Acrylonitrile ee NBR
Acrylonitrile ee NBR,
Acrylonitrile oo loogu talagalay Rubber Nitrile,
Nitrile (badanaa loo yaqaan buna-N rubber ama perbunan) waa elastomer-ka ugu badan ee loo isticmaalo warshadaha shaabadda.Nitrile waa copolymer ka kooban laba monomers: acrylonitrile (ACN) iyo butadiene.Astaamaha xeryahooda caagga ah waxaa lagu go'aamiyaa nuxurka ACN, kaas oo loo kala qaybiyay saddex qaybood:
Nitrile sare>45% waxa ku jira ACN,
Nitrile dhexdhexaad ah 30-45% ACN,
Nitrile hoose <30% ACN ka kooban yahay.
Mar kasta oo ay ka kooban tahay ACN, way ka sii fiicnaanaysaa iska caabinteeda saliidaha kaarboonka.Hoosta waxa ku jira ACN ayaa ka sii fiicnaan doonta dabacsanaanteeda codsiyada heerkulka hooseeya.Nitrile dhexdhexaad ah, sidaas darteed, aadka loo cayimay sababtoo ah isku dheelitirnaanta guud ee wanaagsan ee codsiyada badankooda.Caadi ahaan, nitriles waa la isku dari karaa si ay uga shaqeeyaan heerkul u dhexeeya -35 ° C ilaa +120 ° C waxayna ka sarreeyaan elastomeriyeyaasha intooda badan marka loo eego dejinta isku-buuqa, jeexjeexyada iyo caabbinta naaska.

Xirmada iyo Bixinta
Codsiga Alaabta
Acrylonitrile waxaa soo saara ganacsi ahaan propylene ammoxidation, kaas oo propylene, ammonia, iyo hawada ay ka falceliyaan kicinta sariirta dareeraha ah.Acrylonitrile waxaa loo isticmaalaa ugu horrayn sidii co-monomer-ka soo saarista fiilooyinka acrylic iyo modacrylic.Isticmaalka waxaa ka mid ah soo saarista balaastikada, dahaarka dusha sare, elastomers nitrile, resins barrier, iyo xabagta.Sidoo kale waa dhexdhexaad kiimikaad ah oo ka mid ah soo saarista antioxidants kala duwan, daawooyinka, dheeha, iyo korka-firfircoon.
1. Acrylonitrile oo laga sameeyay fiber polyacrylonitrile, oo ah fiber acrylic.
2. Acrylonitrile iyo butadiene waa la koobiymeraysan karaa si loo soo saaro caag nitrile ah.
3. Acrylonitrile, butadiene, styrene copolymerized si loo diyaariyo xabagta ABS.
4. Acrylonitrile hydrolysis waxay soo saari kartaa acrylamide, acrylic acid iyo ester-keeda.
