Acrylonitrile ee PAN
Acrylonitrile ee PAN,
Acrylonitrile oo loogu talagalay Polyacrylonitrile, Acrylonitrile oo loogu talagalay fiber polyacrylonitrile,
Polyacrylonitrile (PAN) waa polymer synthetic ah oo leh caanaha toosan (C3H3N) n.Inkasta oo ay tahay heerkulbeeg, haddana kuma dhalaalin xaaladaha caadiga ah, maadaama ay hoos u dhacdo ka hor inta aysan dhalaalin heer ka sarreeya 300 ° C.Ku dhawaad dhammaan resins PAN waa copolymers laga sameeyay isku-dhafka monomers, oo leh acrylonitrile oo ah qaybta ugu muhiimsan.Waa polymer isku dhafan oo loo isticmaalo in lagu soo saaro noocyo kala duwan oo badeecooyin ah, oo ay ku jiraan fiilooyinka dunta, xuubabka sifaynta ultra-filtration, fiilooyinka godan ee rosiska osmosis, iwm. Fiilooyinka PAN ayaa horudhac u ah soo saarista fiilooyinka carbon tayo sare leh.

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.
