Silica fume is a by-product recovered in the process of non-ferrous metal processing, its particles are very fine, the relative density is very small, which causes two phenomena in the specific application of the process: one is the relative density of a small weight, the delivery cost is very high; the second is in the application of the process, in view of silica fume has specificity, it is very easy to spill, easy to produce secondary environmental pollution. Silica fume encryption process is a very good solution to these two phenomena. heavily density silica fume, heavy encrypted silica ash, heavy encrypted silica powder Chengdu Rongjian Engineering Materials Co.Ltd , https://www.rjsilicafume.com
Germany Lai Po vacuum pump oil selection guide
In order to ensure Leybold vacuum pump oil to obtain the normal operation of equipment, the correct choice of vacuum lubricants is crucial, should be given great importance. Lippo vacuum pump oil physical and chemical indicators Vacuum vacuum pump is generally 10-4 The maximum requirements can be 10-8 mm Hg or more, so the quality of vacuum pump oil should have very low vapor pressure. That is to say the evaporation of the oil is very small, the number of paraffin-based narrow distillate oil is ideal. Because the vacuum pump is easy to inhale moisture so the oil should have excellent water separation. For suction and impurity-contaminated vacuum pumps, lubricants should also contain clean, floating additives to prevent sludge, carbon deposits and dirt from forming on the lubrication area of ​​the vacuum pump. Ideal Lubrizol vacuum pump oil should have a high viscosity index, low saturated vapor pressure, good oil water separation and oxidation stability, good pumping rate and ultimate vacuum. Vacuum pump oil physical and chemical properties of the test items: kinematic viscosity (40 ℃), viscosity index, flash point, anti-emulsification, anti-foam, oxidation stability, saturated vapor pressure, ultimate pressure and limit pressure. According to the quality level of the physical and chemical properties of the testing project set the quality indicators can be found in the petroleum products industry standard SH / T0528-92.
