Color offset printing paper, production technology, the advantages and


Anti-myopia books of similar hue, from the mechanism of human vision and visual environment is closely related to start with the main color to yellow, in the frequency range of light to light with minimal color vision caused by the strongest and only Asian in the brightness of white light ,[link widoczny dla zalogowanych], makes eyes at the same time get to play two visual features, so that to reduce to a lower degree of visual fatigue, people's eyes in a good visual environment, simple and effective prevention of myopia. In addition, paper-making enterprises, from production than the production of color printing paper white offset paper with a quantitative, low cost, mainly to reduce the consumption of bleaching agent bleaching stage, but also the middle of wastewater sludge to reduce pollution, benefit environmental protection. Also in the paper quality, since the drift rate is low, to reduce fiber damage, the increased strength of the paper, and to a substantial increase in the opacity of the paper, to avoid the \This paper is reduced for the same purposes provided the conditions of quantitative conservation of raw materials. Here is our color printing paper production technology and quality indicators (compared with pure white) briefing. First, the main production process (a) of the material ratio l, bleached reed pulp and reed pulp brightness cooking method 2, imported coniferous pulp surgery surgery surgery pulp brightness pulp brand origin (b) of the main process 1,[link widoczny dla zalogowanych], 85% bleached reed pulp 70% a 72% caustic soda method l5% 88% 92% Canadian solar license for a Fort Once sprouts l Ao Bu - called the Castle! whole plastic mat Ao Bu H AU - Turn vertical area urgent - a Gui urgent - + pressure set down port j {; Xiao Zheng tM # ● - + circle - + Marina ugly -,[link widoczny dla zalogowanych], garden - a garden of a nursery + A solid turn hollow cavity surface-po - + Gui trapped - + Marina Gui Bu a circle Note: Dyeing slurry tank to be filled in order: Add the first mixture of wood pulp and reed pulp, dispersed rosin added, stirring after 20 minutes followed by cycling added dyes. 2,[link widoczny dla zalogowanych], imported wood pulp operation l -. . I2m water slurry machine 3 Stanford syrup too taper machine (series) I ---. . I plasma pool (with reed pulp mixed units) l (c) beating 1, reed pulp beating degree 2 wet weight, wet weight of pulp beating degree 5O Double Disc Grinding 3 sets (series) 2.5-3g38 ± 2osR4-4. 5g65-70. sR23 \6%, 5% aluminum sulfate. 2, the surface sizing compound formula oxidized starch: polyvinyl alcohol as a 5: l concentration of 5% of the sizing compound temperature 50-6o. C (e) to be filled l, 2, 2.5% talc, dual phosphorylation of starch 1% (according to the proportion of fine powder was added in solution) 3, brighteners 1 roundworm / t pulp 4, PAM dosage concentration of 0.02% 0.1% (f) the preparation of yellow dye (basic) 150-250g / t pulp rose essence (basic) 12-20g / t pulp amount of alkali blue lake (3-5g / t pulp) amount of tannic acid Shun-piece yellow roses added a solution Seiichi basic Sky Blue Wren temperature 55-60% 200 mesh sieve mesh requires three barrels of the three dyes were used to mixing in the required temperature, dissolved by the order to join. Second,[link widoczny dla zalogowanych], the color of adhesive tape production note l, the amount of the dye hue according to the paper or the user requirements proud of small adjustments. 2, the pH of dye selection method in accordance with their chemical pulping and papermaking Conditions. 3, control the dryer temperature curve. 4, the hardness of the pulp is relatively stable. 5, brighteners and dyes measurement must be accurate to avoid chromatic aberration. 6, the strict control of slurry wash degrees. 7, the loss ratio of pulp to be uniform, to avoid the color fluctuations. 8, the recovery of white water and on the amount of slurry pH value should be stable Bute. Third, the same quantitative color offset printing paper and white offset paper quality indicators shown in table 1 Table 1 \Note: Data for the two papers from each of six samples measured after the index average. Yueyang Paper Group's leading products at the same time pay attention to, actively Paper on the development of downstream products, has successfully developed in the modified starch and electrostatic copy paper, the early September, \and computer printing paper production line officially put into operation, and after inspection of product quality are satisfactory. Following the end of August the company successfully developed a fluorescent whitening agent for paper, the September 7, ll million investment in computer printing paper production line to achieve a successful production, the production line is mainly produced by the No machine 55g / m: high-quality books and paper bag as the raw material side, Nissan 200 cases. Office to meet the needs of the company, sold outside the province. Put into operation the same day, Jiangxi Nanchang customers bought just under 2,000 cases of computer printing paper production line. Fang Minyan
