Fumed Silica it is a kind of high
purity white colloidal powder.Fumed Silica divide into Hydrophilic
and hydrophobic different technologies products. Quanxu Technology Fumed Silica
basically properties are white, non-toxic, tasteless, amorphous and inorganic. We
have strictly control of particle size, surface area, and the products have
more activate surface. With its unique features of particle size, high purity,
aggregated structure and low bulk density, it is widely used in fine chemical
such as Silicone Sealant, Rubber, Paints, Unsaturated Polyester, Cosmetics, Agriculture,
and Medicine etc

Low temperature control valve installation skills
Low temperature control valve installation skills: 1, check the machine parts are defective and loose. For the use of harmful human health media, must be intensity, sealing, leakage and accuracy testing. 2, before the installation of pipes and valves for cleaning, remove impurities and grease. In particular, oil-free occasions, users can make specific cleanliness requirements. Selection of lubricants, must consider the taboo of working medium, to avoid accidents. 3, the valve body and pipe flange connection, pay attention to the coaxiality. Use a wraparound connection between the connection flange on the bonnet and the cold box whenever possible. Import pump valve 4, the installation site should consider the safety of personnel and equipment, both for operation, but also conducive to disassembly and maintenance. 5, the valve should be upright, mounted vertically on the horizontal pipe, the last resort can be tilted installation, the valve from the vertical or larger vibration occasions, must be fixed with a support frame. 6, the media flow direction should be consistent with the arrow on the valve body. Air flow should be dry, no oil. Valves should be between the ambient temperature -30 ~ 60 ℃ role. 7, in order to make the automatic control system failure or repair the valve can still be continuous production, should be set up bypass. Bypass valve flow characteristics and stroke should be consistent with the original valve selection. More keyword search: Regulating valve
