The role of various water purification filter elements. I. pp cotton filter element: 1> polypropylene fusion filter element is made of fiber with polypropylene resin as raw material, and is bonded by the winding of the fiber itself. The structure of the filter element is thick outer fiber, fine inner fiber, loose outer layer, and tight gradient diameter of the inner layer. The unique gradient deep filtration has formed the effect of stereo filter slag, which is characterized by high porosity, high interception rate, large amount of pollution, large flow and low pressure drop. 2> the pore size of PP melt blown filter element is dense and uniform, and the filtration efficiency is high. Because the particles will Bridge in the pores of the PP fusion filter element, the particles smaller than the pores can also be blocked, and the filtration efficiency is more than 98%. PP fusion filter element has high cleanliness and no pollution to water quality. Corrosion of chemical reagents such as acid and alkali and organ

Air conditioning system efficient filter leak detection method for pharmaceutical GMP factory building? It's best to test with smoke,It can be completely assured and convincing to use the dust ion counter,The general requirements of the State Bureau are in the 'clean room construction and acceptance code' GB50591-Two methods are described in 2010. one is the dust particle counter method and the other is the luminosity method.Because I was testing,Generally used in factory testing is the spectrometer method,More convenient,Fast.The detection effect is also more accurate.And the pharmaceutical factory I tested with the spectrometer passed their GMP!Detection with dust Ion Counter,There is also smoke detection,High efficiency filter test method, Sodium Flame method Sodium Flame originated in the United KingdomChina,Some European countries in the 20 th century 70 ~ Implemented in 1990s.The source of the test dust is sodium chloride salt spray.'Quantity' is the brightness of the hydrogen flame when it contains sal
