Acrylonitrile mo te NBR,
Acrylonitrile Mo te Nitrile Rubber,
Ko te Nitrile (e kiia ana ko te buna-N rapa, ko te perbunan ranei) te elastomer e whakamahia nuitia ana i roto i te umanga hiri.Ko te Nitrile he copolymer o nga monomers e rua: acrylonitrile (ACN) me te butadiene.Ko nga ahuatanga o enei puhui rapa e whakatauhia ana e ona ihirangi ACN, ka wehewehea kia toru nga whakarōpūtanga:
Nitrile teitei> 45% ihirangi ACN,
Nitrile Waenga 30-45% ihirangi ACN,
Nitrile iti <30% ihirangi ACN.
Ko te teitei ake o te ihirangi ACN, ko te pai ake o te aukati ki nga hinu waiwaro.Ko te iti o te ihirangi ACN ka pai ake tona ngawari ki nga tono pāmahana iti.Ko te nitrile Waenga, na te mea he pai te toenga i roto i te nuinga o nga tono.Ko te tikanga, ka taea te whakakotahi i nga nitriles ki te mahi i runga i te awhe pāmahana o -35°C ki te +120°C he pai ake i te nuinga o nga elastomers e pa ana ki te huinga kōpeketanga, te roimata me te aukati abrasion.

Ko te Acrylonitrile he mea hanga arumoni na roto i te ammoxidation propylene, ka tauhohehia te propylene,ammonia, me te hau e te whakakorikori i roto i te moenga wai.Ka whakamahia te Acrylonitrile hei monomer tahi i roto i te hanga o nga muka kiriaku me nga muka modacrylic.Ko nga whakamahinga ko te hanga kirihou, paninga mata, elastomers nitrile, kapia arai, me te whakapiri.He takawaenga matū hoki i roto i te whakahiato o nga momo antioxidants, ho'oraa, waikano, me te mahi-mata.
1. Acrylonitrile hanga o polyacrylonitrile muka, ara kiriaku muka.
2. Ka taea te kape i te kirikiri me te butadiene ki te hanga i te rapa nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized ki te taka ABS resin.
4. Ka taea e te waikura Acrylonitrile te whakaputa acrylamide, waikawa kiriaku me ona hākawa.
