Indlela yokukhetha impahla efanele ye-rubber strip ukuze ifanele izimo zokusebenza eziphezulu kakhulu (±150°C)?

Ezimweni zokushisa okuphezulu kakhulu (izinkukhu zezimboni, izindawo zokusebenza zamajubane, imigudu yemithi eshisayo), ukukhetha izinto kusekelwe ebangeni lokushisa langempela:

– 150-180?: EPDM elwa nezinga lokushisa eliphezulu (ebiza kahle, eyisisekelo yokulwa nokuguguleka kokushisa);

– 150-200?: FVMQ (i-fluorosilicone rubber, ukumelana nezimo zokukhanya kanye nokumelana nezinga lokushisa eliphezulu);

– 200-300?: FFKM (perfluoroelastomer, okuwumkhiqizo onokumelana okuphezulu kakhulu nokushisa phakathi kwezinto zokwenziwa, ukuze izimo zokushisa eziphezulu kakhulu).

Ngaphezu kwalokho, kunconywa ukuba isakhiwo se-rubber strip sisebenzise design ephansi yokucindezela-nokuqhekeka, enokwenyuka okufanelekayo kobubanzi kanye nokugcwalisa okukhahlela ukushisa ngaphakathi ukuze kuthuthukiswe ukufaneleka kokushisa okuphezulu.
