Sidee loo doortaa walxaha saxda ah ee xadhig caag ah ee xaaladaha shaqo ee heerkulka aad u sariirta sare (?150?)?

Xaaladaha heerkulka aad u sarreeya (furnaces-ka warshadaha, qaybaha mishiinada, tuubooyinka kiimikada heerkul sarreeya), xulashada agabka waxaa lagu saleeyaa heerka heerkulka dhabta ah:

– 150-180?: EPDM oo adkeysan karta heerkulka sarreeya (qiimo jaban, kuwa aasaasiga ah ee ka hortagga da'da kuleylka);

– 150-200?: FVMQ (caag fluorosilicone ah, iska caabin cimilada oo fiican + iska caabin heerkul sare);

– 200-300?: FFKM (perfluoroelastomer, iska caabinta heerkulka sare ee ugu fiican agabyada caaga, xaaladaha heerkulka sare ee xad-dhaafka ah).

Intaas waxaa dheer, qaab-dhismeedka xariijinta caaga ah waxaa lagu talinayaa inuu isticmaalo naqshad dhaawac yar, iyadoo la kordhinayo dhumucda ku habboon iyo buuxinta kuleylka gudaha si kor loogu qaado u adkeysiga heerkul sare.
