Calcium carbide slag jẹ iyọkuro egbin ni akọkọ ti o jẹ ti kalisiomu hydroxide lẹhin hydrolysis ti kalisiomu carbide lati gba gaasi acetylene.Igbaradi ti awọn ọja kemikali lati slag carbide jẹ fun idi ti atunlo awọn orisun, ati idagbasoke awọn ilana alawọ ewe ati idinku awọn idiyele imọ-ẹrọ yoo jẹ idojukọ ti iwadii iwaju.HCMilling (Guilin Hongcheng) jẹ olupese tikalisiomu hydroxideslakingatikalisiomukaboneti lilọ ọlọohun elo.Awọn atẹle yoo ṣafihan ọ si ilana ti ngbaradi nano calcium carbonate lati slag carbide.
Nano-calcium carbonate jẹ lilo pupọ ni roba, awọn pilasitik, ṣiṣe iwe, inki ati awọn aaye miiran, pẹlu agbara ọja nla.Ninu ile-iṣẹ, ọna carbonization ni a lo ni akọkọ lati gbejade kaboneti nano-calcium, ati pe CaO ni a gba nipasẹ didẹ okuta oniyebiye, eyiti o digested ati daduro Ca (OH) 2 Crush, ṣafikun aṣoju iṣakoso fọọmu gara, kọja CO2 carbonization, gbígbẹ, ati dada itọju lati gba nano-calcium carbonate.Lakoko ilana yii, gaasi egbin (CO2), omi egbin (omi funfun) ati aloku egbin yoo jẹ ipilẹṣẹ, eyiti yoo ja si idinku ninu didara ọja ati dinku tabi mọ awọn egbin mẹta ti itujade Zero ati imudarasi didara nano-calcium carbonate jẹ awọn ọran pataki, ati slag carbide jẹ patapata ni ila pẹlu ero aabo ayika ti atọju egbin pẹlu egbin.
Lọwọlọwọ, igbaradi ti nano-calcium carbonate lati calcium carbide slag ni akọkọ pẹlu awọn ọna mẹta: calcination slaking, hydrochloric acid leaching ati ammonium kiloraidi leaching.Li Rui et al.lo ọna ilana ti calcination ati slaking titẹ lati jẹ ki kalisiomu carbide slag fesi pẹlu CO2 flue gaasi ni a pressurized carbonization riakito lati gba iyipo nano kalisiomu kaboneti (60nm).Ilana yii kii ṣe ipinnu idoti ti gaasi egbin CO2 nikan, ṣugbọn tun gba awọn ọja ti o ni iye to gaju;Liu Fei et al.gba ilana jijẹ hydrochloric acid, acidified calcium carbide slag pẹlu hydrochloric acid pẹlu pH=8, o si ṣe iṣesi metathesis pẹlu iṣuu soda kaboneti.Awọn esi ti fihan pe awọn acidified kalisiomu carbide slag yoo se igbelaruge kalisiomu kaboneti whiskers Awọn iṣẹlẹ ti agglomeration ati isokuso forked ẹka bajẹ nyorisi aragonic kalisiomu kaboneti whiskers pẹlu aṣọ pinpin ati ki o ga aspect ratio (30-60).Ti a ṣe afiwe pẹlu awọn ohun elo aise ti o ga-mimọ, o rii pe nano-carbonic acid ti a pese sile lati inu calcium carbide slag Awọn kalisiomu pade boṣewa orilẹ-ede ati mu idoti ti o ṣẹlẹ nipasẹ slag carbide.Ilana yii ṣe imọran ipa ọna ilana ti o munadoko fun igbaradi ti nano-calcium carbonate.
Zhu Min ati awọn miiran lo ammonium kiloraidi lati ṣaju slag carbide calcium, ati lẹhinna pese kaboneti nano-calcium nipasẹ carbonization.Awọn abajade fihan pe nigbati ifọkansi ti ammonium kiloraidi ojutu jẹ 8%, iwọn lilo ti slag carbide calcium ti ju 92%.Iru kaboneti nano-calcium (iwọn patiku apapọ jẹ 38nm), mimọ ati funfun ti ọja ti o gba nipasẹ ilana yii jẹ to 99.65% ati 98.60% lẹsẹsẹ, eyiti o yanju iṣoro ti mimọ kekere ati funfun ti ko dara ti o fa nipasẹ awọn aimọ si nano- kalisiomu kaboneti, ati pe o jẹ ojutu ti o dara fun awọn ohun elo ile-iṣẹ ti o tẹle A pese ipa ọna ilana to dara.
Ni akojọpọ, iye nla ti CO2 ni a lo ni igbaradi ti slag calcium carbonate slag, ati lilo iye-iye ti o ga julọ ti slag carbide calcium le ṣee ṣe ni akoko kanna.Bibẹẹkọ, o rọrun lati ṣe agbejade omi idọti nigbati ilẹ ti yipada nipasẹ awọn afikun kemikali.Ti a ko ba tọju rẹ, yoo fa idoti keji.Awọn ibeere atẹle Siwaju ni imọran okeerẹ ni a fun si awọn ọja-ọja ti iṣesi lati mọ atunlo ti slag carbide.
