Iphakheji Nokulethwa
Isicelo somkhiqizo
I-Acrylonitrile ikhiqizwa ukuthengisa nge-propylene ammoxidation, lapho i-propylene, i-ammonia, nomoya kusabela nge-catalyst embhedeni omanzi.I-Acrylonitrile isetshenziswa ngokuyinhloko njenge-co-monomer ekukhiqizeni imicu ye-acrylic ne-modacrylic.Izinto ezisetshenziswayo zihlanganisa ukukhiqizwa kwamapulasitiki, okokugcotshwa okungaphezulu, ama-nitrile elastomers, ama-barrier resins, nama-adhesives.Iphinde ibe yikhemikhali emaphakathi ekuhlanganisweni kwama-antioxidants ahlukahlukene, amakhemisi, odayi, kanye ne-surface-active.
1. I-Acrylonitrile eyenziwe nge-polyacrylonitrile fiber, okuyi-acrylic fiber.
2. I-Acrylonitrile ne-butadiene ingenziwa i-copolymerized ukuze ikhiqize irabha ye-nitrile.
3. I-Acrylonitrile, butadiene, styrene copolymerized ukulungiselela i-ABS resin.
4. I-Acrylonitrile hydrolysis ingakhiqiza i-acrylamide, i-acrylic acid nama-esters ayo.
Iningi le-carbon fiber emhlabeni lisuselwa ku-PAN eyenziwe kusetshenziswa i-ACN monomer ye-propylene ne-ammonia.I-ACN yenziwe i-polymerized ibe yi-PAN ngokuyihlanganisa nama-comonomers enziwe ngepulasitiki ne-catalyst.Yonke le nqubo yokukhiqiza amakhemikhali kanye nokuguqulwa iyinkimbinkimbi, iyabiza futhi idinga amandla.Ngaphezu kwalokho, ukukhiqiza ikhilogremu engu-1 ye-carbon fibre kudinga amakhilogremu angu-2 we-PAN, okunikeza i-PAN izinga lokuguqulwa elingu-50% nje - kanye nendawo enkulu uma kuqhathaniswa negesi ebamba ukushisa.
