I-Kaolin, ngakumbi i-kaolin ecolekileyo kakhulu, njengesixhobo esibaluleke kakhulu esingeyo-metallic esingaphiliyo, ibisoloko idlala indima ebaluleke kakhulu kushishino lwephepha ngeempawu zayo ezibonakalayo ezintle. I-kaolin ecoliweyo esetyenziswa kushishino lwephepha sisixhobo esisebenzayo solwakhiwo esineembobo kwaye simhlophe kakhulu, esisetyenziswa kakhulu endaweni ye-titanium dioxide ebiza kakhulu kunye nezinye iipigment ezikumgangatho ophezulu. Njengomvelisi wezixhobo zokugaya,i-kaolin ene-calciumnkqo ecolekileyo kakhuluirolaumsilo iveliswe yi-HCMilling (Guilin Hongcheng) isetyenziswa kakhulu kwaye yamkelwe ekuveliseni i-kaolin ene-calcium. Oku kulandelayo kukwazisa indlela yokuvelisa i-kaolin ene-calcium:

Iimfuno zomgangatho weshishini lephepha le-kaolin e-calcined ziboniswa kakhulu kwiimfuno zobungakanani besuntswana, ubumhlophe, amandla okufihla, ukufunxwa kweoyile, uxinzelelo lwe-viscosity, ixabiso le-pH, ixabiso lokuguguleka kunye nezinye izalathisi ze-kaolin e-calcined. Phantsi kweemeko apho imakethi ye-kaolin eqhelekileyo ehlanjiweyo ibincipha unyaka nonyaka ngenxa yempembelelo ye-calcium carbonate enzima, intengiso yemarike ibikhula, nto leyo eye yenza abavelisi abaninzi balandela. Ukususela ngeminyaka yoo-1980, inani elikhulu le-kaolin yochungechunge lwamalahle lifunyenwe (kuthiwa iindawo ezigciniweyo ezinokubakho zidlula iitoni ezili-10 zeebhiliyoni). Ngenxa yomgangatho wayo ophezulu kunye nokungcola okuncinci okunobungozi, i-kaolin yochungechunge lwamalahle ibe yinto efanelekileyo yokwenza i-kaolin yodidi lwephepha. Ithemba lemakethi ye-kaolin e-calcined eveliswe kwi-kaolin yochungechunge lwamalahle libanzi.

Inkqubo yokuvelisa i-kaolin ene-calcium ibandakanya ikakhulu amacandelo amabini: inkqubo yokutyumza i-superfine kunye nenkqubo yokwenza i-calcin ibe mhlophe.

1. Inkqubo yokusila i-superfine yendlela yokuvelisa i-kaolin e-calcined: inkqubo yokusila i-superfine likhonkco elibalulekileyo lokumisela umgangatho we-kaolin. Ukutyunyuzwa kwe-kaolin series yamalahle yi-kaolin eqinileyo (ukusuka kwi-5~20mm ukuya kwi-40~80 μ m) I-Ultrafine (ukusuka kwi-40 ukuya kwi-80 μ M ukuya kwi-10 μ M okanye - 2 μ m).i-kaolin ene-calciumI-Raymond mill kunye ne-calcined kaolin vertical roller mill eziveliswe yi-HCMilling (Guilin Hongcheng) zizixhobo zokutyumza ezirhabaxa, ezinokusetyenziselwa ukutyumza okurhabaxa kwendlela yokuvelisa i-calcined kaolin, kwaye zinokucubungula i-kaolin yamalahle e-80-600 mesh;uthotho lwe-HLMX olune-calcined kaolin nkqo ecolekileyo kakhuluirolaumsilo, i-ring roller mill kunye nezinye izixhobo zokutyumza ezicolekileyo kakhulu zifanelekile ekutyumzeni okucolekileyo kakhulu kwindlela yokuvelisa i-calcined kaolin, enokucubungula i-3-45 μ M. Umgubo we-kaolin ocolekileyo kakhulu yi-calcined kaolin superfine powder mill efanelekileyo.

2. Inkqubo yokubala kunye nokwenza mhlophe indlela yokuvelisa i-kaolin ene-calcium: Ngenxa yeempawu ze-diagenetic ze-kaolin yochungechunge lwamalahle, oko kukuthi, iqulethe izinto eziphilayo, ngoko ke ubumhlophe bayo obungavuthwanga buyi-6 ~ 40% kuphela, nto leyo ekude kakhulu ekuhlangabezaneni neemfuno zomgangatho weshishini lephepha le-kaolin egqunywe nge-calcium, ngoko ke inkqubo yokususa i-calcium kunye nokwenza mhlophe kufuneka yamkelwe. Ngokweemfuno ezahlukeneyo zomgangatho we-kaolin, inokwahlulwahlulwa ibe ziimveliso ezimbini: i-kaolin ene-calcium enobushushu obuphakathi kunye ne-kaolin ene-calcium enobushushu obuphezulu.

Uthelekiso lwenkqubo yeendlela zokuvelisa i-kaolin ene-calcium: ngokwenkqubo yokuba inkqubo ye-superfine yinkqubo emanzi okanye eyomileyo kunye nolandelelwano lwenkqubo ye-superfine kunye nenkqubo ye-calcination, iinkqubo ezine zemveliso zinokudityaniswa, oko kukuthi

(1) inkqubo ye-wet superfine elandelwa yinkqubo ye-calcination (2) inkqubo ye-dry superfine elandelwa yinkqubo ye-calcination (3) i-calcination elandelwa yinkqubo ye-wet superfine (4) i-calcination elandelwa yinkqubo ye-dry superfine. Ngenxa yokuba abantu banokuqonda okwahlukileyo ngezinto ezicolekileyo kakhulu, iindlela zenkqubo ezisetyenziswa kumashishini ahlukeneyo zahlukile:

(1) Inkqubo yokubala i-wet superfine inde kakhulu, kodwa iyakwazi ukuziqhelanisa nezinto ezikrwada, kwaye umgangatho wemveliso unokuhlangabezana neemfuno zoshishino lwephepha;

(2) Inkqubo yokulungisa i-calcination kunye nokumanzisa kwakhona i-superfine ngokubanzi ifuna izixhobo ezizodwa zokomisa kunye nezixhobo zokusasaza. Le nkqubo ayinakukwazi ukulungelelanisa izinto eziluhlaza, kodwa inokuvelisa iimveliso ezifunekayo kushishino lwephepha;

(3) Inkqubo ye-dry superfine calcination kunye ne-calcination yokuqala kunye ne-dry superfine process azikwazi ukuvelisa i-kaolin kushishino lwephepha (ngenxa yesizathu sezixhobo ze-superfine), ezifuna umgangatho ophezulu wezinto ezikrwada.

Lilonke, inkqubo ye-dry superfine ngaphambi kokuba i-calcination isebenze kakuhle, kwaye umzobo wokuhamba kwenkqubo ngulo: i-ore eluhlaza → ukutyumza → ukutyumza → i-dry superfine → i-calcination → imveliso. Iingenelo zale nkqubo zezi: (1) inkqubo imfutshane, kwaye yonke inkqubo ifuna izixhobo eziphambili ezintathu ukuya kwezine kuphela. Ukuba uHongchengI-HLMX calcined kaolin ultrafine powder mill Kukhethwa izixhobo ezintathu kuphela ezifunekayo, ezizezi, i-crusher, i-calcined kaolin ultrafine powder mill, i-calciner, efanelekileyo kulawulo olupheleleyo kunye nokucwangcisa ngokufanelekileyo; (2) Ukusetyenziswa kwamandla kufanelekile. Kule nkqubo, inkqubo ye-superfine yezinto ibekwa ngaphambi kwenkqubo ye-calcination ukuze kuthintelwe ingxaki yokusebenzisa amandla amaninzi ngenxa yokutyumza nokutsha kwezinto. Ukuba inkqubo ye-powder calcination iyamkelwa, inokuthathwa njengenkqubo yemveliso eyomileyo epheleleyo. Ngokuphathelele ubuchwepheshe, ukusetyenziswa kwamandla kufanelekile ngakumbi.

Ukusebenzisa i-kaolin yochungechunge lwamalahle ukuvelisa i-kaolin ene-calcium ekumgangatho wokugquma kushishino lwephepha ngokuqinisekileyo yindlela esebenzayo yokusebenzisa i-gangue yamalahle ngengqiqo. Kufuneka kuqatshelwe ukuba iindlela ezifanelekileyo zenkqubo kufuneka zikhethwe ngokwezixhobo zasekuhlaleni kunye nemali. Ukuba ufuna ukwazi ngakumbi malunga neendlela zemveliso kunye nokukhethwa kwezixhobo ze-kaolin ene-calcium, nceda usitsalele umnxeba ukuze ufumane iinkcukacha.
