印刷过程中产生静电的主要因素!

  静电的主要原因是摩擦。当两种固体材料接触并迅速离开时,其中一种具有更强的吸附电子的能力,从而使电子转移到材料表面。获得的电子表面带负电荷,而另一个由于失去电子表面而带正电荷。

  The main cause of static electricity is friction. When two solid materials come into contact and leave quickly, one of them has a stronger ability to absorb electrons, thus transferring electrons to the surface of the material. The obtained electron surface is negatively charged, while the other one is positively charged due to the loss of the electron surface.

  产生静电的主要因素:

  The main factors causing static electricity are:

  1. 材料性能包括材料的内部化学成分、材料的内部结构、应力应变的力学特性、材料的形状和电导率等。

  1. Material properties include internal chemical composition, internal structure, mechanical properties of stress and strain, shape and conductivity of materials.

  材料的导电性对静电有双重影响。首先,如果材料是导体,电荷可以在其表面自由移动,并且电荷均匀地分布在其表面,而不是停留在产生电荷的地方。这种电荷在表面上的分布只造成低压。与导电材料的任何部分接触,电荷立即转移到地面。绝缘材料不同于导体,如大多数基材材料如纸张、塑料薄膜,产生的静电会形成较高的电压,不能通过接地消除。

  The conductivity of materials has dual effects on static electricity. First, if the material is a conductor, the charge can move freely on its surface, and the charge is evenly distributed on its surface, rather than staying where the charge is generated. The distribution of this charge on the surface only causes low pressure. In contact with any part of the conductive material, the charge is immediately transferred to the ground. Insulating materials are different from conductors, such as most base materials such as paper and plastic film. The static electricity generated will form a higher voltage, which can not be eliminated by grounding.

  2. 环境条件包括接触物(材料)周围气体的组成、压力、温度和湿度。

  2. Environmental conditions include the composition, pressure, temperature and humidity of the gases around the contacts (materials).

  3.机械效应包括两种材料之间的接触类型、接触时间、接触面积、分离速度和材料受力的性质。一般来说,两种材料接触得越近或分离得越快,静电电荷就越大。

  3. Mechanical effects include contact type, contact time, contact area, separation speed and mechanical properties of materials. Generally speaking, the closer the two materials contact or separate, the greater the electrostatic charge.

  4. 不同材料之间的摩擦会产生不同极性的静电。不同的材料有不同的静电强度

  4. Friction between different materials will produce different polarities of static electricity. Different materials have different electrostatic strengths

  高质量的冲压冲压质量的保证,常见的冲压生产版本的是相对简单的,主要是使用电子雕刻制版过程和照相腐蚀制版过程,现在包装制造商使用冲压工艺比较复杂,属于三维冲压的范畴。

  High quality stamping quality assurance, the common stamping production version is relatively simple, mainly using electronic engraving plate-making process and photo etching plate-making process, packaging manufacturers now use stamping process is more complex, belongs to the category of three-dimensional stamping.

  温度、压力和速度是三维冲压技术的三个要素,只有控制三者之间的关系,才能控制冲压的质量。烫印速度快,加热时间短,烫印温度下降快,导致温度偏低,会影响烫印牢度;烫印速度慢,加热时间长,烫印温度下降慢,烫印牢度好,但如果控制不好会导致烫印温度过高。因此,适当的冲压速度是为了获得高质量的冲压效果。立体烫金除了电化铝箔的要求转移到印刷品的表面,与巨大的压力,还烫印压力压花模式的一部分,所以压力大于普通烫金,这需要更好的烫金箔的强度,以承受强大的压力。

  Temperature, pressure and speed are the three elements of three-dimensional stamping technology. Only by controlling the relationship among them can the quality of stamping be controlled. The hot stamping speed is fast, the heating time is short, and the hot stamping temperature drops quickly, which leads to low temperature, which will affect the hot stamping fastness. The hot stamping speed is slow, the heating time is long, the hot stamping temperature drops slowly, and the hot stamping fastness is good, but if not well controlled, the hot stamping temperature will be too high. Therefore, the proper stamping speed is to obtain high quality stamping effect. In addition to the requirement of electrochemical aluminium foil transferring to the surface of printed matter, and the huge pressure, but also stamping pressure embossing mode part, so the pressure is greater than ordinary stamping, which requires better stamping foil strength to withstand strong pressure.
