Acrylonitrile mo te NBR

Whakaahuatanga Poto:

Ko te acrylonitrile he wai kore tae ki te kowhai kowhai kowhai me te wai pahekeheke e memeha ana ki te wai me te nuinga o nga whakarewa pararopi pera i te acetone, benzene, carbon tetrachloride, ethyl acetate, me te toluene.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.

Acrylonitrile mo te NBR,
Acrylonitrile mo te NBR Nitrile,Acrylonitrile mo te Acrylonitrile Butadiene Rubber,Acrylonitrile mo te Nitrile rapa,

Ko te NBR (Nitrile), he matū, he copolymer o te butadiene me te acrylonitrile.He rereke nga ihirangi Acrylonitrile i roto i nga hua arumoni mai i te 18% ki te 50%.I te pikinga o te ihirangi NBR, ka piki ake te aukati ki nga hinu turanga hinu me nga hinu waro waro, engari ka heke te ngawari o te pāmahana.

Mo te NBR
Na te pai o te aukati ki nga hua hinu, me tona kaha ki te whakakotahi mo te ratonga i runga i te awhe mahana o -35°C ki +120°C (-30°F ki +250°F), ko Nitrile /NBR te tino whanui. whakamahia te elastomer i roto i te ahumahi hiri i enei ra.He maha hoki nga tohu rapa hoia mo nga wahie me nga mowhiti O-mowhiti aatete hinu e hiahia ana ki nga pūhui nitrile.

Me whakahuahia kia whiwhi pai te aukati ki te iti o te pāmahana, he maha nga wa e tika ana ki te patu i etahi awangawanga teitei.He pai ake nga puhui Nitrile ki te nuinga o nga elastomers e pa ana ki te huinga kōpeketanga, te roimata, me te aukati abrasion.Ko nga pūhui Nitrile karekau he parenga pai ki te ozone, te ra, te rangi ranei.Kaua e penapena tata ki nga motuka hiko me etahi atu taputapu whakaputa ozone.
