Kaolin, gaar ahaan kaolin-ka calcined-ka ah ee aadka u fiican, oo ah walxo aan dabiici ahayn oo aan dabiici ahayn, ayaa had iyo jeer door muhiim ah ka ciyaartay warshadaha warqadda iyadoo leh sifooyinkeeda jireed ee aadka u fiican. Kaolin-ka calcined ee loo isticmaalo warshadaha warqadda waa walxo qaab-dhismeed oo cad oo daloolsan oo heer sare ah, kaas oo inta badan loo isticmaalo in lagu beddelo titanium dioxide qaali ah iyo midabyo kale oo heer sare ah. Iyada oo ah soo saaraha qalabka shiididda,kaolin oo lagu daray kaalshiyamToosan oo aad u fiicanroogagawarshad Waxaa soo saaray HCMill (Guilin Hongcheng) si weyn ayaa loogu isticmaalay loona aqoonsaday soo saarista kaolin calcined. Kuwa soo socdaa waa hordhac ku saabsan habka wax soo saarka kaolin calcined:

Shuruudaha tayada ee warshadaha warqadda ee kaolin-ka kaalshiyamka waxaa inta badan lagu muujiyay shuruudaha cabbirka walxaha, caddaanka, awoodda qarsoon, nuugista saliidda, fiirsashada viscosity, qiimaha pH, qiimaha xirashada iyo tilmaamayaasha kale ee kaolin-ka kaalshiyamka. Xaaladaha suuqa kaolin-ka ee caadiga ah ee la dhaqay uu sii yaraanayay sannadba sannadka ka dambeeya sababtoo ah saameynta kaalshiyamka kaalshiyamka culus, iibka suuqu wuu korayay, taas oo ka dhigtay soo-saareyaal badan inay raacaan. Tan iyo 1980-meeyadii, tiro badan oo kaolin-ka taxanaha dhuxusha ah ayaa la helay (waxaa la sheegay in kaydka mustaqbalka uu ka badan yahay 10 bilyan oo tan). Sababtoo ah tayo sare iyo waxyaabo yar oo wasakh ah oo waxyeello leh, kaolin-ka taxanaha dhuxusha ayaa noqday agab ceeriin ah oo ku habboon soo saarista kaolin-ka kaalshiyamka ee heerka dahaarka warqadda. Rajada suuqa ee kaolin-ka kaalshiyamka ee laga soo saaro taxanaha dhuxusha kaolin waa mid ballaaran.

Habka wax soo saarka ee kaolin-ka la qalajiyey wuxuu inta badan ka kooban yahay laba qaybood: burburinta habka superfine iyo habka cadaynta calcining.

1. Habka shiididda superfine ee habka wax soo saarka kaolin ee kalsiyum: shiididda superfine habka waa isku xir muhiim ah si loo go'aamiyo tayada kaolin. Burburinta taxanaha dhuxusha ee kaolin superfine waa kaolin adag (laga bilaabo 5 ~ 20mm ilaa 40 ~ 80 μm) Ultrafine (laga bilaabo 40 ilaa 80 μM ilaa – 10 μM ama – 2 μm).kaolin oo lagu daray kaalshiyamMashiinka Raymond iyo mashiinka duubista toosan ee kaolin ee calcined oo ay soo saarto HCMill (Guilin Hongcheng) waa qalab burburin ah oo qallafsan, kaas oo loo isticmaali karo burburinta hore ee habka wax soo saarka kaolin ee calcined, waxayna farsamayn kartaa 80-600 oo kaolin taxane dhuxul ah oo mesh ah;Taxanaha HLMX ee kaolin oo la kariyey Toosan oo aad u fiicanroogagawarshad, mashiinka duubista giraanta iyo qalabka kale ee burburinta aadka u fiican ayaa ku habboon burburinta aadka u fiican habka wax soo saarka ee kaolin calcined, kaas oo farsamayn kara budada kaolin superfine 3-45 μM waa warshad budada kaolin superfine calcined oo ku habboon.

2. Habka kalifinta iyo cadaynta habka wax soo saarka kaolin ee kalsiyum: Marka la eego astaamaha diagnosis-ka ee kaolin taxanaha dhuxusha, taasi waa, waxa ku jira walxo dabiici ah, si cadaanteeda macdanta cayriin ay u tahay 6 ~ 40% oo keliya, taas oo ka fog buuxinta shuruudaha tayada ee warshadaha warqadda ee kaolin dahaarka leh, sidaa darteed waa in la qaataa habka kalifinta iyo cadaynta. Sida laga soo xigtay shuruudaha kala duwan ee tayada kaolin, waxa kale oo loo qaybin karaa laba badeecood: kaolin heerkul dhexdhexaad ah oo kalsiyum ah iyo kaolin heerkul sare leh oo kalsiyum ah.

Isbarbardhigga habka ee hababka wax soo saarka kaolin ee kalsiyum-ka lagu sameeyay: iyadoo la eegayo in habka superfine uu yahay habka qoyan ama habka qalalan iyo taxanaha habka superfine iyo habka calcination, afar hab oo wax soo saar ayaa la isku dari karaa, kuwaas oo kala ah

(1) habka qoyan ee superfine oo ay ku xigto habka kalsiyumaynta (2) habka qalalan ee superfine oo ay ku xigto habka kalsiyaynta (3) kalsiyaynta oo ay ku xigto habka qoyan ee superfine (4) kalsiyaynta oo ay ku xigto habka qalalan ee superfine. Maadaama dadku ay si kala duwan u fahmaan agabka aadka u fiican, waddooyinka habka loo isticmaalo shirkadaha kala duwan way kala duwan yihiin:

(1) Habka kalsiyumka qoyan ee superfine waa mid dheer, laakiin wuxuu leeyahay la qabsi xooggan oo ku habboon walxaha ceeriin ah, tayada badeecaduna waxay dabooli kartaa baahiyaha warshadaha warqadda;

(2) Habka kalsiyaynta iyo dib-u-qoynta superfine guud ahaan wuxuu u baahan yahay qalab qalajin gaar ah iyo qalab kala firdhisan. Habkani wuxuu leeyahay la qabsi daciif ah oo ku habboon walxaha ceeriin ah, laakiin wuxuu soo saari karaa badeecooyin ay u baahan yihiin warshadaha warqadda;

(3) Habka kalsiyeynta qalalan ee superfine iyo habka kalsiyeynta koowaad ka dibna habka superfine ee qalalan ma soo saari karo kaolin warshadaha warqadda (sababtoo ah qalabka superfine), kaas oo u baahan tayo sare oo agab ceeriin ah.

Guud ahaan, habka loo isticmaalo superfine qalalan ka hor ka saarista wuxuu leeyahay ku-dhaqan wax ku ool ah oo xooggan, jaantuska socodka habkana waa: macdan cayriin ah → burburin → burburin → superfine qalalan → kalluumeysi → badeecad. Faa'iidooyinka habkan waa: (1) geeddi-socodku waa gaaban yahay, geeddi-socodka oo dhanna wuxuu u baahan yahay saddex ilaa afar qalab oo waaweyn oo keliya. Haddii HongchengHLMX kaolin oo ah budada budada ah ee ultrafine marka la doorto, saddex qalab oo keliya ayaa loo baahan yahay, kuwaas oo kala ah, jajabiye, warshad budada kaolin ultrafine ah oo calcined ah, calciner, kaas oo ku habboon maaraynta guud iyo jadwalka macquulka ah; (2) Isticmaalka tamarta waa macquul. Habkan, habka superfine ee agabka ayaa la hor dhigaa habka calcination si looga fogaado dhibaatada ah in la isticmaalo tamar badan oo ay ugu wacan tahay burburinta iyo gubashada agabka. Haddii habka calcination ee budada la qaato, waxaa loo arki karaa hab wax soo saar oo qalalan oo dhammaystiran. Inta ay tiknoolajiyaddu khusayso, isticmaalka tamarta ayaa aad u macquulsan.

Isticmaalka kaolin taxanaha dhuxusha si loo soo saaro kaolin calcined oo heer sare ah warshadaha warqadda shaki la'aan waa hab wax ku ool ah oo si macquul ah loogu isticmaalo gangue dhuxusha. Waa in la ogaadaa in waddooyinka habka ku habboon loo doorto iyadoo loo eegayo kheyraadka maxalliga ah iyo raasamaalka.
