1. Grease: In the process of polysilicon production, oil molecules are very harmful to polysilicon. It has been proved that a few ppm of oil content in the entire process system may cause the polysilicon reaction rate to slow down, the yield to decrease, and even the silicon reaction to stop. Therefore, the degreasing process of polysilicon equipment is particularly important.
2. Moisture: The water contains a large amount of chloride ions, which are very sensitive to the reaction of polycrystalline silicon. Equipment and system drying processes are critical.
3. Chloride ion residue: Chloride ions remaining on the surface of water and other solutions have a great influence on polysilicon. Therefore, it is very important to carry out a pure water rinsing process on the equipment after cleaning.
4, oxides, dust and other impurities: the presence of other dirt, the impact on the production of polysilicon is also very large. Therefore, it is necessary to use the pickling process to clean other dirt during the equipment cleaning process.
PVD Color Nano sink
PVD is an innovative technology that can deposit very fine and thin metal films on products. Applied to stainless steel sinks, this technology ensures the durability and longevity of the product's color and helps maintain its beauty. Nano-coating makes the sink antibacterial, waterproof and oil resistant.
Advanced PVD color.
Customize black, gold, rose gold and bronze color. Satisfy different style kitchen demands.
Nowadays, the NANO sinks are more and more popular. Lots of companies are looking for this kind of sinks. NANO finish can make the sink cleaning easier, because the surface is bright so it will be hard to stain oil. Moreover, NANO sinks can improve the corrosion resistant and scratch resistant.
