    印刷厂在纸张保管中要注意什么?

    纸张是印刷厂的重要材料之一,因此保管好纸张非常的重要。印刷厂在保管纸张时总结一下6条经验:
    Paper is one of the most important materials in printing plants, so it is very important to keep the paper well. The printer summarizes six experiences in keeping paper:
    (1)运纸时切勿从高处向下抛掷,以免发生散件和损坏纸张。纸不要竖立,尽可能平放。卷筒纸的堆垛不应过高,以免压坏纸边或纸芯;堆垛过高还会发生人身事故。搬运时禁止使用铁钩。
    (1) Don't throw the paper downward from the top to avoid the occurrence of loose parts and damage to the paper. Paper should not stand upright, as flat as possible. The stacking of drum paper should not be too high to avoid crushing the edge or core of the paper; if the stacking is too high, personal accidents will occur. It is forbidden to use hooks in handling.
    卷筒纸应按箭头指向滚动推送。
    The reel paper should be rolled and pushed according to the arrow pointing.
    (2)露天存放时间不要过久,要及时运进仓库储存。
    (2) Open storage time should not be too long, it should be shipped to warehouse in time for storage.
    (3)防潮。纸张吸湿性强,对空气湿度非常敏感。纸张中的水分含量是随着空气的湿度而变化的,所以贮存纸张要选择清洁干燥的地方。纸张堆放时,要垫搁脚。不能紧贴墙壁堆放。存放纸

    (3) Moisture-proof. Paper is highly hygroscopic and sensitive to air humidity. The moisture content of paper varies with the humidity of the air, so the paper should be stored in a clean and dry place. Paper should be put on the foot when stacking. Can't stack close to the wall. Storage paper

    张的库房和车间的相对湿度最好保持在60%~70%。
    The relative humidity of Zhang's warehouse and workshop should be kept between 60% and 70%.
    (4)防晒。纸张含有木质素,要避免阳光直接曝晒。纸张曝晒后纸中水分蒸发,纸张变脆或者变形,严重时不能上机印刷。
    (4) Sunscreen. Paper contains lignin, so avoid direct sunlight exposure. After the paper is exposed to the sun, the moisture in the paper evaporates, the paper becomes brittle or deformed, and can not be printed on the machine in serious cases.
    (5)防热。纸张贮放时温度不易过高。超过38℃时,纸张的强度显著下降,尤其铜版纸类会粘结成块,变成废品。存放纸张的库房和车间的温度在18~20℃为宜。
    (5) Anti-heat. Paper storage temperature is not too high. When the temperature exceeds 38 C, the strength of paper decreases dramatically, especially the copperplate paper will be agglomerated and turned into waste products. The temperature of the warehouse and workshop where paper is stored should be between 18 20 C.
    (6)防折。纸张折包堆放时,要绝对避免一折三叠地堆放。堆放时纸的四边不可交错凸现,否则会使凸出的部分破裂、起绉、变色等,因此纸张要码放整齐。
    (6) Anti-folding. Paper folding and stacking, we must absolutely avoid folding and stacking three times. When stacking, the four sides of the paper should not be staggered, otherwise the protruding part will be broken, crepe, discoloration, etc., so the paper should be neatly placed.
