Acrylonitrile ee NBR
Acrylonitrile ee NBR,
Acrylonitrile oo loogu talagalay NBR Nitrile,
NBR (Nitrile), kiimiko ahaan, waa copolymer of butadiene iyo acrylonitrile.Maadada Acrylonitrile waxay ku kala duwan tahay badeecadaha ganacsiga min 18% ilaa 50%.Marka maaddada NBR ay korodho, iska caabinta saliidaha saldhigga batroolka iyo shidaalka kaarboon-carbon ayaa kordha, laakiin dabacsanaanta heerkulka hooseeya ayaa hoos u dhacaya.
Ku saabsan NBR
Sababtoo ah iska caabbinta aadka u fiican ee alaabta batroolka, iyo awoodda ay u leedahay in lagu daro adeegga heerkulka u dhexeeya -35 ° C ilaa +120 ° C (-30 ° F ilaa + 250 ° F), Nitrile / NBR waa tan ugu ballaaran. elastomer loo isticmaalo warshadaha shaabadda maanta.Sidoo kale qaar badan oo ka mid ah tilmaamo caag militari oo loogu talagalay shidaalka iyo O-rings-yada u adkeysanaya saliidda waxay u baahan yihiin xeryahooda nitrile ku saleysan.
Waa in la sheegaa in si loo helo iska caabin wanaagsan heerkulka hooseeya, inta badan waa lagama maarmaan in la bixiyo qaar ka mid ah caabbinta heerkulka sare.Xeryahooda Nitrile waxay ka sarreeyaan elastomeriyeyaasha intooda badan marka loo eego isku-buufinta, jeexista, iyo caabbinta nabarka.Xeryahooda Nitrile ma laha iska caabin wanaagsan oo ozone, iftiinka qoraxda, ama cimilada.Waa in aan lagu kaydin meel u dhow matoorada korontada ama qalabka kale ee soonka ee ozone.

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.
