Usetyenziso oluqhelekileyo
Izitywina zeenjini zeemoto, iithumbu zamafutha, kunye neegaskets kwizixhobo zepetrochemical.
3. Irabha yeSilicone (VMQ)
Iimpawu zoMsebenzi
Ubushushu obugqithisileyo: -60℃ukuya kwi-250℃(inkonzo eqhubekayo), kunye nokuzinza kwe-thermal ukuya kwi-300 degree.
Biocompatibility: USP Class VI eqinisekisiweyo kwizicelo zonyango.
Ukulinganiselwa: Amandla aphantsi weenyembezi (<10 kN/m) and poor oil resistance.
Usetyenziso oluqhelekileyo
Iikhathetha zonyango, izitywini ze-aerospace, kunye{0}}negasthi yobushushu obuphezulu kwimveliso yesemiconductor.
4. Irabha yeChloroprene (CR)
Iimpawu zoMsebenzi
Ukumelana neMozulu: Ozone resistance class A (ASTM D1149), UV stability >Iminyaka emi-5 ngaphandle.
Uluhlu lobushushu: -30°C to 100°C, with flame-retardant properties (oxygen index >38).
Amandla oomatshini: Amandla okuqina 25–35 MPa, ukuxhathisa ukukrazula 30–40 kN/m.
Usetyenziso oluqhelekileyo
Ukugqunywa kweengcingo kunye nekheyibhile, iinwebu zokuphahla, kunye neelitha zamathumbu omlilo.
5. I-Fluoroelastomer (FKM)
Iimpawu zoMsebenzi
Ukumelana nemichiza: Ukumelana ne-H₂SO₄ (98%), i-NaOH (50%), kunye namafutha eenqwelomoya.
Uluhlu lobushushu: - i-20℃ukuya kwi-260 degree, kunye nokuzinza kwexesha elifutshane ukuya kwi-300 degree.
Iipropati zoomatshini: Amandla okuqina 15–20 MPa, iseti yoxinzelelo<20% at 200°C for 70h.
Usetyenziso oluqhelekileyo
Izitywina kwiireactors zekhemikhali, izixhobo ze-injini ye-aerospace, kunye nezixhobo ze-oyile ye-downhole.
