Joalo ka ha re tseba, har'a lipoleiti tsa mochini oa mocheso oa poleiti, poleiti ea titanium e ikhethile ka lebaka la ho hanyetsa ha eona ho hoholo ha kutu.'Me ha ho khethoa gasket, viton gasket e tumme ka ho hanyetsa acid le alkali le lik'hemik'hale tse ling.Joale na li ka sebelisoa hammoho ho ntlafatsa khanyetso ea kutu ea mochini oa mocheso oa poleiti?
Ha e le hantle, poleiti ea Titanium le viton gasket e ke ke ea sebelisoa hammoho.Empa hobaneng?Ke molao-motheo oa ho hanyetsa ho bola oa poleiti ea titanium hore lintho tse peli li ke ke tsa sebelisoa hammoho, hobane poleiti ea titanium e bonolo ho etsa lesela la filimi e sireletsang ea titanium oxide holim'a metsi, lera lena la filimi ea oxide le ka thehoa ka potlako ho oksijene- e nang le tikoloho kamora tshenyeho.'Me sena se lumella ho timetsoa le ho lokisoa (repassivation) ea filimi ea oxide ho bolokoa boemong bo tsitsitseng, ho sireletsa likarolo tsa titanium ka hare ho sebopeho sa timetso e eketsehileng.

Leha ho le joalo, ha tšepe ea titanium kapa motsoako o le tikolohong e nang le fluorine, tlas'a ts'ebetso ea li-ion tsa hydrogen metsing, li-ion tsa fluoride tse tsoang ho viton gasket li sebetsana le tšepe ea titanium ho hlahisa fluoride e qhibilihang, e etsang hore titanium e kene.Reaction equation ke e latelang:
Ti2O3+ 6HF = 2TiF3+ 3H2O
TiO2+ 4HF = TiF4+ 2H2O
TiO2+ 2HF = TiOF2+ H2O
Liphuputso li fumane hore ka tharollo ea acidic, ha mahloriso a ion ea fluoride a fihla ho 30ppm, filimi ea oxidation e holim'a titanium e ka senyeha, e leng se bontšang hore le haeba motsoako o tlaase haholo oa fluoride ion o tla fokotsa haholo ho hanyetsa ha kutu ea lipoleiti tsa titanium.
Ha tšepe ea titanium ntle le tšireletso ea titanium oxide, tikolohong e senyang e nang le hydrogen ea hydrogen evolution, titanium e tla tsoela pele ho monya hydrogen, 'me karabelo ea REDOX e etsahala.Ebe TiH2 e hlahisoa holim'a kristale ea titanium, e potlakisang ho bola ha poleiti ea titanium, ho etsa mapetsong le ho lebisa ho lutla ha mochine oa mocheso oa poleiti.
Ka hona, poleiti ea mocheso oa poleiti, poleiti ea titanium le viton gasket ha ea lokela ho sebelisoa hammoho, ho seng joalo e tla lebisa ho bola le ho hlōleha ha mochine oa mocheso oa poleiti.
Shanghai Heat Transfer Equipment Co., Ltd.(SHPHE) e na le boiphihlelo bo bongata ba ts'ebeletso indastering ea mochini o futhumatsang mocheso oa poleiti, hape e na le lilaboratori tsa 'mele le tsa lik'hemik'hale tse amanang, tse ka tsebang kapele le ka nepo lisebelisoa tsa poleiti le gasket bakeng sa bareki nakong ea pele ea khetho, ho netefatsa ts'ebetso e bolokehileng le e tšepahalang ea lisebelisoa.
