Ho hanyetsa kutu ea lisebelisoa tse tloaelehileng bakeng sa li-valve - NBR
2021-06-15
NBR e fumanoa ka emulsion polymerization ea butadiene le acrylonitrile, 'me NBR e hlahisoa haholo ke mocheso o tlaase oa emulsion polymerization. Ho hanyetsa oli e ntle haholo, khanyetso e phahameng ea ho roala, ho hanyetsa mocheso o motle, ho khomarela ka matla. Mefokolo ea eona ke ho hanyetsa mocheso o tlase, ho hanyetsa ozone, ts'ebetso e fokolang ea ho kenya letsoho le elasticity e tlase hanyane. NBR e sebelisoa haholo ho etsa lihlahisoa tsa rabara tse hanyetsanang le oli. NBR ke mofuta oa rabara ea maiketsetso e entsoeng ka butadiene le acrylonitrile. Ke rabara ea maiketsetso e nang le khanyetso e ntle ea oli (haholo-holo oli ea alkane) le ho hanyetsa botsofali. Acrylonitrile content (%) ho NBR ke 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30 le 18 ~ 24. Lintho tse phahameng tsa acrylonitrile, li molemo ho hanyetsa oli, empa li fokotsa ho hanyetsa serame. Ho phaella moo, e na le ho thibela metsi hantle, ho tiisa moea le ho khomarela hantle. E sebelisoa haholo ho etsa lihlahisoa tse fapaneng tsa rabara tse hanyetsanang le oli, li-gaskets tse fapaneng tse hanyetsanang le oli, li-gaskets, matsoho, liphutheloana tse feto-fetohang, li-hose tse feto-fetohang, liphahlo tsa khatiso le ho daea, lisebelisoa tsa rabara tsa cable, joalo-joalo. petroleum, ho kopitsa le liindasteri tse ling.
