I-Acrylonitrile: Yiziphi izimboni esetshenziswa kakhulu? Liyini ikusasa le-acrylonitrile?

I-Acrylonitrile ikhiqizwa ukusabela kwe-oxidation kanye nenqubo yokucwenga kusetshenziswa i-propylene namanzi e-ammonia njengezinto zokusetshenziswa..Iwuhlobo lwezinhlanganisela eziphilayo, ifomula yamakhemikhali i-C3H3N, iwuketshezi olungenambala olubabayo, oluvutha umlilo, umhwamuko nomoya kungakha ingxube eqhumayo, uma kunomlilo ovulekile, ukushisa okuphezulu kulula ukubangela ukuvutha, nokukhulula igesi enobuthi, futhi i-oxidant, i-asidi eqinile, isisekelo esiqinile, i-amine, ukusabela kwe-bromine ngobudlova.

Isetshenziswa kakhulu njengempahla eluhlaza ye-acrylic fibre kanye ne-ABS/SAN resin. Ngaphandle kwalokho, isetshenziswa kabanzi ekukhiqizeni i-acrylamide, ama-pastes kanye ne-adiponitrile, irabha yokwenziwa, i-Latex, njll.

Aizicelo

I-Acrylonitrile yizinto ezintathu ezinkulu zokwenziwa (ipulasitiki, irabha yokwenziwa, i-synthetic fibre) impahla eluhlaza ebalulekile, ukusetshenziswa kwezwe lethu i-acrylonitrile ezansi nomfula kugxilwe ku-ABS, i-acrylic ne-acrylamide emikhakheni emithathu, i-akhawunti emithathu cishe ye-80% yokusetshenziswa okuphelele kwe-acrylonitrile. Eminyakeni yamuva nje, ngokuthuthukiswa kwemishini yasendlini kanye nezimoto, i-China ibe ngelinye lamazwe akhula ngokushesha emakethe yomhlaba wonke ye-acrylonitrile. Imikhiqizo ye-downstream isetshenziswa kakhulu ezintweni zasendlini, izingubo zokugqoka, izimoto, imithi kanye neminye imikhakha emnothweni wezwe.

I-Acrylonitrile ikhiqizwa ukusabela kwe-oxidation kanye nenqubo yokucwenga ye-propylene ne-ammonia. Isetshenziswa kabanzi ekukhiqizeni izimboni ze-resin ne-acrylic fiber. I-Carbon fiber inkambu yesicelo enesidingo sokukhula ngokushesha esikhathini esizayo.

I-Carbon fiber, njengenye yezinto ezibalulekile ezisetshenziswa ezansi nomfula i-acrylonitrile, iyinto entsha egxile ocwaningweni nasekuthuthukisweni eChina. I-Carbon fiber isiyingxenye ebalulekile yezinto ezingasindi, futhi kancane kancane kusukela ezintweni zensimbi ezedlule, emkhakheni wezomphakathi kanye nezempi isiphenduke into eyinhloko yokusetshenziswa.

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

1. I-propane njengempahla eluhlaza yomugqa wokukhiqiza we-acrylonitrile ikhuthazwa kancane kancane;
2. ucwaningo lwama-catalysts amasha kuseyisihloko socwaningo lwezazi ekhaya naphesheya;
3. idivayisi enkulu;
4. ukongiwa kwamandla kanye nokunciphisa ukungcola, ukuthuthukiswa kwenqubo kubaluleke kakhulu;
5. Ukuhlanza amanzi angcolile sekube wucwaningo olubalulekile.
