上海11选5 【真空镀膜机】真空镀膜机表面处理涂料介绍

上海11选5  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、

上海11选5  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。

上海11选5  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。

上海11选5  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;

上海11选5  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)

[vacuum coater] introduction of surface treatment coating for 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.

上海11选5   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. The active raw materials used are zinc oxide

上海11选5Zinc phosphate, zinc chromate, barium chromate, organic nitrogen base chromate, calcium chromate, aluminum tripolyphosphate, some formulas also add sodium nitrite, it is also considered that it is necessary to add strontium chromate.

   3. Conversion surface treatment coating

Precautions for vacuum coating machine

   1. The equipment must be grounded reliably, and the conductivity of the grounding device shall be checked frequently.

上海11选5   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 must not be cut off to prevent the pump core from burning.

   3. When heating diffusion pump and oil booster pump, do not contact with atmosphere to avoid oxidation of pump oil.

上海11选5Application of 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, sunscreen film in construction and automobile industry, safety and anti-counterfeiting (holography), capacitor film, electrostatic shielding (cable and Electronics)
