Background technology
A kind of daily consumption article commonly used of cultural paper still, is in psychologically to the needs of brightness and to the demand of some physical indexs, adopts the paper pulp manufacturing based on bleached wood pulp usually.Some paper plant when the preparation offset printing paper, also adopts straw pulp to substitute wood pulp, so that reduce cost for saving timber resources both at home and abroad at present.But as cost with any sacrifice in performance.
China's culture paper market is pursued high whiteness always, continued trend of rising in these several years in addition, the slurry of China's cultural paper is owing to have a large amount of straw pulps, change machine slurry or deinking slurry, the fibrous raw material whiteness is relatively low, the fines content height, this causes the consumption of brightening agent to increase, and has increased the papermaking cost.And no matter be straw pulp or wood pulp, all adopt bleach chemical pulp as paper making raw material.Because adopt bleached pulp, bleaching process will cause tremendous influence to environment.In addition, bleaching process also will produce environmentally harmful chemical substance.Mainly adopt whiteness than higher paper printing for existing textbook, blank sheet of paper is opened visible reflection of light stronger, particularly the light wave reflectivity to different frequency is more even, because this strong reflection, font contrast height causes that visual fatigue is bigger, and yellow paper reflection spectrum is single, intraocular is looked road and visual center, and to bear little impression big, produces the visual effect height, is difficult for producing visual fatigue.CN99108565.5 discloses a kind of prevention because of reading and cause the books of myopia, and its light of the paper that existing books adopt reflects contrast height, and ruddiness or long wave spectral reflectivity height easily cause visual fatigue and kopiopia, and easily cause myopia.This invention adopts its spectral reflectivity peak value below 580 nanometers, and the books that the lower paper of the reflectivity of the light wave frequency range more than the wavelength of respective value is made, regulatory demand in the time of can reducing read-write, reduce the spread effect of long wave light, suitably reduce aberration and suitable contrast can be provided eye.
There is the color of some book suitable for outside reading paper also to adopt faint yellow on the market, industrial analysis from papermaking, be that straw pulp or wood pulp are gone later to be coloured to the color that is fit to suitable vision again through bleaching, this method both operation is loaded down with trivial details, paper cost height is that paper pulp causes the pollution main cause to environment at bleaching process simultaneously.Association with pulp bleaching mainly is divided into chlorine bleaches technology and chlorine-free bleaching technology at present, and for example the bleaching of wheat straw chemical pulp adopts hypochlorite singing stage bleaching or CEH to float for three sections at present.Bleached pulp brightness is low, intensity difference, bleaching blowdown flow rate are big, and contains multiple carcinogen such as chlorination phenols in chlorination section and hypochlorite section waste water, and these waste water can not reclaim and be used for washing and join cooking liquor, its waste water severe contamination ecological environment.The bleaching agent that chlorine-free bleaching uses is many, and in order to reach a lot of bleaching effects, Extended Delignification is wanted in boiling before floating, and is relatively stricter to the requirement of paper pulp before floating, and improper when procedure Selection, condition is controlled when bad, the quality of influence slurry.
The used paper of whiteness height of the text paper of prior art or outside reading, cause visual fatigue easily, especially for students in middle and primary schools, eyesight very easily is subjected to the influence of external environment, and no matter prepare the used slurry of these paper at present is that wood pulp or straw pulp all will be bleached it, strengthens its whiteness, perhaps is coloured to warm colour after the bleaching again, may also have harmful material in the paper that obtains, its cost is also than higher.
