I-Gasket iyisici sokuvala isishintshi sokushisa samapuleti. Idlala indima ebalulekile ekwandiseni ingcindezi yokuvala futhi ivimbele ukuvuza, futhi yenza imidiya emibili igeleze eziteshini zayo zokugeleza ezihlukene ngaphandle kwengxube.
Ngakho-ke, kubaluleke kakhulu ukuqaphela ukuthi i-gasket efanele kufanele isetshenziswe ngaphambi kokusebenzisa isishintshi sokushisa, Ngakho-ke ungayikhetha kanjani i-gasket efanelei-plate heat exchanger?
Ngokuvamile, lokhu okulandelayo kufanele kucatshangelwe:
Ukuthi ihlangabezana nezinga lokushisa lokuklama;
Ukuthi ihlangabezana nengcindezi yokuklama;
Ukuhambisana kwamakhemikhali kwesisombululo semidiya kanye ne-CIP yokuhlanza;
Ukuzinza ngaphansi kwezimo ezithile zokushisa;
Ukuthi izinga lokudla liyacelwa
Izinto ezisetshenziswa kakhulu ze-gasket zihlanganisa i-EPDM, i-NBR ne-VITON, zisebenza emazingeni okushisa ahlukene, izingcindezi kanye nemidiya.
Izinga lokushisa lesevisi ye-EPDM lingu-25 ~ 180 ℃. Ilungele imidiya efana namanzi, umusi, i-ozone, uwoyela wokugcoba ongeyona i-petroleum, i-dilute acid, isisekelo esibuthakathaka, i-ketone, utshwala, i-ester njll.
Izinga lokushisa lesevisi ye-NBR lingu-15 ~ 130 ℃. Ifanele imidiya efana namafutha kaphethiloli, amafutha okugcoba, amafutha ezilwane, amafutha emifino, amanzi ashisayo, amanzi anosawoti njll.
Izinga lokushisa lesevisi ye-VITON ngu-15 ~ 200 ℃. Ilungele imidiya efana ne-sulfuric acid egxilile, i-caustic soda, uwoyela wokudlulisa ukushisa, uwoyela wamafutha otshwala, uwoyela we-asidi kaphethiloli, izinga lokushisa eliphakeme lomusi, amanzi e-chlorine, i-phosphate njll.
Ngokuvamile, izici ezihlukahlukene zidinga ukucatshangelwa ngokugcwele ukuze kukhethwe i-gasket efanelekile yesishintshi sokushisa kwepuleti. Uma kunesidingo, izinto ze-gasket zingakhethwa ngokuhlolwa kokumelana noketshezi.
