Ngokudibanisa amaqondo okushisa aphezulu, uxinzelelo oluphezulu kunye nokuvezwa okunzima kwiikhemikhali ezinobunzima, i-elastomers yerabha inyanzelekile ukuba yenze kwiindawo ezinzima kwishishini leoli kunye negesi.Ezi zicelo zifuna izinto ezihlala ixesha elide kunye noyilo olufanelekileyo lwesitywina ukuze luphumelele.Ishishini leoli kunye negesi ngokuqhelekileyo lifuna i-o-ring ye-rubber yokuhlola, ukutsalwa, ukucocwa kunye nokuthutha.Nanku ujongo olusondeleyo kwezona zisombululo zokutywina ezingcono zokujongana nezi zicelo.
Ukukhetha Umbandela Ofanelekileyo
Yonke impahla yerabha ineempawu zayo ezizodwa ezenza ukuba zilungele izicelo ezithile kunye namashishini.Kwioli kunye negesi, izisombululo zokutywinwa kufuneka zibonise ukuxhathisa kwe-corrosion, ukuzinza phantsi koxinzelelo, ukumelana nobushushu kunye nokuzinza kweekhemikhali.
Ezinye zezona mathiriyeli zibalaseleyo kolu shishino ziquka:
FKM
I-Nitrile (Buna-N)
HNBR
Silicone/Fluorosilicone
AFLAS®
Kubalulekile ukuqonda izakhono zemathiriyeli nganye ukuqinisekisa ukuba isetyenziswa kweyona ndawo ilungileyo.Ngolwazi oluthe vetshe malunga nokukhetha imathiriyeli, ndwendwela iSikhokelo soKhetho lweMathiriyeli.
Sebenzisa amatywina obuso kwiZindlu zeMetal
Iigaskets zihlala zisetyenziselwa ukusetyenziswa kweoli kunye negesi ukukhusela imixholo yangaphakathi yeeyunithi zezindlu zetsimbi ekungcoleni.Nangona kunjalo, izitywina zobuso zibonakaliswe ukuba zigqithise ii-gaskets ezisikiweyo kwizicelo zezindlu zentsimbi, zizenza isisombululo esiphezulu sokutywina.
Iinzuzo eziphambili zokutywinwa kobuso ziquka:
Unyamezelo oluchanekileyo olubunjiweyo
Indawo yoqhagamshelwano yomthwalo
Amandla oxinzelelo asezantsi ayafuneka
Ngcono ifunxa iiyantlukwano kumphezulu womphezulu
Ukuqinisekisa impumelelo, yonke itywina yobuso kufuneka yenziwe ngokuphakama kwedlala elifanelekileyo ukubonelela ubungakanani obufanelekileyo bokucudisa kwi-o-ring cross cross section.Ukongeza, kufuneka kuhlale kukho idlala elilambathayo kunomthamo wokutywina kulo lonke uyilo lwetywina.Ezi zinto kufuneka zihlale ziqwalaselwe xa kuyilwa isitywina sobuso obuyimpumelelo kwi-oyile kunye ne-gas applications.Ngelixa i-oyile kunye ne-gas industry ineemfuno eziqinileyo zokusombulula ukutywinwa okuphumelelayo, izinto ezifanelekileyo, uhlobo lwesitywina kunye neempawu zokuyila ziya kubeka isicelo sakho kwimpumelelo.
Ngaba uyafuna ukuthetha ngakumbi malunga nokutywinwa kwezicelo zeoyile negesi?
