Usage
Imwe yemashandisirwo makuru eacrylonitrile kugadzirwa kwepolyacrylonitrile, inogoneka yepolymer ine yakanakisa kugadzikana kwemafuta uye kusagadzikana kwemakemikari.Iyi polymer inoshandiswa zvakanyanya muindasitiri yemachira kugadzira zvipfeko zvepamusoro-soro uye machira anogona kumira nemamiriro ekunze akaomarara.Pamusoro pezvo, acrylonitrile chinhu chakakosha chekuvaka mukugadzira nitrile rabha, iyo inozivikanwa nekunaka kwayo kwemafuta nemakemikari kuramba.Izvi zvinoita kuti ive sarudzo yakakurumbira yekugadzirwa kwegurovhosi, zvisimbiso uye magasi anoshandiswa mumotokari, hutano hwehutano uye petroleum maindasitiri.
Acrylonitrile inoitawo basa rakakosha mukugadzirwa kwedhayi uye resins yekugadzira.Chimiro chayo chemakemikari chinogona kushandiswa kugadzira madhayi ane simba uye anogara kwenguva refu ekushandisa kubva kumachira kusvika pakudhinda ingi.Uyezve, kushandiswa kwayo mumasikisi ekugadzira kunogonesa kuvandudzwa kwezvinhu zvinogara uye zvisingaremi zvekuvaka, fenicha uye maindasitiri emotokari.Unhu uhwu hunoita kuti acrylonitrile ive komisheni yakakosha pakugadzira zvigadzirwa zvinoda zvese simba uye aesthetics.
Pamusoro pekushandiswa kwayo mukugadzira, acrylonitrile inoshandiswawo muindasitiri yemishonga.Ndiyo chivako chemishonga yakasiyana-siyana, kusanganisira mishonga inorwisa mabhakitiriya, antihistamines uye mishonga yekenza.Kugona kwayo kuita pamwe nemamwe makomisheni inobvumira kuumbwa kwemamorekuru akaoma ane maitiro ekurapa.Izvi zvinosimbisa kukosha kweacrylonitrile munharaunda yezvokurapa, kubatsira mukugadzirwa kwemishonga inoponesa upenyu.
Mukupedzisa, acrylonitrile inhengo inokosha yakashandura maindasitiri akasiyana-siyana.Pasinei nekupisa kwayo uye njodzi dzinogona kuitika, kushandiswa kwayo mukugadzirwa kwepolyacrylonitrile, nitrile rabha, madhayi, masynthetic resin, uye mishonga inoita kuti ive chikamu chakakosha chekugadzirwa kwemazuva ano.Kunyangwe kugadzira machira epamusoro-soro, akasimba ekugadzira kana mishonga inoponesa hupenyu, acrylonitrile inoita basa rakakosha mukuumba nyika yatiri kurarama nhasi.
