1. Hanyar wakilcin hatimin mai

Hanyoyin wakilci gama gari:

Nau'in hatimin mai - diamita na ciki - diamita na waje - tsayi - abu

Misali, TC30 * 50 * 10-NBR tana wakiltar hatimin kwarangwal na lebe biyu tare da diamita na ciki 30, diamita na waje 50, da kauri na 10, wanda aka yi da robar nitrile.

2.Material na kwarangwal mai hatimi

Nitrile roba (NBR): lalacewa-resistant, mai resistant (ba za a iya amfani da iyakacin duniya kafofin watsa labarai), zazzabi resistant: -40 ~ 120 ℃.

Hydrogenated nitrile roba (HNBR): Wear juriya, mai juriya, tsufa juriya, zazzabi juriya: -40 ~ 200 ℃ (ƙarfi fiye da NBR zafin jiki juriya).

Fluorine m (FKM): acid da alkali resistant, mai resistant (resistant ga duk mai), zafin jiki resistant: -20 ~ 300 ℃ (mafi kyawun juriya mai fiye da na sama biyu).

Polyurethane roba (TPU): Juriya juriya, juriya tsufa, juriya zafin jiki: -20 ~ 250 ℃ (kyakkyawan juriya tsufa).

Silicone roba (PMQ): zafi-resistant, sanyi resistant, tare da kananan matsawa m nakasawa da kuma low inji ƙarfi.Zazzabi juriya: -60 ~ 250 ℃ (mafi kyau zazzabi juriya).

Polytetrafluoroethylene (PTFE): yana da kyakkyawan kwanciyar hankali na sinadarai, juriya ga kafofin watsa labaru daban-daban kamar acid, alkali, da mai, juriya da juriya mai zafi, ƙarfin injina mai ƙarfi, da kyawawan kaddarorin lubricating.

Gabaɗaya magana, kayan da aka saba amfani da su don hatimin kwarangwal sune roba nitrile, fluororubber, robar silicone, da polytetrafluoroethylene.Saboda kyawawan kaddarorin sa mai da kansa, musamman idan an ƙara shi da tagulla, tasirin ya fi kyau.Ana amfani da su duka don yin zoben riƙewa, zoben Glee, da sanduna.
