The reason why the glass coating of the vacuum coating machine will drop the film

What is the problem caused by the glass coating of the vacuum coating machine? Now let's learn this together.

The surface cleaning treatment of the parts of the evaporative vacuum coating machine is very necessary, because if it is affected by the external environment, the vacuum system cannot be used normally and the high vacuum degree cannot be achieved.

In addition, in the presence of impurities, the connection and tightness of the vacuum components are affected.

Contaminants and impurities are completely useless to vacuum. Multi-arc ion vacuum coating will divide them into solid impurities, gaseous impurities and liquid impurities according to the state of the impurities. They exist in the form of particles. From a chemical point of view, it can be either ionic or covalent, either organic or inorganic.

The exposed surface layer is most likely to be contaminated. There are many kinds of contaminated situations. At the beginning, it is generally formed by its own operation.

It should be noted that surface adsorption, chemical action, cleaning and drying processes, and machinery may produce stains during various operations to increase surface contaminants.

Paying attention to the maintenance and cleaning of the machine in the early stage can reduce a lot of troubles in the later stage and prevent the occurrence of various small conditions of the sputtering vacuum coating machine. It can improve work efficiency and the quality of the vacuum coating machine. The quality of the coating also plays a very important role.

It can maximize the improvement of the vacuum system wall and other machine parts can work stably under different conditions.
