在進行有關畫冊設計制作的時候,我們會發現在處理有關畫冊設計印刷的時候總是出現用紙帶靜電的現象,這是因為什么原因造成的呢?下面濟南畫冊設計公司淺析印刷用紙帶靜電的原因。
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.
其實針對于紙張帶靜電與造紙有一定關系。一般情況下,出廠時原紙帶電的較少,銅版紙帶電的概率也不大。因印刷用紙(白板紙、卡紙等)及銅版紙是在原紙的基礎上進行再加工,即使原紙已帶電,在加工過程中也會。一般定量在80g/m2以下的紙張帶靜電偏多,但紙張上機印刷前就帶有靜電或印刷前靜電并不明顯,往往是經過壓印后靜電驟增。在膠印過程中由于有水,一般經過印刷后反而帶靜電者并不多見,對膠印來講,靜電主要產生在印刷之前。
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.
畫冊印刷介紹對于紙張帶靜電的主要原因是摩擦生電。不少物體帶電都是由摩擦引起的,造紙時紙張與壓光機的摩擦,印刷時紙張與橡皮滾筒、壓印滾筒之間的摩擦,都是產生靜電的重要因素。各種不同物質的原子核對電子的束縛力是不一樣的,或者說對電子有不同的親疏特性。當兩種不同的物質密切接觸時,疏電子一方由于對電子的束縛力較弱,一些電子就會穿過交界面附著到親電子一方的表面。這種電子轉移的結果,會在交界面上形成一個雙電層。這時如果兩種物質迅速分離,疏電子一方由于失去一些電子而帶正電,親電子一方由于得到一些電子而帶負電。這就是摩擦生電的實質。
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.
有關印刷材料中的紙張、橡皮布、油墨、印版等對電子的親疏特性各不相同,印刷過程中很大的壓力使它們密切接觸,又有很高的速度使它們迅速分離,完全具備摩擦生電的條件。因此印刷中出現成千上萬伏的靜電是可以理解的,尤其是有些紙張在印刷前就帶有靜電。紙張在制造過程中已產生靜電,來不及逸散就被包裝起來發送到印刷廠時,仍然有些靜電被保留下來,這也是印刷前紙張帶電的原因。使用這些紙張時,要結合生產實際情況,采取不同的辦法其所帶靜電。
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.
