印刷打印纸的保养
作者:admin 来源:http://www.sdhzyw.com 发布时间:2019-3-4 18:32:57 浏览次数:190
咱们的打印纸如果保养不得当,会给咱们的印刷作业带来诸多不便。为了保证咱们的正常运用,下面小编就简略给我们介绍一下打印纸的保养方法。
If our printing paper is not properly maintained, it will bring a lot of inconvenience to our printing work. In order to ensure our normal use, the following edition will give us a brief introduction to the maintenance of printing paper.
(1)纸张防潮:纸张纤维具有很强的吸湿性能,对空气中的湿度是十分敏感的,纸张中的水分含量总是随着环境温湿度的改变而改变。
(1) Paper moisture-proof: Paper fiber has a strong moisture absorption performance, is very sensitive to humidity in the air, the moisture content of paper always changes with the change of ambient temperature and humidity.
(2)贮存纸张的仓库应当清洁枯燥,或许直接放在印刷车间里面,纸堆离地上要高,离墙壁要远。纸库的室内相对湿度保持在60-70 %左右,而温度以18 - 25 ℃为适宜。

(2) The warehouse where paper is stored should be clean and dry. Perhaps it should be placed directly in the printing workshop. The stack of paper should be high on the ground and far from the wall. The indoor relative humidity of paper storehouse is about 60-70%, and the temperature is suitable at 18-25 C.

(3)纸张要防晒:纸张避免阳光的直接暴晒,纸张中含有木质素不耐光,否则将因纸张中的水分被蒸发而发脆、发黄,一起会使纸张翘曲变形,更有甚者将无法运用。仓库的窗户尽量砌高点,玻璃涂成白色,或许安装上窗帘避光,就是为了避免太阳光的透射,尤其是含木质素多的新闻纸、凸版纸等遇太阳光长时间暴晒变黄、变脆,粉化厉害。
(3) Paper should be sunscreened: Paper should avoid direct sunshine exposure. Paper containing lignin is not light-resistant. Otherwise, it will be crisp and yellowing due to the evaporation of water in the paper. Together, it will make the paper warp and deform, and even worse, it will be impossible to use. The windows of the warehouse are as high as possible, and the glass is painted white. Maybe curtains are installed to avoid the transmission of sunlight. Especially for newsprint and relief paper which contain more lignin, when exposed to sunlight for a long time, they become yellow, brittle and powdered.
(4)纸张要防热:纸张不应当贮存在温度过高的地方。一般情况下, 当室内的温度超过38℃高温时,纸张表面强度则会显着下降,并且翘曲变形,尤其是铜版纸、白卡纸、金卡、银卡纸等高档用纸,因为纸面涂布了一层白色浆料和其他色料经压光而成的。温度高则会使浆料、色料熔化粘结成块,纸张与纸张之间粘连,变成废品。
(4) Paper should be heat-proof: Paper should not be stored in places where the temperature is too high. Generally speaking, when the temperature in the room exceeds 38 C, the surface strength of paper decreases significantly, and warpage deformation occurs, especially for high-grade paper such as copper plate paper, white cardboard, gold cardboard and silver cardboard, because the paper surface is coated with a layer of white pulp and other colors which are calendered. High temperature will melt and bind pulps and colors into blocks, and paper and paper will become waste products.
