Acrylonitrile maka NBR,
Acrylonitrile Maka Nitrile Rubber,
Nitrile (a na-akpọkarị buna-N roba ma ọ bụ perbunan) bụ elastomer a na-ejikarị eme ihe na ụlọ ọrụ akara.Nitrile bụ copolymer nke monomers abụọ: acrylonitrile (ACN) na butadiene.A na-ekpebi njirimara nke ogige rọba ndị a site na ọdịnaya ACN ya, nke na-ekewa n'ime nhazi atọ:
Nitrile dị elu>45% ACN ọdịnaya,
Ọdịnaya nitrile 30-45% ACN,
Nitrile dị ala <30% ACN.
Ka ọdịnaya ACN dị elu, ka ọ ka mma iguzogide mmanụ hydrocarbon.Ọdịnaya ACN dị ala ka ọ ka mma mgbanwe ya na ngwa okpomọkụ dị ala.Ọkara nitrile bụ, ya mere, akọwapụtara nke ọma n'ihi nguzozi ya n'ozuzu ya n'ọtụtụ ngwa.Dị ka ọ na-adịkarị, enwere ike ịgbakọta nitriles ka ọ rụọ ọrụ n'ogo okpomọkụ nke -35 ° C ruo + 120 Celsius ma dị elu karịa ọtụtụ elastomer n'ihe gbasara nhazi mkpakọ, akwa na mgbochi abrasion.
