Anti-phoofolo le oli ea meroho e nepahetsengNeoprene (CR) Butterfly Valve Seat
Neoprene (CR)
Neoprene, Polychloroprene e entsoe ka chloroprene monomer polymerization. Ka mor'a vulcanization, e na le elasticity e ntle ea rabara le ho hanyetsa abrasion. Ke anti-insolation 'me e na le khanyetso e ntle ea boemo ba leholimo, e hanyetsanang le ho sotha ka mabifi, lihatsetsi, dilute acid, silicon ester lubricant, empa e sa hanyetse letoto la phosphate la oli ea hydraulic. Ho bonolo ho khanya le ho thatafala ka mocheso o tlase, botsitso bo fokolang ba polokelo, le katoloso e kholo sebakeng se tlase sa aniline sa oli ea diminerale. Ha u sebelisa mocheso oa mocheso ke - 50-150 likhato.
Melemo:
Elasticity e ntle le deformation e ntle ea compression, foromo ha e na sebabole, kahoo ho bonolo haholo ho e sebetsa. E na le thepa e khahlanong le - liphoofolo le oli ea meroho, e ke ke ea angoa ke lik'hemik'hale tse sa jeleng paate, mafura, oli, mefuta e fapaneng ea oli, li-solvents, hape e na le thepa e khahlanong le mollo.
Mefokolo:
U se ke ua khothaletsa ho sebelisa li-acids tse matla, nitrohydrocarbons, esters, chloroform le lik'hemik'hale tsa ketone.
Kopo:
Likarolo tsa rabara kapa likarolo tse koalang ka sehatsetsi sa R12, lisebelisoa tsa ntlo. E loketse lihlahisoa tsa rabara tse kopanang ka kotloloho le sepakapaka, khanya ea letsatsi, likarolo tsa ozone, tse hananang le mollo le kutu ea lik'hemik'hale.

E entsoe ka mokhoa o nepahetseng ka ho fetisisa, setulo sa rona sa valve ea serurubele ke motsoako o lumellanang oa rabara ea PTFE (Polytetrafluoroethylene) le EPDM (Ethylene Propylene Diene Monomer). Motsoako ona o ikhethang ha o netefatse feela ho tšoarella ho holimo ha sehlahisoa empa hape o tiisa ho ikamahanya le maemo ho pholletsa le maemo a fapaneng a ts'ebetso. Setulo sa belofo e ntšo-'mala se entsoe ka boqhetseke ho mamella ho fetoha ha mocheso ho tloha -50 ho ea ho +150 likhato tsa Celsius, e leng se etsang hore e be tharollo e loketseng bakeng sa ho laola metsi, metsi a nooang, metsi a nooang le metsi a litšila. Bohlokoa ba ho sebelisa PTFE+EPDM liner ka valve ea serurubele e ke ke ea fetisoa. PTFE, e tsebahalang ka ho hanyetsa lik'hemik'hale ka mokhoa o ikhethang, e sebetsa ka mokhoa o phethahetseng ka ho tiea le ho tiea ha rabara ea EPDM, e netefatsang hore ha ho na moroallo le ho lutla-tiiso e netefatsang bopaki. Motsoako ona oa synergistic o matlafatsa botsitso ba setulo sa valve ea serurubele, ka ho etsa joalo se netefatsa hore se lekana hantle le ho felisa likotsi tsa ho lutla ho ka bang teng. Setulo sa rona sa Elastic Butterfly Valve Seat ha se karoloana feela; ke boitlamo mabapi le katleho, polokeho, le ts'ireletso ea tikoloho. Ebang ke bakeng sa tsamaiso ea metsi a bolulo kapa tsamaiso ea metsi a litšila a indasteri, setulo sa rona sa li-valve se eme e le lejoe la motheo le tšepahalang la lisebelisoa tsa ho laola metsi. Ka Sansheng Fluorine Plastics, ha u khethe sehlahisoa feela; u khetha molekane ea inehetseng ho bokhabane le popontshwa ho matla a mokelikeli.
