Kaolin, gaar ahaan ultra-fine calcined kaolin, oo ah walxo aan bir ahayn oo aan organic ahayn oo aad muhiim u ah, ayaa had iyo jeer door muhiim ah ka ciyaartay warshadaha waraaqaha oo leh astaamo jidheed oo aad u wanaagsan.Kaolin-ka calcined ee loo isticmaalo warshadaha warqadaha waa maaddada qaab-dhismeed ee dalool iyo caddaan sare leh, taas oo inta badan loo isticmaalo in lagu beddelo titanium dioxide qaali ah iyo midabyo kale oo heer sare ah.Sida soo saaraha qalabka wax lagu shiido, ahcalcined kaolintoosan ultra-fiicanrullaluistemadkawarshad ay soo saartay HCMilling (Guilin Hongcheng) ayaa si weyn loo isticmaalay oo lagu aqoonsaday soo saarista kaolin-ka calcined.Kuwa soo socdaa waa horudhac ku saabsan habka wax soo saarka ee kaolin-ka calcined:

Shuruudaha tayada ee warshadaha waraaqaha ee kaolin calcined ayaa inta badan lagu muujiyay shuruudaha cabbirka walxaha, cadaanka, awoodda qarinta, nuugista saliidda, feejignaanta viscosity, qiimaha pH, qiimaha xirashada iyo tilmaamayaasha kale ee kaolin calcined.Marka loo eego duruufaha suuqa ee kaolin-ka caadiga ah ee la dhaqo uu sanadba sanadka ka dambeeya hoos u sii dhacayo saamaynta ay leedahay kaalshiyamka karbohaydrayt-ka culus awgeed, iibka suuqa ayaa ahaa mid kor u kacaya, taas oo keentay in warshado badan ay ku daydaan.Tan iyo 1980-meeyadii, tiro badan oo kaolin taxane ah oo dhuxul ah ayaa la helay (waxaa la sheegay in kaydka mustaqbalka uu ka badan yahay 10 bilyan oo tan).Sababtoo ah tayada sare ee ay leedahay iyo wax yar oo wasakh ah oo waxyeello leh, kaolin taxane ah oo dhuxul ah ayaa noqday alaabta ceeriin ee ugu fiican ee soo saarista kaolin-ka daahan warqadda ah.Rajada suuqa ee kaolin-ka calcined ee laga soo saaro kaolin-ka dhuxusha waa mid ballaaran.

Habka wax soo saarka ee kaolin-ka calcined inta badan waxaa ka mid ah laba qaybood: burburinta habka superfine iyo habka nadiifinta calcining.

1. Shiida habka superfine ee habka wax soo saarka kaolin: shiidi habka superfine waa xiriir muhiim ah si loo ogaado tayada kaolin.Burburinta taxanaha dhuxusha 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).calcined kaolinRaymond Mill iyo Calcined kaolin mill toosan oo ay soo saartay HCMilling(Guilin Hongcheng) waa qalab burburin aan dhab ahayn, kaas oo loo isticmaali karo burburinta qalafsan ee hordhaca ah ee habka wax soo saarka kaolin, oo farsamayn kara 80-600 mesh taxane dhuxul kaolin;Taxanaha HLMX calcined kaolin toosan ultra-fiicanrullaluistemadkawarshad, giraanta giraangiraha iyo qalabka kale ee aadka u fiican ee burburinta ayaa ku habboon burburinta ultra-fine ee habka wax soo saarka ee kaolin, kaas oo ka shaqeyn kara 3-45 μM superfine kaolin budada ah ee calcined kaolin superfine.

2. Habka calcined iyo caddaynta habka wax soo saarka kaolin: Marka la eego sifooyinka diagenetic ee taxanaha dhuxusha kaolin, taas oo ah, waxa uu ka kooban yahay qaar ka mid ah maaddada organic, si ay macdanta ceeriin cadcad kaliya 6 ~ 40%, taas oo ka fog. buuxinta shuruudaha tayada waraaqaha ee kaolin-ka dahaarka leh, markaa waa in la qaataa decarburization calcination iyo habka caddeynta.Marka loo eego shuruudaha kala duwan ee tayada kaolin, waxa kale oo loo qaybin karaa laba badeeco: heerkulka dhexdhexaadka ah ee kaolin iyo heerkulka sare ee calcined kaolin.

Habka isbarbardhigga hababka wax soo saarka kaolin ee calcined: iyadoo la raacayo haddii habka superfine uu yahay geeddi-socod qoyan ama geeddi-socod qalalan iyo isku xigxiga habka superfine iyo habka calcination, afar hab-soo-saarka ayaa la isku dari karaa, kuwaas oo kala ah.

(1) habka superfine qoyan oo ay ku xigto habka calcination (2) habka superfine qalalan oo ay ku xigto habka calcination (3) calcination by habka superfine qoyan (4) calcination by habka superfine qalalan.Sababtoo ah dadku waxay leeyihiin faham kala duwan oo ku saabsan alaabta aadka u fiican, dariiqyada habka loo isticmaalo ganacsiyada kala duwan ayaa kala duwan:

(1) Habka calcination superfine qoyan waa mid aad u dheer, laakiin waxa uu leeyahay laqabsiga xooggan ee alaabta ceeriin, iyo tayada alaabta dabooli kartaa baahida warshadaha waraaqaha;

(2) Dib-u-qoynta iyo dib-u-qoynta habka superfine guud ahaan waxay u baahan tahay qalab qalajin gaar ah iyo qalabka kala firdhiso.Habkani wuxuu leeyahay laqabsiga daciifka ah ee alaabta ceeriin, laakiin wuxuu soo saari karaa alaabooyinka looga baahan yahay warshadaha waraaqaha;

(3) Habka calcination superfine qalalan iyo calcination ugu horeysay ka dibna habka superfine qalalan ma soo saari karaan kaolin ee warshadaha waraaqaha (sababtoo ah qalabka superfine), taas oo u baahan tayada sare ee alaabta ceeriin.

Guud ahaan, habka superfine qalalan ka hor calcination waxay leedahay ku dabaqi xoog leh oo xoog leh, iyo jaantus socodka geedi socodka waa: macdanta ceeriin → burburin → burburin → superfine qalalan → calcination → alaabta.Faa'iidooyinka geeddi-socodkani waa: (1) geeddi-socodku waa gaaban yahay, geeddi-socodkuna wuxuu u baahan yahay kaliya saddex ilaa afar qalab oo waaweyn.Haddii HongchengHLMX calcined kaolin ultrafine warshad budada ah waa la doortay, kaliya saddex qalab ayaa loo baahan yahay, kuwaas oo kala ah, burburin, calcined kaolin ultrafine milix, calciner, kaas oo ku habboon maaraynta guud iyo jadwal macquul ah;(2) Isticmaalka tamarta waa macquul.Nidaamkan, habka superfine ee alaabta ayaa la dhigayaa ka hor habka calcination si looga fogaado dhibaatada isticmaalka tamar badan sababtoo ah burburinta iyo walxaha gubanaya.Haddii habka calcination-ka budada ah la qaato, waxaa loo tixgelin karaa habka wax soo saarka qalalan oo buuxa.Ilaa hadda sida tignoolajiyada ay khusayso, isticmaalka tamarta ayaa macquul ah.

Isticmaalka taxanaha dhuxusha kaolin si loo soo saaro kaolin darajada calcined ee warshadaha waraaqaha shaki la'aan waa hab wax ku ool ah oo si macquul ah looga faa'iidaysto gangue dhuxusha.Waa in la ogaadaa in dariiqyada hab-socodka ku habboon lagu doorto iyadoo loo eegayo kheyraadka deegaanka iyo raasumaalka.Haddii aad rabto in aad wax badan ka ogaato hababka wax-soo-saarka iyo xulashada qalabka ee kaolin-ka calcined, fadlan naga soo wac faahfaahinta.
