Yiziphi izimboni i-acrylonitrile esetshenziswa kakhulu?

I-Acrylonitrile yenziwe nge-propylene ne-ammonia njengezinto zokusetshenziswa ngokusabela kwe-oxidation kanye nenqubo yokucwenga.Iwuhlobo lwenhlanganisela yezinto eziphilayo, ifomula yamakhemikhali i-C3H3N, iwuketshezi olungenambala olunephunga elivuthayo, oluvuthayo, umhwamuko walo nomoya kungakha ingxube eqhumayo, uma kuba nomlilo ovulekile, ukushisa okuphezulu kulula ukubangela ukuvutha, nokukhulula amagesi anobuthi. , nama-oxidants, ama-asidi aqinile, izisekelo eziqinile, ama-amine, ukusabela kwe-bromine.

Isetshenziswa kakhulu njengempahla eluhlaza ye-acrylic fiber kanye ne-ABS/SAN resin.Ngaphezu kwalokho, isetshenziswa kabanzi ekukhiqizeni i-acrylamide, unamathisele kanye ne-adiponitrile, irabha yokwenziwa, iLatex, njll.

Izicelo zemakethe ye-Acrylonitrile

I-Acrylonitrile iyinto ebalulekile yokusetshenziswa kwezinto ezintathu zokwenziwa (ipulasitiki, irabha yokwenziwa, i-synthetic fiber).Ukusetshenziswa kwe-acrylonitrile engezansi komfula kugxile emikhakheni emithathu ye-ABS, i-acrylic ne-acrylamide, ebalele ngaphezu kuka-80% wengqikithi yokusetshenziswa kwe-acrylonitrile.Eminyakeni yamuva nje, ngokuthuthukiswa kwemishini yasendlini kanye nezimboni zezimoto, i-China isibe enye yemakethe ye-acrylonitrile ekhula ngokushesha kakhulu emhlabeni.Imikhiqizo ye-downstream isetshenziswa kakhulu ezintweni zasendlini, izingubo zokugqoka, izimoto, imithi kanye nezinye izindawo zomnotho wezwe.

I-Acrylonitrile ikhiqizwa ukusabela kwe-oxidation kanye nenqubo yokucwenga ye-propylene namanzi e-ammonia.Isetshenziswa kabanzi ekukhiqizeni imboni ye-resin ne-acrylic fiber.I-Carbon fiber inkambu yesicelo ngokukhula okusheshayo kwesidingo esikhathini esizayo.

Njengolunye lwezinhlelo zokusebenza ezibalulekile ezansi nomfula we-acrylonitrile, i-carbon fibre yinto entsha ecwaningwa kakhulu futhi yathuthukiswa eShayina.I-Carbon fiber isiyingxenye ebalulekile yezinto ezingasindi, futhi kancane kancane kusukela ezintweni zensimbi ezedlule, isiphenduke into eyisisekelo yokusetshenziswa emkhakheni wezomphakathi kanye nezempi.

Ngokuthuthuka okuqhubekayo komnotho wezwe lethu, isidingo se-carbon fiber nezinto eziyinhlanganisela siyakhula.Ngokwezibalo ezifanele, isidingo saseChina se-carbon fiber sifinyelele amathani angama-48,800 ngo-2020, okuwukunyuka kwama-29% uma kuqhathaniswa no-2019.

Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, imakethe ye-acrylonitrile ikhombisa umkhuba omuhle wokuthuthuka:

Enye i-propane njengomugqa wokukhiqiza we-acrylonitrile ekuthuthukisweni kancane kancane;

Okwesibili, ucwaningo lwama-catalysts amasha kuseyisihloko socwaningo lwezazi zasekhaya nezangaphandle;

Okwesithathu, idivayisi enkulu;

Okwesine, ukonga amandla kanye nokunciphisa ukungcola, ukuthuthukiswa kwenqubo kubaluleke kakhulu;

Okwesihlanu, ukwelashwa kwamanzi angcolile sekube wucwaningo olubalulekile.
