在进行有关画册设计制作的时候,我们会发现在处理有关画册设计印刷的时候总是出现用纸带静电的现象,这是因为什么原因造成的呢?下面济南画册设计公司浅析印刷用纸带静电的原因。
In the design and production of the relevant album, we will find that when dealing with the album design and printing, there is always the phenomenon of electrostatic paper tape. What is the reason for this? The following Jinan album design company to analyze the printing paper with electrostatic reasons.
其实针对于纸张带静电与造纸有一定关系。一般情况下,出厂时原纸带电的较少,铜版纸带电的概率也不大。因印刷用纸(白板纸、卡纸等)及铜版纸是在原纸的基础上进行再加工,即使原纸已带电,在加工过程中也会。一般定量在80g/m2以下的纸张带静电偏多,但纸张上机印刷前就带有静电或印刷前静电并不明显,往往是经过压印后静电骤增。在胶印过程中由于有水,一般经过印刷后反而带静电者并不多见,对胶印来讲,静电主要产生在印刷之前。
In fact, for paper with static electricity and papermaking has a certain relationship. In general, when leaving the factory, the base paper is charged less, and the probability of charged coated paper is not large. Because printing paper (white board paper, cardboard, etc.) and coated paper are reprocessed on the basis of the original paper, even if the base paper has been charged, it will be eliminated during the processing. Generally, the paper with weight less than 80g / m2 has more static electricity, but the paper has static electricity before printing, or the static electricity before printing is not obvious, which is often the sudden increase of static electricity after imprinting. In offset printing process due to water, generally after printing with static electricity is rare, for offset printing, static electricity is mainly produced before printing.
画册印刷介绍对于纸张带静电的主要原因是摩擦生电。不少物体带电都是由摩擦引起的,造纸时纸张与压光机的摩擦,印刷时纸张与橡皮滚筒、压印滚筒之间的摩擦,都是产生静电的重要因素。各种不同物质的原子核对电子的束缚力是不一样的,或者说对电子有不同的亲疏特性。当两种不同的物质密切接触时,疏电子一方由于对电子的束缚力较弱,一些电子就会穿过交界面附着到亲电子一方的表面。这种电子转移的结果,会在交界面上形成一个双电层。这时如果两种物质迅速分离,疏电子一方由于失去一些电子而带正电,亲电子一方由于得到一些电子而带负电。这就是摩擦生电的实质。
The main reason for the paper static electricity is friction electricity. Many objects are electrified by friction. Friction between paper and calender in paper making, friction between paper and rubber roller and embossing roller during printing are important factors for electrostatic generation. The binding force of atoms in different substances is different, or they have different affinity to electrons. When two different substances are in close contact, some electrons will pass through the interface and adhere to the surface of the electron loving side due to the weak binding force of the electron sparing party. As a result of this electron transfer, a double layer is formed at the interface. In this case, if the two substances are separated rapidly, the one with the sparse electrons is positively charged because of the loss of some electrons, and the one with the electron affinity is negatively charged due to the acquisition of some electrons. This is the essence of friction electricity.
有关印刷材料中的纸张、橡皮布、油墨、印版等对电子的亲疏特性各不相同,印刷过程中很大的压力使它们密切接触,又有很高的速度使它们迅速分离,完全具备摩擦生电的条件。因此印刷中出现成千上万伏的静电是可以理解的,尤其是有些纸张在印刷前就带有静电。纸张在制造过程中已产生静电,来不及逸散就被包装起来发送到印刷厂时,仍然有些静电被保留下来,这也是印刷前纸张带电的原因。使用这些纸张时,要结合生产实际情况,采取不同的办法其所带静电。
The paper, blanket, ink, plate and so on in the printing materials have different affinity and affinity to the electron. During the printing process, they are in close contact with each other under great pressure, and they are separated rapidly at a high speed, which fully meets the conditions of friction electricity generation. Therefore, it is understandable that there are tens of thousands of volts of static electricity in printing, especially some paper with static electricity before printing. The paper has generated static electricity in the manufacturing process. It is packaged before it can escape and sent to the printing plant. When it is sent to the printing plant, some static electricity is still retained, which is the reason why the paper is charged before printing. When using these papers, we should take different measures to eliminate the static electricity in combination with the actual production situation.
