Paper maintenance and the attention points

Paper is printed in one of the important material production, preservation and good management of paper is a very important work. Paper in transport, must not from high to low casting, lest produce parts and the edges of the damage of paper car fluctuation handling the commissions.the lifting forklift truck loading and unloading, into pieces of paper never erect storage and transportation, shall be uniformly lie not in open-air paper in park in time is too long, to timely handling to the warehouse and workshop.

No printing on adjustable wet process of papers, in the workshop or warehouse storage custody should be paid attention to the following questions:

(1) paper moistureproof: paper fibre has very strong suction wet performance, the humidity in the air is very sensitive, paper of moisture content is always as the change of environmental temperature and humidity changes.

(2) stored paper warehouse shall be clean and dry, or directly on printing workshop inside, paper pile high off the ground, from wall to far. Paper library indoor relative humidity is better keep in 60-70 % left and right sides, and the temperature with 18-25 °C be appropriate.

(3) paper to prevent bask in: paper must avoid direct sunlight insolates, paper contains lignin does not light resistance, otherwise will because the moisture is paper evaporate and sent fragile, yellow, also can make paper warping deformation, have more very person will be unable to use. The window of the store try to build by laying bricks or stones highs, glass besmear becomes white, or install a curtain avoid light, is to prevent sunlight penetration, especially containing lignin more newsprint, such as the sun insolates TuBanZhi in long-term become yellow, brittle, pulverization badly.

(4) paper to prevent heat: paper should not be stored in high temperature place. Normally, when indoor temperature over 38 °C high temperatures, paper surface strength will significantly reduced, and warpage, especially the glossy paper, white paperboard, the gold card, the silver cardboard high-grade paper, due to such as paper coated with a layer of white warp size and other pigment by pressing the light and become. High temperature will make pulping, pigment melt into pieces, paper and bonding between adhesion, become waste paper.

(5) paper folding: paper storage to prevent out flat pile qi, absolutely avoid a folding Triassic placement, pile up every make paper placed note differences between disjunctive, must not make both ends of the paper, or paper crisscross bulgy extruding part yi deformation, bending or metamorphism, easy fouling and rupture.

(6) paper guangzhou2005 prevent reverse: paper pile in warehouses and printing paper counter, warehousing and placed in paper cutter process should be recognized paper, paper guangzhou2005 dual facing up and rough face downwards, avoid the printing will be positive and negative make topsy-turvy.

(7) paper to fire: paper inflmmables, printing enterprise is the fire key units, so ", the bud, responsibility than mount tai ", safe production is very necessary. Paper in storage, printing and binding, cutting each procedure to the work site should be neat and clean, warehouse workshop forbid fireworks.

(8) paper storage should be off the ground, metope 30cm away from 20-30cm, don't let paper on the light is strong places lest paper from the paper mill yellow of purchased paper to stage by stage, the partial pile up, establishes the perfect into library card system, the paper to quickly put in storage, in the air caused the paper to avoid moisture damp when use storage time limit according to the paper, the storage period length of outbound reasonable use of paper poetry, prevent paper storage period too long become fragile, become yellow, pulverization metamorphic problem warehouse ventilated breathe freely, warehouse paper pile up to clean and tidy, not to throw, put in disorder, regularly to make a kind of selective examination paper safekeeping conditions, in conditional manufacturer had better install air-conditioning equipment, effectively control the temperature, the humidity in the warehouse, guaranteed quality, improve printing paper product quality.
