1. rapa maori
Ko te rapa taiao he ngawari ki te whiwhi kirihou.Ko te pokey me te iti o te rapa maleic paerewa he iti te pokey tuatahi me te tikanga karekau e hiahia ki te kirihou.Mena ka neke ake te pokey Mooney o etahi atu momo whakapiri paerewa i te 60, me hanga tonu.I te wa e whakamahi ana i te whakaranu a-roto mo te hanga, he 3-5 meneti pea ka eke te pāmahana ki runga ake i te 120 ℃.A, no te tāpiri plasticizers plasticizers ranei, ka taea e tino whakapoto i te wa plasticizing me te whakapai ake i te pānga plasticizing.
2. Styrene-butadiene
Ko te tikanga, ko te pokey Mooney o Styrene-butadiene te nuinga kei waenga i te 35-60.No reira, kare ano hoki a Styrene-butadiene e whakakikoruatia.Engari ko te mea pono, i muri i te whakakikorua, ka taea te whakapai ake i te whakamararatanga o te kaihoko whakahuihui, e awhina ana ki te whakapai ake i te kounga o te hua.Ina koa mo nga hua rapa hautai, he ngawari te pahuka a Styrene-butadiene i muri i te whakakikorua, a he rite te rahi o te mirumiru.
3. Polybutadiene
Ko te Polybutadiene he taonga rere makariri, a, ehara i te mea ngawari ki te whakapai ake i te paanga o te kirihou.I tenei wa, ko te pokey Mooney o te Polybutadiene e whakamahia nuitia ana kua whakahaeretia i roto i te awhe e tika ana i te wa o te polymerization, na reira ka taea te whakauru tika me te kore he kirihou.
4. Neoprene
Ko te Neoprene i te nuinga o te waa kaore e hiahiatia kia kirihouhia, engari na te kaha o te uaua, he pai mo te mahi.Ko te 30 ℃ -40 ℃ te paemahana paahi angiangi, he ngawari ki te piri ki te pukapuka mena he tiketike rawa.
5. Ethylene propylene rapa
Na te hanganga kukū o te mekameka matua o te Ethylene propylene rapa, he uaua ki te hanga i te pakaru o te ngota ma te kirihou.No reira, he mea tika kia whakahiatohia kia pai ai te pokey Mooney me te kore e hiahiatia mo te hanga.
6. Puti rapa
Butyl rapa he hanganga matū pūmau, me te ngohengohe, iti taimaha rāpoi me te wē nui, na e kore te mea nui te pānga plasticizing mīhini.Ko te rapa Butyl me te iti o te pokey Mooney ka taea te whakauru tika me te kore he kirihou.
7. Nitrile rapa
Ko te rapa Nitrile he iti te kirihou, he uaua teitei me te whakaputa wera nui i te wa e whakakikoruatia ana.Na reira, ko te iti o te pāmahana, te iti o te kaha me te whakakikorua i te waahanga ka whakamahia i roto i te mira tuwhera ki te whakatutuki i nga hua pai.Kaua te rapa Nitrile e whakakikoruatia ki roto i te whakaranu o roto.I te mea ko te rapa Nitrile ngohe he ahua kirihou, ka taea te whakauru tika me te kore parani kirihou.
