diffusion pump oil for high vacuum and high speed pumping
704 Diffusion Pump Oil-Can produce vacuum of 10-5 to 10-8 torus (no trap type) and 10-10 to 10-11 torus (including trap type)
The diffusion pump oil is mainly used to meet the requirement of high - speed pumping and high vacuum degree of a large amount of gas or vapor in the production operation.
The 704 diffusion pump oil is a single component liquid. It can produce high vacuum pressure ranges from 10-6 to 10-8 torus (without catcher) and 10-10 to 10-11 (containing trap trap) under complex and harsh conditions. It can show good performance, even when exposed to air at working temperature, it can also achieve rapid pumping.
Short adjustment run time-One-component silicone oil takes much less time to reach maximum capacity with multicomponent oil.
Fast evacuation-Compared with those that use motor oil for diffuser pumps. The diffuser pump using silicon oil can operate under the condition that the front stage pressure is higher than 20% to 300%. If you want to obtain higher gas flux at the high pressure end of the diffuser pump's working range. Heat input can increase 20% to 30%.
Minimal reflux-The vapor pressure of the single component silicon oil is very low, so it is not necessary for many traps or existing traps to be cooled.
Longer service life-The thermal and chemical stability of silicone oil ensures long term operation without loss or pollution.
Cleaner systems and less maintenance-At the baffle temperature, the low vapor pressure of the silicone oil leads to low mobility. The nozzle and boiler surface are kept clean. Under the operating conditions, there is almost no decomposition of the silicone oil.
Faster cycles, lower downtime, fewer oil replacements-The recovery rate of silicon oil after exposure to air at operating temperature is several times that of the oil. Since silicon oil has excellent antioxidant and anti hydrolysis properties, the vacuum can be removed without cooling the diffusion pump, so the cycle time is greatly shortened.
Scope of application:
Electronics industry-Producing a vacuum in a TV picture tube and a cathode-ray tube; Vacuum in power and microwave tubes; Vapor deposition of thin films by sputtering or evaporation in equipment and microcircuits
Metallurgical Industry-Electron beam application; High vacuum melting furnace; Melting, degassing and sintering of refractory metals; Thick film deposition
Vacuum coating-Aluminizing treatment of TV picture tube; Optical coating; For exotic items and auto parts
Decorative coating-Study on the coating of architectural glass, plastic sheet and sheet metal; Ultrahigh vacuum and ultraclean vacuum for film, surface emission coefficient, lubrication and metal fatigue research
The product shall be stored at 25°C (77°F) or 25°C (77°F) and original unsealed container. The shelf life of the product should be 60 months from the date of production.
Considering the rare and undefined conditions at 21 degrees C (70 degree F), 704 diffusion pump oil will crystallize. Therefore, 702 diffusion pump oil is recommended as a priority for sealing sensors in low temperature environment
