Ngo-2015, umqambi uCui Weihua wachaza i-patent: indlela yokulungiselela ukukhanya okuphezulu kwe-calcium carbonate kwi-slag yensimbi.Ngaba kunokwenzeka ukwenza i-high-purity calcium carbonate kwi-steel slag usebenzisa slag yentsimbi ilitye lokusila elithe nkqo?

Ngokutsho kwe-China Powder Technology Network, kutshanje, "i-100000 ton carbonization method yentsimbi kunye ne-steel slag comprehensive utilization industrialization line", iprojekthi yekhontrakthi "yokuvuselela iMongolia ngesayensi kunye neteknoloji", yasungulwa eBaotou.Le projekthi yakhiwa ngokudibeneyo yi-Baotou Steel Group kunye neYukuang Environmental Protection Technology (Shanghai) Co., Ltd. Kuxelwe ukuba le projekthi isekelwe kwiziphumo ze "10,000 toni yokuvelisa umgca wokuvelisa usetyenziso olubanzi lwe-slag yensimbi ngendlela ye-carbonization. ”.I-slag yensimbi i-carbonized comprehensively, kwaye ekugqibeleni ivelisa iimveliso ze-industrial ezifana ne-high-purity calcium carbonate kunye ne-iron equkethe izinto, ukuze kuqatshelwe ukusetyenziswa kwakhona kobutyebi be-slag yensimbi.Xa kuthelekiswa nobuchwepheshe bemveli, i-carbonization iron kunye ne-steel slag iteknoloji yonyango inokuthatha ngokuthe ngqo i-carbon dioxide njengento ekrwada ukuba ithathe inxaxheba ekuphenduleni ngelixa inciphisa ukukhutshwa kwe-carbon dioxide, enempembelelo yokunciphisa i-carbon dioxide, ukufezekisa injongo yokunciphisa i-greenhouse. ukukhutshwa kwegesi kunye nokukhuthaza uphuhliso lwesetyhula ephantsi kwekhabhoni.Emva kokugqitywa kweprojekthi, iitoni ze-424000 ze-slag zensimbi zingaphathwa minyaka yonke, ngelixa malunga neetoni ze-100000 ze-carbon dioxide zingafakwa (itywinwe), kunye nomthamo wokuvelisa i-200000 yeetoni ze-high-purity calcium carbonate kunye ne-310000 yeetoni zentsimbi. izinto eziphathekayo zinokufezekiswa.Le projekthi luvavanyo olongezelelekileyo lwemizi-mveliso, olunokukhuthazwa ngokubanzi kumashishini afanayo.Ngelixa uhlangabezana nemfuno yokusetyenziswa okubanzi kwenkunkuma eqinileyo, kuyanceda ekufezekiseni injongo yencopho yekhabhoni kunye ne-carbon neutralization.Oku kuthetha ukuba nokwenzeka kweprojekthi yokuvelisa i-high-purity calcium carbonate kwi-steel slag.Ikwabonelela ngendlela entsha yokusetyenziswa ngokubanzi kwenkunkuma eqinileyo ye-steel slag.

Iimpawu eziphambili zezobugcisa zokuvelisa i-high-purity calcium carbonate kwi-steel slag yilezi zilandelayo: okokuqala, gaya i-slag yensimbi ibe ngumgubo, uveze i-calcium oxide yamahhala kwi-slag yensimbi ukuya kumphezulu we-slag yensimbi, ukhuphe i-calcium oxide insimbi slag ngendlela emanzi kunye 0.5% acetic acid, ihluzo kwaye acacise, ngoko carbonize ngayo ngegesi carbon dioxide, kwaye emva koko dehydrate, hlamba, yomile, epholile, phula kwaye ikhusi ukuvelisa ukukhanya okuphezulu kwe-calcium carbonate.Ukucoceka okuphezulu kwe-calcium carbonate kusetyenziswa ngokubanzi njengokuzaliswa kweethayile zomgangatho owenziweyo, irabha, iiplastiki, ukwenza iphepha, iipeyinti, iipeyinti, i-inki, iintambo, izixhobo zokwakha, ukutya, amayeza, amalaphu, ukutya, intlama yamazinyo kunye nezinye iimveliso.Kule nkqubo, i-fineness yokugaya i-slag yensimbi idinga ukufikelela kwii-meshes ezingaphezu kwama-400.Luhlobo luni lwezixhobo ezinokusetyenziswa ukuphumeza imveliso enkulu ye-steel slag micro powder?Njengomvelisi oqeqeshiweyo weintsimbiilitye lokusila i-slag, HCMilling(Guilin Hongcheng) icebisa ukuba ukhetheHLM intsimbi slagilitye lokusila elithe nkqo ukuvelisa i-steel slag powder.Okwangoku, inkqubo yonyango yentsimbi ye-slag powder kwimarike ikakhulu i-pre grinding + fine grinding.I-slag yensimbi inokugaywa ukuya kuma-microns angaphezu kwama-420 emva kokugaya amanqanaba amabini.Ixabiso lezixhobo, indawo yomgangatho kunye nokusetyenziswa kwamandla okuphakathi lutyalo-mali olukhulu.

Iqela le-R&D le-HCMilling(Guilin Hongcheng) kunye neengcali zoshishino, ngokusebenzisana novavanyo olunzulu, lisunguleHLM series steel slagilitye lokusila elithe nkqo, enokugaya i-steel slag powder ibe yimo ngexesha elinye, iphucula kakhulu ixabiso lokusetyenziswa kwe-steel slag powder, kunye nokuvula imarike yesicelo esisezantsi.Yisixhobo esifanelekileyo se-steel slag micro powder ukugcina iindleko, ukusetyenziswa kwamandla, indawo yomgangatho, isivuno kunye nexabiso elongezelelweyo leemveliso ezigqityiweyo.

Ukuba unemfuno yokuveliswa kwe-slag powder kunye nokulungiswa, nceda uqhagamshelane nathi ngeenkcukacha kwaye unikezele ngolwazi olulandelayo kuthi:
