Acrylonitrile fun NBR,
Acrylonitrile Fun Nitrile Rubber,
Nitrile (eyiti a tọka si bi buna-N roba tabi perbunan) jẹ elastomer ti o wọpọ julọ ni ile-iṣẹ edidi.Nitrile jẹ copolymer ti awọn monomers meji: acrylonitrile (ACN) ati butadiene.Awọn ohun-ini ti awọn agbo ogun roba wọnyi jẹ ipinnu nipasẹ akoonu ACN rẹ, eyiti o fọ si awọn ipin mẹta:
Nitrile giga>45% akoonu ACN,
Nitrile alabọde 30-45% akoonu ACN,
Nitrile kekere <30% akoonu ACN.
Awọn akoonu ACN ti o ga julọ, ti o dara julọ resistance si awọn epo hydrocarbon.Isalẹ akoonu ACN dara ni irọrun rẹ ni awọn ohun elo iwọn otutu kekere.Nitrile alabọde jẹ, nitorinaa, pato ni ibigbogbo nitori iwọntunwọnsi gbogbogbo ti o dara ni ọpọlọpọ awọn ohun elo.Ni deede, awọn nitriles le ṣe idapọpọ lati ṣiṣẹ lori iwọn otutu ti –35°C si +120°C ati pe o ga ju ọpọlọpọ awọn elastomers ni iyi si ṣeto funmorawon, yiya ati abrasion resistance.
