Ngawaphi amashishini asetyenziswa kakhulu iacrylonitrile?

I-Acrylonitrile yenziwe ngepropylene kunye ne-ammonia njengezinto eziluhlaza ngokusabela kwe-oxidation kunye nenkqubo yokucoca.Ngaba luhlobo lwe-organic compound, i-chemical formula yi-C3H3N, lulwelo olungenambala olunevumba elitshisayo, elivuthayo, umphunga walo kunye nomoya unokwenza umxube oqhumayo, kwimeko yomlilo ovulekileyo, ukushisa okuphezulu kulula ukubangela ukutsha, kunye nokukhupha iigesi ezinobuthi. , kunye ne-oxidants, i-acids eqinile, iziseko ezinamandla, i-amines, i-bromine reaction.

Isetyenziswa kakhulu njengento ekrwada yefiber ye-acrylic kunye ne-ABS/SAN resin.Ukongeza, isetyenziswa ngokubanzi kwimveliso ye-acrylamide, i-paste kunye ne-adiponitrile, irabha yokwenziwa, iLatex, njl.

izicelo zemarike Acrylonitrile

I-Acrylonitrile yinto ebalulekileyo ekrwada yezinto ezintathu zokwenziwa (iplastiki, i-rubber yokwenziwa, i-synthetic fiber).Ukusetyenziswa kwezantsi kwe-acrylonitrile kugxininiswe kwiinkalo ezintathu ze-ABS, i-acrylic kunye ne-acrylamide, eyenze ngaphezu kwe-80% yokusetyenziswa ngokupheleleyo kwe-acrylonitrile.Kwiminyaka yakutshanje, ngophuhliso lwezixhobo zasekhaya kunye nemizi-mveliso yeemoto, i-China iye yaba yenye yezona zinto zikhula ngokukhawuleza ukusetyenziswa kweemarike ze-acrylonitrile.Iimveliso ezisezantsi zisetyenziswa kakhulu kwizixhobo zendlu, iimpahla, iimoto, amayeza kunye nezinye iindawo zoqoqosho lwelizwe.

I-Acrylonitrile yenziwa nge-oxidation reaction kunye nenkqubo yokucocwa kwepropylene kunye namanzi e-ammonia.Isetyenziswa ngokubanzi kwimveliso ye-resin kunye ne-acrylic fiber industry.Ifayibha yeCarbon yintsimi yesicelo ngokukhula okukhawulezayo kwemfuno kwixesha elizayo.

Njengomnye wezicelo ezibalulekileyo ezisezantsi ze-acrylonitrile, i-carbon fiber yinto entsha ephandwayo kwaye iphuhliswe e-China.Ifayibha yeCarbon ibe yinxalenye ebalulekileyo yemathiriyeli ekhaphukhaphu, kwaye ngokuthe ngcembe ukusuka kwizinto ezidlulileyo zetsimbi, iye yaba yeyona nto iphambili yesicelo kwintsimi yoluntu neyomkhosi.

Ngokuqhubekayo kophuhliso loqoqosho olukhawulezayo lwelizwe lethu, imfuno ye-carbon fiber kunye nemathiriyeli yayo edibeneyo iyanda.Ngokwezibalo ezifanelekileyo, imfuno yaseTshayina ye-carbon fiber ifikelele kwiitoni ezingama-48,800 ngo-2020, ukonyuka kwe-29% xa kuthelekiswa no-2019.

Ngophuhliso oluqhubekayo lwesayensi kunye nethekhnoloji, imarike ye-acrylonitrile ibonisa umzila omkhulu wophuhliso:

Enye ipropane njengomgca wemveliso we-acrylonitrile ekunyuseni ngokuthe ngcembe;

Okwesibini, uphando lwee-catalysts ezintsha lusesihloko sophando lwabaphengululi basekhaya nabangaphandle;

Okwesithathu, isixhobo esikhulu;

Okwesine, ukonga amandla kunye nokunciphisa ukukhutshwa, ukuphuculwa kwenkqubo kubaluleke kakhulu;

Okwesihlanu, ukucocwa kwamanzi amdaka kuye kwaba ngumxholo obalulekileyo wophando.
