真空镀膜机知识知多少?虽然真空行业现在很热门,在市场上使用的范围也是非常广泛的,但是对于很多人对真空镀膜机,只知道真空镀膜机是用来镀物件的表面膜层,稍深入点的知识,就不太清楚了。今天海盐鑫中岳小编为大家整理了一些关于真空镀膜机表面涂层材料介绍,及镀膜机的应用和注意事项,希望能够帮助到大家。

       真空镀膜机表面处理涂层材料分为三种:

    (1)渗透型表面处理涂料:渗透型的表面处理涂料基本原理是采用渗透性强的树脂为基,配合极性溶剂、渗透剂使得涂料具备良好的性能,并增强涂层的附着力。

    (2)稳定型表面处理涂料:稳定型的表面处理涂料基本原理主要是靠涂料中活性原料与锈层中活泼的成分起反应,使用比较多的活性原料有氧化锌、磷酸锌、铬酸锌、铬酸钡、有机氮碱铬酸盐,铬酸钙、三聚磷酸铝、有的配方还添加亚硝酸钠,也有认为加入铬酸锶是必要的。

    (3)转化型表面处理涂料:转化型表面处理涂料也叫反应型带锈涂料,这类涂料不含成膜物质,也因为这样所以还需要另外加底漆配合,如果含有成膜物质则称之为锈蚀转化底漆。

 

  真空镀膜机注意事项

    (1)设备接地必须可靠,并经常检查接地装置导电作用。

    (2)扩散泵和油增压泵加热前必须接通冷却水,泵停止工作,但泵内示冷却至80摄氏度以下时,不得切断冷却水,以防止泵芯烧毁。

    (3)扩散泵和油增压泵在加热情况下,切勿与大气接触,以免泵油氧化。

 

   真空镀膜机的应用

    (1)食品工业的软包装:饼干及烘焙类产品,糖果,咖啡,茶叶,巧克力块,汤料,高阻隔膜;

    (2)装饰:礼品包装,商标,热烫印箔,全息等;

    (3)多种技术和日用品:纺织工业的镀铝丝线,建筑和汽车业的防晒膜,安全及防伪(全息),电容膜,静电屏蔽(电缆及电子)

How much do you know about vacuum coating machine? Although the vacuum industry is very popular now, it is widely used in the market. But for many people, the vacuum coating machine only knows that the vacuum coating machine is used to deposit the surface film layer of the object. Today, Haiyan xinzhongyue Co., Ltd. arranged for you some introductions on the surface coating materials of vacuum coater, as well as the application and precautions of coater, hoping to help you.

There are three kinds of coating materials for surface treatment of vacuum coater:

(1) Penetrating surface treatment coating: the basic principle of penetrating surface treatment coating is to use the resin with strong permeability as the base, cooperate with polar solvent and penetrant to make the coating have good performance and enhance the adhesion of the coating.

(2) Stable surface treatment coating: the basic principle of stable surface treatment coating mainly depends on the reaction between the active raw materials in the coating and the active components in the rust layer. More active raw materials are used, such as zinc oxide, zinc phosphate, zinc chromate, barium chromate, organic nitrogen alkali chromate, calcium chromate, aluminum tripolyphosphate, some formulas are also added with sodium nitrite, others think that strontium chromate is added It is necessary.

(3) Conversion type surface treatment coating: conversion type surface treatment coating is also called reaction type rust coating. This kind of coating does not contain film-forming substances, and because of this, it also needs to add another primer. If it contains film-forming substances, it is called rust conversion primer.

&Precautions for vacuum coating machine

(1) Equipment grounding must be reliable, and the conductive function of grounding device shall be checked frequently。

(2) Before heating the diffusion pump and oil booster pump, the cooling water must be connected and the pump stops working。 However, when the temperature inside the pump is lower than 80 ℃, the cooling water shall not be cut off to prevent the pump core from burning。

(3) When the diffusion pump and oil booster pump are heated, do not contact with the atmosphere to avoid oxidation of pump oil。

&Application of emsp; vacuum coating machine

(1) Soft packaging of food industry: biscuits and baked goods, candy, coffee, tea, chocolate block, soup, high resistance diaphragm;

(2) Decoration: gift packaging, trademark, hot stamping foil, holography, etc;

(3) Various technologies and daily necessities: aluminized wire in textile industry, sun protection film in construction and automobile industry, safety and anti-counterfeiting (holography), capacitance film, electrostatic shielding (cable and Electronics)
