Acrylonitrile mo Acrylonitrile Butadiene Rubber
Acrylonitrile mo Acrylonitrile Butadiene Rubber,
Acrylonitrile Mo te NBR, Acrylonitrile Mo te Nitrile Rubber,
Ko te NBR, te Buna-N, me te nitrile e tohu ana i te elastomer kotahi i runga i te copolymer butadiene me te acrylonitrile.Ko te Nitrile he atete ki nga wai waipēhi, hinu whakahinu, wai tuku me etahi atu hua hinu kore-polar na te hanganga polar o tenei elastomer.Ko nga nitriles ano he atete ki te hau me te taiao wai.

Mōkī me te Tukunga
Tono Hua
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.
