Acrylonitrile bakeng sa NBR
Acrylonitrile bakeng sa NBR,
Acrylonitrile Bakeng sa Rabara ea Nitrile,
Nitrile (eo hangata e bitsoang buna-N rabara kapa perbunan) ke elastomer e sebelisoang haholo indastering ea tiiso.Nitrile ke copolymer ea li-monomers tse peli: acrylonitrile (ACN) le butadiene.Thepa ea metsoako ena ea rabara e khethoa ke litaba tsa eona tsa ACN, tse arotsoeng ka lihlopha tse tharo:
nitrile e phahameng> 45% ea litaba tsa ACN,
Nitrile e mahareng 30-45% litaba tsa ACN,
Nitrile e tlase <30% ACN content.
Ha litaba tsa ACN li phahame, li etsa hore e be betere ho hanyetsa oli ea hydrocarbon.Ha litaba tsa ACN li tlase li etsa hore e be bonolo haholoanyane lits'ebetsong tsa mocheso o tlase.Ka hona, nitrile e mahareng e hlalositsoe haholo ka lebaka la ho leka-lekana ha eona ka kakaretso lits'ebetsong tse ngata.Ka tloaelo, li-nitriles li ka kopanngoa hore li sebetse ho feta mocheso oa -35 ° C ho ea + 120 ° C 'me li phahametse li-elastomer tse ngata mabapi le ho hatella, ho taboha le ho hanyetsa ho senya.

Sesebelisoa sa Sehlahisoa
Acrylonitrile e hlahisoa khoebong ka propylene ammoxidation, eo ho eona propylene, ammonia, le moea li tšoaroang ke catalyst betheng e nang le metsi.Acrylonitrile e sebelisoa haholo-holo e le co-monomer ha ho etsoa li-acrylic le modacrylic fibers.Litšebeliso li kenyelletsa tlhahiso ea li-plastiki, li-coatings, li-elastomer tsa nitrile, li-resin tse thibelang, le li-adhesives.Hape ke lik'hemik'hale tse lipakeng tsa motsoako oa li-antioxidants tse fapaneng, meriana, lidae le tse sebetsang ka holim'a metsi.
1. Acrylonitrile e entsoeng ka fiber polyacrylonitrile, e leng fiber ea acrylic.
2. Acrylonitrile le butadiene li ka etsoa copolymerized ho hlahisa rabara ea nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized ho lokisetsa ABS resin.
4. Acrylonitrile hydrolysis e ka hlahisa acrylamide, acrylic acid le esters ea eona.
