Introduction of Vacuum flap valve of vacuum coating machine
The high-vacuum pneumatic flap valve is a kind of compressed air as the power to change the direction of piston movement, thereby driving the valve plate to start, realizing the conduction and cut-off of the gas in the vacuum system or pipeline. This type of valve structure is relatively simple, opens and closes quickly, and can be adapted to automatic control systems. It is now used in electronics, food, metallurgy, biomedicine, atomic energy, aerospace, chemical and other medium and large equipment (such as vacuum coating equipment, vacuum furnace, vacuum Freeze drying equipment) and other wide applications.
Vacuum coating technology is a novel material synthesis and processing technology, and it is an important part of the field of surface engineering technology.
Vacuum coating technology is the use of physical and chemical means to coat the solid surface with a layer of special performance coating, so that the solid surface has wear resistance, high temperature resistance, corrosion resistance, oxidation resistance, radiation protection, conductivity, magnetic conductivity, insulation and decoration And many other superior properties that are superior to the solid materials themselves, to achieve the effects of improving product quality, extending product life, saving energy and obtaining significant technical and economic benefits. Therefore, vacuum coating technology is known as one of the most promising and important technologies, and has shown attractive market prospects in the development of high-tech industrialization.
It is mainly used for coating under high vacuum, and it is used in many industries, such as automobile, medical, transportation, machinery, service and other industries, and it is also a coating equipment that is very close to people's lives.
Vacuum coating equipment is an important part of the coating industry. Without advanced and efficient coating machines, there would be no modern coating industry.
Vacuum coating will encounter film drop. What is the reason for this situation and how to solve these problems?
1. Surface cleanliness
The surface cleanliness of the product is not enough, you can consider argon amplification and longer time when cleaning the ion source.
2, problems in the cleaning process
The cleaning is not in place before plating, or the cleaning fluid is replaced.
3. The problem of craftsmanship
Whether the process parameters have changed, make appropriate adjustments on the coating time and current.
4. The problem with the target material
Whether the titanium target is poisoned, check and replace it.
5. Whether the vacuum chamber is leaking
Perform a leak detection.
6. Product surface oxidation
There are many reasons for oxidation, so you can judge and deal with it yourself.
