低温天气对uedbet官网进不去纸张的影响!

uedbet官网进不去生产中,纸张是对环境温湿度要求极高的耗材之一,纸张为多孔物质,其基本结构是由植物纤维和辅料组成,具有较强的亲水性,若环境温湿度得不到良好控制,会导致纸张变形,影响正常uedbet官网进不去。因此,保持适宜的环境温湿度是提高纸张印品品质和提高生产效率的关键。
In printing production, paper is one of the consumables which have high requirements for environmental temperature and humidity. Paper is a porous material. Its basic structure is composed of plant fibers and accessories, which has strong hydrophilicity. If the environmental temperature and humidity are not well controlled, it will lead to paper deformation and affect the normal printing. Therefore, to maintain the appropriate environment temperature and humidity is the key to improve the quality of paper printing and production efficiency.
普通纸张对于环境温度的要求不那么明显,但当环境温度低于10℃时,普通纸张就会变得很“脆”,uedbet官网进不去过程中墨层在其表面的附着力就会下降,容易造成脱墨现象。
The requirement of ambient temperature for ordinary paper is not so obvious, but when the ambient temperature is lower than 10 ℃, ordinary paper will become very "brittle", and the adhesion of ink layer on its surface will decrease in the printing process, which is easy to cause deinking phenomenon.
金银卡类纸张通常是以铜版纸、白板纸、白卡纸等为基材,然后再复合PET膜或铝箔等材料生产而成。金银卡类纸张对环境温度的要求更高一些,这是因为金属和塑料材质对于温度的变化都非常敏感.
Gold and silver card paper is usually made of coated paper, white board paper, white card paper, etc., and then compounded with PET film or aluminum foil. Gold and silver card paper requires higher ambient temperature, because metal and plastic materials are very sensitive to temperature changes
当环境温度低于10℃时,将大大影响金银卡类纸张适性,当金银卡类纸张的储存环境温度在0℃左右时,从纸库运送到uedbet官网进不去车间后,其表面就会因温差而出现大量水汽,影响正常uedbet官网进不去,会导致废品出现。如果遇到上述问题,而且交货期紧张,工作人员可先打开UV灯管让纸张空跑一遍,使其温度与环境温度相平衡后再正式uedbet官网进不去。
When the ambient temperature is lower than 10 ℃, the suitability of gold and silver card paper will be greatly affected. When the ambient temperature of gold and silver card paper is about 0 ℃, when it is transported from the paper warehouse to the printing workshop, a large amount of water vapor will appear on its surface due to the temperature difference, which will affect the normal printing and lead to waste products. If you encounter the above problems, and the delivery time is tight, the staff can first turn on the UV lamp to let the paper run again, so that its temperature is balanced with the ambient temperature before formal printing.
此外,低温干燥,相对湿度低,纸张与空气进行水分交换,纸张变干燥,变翘,收缩,会造成套印不好。
In addition, low temperature drying, low relative humidity, paper and air moisture exchange, paper drying, warping, shrinkage, will cause poor overprint.
