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 tiisang ka sehatsetsi sa R12, lisebelisoa tsa ka tlung. E loketse lihlahisoa tsa rabara tse kopanang ka kotloloho le sepakapaka, khanya ea letsatsi, likarolo tsa ozone, tse hananang le mollo le ho bola ha lik'hemik'hale.
Setifikeiti:
KTW W270 EN681-1,ACS,NSF61/372;WRAS,EC1935;FDA,EC1935;REACH,ROHS
Melemo ea rona:
1. Rubber le lisebelisoa tsa moralo li tlamahane ka thata.
2. E babatsehang rabara elasticity le compression sete.
3. Boholo bo tsitsitseng ba setulo le torque e nyenyane, ho tiisa ho babatsehang le ho roala thepa ea ho hanyetsa.
4. Lisebelisoa tsa rabara li amohela lihlahisoa tsa machaba tse nang le ts'ebetso e tsitsitseng.
5. Boitsebiso: CR, NR, SBR, NBR, EPDM, PTFE, Silicone, joalo-joalo.
6. Setifikeiti: NSF, SGS,KTW,FDA,ISO9001,ROHS,
7. Ho hanyetsa mocheso o phahameng / o tlase, ho hanyetsa oli le mafura, ho thibela moea o motle joalo-joalo.
8. Ts'ebetso le ho paka ho latela litlhoko tsa hau.
9. Kopo: Taolo ea metsi, elektroniki, lisebelisoa tsa ntlo, likoloi, indasteri ea lisebelisoa tsa bongaka, mochini oa indasteri & likarolo, joalo-joalo.
