Babban kayanroba fadada hadin gwiwasune: silica gel, roba nitrile, neoprene, roba EPDM, roba na halitta, roba roba da sauran roba.
Kaddarorin jiki suna halin juriya ga mai, acid, alkali, abrasion, high da low yanayin zafi.
1. roba na halitta
Roba roba gidajen abinci da high elasticity, high elongation ƙarfi, mai kyau lalacewa juriya da fari juriya, kuma za a iya amfani da a yanayin zafi jere daga -60 ℃ zuwa +80 ℃.Matsakaici na iya zama ruwa da gas.
2. Butyl roba
Ana amfani da haɗin gwiwar roba mai jurewa sawa a cikin bututun ƙura da tsarin yashi.Ƙwararren roba mai jure lalacewa da lalata ƙwararrun haɗin gwiwa ne na roba wanda aka kera musamman don tsarin lalata.Yana yana da kyau lalacewa juriya, acid da alkaline juriya, lalata juriya, da kuma iya yadda ya kamata rama ga axial fadada, radial fadada, angular kaura da sauran ayyuka na desulfurization bututu.
3. Chloroprene roba (CR)
Haɗin roba mai jure ruwan teku, wanda ke da kyakkyawan iskar oxygen da juriya na ozone, don haka juriyar tsufa yana da kyau musamman.Yanayin zafin aiki: kusan -45 ℃ zuwa + 100 ℃, tare da ruwan teku a matsayin babban matsakaici.
4. Nitrile roba (NBR)
hadin roba mai juriya.Halin yana da kyau juriya ga iskar gas.Yanayin zafin aiki: kusan -30 ℃ zuwa + 100 ℃.Samfurin da ya dace shine: haɗin roba mai jure wa mai, tare da najasa a matsayin matsakaici.
5. Ethylene propylene diene monomer (EPDM)
Acid da alkali resistant roba gidajen abinci yawanci amfani, halin da acid da alkali juriya, tare da zazzabi kewayon -30 ℃ zuwa +150 ℃.Samfurin da ya dace: acid da alkali resistant roba hadin gwiwa, matsakaici ne najasa.
Fluorine roba (FPM) robar haɗin gwiwa mai zafi mai zafi shine tsarin samar da aikin noma elastomer da aka samar ta hanyar copolymerization na fluorine mai ɗauke da monomers.Halinsa shine juriya mai girma har zuwa 300 ℃.

Rabewa da halayen aiki
Dangane da amfani, akwai nau'ikan iri ukuEPDM roba(wanda aka fi buƙata don juriya na ruwa, juriya na ruwa, da juriya na tsufa), roba na halitta (wanda aka fi amfani dashi don roba wanda kawai ke buƙatar elasticity), butyl rubber (rubber wanda ke buƙatar kyakkyawan aikin rufewa), robar nitrile (roba mai buƙatar juriya mai). da silicone (rubber matakin abinci);
Ana amfani da roba mai rufewa sosai a masana'antu irin su antistatic, mai kare harshen wuta, lantarki, sinadarai, magunguna, da abinci.
An rarraba kayan haɗin gwiwar roba zuwa nau'i daban-daban dangane da matsakaicin da aka yi amfani da su, kamar chloroprene rubber, butyl rubber, fluoro rubber, EPDM roba da na halitta roba.Ana amfani da haɗin gwiwar roba masu sassaucin ra'ayi a cikin hanyoyin haɗin bututu daban-daban, tare da halayen aiki na ɗaukar girgiza, raguwar hayaniya, da ramuwa.
Ayyukan haɗin gwiwar roba ya bambanta dangane da kayan da aka yi amfani da su.Bambancin ayyuka kuma ya haɗa da fluororubber na musamman da roba na silicone, waɗanda ke da juriya da juriya, juriya, da juriya mai zafi.Yana da juriyar mai, acid da alkali, juriya da sanyi da zafi, juriyar tsufa, da dai sauransu. Dangane da gyare-gyare, ana iya yin roba iri daban-daban na haɗin gwiwa na fadada roba.
