Kaolin, ingakumbi ultra-fine calcined kaolin, njengento ebaluleke kakhulu inorganic non-metallic imathiriyeli, ibisoloko idlala indima ebaluleke kakhulu kushishino iphepha kunye iimpawu zayo ezibalaseleyo emzimbeni.I-kaolin ene-calcined esetyenziswa kushishino lwephepha i-porous and white high structural functional material, esetyenziswa ikakhulu endaweni ye-titanium dioxide ebizayo kunye nezinye ii-pigments zodidi oluphezulu.Njengomvelisi wezixhobo zokusila, icalcined kaolinngokuthe nkqo kakhuluirolailitye lokusila eveliswe yi HCMilling(Guilin Hongcheng) iye yasetyenziswa ngokubanzi kwaye yamkelwa kwimveliso kaolin calcined.Oku kulandelayo kukwazisa kwindlela yokuvelisa i-kaolin ene-calcined:

Iimfuno zomgangatho weshishini lephepha le-kaolin ene-calcined ziboniswa ikakhulu kwiimfuno zobungakanani besuntswana, ubumhlophe, amandla okufihla, ukufunxa ioli, ukuxinana kwe-viscosity, ixabiso le-pH, ixabiso lokunxiba kunye nezinye izibonakaliso ze-kaolin e-calcined.Ngaphantsi kweemeko apho imarike ye-kaolin eqhelekileyo ihlanjwe iyancipha unyaka nonyaka ngenxa yempembelelo ye-calcium carbonate enzima, ukuthengiswa kweemarike kuye kwanda, okwenze ukuba abaninzi abavelisi balandele.Ukusukela ngeminyaka yee-1980s, kuye kwafunyanwa inani elikhulu le-kaolin yamalahle (kuthiwa oovimba abalindelekileyo badlula iitoni zebhiliyoni ezili-10).Ngenxa yomgangatho wayo ophezulu kunye nokungcola okumbalwa okuyingozi, uchungechunge lwamalahle lwe-kaolin lube yinto efanelekileyo ekrwada yokuvelisa ibakala lokugquma iphepha calcined kaolin.Ithemba lentengiso ye-kaolin eyenziwe nge-calcined eveliswe kuthotho lwamalahle kaolin libanzi.

Inkqubo yemveliso kaolin calcined ikakhulu ibandakanya izahlulo ezimbini: inkqubo yokutyumza superfine kunye nenkqubo calcining mhlophe.

1. Inkqubo yokugaya i-superfine yendlela yokuvelisa i-kaolin calcined: inkqubo yokugaya i-superfine likhonkco elibalulekileyo lokumisela umgangatho we-kaolin.Ukutyunyuzwa kothotho lwamalahle e-kaolin superfine yi-kaolin eqinile (ukusuka kwi-5~20mm ukuya kwi-40~80 μ m) I-Ultrafine (ukusuka kuma-40 ukuya kuma-80 μ M ukuya – 10 μ M okanye – 2 μ m).calcined kaolinRaymond lokusila kunye calcined kaolin nkqo roller lokusila eveliswe HCMilling (Guilin Hongcheng) zixhobo ezirhabaxa zokutyumza, ezinokusetyenziswa ukutyunyuzwa preliminary erhabaxa indlela imveliso kaolin calcined, kwaye kungenziwa inkqubo 80-600 mesh amalahle series kaolin;HLMX series calcined kaolin ngokuthe nkqo kakhuluirolailitye lokusila, i-ring roller mill kunye nezinye izixhobo zokutyumza i-ultra-fine zifanelekile ukutyunyuzwa kwe-ultra-fine kwindlela yokuvelisa i-calcined kaolin, ekwazi ukucubungula i-3-45 μ M umgubo we-kaolin ogqwesileyo yi-calcined calcined superfine powder mill.

2. I-calcination kunye ne-whitening process ye-calcined kaolin production method: Ngokujonga iimpawu ze-diagenetic ze-coal series kaolin, oko kukuthi, iqulethe izinto eziphilayo, ukwenzela ukuba ubumhlophe bayo obuluhlaza bube yi-6 ~ 40% kuphela, ekude. ukuhlangabezana neemfuno zomgangatho weshishini lephepha le-kaolin eqatywe, ngoko ke inkqubo yokubala i-decarburization kunye ne-whitening kufuneka yamkelwe.Ngokweemfuno ezahlukeneyo zomgangatho we-kaolin, inokwahlulwa ibe zimveliso ezimbini: ubushushu obuphakathi calcined kaolin kunye nobushushu obuphezulu calcined kaolin.

Inkqubo yokuthelekisa iindlela zokuvelisa i-kaolin calcined: ngokutsho ukuba inkqubo ye-superfine yinkqubo emanzi okanye inkqubo eyomileyo kunye nokulandelelana kwenkqubo ye-superfine kunye nenkqubo yokubala, iinkqubo ezine zemveliso zinokudibaniswa, ezizezi.

(1) inkqubo emanzi ye-superfine elandelwa yinkqubo yokubala (2) inkqubo eyomileyo ye-superfine elandelwa yinkqubo yokubala (3) i-calcination elandelwa yinkqubo ye-superfine emanzi (4) i-calcination elandelwa yinkqubo eyomileyo ye-superfine.Ngenxa yokuba abantu benokuqonda okwahlukileyo kwezixhobo ze-ultra-fine, iindlela zenkqubo ezisetyenziswa kumashishini ahlukeneyo zahlukile:

(1) Inkqubo yokubala emanzi kakhulu inde ngokwentelekiso, kodwa iyakwazi ukuziqhelanisa nemathiriyeli ekrwada, kwaye umgangatho wemveliso unokuhlangabezana neemfuno zoshishino lwephepha;

(2) Ubalo kunye nenkqubo yokumanzisa i-superfine ngokubanzi ifuna izixhobo zokomisa ezikhethekileyo kunye nezixhobo zokusasaza.Le nkqubo inobuthathaka obungaguqukiyo kwizinto eziluhlaza, kodwa inokuvelisa iimveliso ezifunwa lishishini lephepha;

(3) Inkqubo yokubala eyomileyo ephezulu kunye neyokuqala yokubala kunye nenkqubo eyomileyo ye-superfine ayikwazi ukuvelisa i-kaolin kushishino lwephepha (ngenxa yesizathu sezixhobo ezigqwesileyo), efuna umgangatho ophezulu wezinto eziluhlaza.

Lilonke, inkqubo yokomisa i-superfine phambi kokubala kuyasebenza kakhulu, kwaye umzobo wenkqubo wokuhamba uthi: intsimbi ekrwada ekrwada → ukutyumza → ukutyumza → owomileyo ongaphezulu → ubalo → imveliso.Iingenelo zale nkqubo zezi: (1) inkqubo imfutshane, kwaye yonke le nkqubo ifuna kuphela izixhobo ezingundoqo ezintathu ukuya kwezine.Ukuba HongchengI-HLMX calcined kaolin ultrafine powder mill ikhethiwe, izixhobo ezithathu kuphela ezifunekayo, ezizezi, isityumzi, i-calcined kaolin ultrafine powder mill, i-calciner, elungele ulawulo jikelele kunye nokucwangciswa okufanelekileyo;(2) Ukusetyenziswa kwamandla kunengqiqo.Kule nkqubo, inkqubo ye-superfine yezinto ibekwe phambi kwenkqubo yokubala ukuphepha ingxaki yokusebenzisa amandla amaninzi ngenxa yokutyumza kunye nokutshisa izinto.Ukuba inkqubo ye-powder calcination yamkelwe, inokuthathwa njengenkqubo epheleleyo yokuvelisa okomileyo.Ngokubhekiselele kwitekhnoloji, ukusetyenziswa kwamandla kunengqiqo ngakumbi.

Ukusebenzisa uthotho lwamalahle kaolin ukuvelisa ibakala lokugquma i-kaolin calcined kushishino lwephepha ngokungathandabuzekiyo yindlela esebenzayo yokusebenzisa ngokusengqiqweni i-ganggue yamalahle.Kufuneka kuqatshelwe ukuba iindlela zenkqubo ezifanelekileyo kufuneka zikhethwe ngokwezibonelelo zengingqi kunye nenkunzi.Ukuba ufuna ukwazi ngakumbi malunga neendlela zokuvelisa kunye nokukhethwa kwezixhobo ze-calcined kaolin, nceda usitsalele iinkcukacha.
