Acrylonitrile don NBR
Acrylonitrile don NBR,
Acrylonitrile Don Nitrile Rubber,
Nitrile (wanda aka fi sani da buna-N roba ko perbunan) shine mafi yawan amfani da elastomer a cikin masana'antar hatimi.Nitrile copolymer ne na monomers guda biyu: acrylonitrile (ACN) da butadiene.Abubuwan da ke cikin waɗannan mahadi na roba an ƙaddara su ta hanyar abun ciki na ACN, wanda ya kasu kashi uku:
Babban nitrile> 45% abun ciki na ACN,
Matsakaicin nitrile 30-45% abun ciki na ACN,
Ƙananan nitrile <30% abun ciki na ACN.
Mafi girman abun ciki na ACN, mafi kyawun juriya ga mai.Ƙarƙashin abun ciki na ACN shine mafi kyawun sassauci a aikace-aikacen ƙananan zafin jiki.Matsakaicin nitrile shine, saboda haka, mafi yadu ƙayyadadde saboda kyakkyawan ma'aunin sa gaba ɗaya a yawancin aikace-aikace.Yawanci, ana iya haɗa nitriles don yin aiki akan kewayon zafin jiki na -35 ° C zuwa + 120 ° C kuma sun fi yawancin elastomers dangane da saitin matsawa, tsagewa da juriya.
