Gasket ndi chinthu chotseka cha chosinthira kutentha kwa mbale. Chimagwira ntchito yofunika kwambiri pakuwonjezera kuthamanga kwa kutseka ndikuletsa kutuluka kwa madzi, komanso chimapangitsa kuti zinthu ziwirizi ziziyenda kudzera m'njira zawo zoyendera popanda kusakaniza.
Chifukwa chake, ndikofunikira kwambiri kudziwa kuti gasket yoyenera iyenera kugwiritsidwa ntchito musanagwiritse ntchito chosinthira kutentha, Chifukwa chake momwe mungasankhire gasket yoyenerachosinthira kutentha kwa mbale?
Kawirikawiri, zinthu zotsatirazi ziyenera kuganiziridwa:
Kaya ikukwaniritsa kutentha kwa kapangidwe kake;
Kaya ikukwaniritsa kukakamizidwa kwa kapangidwe;
Kugwirizana kwa mankhwala pa zofalitsa ndi njira yoyeretsera ya CIP;
Kukhazikika pansi pa kutentha kwinakwake;
Kaya chakudya chikufunidwa
Zipangizo zomwe zimagwiritsidwa ntchito kwambiri ndi gasket zimaphatikizapo EPDM, NBR ndi VITON, zomwe zimagwiritsidwa ntchito kutentha kosiyanasiyana, kupsinjika ndi media.
Kutentha kwa ntchito ya EPDM ndi - 25 ~ 180 ℃. Ndi yoyenera kugwiritsa ntchito zinthu monga madzi, nthunzi, ozone, mafuta odzola osagwiritsa ntchito mafuta, asidi wosungunuka, maziko ofooka, ketone, mowa, ester ndi zina zotero.
Kutentha kwa ntchito ya NBR ndi - 15 ~ 130 ℃. Ndikoyenera kugwiritsa ntchito zinthu monga mafuta amafuta, mafuta odzola, mafuta a nyama, mafuta a masamba, madzi otentha, madzi amchere ndi zina zotero.
Kutentha kwa ntchito ya VITON ndi - 15 ~ 200 ℃. Ndi yoyenera kugwiritsa ntchito zinthu monga sulfuric acid yokhazikika, caustic soda, mafuta osinthira kutentha, mafuta a mowa, mafuta a asidi, nthunzi yotentha kwambiri, madzi a chlorine, phosphate ndi zina zotero.
Kawirikawiri, zinthu zosiyanasiyana ziyenera kuganiziridwa mokwanira kuti musankhe gasket yoyenera yosinthira kutentha kwa mbale. Ngati kuli kofunikira, zinthu za gasket zitha kusankhidwa kudzera mu mayeso oletsa madzi.
