Roots pump oil Roots pump Roots pump oil not only as a vacuum medium, but also on the mechanical friction point lubrication, cooling and sealing effect.
The main performance requirements:
Extremely low vapor pressure
This is the most important performance of Roots pump oil, because Roots pump requires a high degree of vacuum, the general paraffin-based narrow-cut lubricant, the proliferation of Roots pump, you can also use very low vapor pressure silicone oil or other synthetic oil .
2. Appropriate viscosity and good viscosity-temperature properties
Roots pump chamber volume changes continuously evolved to form the role of exhaust, lubricating oil should have the appropriate viscosity and viscosity-temperature characteristics.
3. Good thermal oxidation stability
Roots pumps continue to develop at a high speed. Due to the high friction between the vanes and the pump body, the oil temperature is increased. The oil products are easily oxidized and decomposed. In particular, the diffusion pumps often work under very high temperature conditions, High, reducing the degree of vacuum, therefore requiring Roots pump oil has good thermal oxidation stability.
4. Good corrosion resistance and anti-emulsification
ZJ Roots pump inhaled if it is corrosive gas, will react with the oil, corrosion pump parts; inhaled air often contain water vapor condensate water, causing Roots pump oil emulsification and corrosion of the metal, it is required to have good Anti-corrosion and anti-emulsification.
5 high flash point
The main requirements of the Roots pump does not carry light components, so as not to affect the saturated vapor pressure of oil.
6. Lower limit pressure
Extreme pressure is an important use of Roots pump oil performance indicators to understand the minimum vacuum limit pressure Roots pump ultimate pressure
Melamine is an important chemical raw material, which is mainly used for condensation with aldehyde to produce melamine and formaldehyde Resin. This resin is not easy to ignite, water resistant, heat resistant, aging resistant, arc resistant, chemical corrosion resistant, has good insulation performance and mechanical strength, and is widely used in wood, plastic, paint, paper, textile, leather, electrical, pharmaceutical and other industries; It can also be used as glue, flame retardant, formaldehyde cleaner, etc; In some Asian countries, it is also used to make fertilizer.
Its main uses are as follows:
(1) Decorative panel: It can be made into fireproof, anti-seismic and heat-resistant laminated plates, bright color, solid and heat-resistant decorative plates, and used as the veneers of aircraft, ships and furniture, as well as fireproof, anti-seismic and heat-resistant house decoration materials.
(2) Paint: after etherification with butanol and methanol, it can be used as the binding agent of advanced thermosetting coatings and solid powder coatings, and can be used to make metal coatings and high-grade amino resin decorative coatings for vehicles and electrical appliances.
(3) Molded powder: melamine plastic can be made through mixing, granulation and other processes. It is non-toxic, antifouling, and can still maintain good electrical performance when wet. It can be made into white, batter-resistant household utensils, sanitary ware, imitation porcelain tableware, electrical equipment and other advanced insulating materials.
(4) Paper: After etherification with ether, it can be used as a paper treatment agent to produce wrinkle-resistant, shrink-resistant, non-perishable banknotes, military maps and other high-grade paper.
(5) When mixed with other raw materials, melamine formaldehyde resin can also produce fabric finishing agent, leather tanning agent, polishing agent and water-resistant agent, rubber adhesive, combustion aid, high-efficiency cement water-reducing agent, steel desalting agent, etc.
