The future development of coating industry must be vacuum coating

there are two main types of professional coating methods,one is chemical deposition (CVD), one is physical climate accumulation, also called vacuum deposition (PVD).

Chemical coating is rich in a membrane element of gaseous reaction agent or liquid reaction required for other gas introducing echo chamber, in the process of chemical reaction to generate film substrate appearance attack. In the process of chemical film, simple solution pollution, if the coating appearance more impurities, owe better plating.

Chemical coating demand response temperature is very high, usually to control at 1000 ℃ or more, but many matrix data cannot be influenced by the high temperature, timely and cemented carbide, although can endured high temperature, because of the high temperature in chemical coating manufacturing environment will also constitute a coarse grains,which cause the brittle phase, function deterioration. If on the carbide TiN plating, diffusion of carbon will attack response and solution decarburized layer, the layer patience is poor, low flexural strength, constitute a taking shorten tool use.

Vacuum coating machine dispose of chemical coating attack in a series of questions excellently. Vacuum coating is under the condition of vacuum, choose low voltage, high current arc discharge skills, using gas discharge ability, use other discharge is the transpiration and restore the transpiration of target material and gas ionization, all using the accelerating effect of electric field, the accumulation and reaction products made by transpiration material on the workpiece.

All coating materials are in a vacuum environment after plasma accumulation in the appearance of workpiece, the disposal of the chemical plating solution of pollution question, not toxic or pollutants, plating film hardness higher, good wear resistance and corrosion resistance, more safe. Disposal of vacuum coating technology can control the temperature below 150 ℃ ~ 500 ℃, suitable for a variety of substrate materials, preparation of colorful coating, plating system of carbide cutting tools can make its full progress 2 ~ 10 times.

Lon vacuum coating technology characteristics and uses

Lon vacuum coating technology characteristics and uses:

Vacuum ion titanium PVD technology is applied.Metal and various gases (argon, nitrogen, oxygen and acetylene gas, etc.) occur in a particular environment (pressure, temperature, electromagnetic field, etc.) the combined effect of plasma formation, after accelerated plasma flock to the workpiece surface to be plated, is formed solid film. The fine titanium coating evenly, with strong, high hardness, corrosion resistant, has good conductivity and self-lubricating properties, while the color and variety, it is not only to improve the material titanium vacuum performance of a powerful tool in the decoration the same is to enhance the quality, improve the best choice for value-added.

PVD coating technology of vacuum coating machine

PVD coating technology of vacuum coating machine

Whenever a new technology appears meant a reshuffle of the industry, but also tend to promote the adjustment of its upstream and downstream industries, indeed affect the whole body. Vacuum coating functions change from even a short time nearly the end of the traditional coating methods, is a historical necessity, the result is the joint efforts of various industry experts.
Vacuum coating technology division multiple classes, but are built in a vacuum coating, PVD (Physical Vapor Deposition) technology coating must have a vacuum chamber, to avoid evaporation out of the reaction material and the air, which is a physical vapor deposition coating technology.
We all know that in the vacuum coating technology, the matrix material from a solid to a gaseous state to adhere to the workpiece to form a thin film layer, PVD coating coating methods because they do not use chemical coating thus environmental pollution, which is respected by PVD technology factors one.

Vacuum coating machines and sanitary ware surface treatment

Vacuum coating machines and sanitary ware surface treatment

Vacuum coating machine manufacturers: sanitary ware products most commonly used methods of surface treatment of sanitary ware products after casting or machining still need to go through polished or finished and then after the addition of various surface treatments and for a while intact.
So, our sanitary ware products which most often surface approach adopted? For different pieces of sanitary ware in the end we need to adopt a surface approach and what is the most appropriate way of it? It requires a combination of products for different substrate materials, different customer requirements, different grades of positioning, different surface treatment process under production costs, among other factors, to make the right choice.
Vacuum coating machine manufacturers: Surface treatment approach sanitary ware products industry, the most commonly used generally have the following:
1, the painting process: This is one of the most well-known approach, low cost, simple treatment process, it is by means of air pressure through the gun, uniform and finely dispersed into droplets, are applied to the surface of sanitary ware pieces a method. It can be divided into air spray, airless spray, and electrostatic spray painting and other methods. Paint, usually there is a certain toxicity, have a certain influence on the body, different brands of paint toxicity due to the different ingredients are different. Use should pay special attention to safety and to avoid inhalation and skin contact.
2, the electroplating process: electroplating process is the use of electrochemical principles to sanitary ware products covered with a layer of metal approach. In addition to copper, iron, zinc alloy, aluminum and other conductive materials, ABS plastic sanitary ware pieces can also approach to the electroplating process. It includes water and vacuum plating processing electroplating process. Generally we are talking about is the water electroplating process plating, vacuum plating and coating called.
3, the electrophoresis process: that electrophoretic paint, electrophoretic coating electrophoresis is the Yin and Yang, the role of the applied voltage, charged ions paint sanitary ware products are moved to the surface, and the basic role of the surface of the product arising from the formation of insoluble thereof, these substances which is deposited on the surface of the product.
4. Spray: plastic powder coating spray is on sanitary ware products in a surface approach. It is often said of electrostatic powder spray coating, which is the use of electrostatic generator to make plastic powder charged, adsorbed on the surface of our sanitary ware products, then baked at high temperatures, melting the powder on the surface of the adhesion of a product's surface approach.
