· Ho kheloha ha khatello e ntle, ho hanyetsa le ho lelefatsa.
Mefokolo:
· Ha e lokele lihlapolli tsa polar tse kang ketone, ozone, nitro hydrocarbons, MEK le chloroform. · E sebelisetsoa ho etsa tanka ea mafura, tanka ea oli e tlotsang le likarolo tsa rabara, haholo-holo likarolo tsa ho tiisa, tse sebelisoang ka oli ea petroleum hydraulic, peterole, metsi, silicon grease, oli ea silicon, oli ea diester lubricating, ethylene glycol hydraulic oli le mecha e meng ea metsi. Ke tiiso ea rabara e sebelisoang ka ho fetisisa le e theko e tlaase ka ho fetisisa.
FKM
Fluoro Carbon Rubber Mofuta ofe kapa ofe oa mefuta e fapaneng ho latela litaba tsa fluorine (sebopeho sa monoma) sa limolek'hule tsa fluorine. Ho hanyetsa mocheso o phahameng ho molemo ho feta rabara ea silicone, e na le lik'hemik'hale tse ntle haholo tse hanyetsang, ho hanyetsa boholo ba oli le solvent (ntle le ketone, ester), ho hanyetsa boemo ba leholimo le ho hanyetsa ozone; Ho hanyetsa serame ho futsanehile, tšebeliso e akaretsang ea mocheso oa -20 ~ 250 ℃. Foromo e khethehileng e ka mamella mocheso o tlase ho fihlela ho -40 ℃. Melemo:
· Ho hanyetsa mocheso ho 250 ℃
· E hanana le lioli le lihlapolli tse ngata, haholo li-acids, aliphatic, monko le oli ea liphoofolo le ea meroho.
Mefokolo:
· Ha e khothalletsoe bakeng sa li-ketone, li-esters tsa boima bo tlase ba limolek'hule le metsoako e nang le nitrate. · Likoloi, li-locomotives, lienjine tsa diesel le lisebelisoa tsa mafura.
SILE
Ketane e kholo ea Silicone Rubber e entsoe ka silicon (-si-O-Si) e kopantsoeng hammoho. Ho hanyetsa mocheso o babatsehang, ho hanyetsa serame, ho hanyetsa ozone, ho hanyetsa botsofali ba sepakapaka. Ts'ebetso e ntle ea insulation ea motlakase. Matla a tsitsitseng a rabara e tloaelehileng a fokola 'me ha a na ho hanyetsa oli. Melemo:
· Matla a ho fihla ho 1500PSI le ho hanyetsa meokho ho fihla ho 88LBS kamora ho etsoa
· Elasticity e ntle le khatello e ntle ea compression
· Ho hanyetsa hantle li-solvents tse sa nke lehlakore
· Excellent mocheso ho hanyetsa
· E babatsehang ho hanyetsa serame
· Ho hanyetsa ho hoholo ha ozone le khoholeho ea oxide
Ts'ebetso e ntle ea ho kenya motlakase
· Mocheso o motle ka ho fetisisa le ho senya mocheso
Mefokolo:
· Ha e khothalletsoe ho sebelisoa ka bongata bo bongata ba metsoako e hlapollang, oli, concentrated acids le diluted sodium hydroxide. • Litiiso kapa likarolo tsa rabara tse sebelisoang indastering ea lisebelisoa tsa lapeng, joalo ka LIPOTS tsa motlakase, liaene, likarolo tsa rabara ka liontong tsa microwave.
· Litiiso kapa likarolo tsa rabara indastering ea elektroniki, joalo ka linotlolo tsa mehala ea thekeng, li-shock absorbers ka DVD, li-seals ka li-cable joints, joalo-joalo.
· Litiiso tsa mefuta eohle ea lintho tse amanang le 'mele oa motho, joalo ka libotlolo tsa metsi, liliba tsa metsi, joalo-joalo.
Epdm
Ethylene Rubber (PPO) e entsoe ka copolymerized ho tloha Ethylene le propylene ka ketane e kholo 'me e na le ho hanyetsa mocheso o babatsehang, ho hanyetsa botsofali, ho hanyetsa ozone le botsitso, empa e ke ke ea eketsoa sebabole. Ho rarolla bothata bona, karolo e nyenyane ea karolo ea boraro e nang le ketane e habeli e kenngoa ka har'a ketane e kholo ea EP, e ka thehoang ka ho eketsa sebabole ho EPDM. Thempereichara e akaretsang ke -50 ~ 150 ℃. Ho hanyetsa ka mokhoa o babatsehang ho li-solvents tsa polar tse kang joala, ketone, glycol le phosphate lipid hydraulic fluids.
Melemo:
· Ho hanyetsa boemo ba leholimo bo botle le ho hanyetsa ozone
· Ho hanyetsa metsi ka mokhoa o babatsehang le ho hanyetsa lik'hemik'hale
Ho ka sebelisoa lino tse tahang le li-ketone
· Mocheso o phahameng oa ho hanyetsa mouoane, ho se khonehe hantle ho khase
Mefokolo:
· Ha e khothalletsoe bakeng sa tšebeliso ea lijo kapa ho pepesehela hydrogen e nkhang hamonate. · Litiiso bakeng sa tikoloho ea mocheso o phahameng oa mouoane oa metsi.
· Litiiso kapa likarolo tsa thepa ea ho hlapela.
· Likarolo tsa rabara tsamaisong ea braking (braking).
· Litiiso ka har'a li-radiator (litanka tsa metsi a koloi).
