    • The plastic film electrostatic adsorption apparatus and electrostatic adsorption method of the present invention disclose a plastic film electrostatic adsorption apparatus comprising an electrostatic adsorption electrode, an insulated dielectric layer that covers the electrostatic adsorption electrode and has a center line average roughness of the adsorption surface on which the plastic film is placed of 0.5 nullm or less, and a power supply electrode that applies a voltage to the electrostatic adsorption electrode. According to this plastic film electrostatic adsorption apparatus and electrostatic adsorption method, surface treatment can be performed even in a vacuum without requiring tedious work such as application or removal of adhesive. In addition, even if the plastic film expands and deforms due to heat treatment and plasma treatment performed during surface treatment, there is no occurrence of wrinkling, deformation of separation in the plastic film due to the difference in thermal expansion between the electrostatic adsorption surface and plastic film.
    • 本发明的塑料膜静电吸附装置和静电吸附方法公开了一种塑料膜静电吸附装置,其包括静电吸附电极,覆盖静电吸附电极的绝缘电介质层,并且其吸附表面的中心线平均粗糙度在 放置0.5μm以下的塑料膜和向静电吸附电极施加电压的电源电极。 根据这种塑料膜静电吸附装置和静电吸附方法,即使在真空中也可以进行表面处理,而不需要诸如施加或去除粘合剂的繁琐的工作。 此外,即使由于表面处理中进行的热处理和等离子体处理而导致的塑料膜膨胀变形,也不会由于静电吸附面和静电吸附面之间的热膨胀差而在塑料膜中产生褶皱,分离变形 塑料薄膜。

    • The invention describes a device and a process for producing extrusion-coated laminates. The extrusion device contains an extruder nozzle with nozzle lip, a cooling roller and a contact roller, wherein the cooling roller and the contact roller form a roller gap and the extruder nozzle is directed towards the roller gap. A melt of thermoplastic plastics, which enters the roller gap while forming a coating film and is joined to a substrate film in the roller gap, emerges from the nozzle lip. A device for improving the adhesion of the coating film to the substrate is thus disposed in the region between the extruder nozzle and the roller gap at a slight distance from the film. The device is a corona treatment station which has a discharge electrode at high voltage and an electrically earthed counter-electrode on only one side of the coating film.
    • 本发明描述了一种用于生产挤出涂覆的层压板的装置和方法。 挤出装置包括具有喷嘴唇缘的挤出机喷嘴,冷却辊和接触辊,其中冷却辊和接触辊形成辊间隙,挤出机喷嘴指向辊间隙。 在形成涂膜的同时进入辊间隙并与辊间隙中的基底膜接合的热塑性塑料的熔体从喷嘴唇露出。 因此,用于提高涂膜对基材的粘附性的装置因此在与胶片稍微距离处设置在挤出机喷嘴和辊间隙之间的区域中。 该装置是电晕处理站,其具有高电压放电电极,仅在涂膜一侧具有接地的对电极。
