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 kweChina 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 yakhiwe ngokudibeneyo yi-Baotou Steel Group kunye neYukuang Environmental Protection Technology (Shanghai) Co., Ltd. Kuxelwe ukuba le projekthi isekelwe kwiziphumo ze "10,000 ton verification line production for comprehensive of steel slag by carbonization method". 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 bendabuko, 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, ukuphumeza injongo yokunciphisa ukukhutshwa kwegesi ye-greenhouse kunye nokukhuthaza ukuphuhliswa kwe-circular low-carbon. Emva kokugqitywa kweprojekthi, iitoni ze-424000 ze-slag zensimbi zinokuphathwa minyaka yonke, ngelixa malunga neetoni ze-100000 ze-carbon dioxide zingafakwa i-carbonized (itywinwe), kunye nomthamo wokuvelisa i-200000 yeetoni ze-high-purity calcium carbonate kunye ne-310000 yeetoni zezinto zensimbi zinokufumaneka. 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 zobuchwephesha bokuvelisa i-high-purity calcium carbonate kwi-slag yensimbi zezi zilandelayo: okokuqala, gaya i-slag yensimbi ibe ngumgubo, utyhile i-calcium oxide yamahhala kwi-slag yentsimbi ukuya kumphezulu we-slag yensimbi, ukhuphe i-calcium oxide kwi-slag yensimbi ngendlela emanzi kunye ne-0.5% ye-acetic acid, i-acetic acid, ihluzo kwaye icacise, emva koko i-carbonize kunye ne-carbon desh, i-dioksidi eyomileyo, ikhusi kunye ne-carbon dioxide eyomileyo, epholile 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:
