Lintho tse ikhethileng tsa NBR/EPDM/FKM/SIL Rubber O-Ring

NBR

Nitrile Rubber e lokiselitsoe ke copolymerization ea acrylonitrile le butadiene.Likahare tsa acrylonitrile li tloha ho 18% ho ea ho 50%.Ha litaba tsa acrylonitrile li phahame, ho ka ba molemo ho hanyetsa oli ea mafura a hydrocarbon, empa ts'ebetso e tlase ea mocheso e mpe le ho feta, mocheso o tloaelehileng oa tšebeliso ke -40 ~ 120 ℃.Butanol ke e 'ngoe ea rabara e sebelisoang haholo bakeng sa litiiso tsa oli le li-O-rings.

Melemo:

· Ho hanyetsa hantle oli, metsi, solvent le oli ea khatello e phahameng.

· 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 sebelisoa 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 ho noa, 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 ho sebelisoa ha 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 li-radiator (litanka tsa metsi a koloi).
