, product fill home is blank. The product of these 3 projects all is place of Chinese papermaking industry to be badly in need of, can improve paper quality apparently, reduce dosage of papermaking cost, managing wood pulp, protect silvan natural resources, can reduce the BOD in paper mill waste water and COD cost apparently at the same time, have beneficial result of apparent environmental protection, belong to product of green environmental protection, and all already industrialization, have remarkable economy and social beneficial result. Already sold a product up to now many tons 25 thousand, produce all sorts of excellent paper 2.5 million tons. Home includes industry of green hill paper, morning to cry the much home such as industry of industry of paper of industry of industry of industry of Han Yang paper, golden wall paper, Tian Hong paper, Hua Tai, silver-colored columbine paper appears on the market company inside mill of about a hundred paper already applied, user report is favorable, have wide market perspective.
