· Ayizifanelanga izinyibilikisi zepolar ezifana neeketones, i-ozone, i-nitro hydrocarbons, i-MEK kunye neklorofomu. · Isetyenziselwa ukwenza itanki yamafutha, i-oyile yokuthambisa i-oyile kunye neengxenye zerubha, ngokukodwa iindawo zokutywina, ezisetyenziselwa i-oyile ye-petroleum hydraulic, i-petroli, amanzi, i-silicon grease, ioli ye-silicon, i-diester lubricating oil, i-ethylene glycol hydraulic oil kunye nezinye i-media media. Yeyona isetyenziswa kakhulu kwaye inexabiso eliphantsi lerabha itywina.

FKM

Irabha yeCarbon yeFluoro Naziphi na iindidi ngeendidi ngokuxhomekeke kumxholo wefluorine (isakhiwo se-monomer) yeemolekyuli zefluorine. Ukumelana nokushisa okuphezulu kubhetele kunerubha ye-silicone, inokumelana neekhemikhali ezigqwesileyo, ukuchasana neoli eninzi kunye ne-solvent (ngaphandle kwe-ketone, i-ester), ukumelana nemozulu kunye nokuchasana kwe-ozone; Ukumelana nokubanda kubi, ukusetyenziswa ngokubanzi komgangatho wobushushu -20 ~ 250 ℃. Ifomula ekhethekileyo inokumelana nobushushu obuphantsi ukuya kuthi ga kwi -40 ℃. Izinto eziluncedo:

· Ukumelana nobushushu ukuya kuma-250 ℃

· Ukumelana nee-oyile ezininzi kunye nezinyibilikisi, ngakumbi zonke ii-asidi, i-aliphatic, ivumba elimnandi kunye ne-oyile yezilwanyana kunye nemifuno.

Izinto ezingeloncedo:

· Akukhuthazwa ii-ketones, ii-esters zobunzima obuphantsi bemolekyuli kunye nemixube equlethe i-nitrate. · Iimoto, oololiwe, iinjini zedizili kunye neenkqubo zamafutha.

I-SIL

Itsheyini ephambili yeRubber yeSilicone yenziwe ngesilicon (-si-O-Si) edityaniswe kunye. Ukumelana nobushushu obugqwesileyo, ukumelana nokubanda, ukuxhathisa kwe-ozone, ukumelana nokuguga emoyeni. Ukusebenza kakuhle kokufakelwa kombane. Amandla okuqina erabha eqhelekileyo ahlwempuzekile kwaye akanako ukumelana neoli. Izinto eziluncedo:

Amandla okuqina ukuya kuthi ga kwi-1500PSI kunye nokumelana nokukrazula ukuya kuthi ga kwi-88LBS emva kokwenziwa.

· I-elasticity elungileyo kunye nokuphazamiseka okuhle koxinzelelo

· Ukumelana kakuhle nezinyibilikisi ezingathathi hlangothi

· Ukumelana nobushushu obugqwesileyo

· Ukumelana nokubanda okugqwesileyo

· Ukumelana okugqwesileyo kukhukuliseko lwe-ozone kunye ne-oxide

Ukusebenza okugqwesileyo kokufakelwa kombane

· Ubushushu obugqwesileyo bobushushu kunye nokuchithwa kobushushu

Izinto ezingeloncedo:

· Ayikhuthazwa ukuba isetyenziswe kuninzi lwezinyibilikisi ezigxininisiweyo, i-oyile, i-acids egxininisiweyo kunye ne-diluted sodium hydroxide. • Izitywini okanye iindawo zerabha ezisetyenziswa kushishino lwezixhobo zekhaya, ezifana neePOTS zombane, ii-ayini, iinxalenye zerabha kwii-oveni zemicrowave.

· Iitywina okanye iinxalenye zerabha kushishino lwe-elektroniki, ezifana nezitshixo zefowuni ephathwayo, izinto zokufunxa ukothuka kwiDVD, izitywina kwiintambo zentambo, njl.

· Iitywina kuzo zonke iindidi zamanqaku anxibelelene nomzimba womntu, njengeebhotile zamanzi, imithombo yokusela, njl.

Epdm

Irabha ye-ethylene (i-PPO) i-copolymerized ukusuka kwi-Ethylene kunye ne-propylene kwikhonkco eliphambili kwaye inokumelana nokushisa okukhulu, ukumelana nokuguga, ukuxhathisa kwe-ozone kunye nokuzinza, kodwa ayinakongezwa isulfure. Ukuxazulula le ngxaki, inani elincinci lecandelo lesithathu kunye nekhonkco eliphindwe kabini lingeniswa kwikhonkco eliphambili le-EP, elinokuthi lenziwe ngokufaka isulfure kwi-EPDM. Uluhlu lobushushu ngokubanzi -50 ~ 150 ℃. Ukuchasana okugqwesileyo kwi-solvents ye-polar efana notywala, i-ketone, i-glycol kunye ne-phosphate lipid hydraulic fluids.

Izinto eziluncedo:

· Ukumelana nemozulu elungileyo kunye nokumelana ne-ozone

· Ukumelana kwamanzi okugqwesileyo kunye nokuxhathisa iikhemikhali

· Utywala neeketones zingasetyenziswa

· Ukumelana nobushushu obuphezulu bomphunga, ukunganyameki kakuhle kwirhasi

Izinto ezingeloncedo:

· Akukhuthazwa ukuba kusetyenziswe ukutya okanye ukuba sesichengeni kwihydrogen enevumba elimnandi. • Izitywina zokusingqongileyo komphunga wamanzi wobushushu obuphezulu.

· Izitywini okanye iinxalenye zezixhobo zokuhlambela.

· Amalungu erabha kwisixokelelwano seziqhoboshi (i-braking).

• Izitywina kwiiradiyetha (iitanki zamanzi emoto).
