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)
