Waa maxay shuruudaha tusaha ee kaolin-ka calcined ee loo isticmaalo soo saarista alaabta daahan?

Guilin Hongkaolin warshad toosan

Guilin Hongcheng qalabka wax lagu shiidoWaxay ogaatay in alaabta wax lagu shiido kaolin ee inta badan loo isticmaalo warshadaha daahan, taas oo loo isticmaalo buuxinta rinjiga, dhinaca kale waxay ka ciyaaraan doorka buuxinta jirka, dhinaca kale waxay leedahay xoog daboolan oo qalalan.Haddaba, waa maxay shuruudaha tusaha ee alaabta wax lagu shiido kaolin ee calcined?

Tusmooyinka wax soo saarka ee kaolin calcined ee daahan inta badan waxaa ka mid ah caddaanka, cabbirka walxaha, xoogga daboolka, kala firdhinta, 325 mesh hadhaaga shaandhada, qiimaha nuugista saliidda, mugga kaydinta, qiimaha pH, caabbinta cimilada iyo wixii la mid ah:

1.Dheraad cad

Cadaannimadu waa tusaha aasaasiga ah ee kaolin-ka calcined, marba marka ka dambaysa way ka fiican tahay.Rinjiga midabka ayaa sidoo kale lagu sameeyay rinji cad sida rinjiga salka iyo midabka hooyada.caddaannimadu waa inay ahaataa ugu yaraan ka badan 90%, qaar ka mid ah wax soo saarka ayaa xitaa u baahan in ka badan 93%.Dejinta heerka cad waa mid aad muhiim u ah, haddii isbeddelku uu aad u weyn yahay si uu u saameeyo waxqabadka indhaha ee daahan, taasoo keentay kala duwanaanshaha midabka ee qaybaha kala duwan ee alaabooyinka hoos yimaada isla caanaha.

2.Granularity

Cabbirka qayb ka mid ah dhab ahaantii waa index of matalaad, saarayaasha daahan dhif ah si toos ah si ay u ogaadaan size qayb ka.Si kastaba ha ahaatee, sababtoo ah tilmaamayaasha kale ee kaolin calcined waxay si toos ah ula xiriiraan xajmiga walxaha, haddii cabbirka qaybku aanu ku filnayn, ama aan u qalmin, waxay ka muuqan doontaa tilmaamayaasha kale.Soo saaraha kaolin-ka la kariyey, tusmada kormeerka ee alaabta la dhammeeyey waa inay noqotaa -2 μm qiyaastii 80%.Dabcan, waxqabadka alaabooyinka ay soo saaraan alaabta ceeriin ee kala duwan way ka duwanaan doontaa, iyo haddii tilmaamayaasha kale ay u qalmaan, shuruudaha xajmiga qaybta ayaa sidoo kale la dhimi karaa.

Cabbirka walxaha waxaa inta badan saameeya xirashada macdanta ceeriin iyo heerkulka calcination.Awoodda xirashada waxaa lagu go'aamiyaa tayada macdanta ceyriinka ah, taas oo inta badan saameysa cabbirka qayb ka mid ah marxaladda alaabta ceeriin, iyo heerkulka calcination inta badan wuxuu saameeyaa xajmiga walxaha budada ah ka dib foornada.Dahaarka calcination kaolin, caleenta heerkulka dhexdhexaadka ah (1000 ~ 1200 ℃), heerkulka ugu fiican ee calcination waxaa lagu doortay in wajiga amorphous kaliya bedelay silicon aluminium spinel wajiga, kaas oo soo saara qaab-dhismeedka fidinta dalool, taasoo keentay horumarinta dalool, iyo qiimaha abrasion ee badeecadu waa mid aad u hooseysa.

3.Xoog daboosho

Daboolida awoodda ayaa ah tusaha ugu muhiimsan ee kaolin-ka calcined.The finer budada ah, interface ka badan ka samaysan ee daahan, ka xoog refraction iyo milicsiga iftiinka, gaar ahaan marka size qayb ka mid ah la siman yahay hirarka iftiinka muuqda, waxa uu leeyahay saamaynta kala firdhiso ugu xooggan, soo saari kartaa xoogga ugu weyn ee daboosho. marka uu ka yar yahay qiimahan, xoogga daboolku wuu yaraan doonaa sababtoo ah kala duwanaanshaha iftiinka.

Kaolin aad u fiican, haddii ay si buuxda ugu kala firdhi karto dahaarka sidoo kale waa arrin muhiim ah oo saameynaysa awoodda daboolida.Inkasta oo calcination-ku uu hagaajiyo awoodda daboolida kaolin ee daahan biyaha ku salaysan, ma aha mid muhiim ah.Xaaladaha qaarkood, way fududahay in la sintering oo ay sameeyaan qaybo qallafsan, laakiin waxay hoos u dhigtaa xoogga daboolka, oo looma isticmaali karo daahan oo dhan. Dhibaatada kale waa in calcination ka hooseeya 1000 ℃ mararka qaarkood waxay soo saartaa weji casaan khafiif ah, taas oo aad u xun. midabada cadcad.1050℃ iyo budada superfine.

4.Khaafsanaan

Warshadaha daahan gudaha ayaa sheegay in kala firidhsan, iyo fikradda waa isku mid.Inkasta oo kaolin-ka calcined lagu sameeyay budo ultrafine ah, oo leh celceliska cabbirka walxaha 1 μm ama ka yar, rinjiga, ku jira khamriga maangagga sarreeya ee waalidka, qaybuhu ma kala soocaan laakiin waa la isku daray.Awooda kaolin calcined in ay ku firdhiso nidaamka daahan waxa loo yaqaan kala firdhiso.Kala firdhinta kaolin-ka calcined ayaa fiican.Haddii darajada wax shiididu ay buuxiso shuruudaha kama dambaysta ah, waxaa lagu kala firdhi karaa nidaamka daahan.

Kala firdhinta kaolin-ka calcined waxay la xiriirtaa saameynta ugu dambeysa ee shiididda.Haddii 45 μm ama qaybo ka weyn ay ku jiraan habka habaynta superfine, laguma kala firdhi doono nidaamka daahan.Shuruudaha tusmadani waa in ka yar 45 μm, iyo inta yar, ayaa ka fiican.Haddii kala firidhsan ee titanium dioxide gaari karo 25 μm, u dhiganta darajada shiidi waa in loo doortaa sida 4 ama ka badan.

5.325 haraaga shaandho mesh

325 haraaga shaandhada mesh waa index muhiim ah, shuruudaha daahan ee tusahan waa <0.02%, iyo inta yar ee ka sii fiican. farsamaynta ultrafine.Arrin kale oo saameyn leh ayaa ah wasakhda, oo lagu qaso wasakhda ayaa saameynta muuqata ku leh nuxurka baarista ee 325 mesh.

6.Qiimaha nuugista saliidda

Qiimaha nuugista saliidda ee kaolin calcined waa 50g / 100g ~ 60g / 100g waa dhexdhexaad, qadarka nuugista saliidda waa mid aad u sarreeya, viscosity daahan oo lagu sameeyay isla formula waa weyn yahay, si loo yareeyo viscosity, qadarka saldhigga rinjiga waa in. kordhinta kharashka;Qiimaha nuugista saliidda ayaa aad u hooseeya, daboolka la sameeyay waa sahlan tahay in la dejiyo, waxqabadka furitaanka ma fiicna.Qiimaha nuugista saliidda ee kaolin waa qaybinta cabbirka walxaha, porosity, bedka dusha gaarka ah, iyo nooca hadhuudhka ee qaybaha.Xajmiga qaybku waa yar yahay, aagga gaarka ah waa ka weyn yahay, iyo qiimaha nuugista saliidda waa

7.Mugga dejinta

Qiimaha nuugista saliidda ee kaolin calcined waa 50g / 100g ~ 60g / 100g waa dhexdhexaad, qadarka nuugista saliidda waa mid aad u sarreeya, viscosity daahan oo lagu sameeyay isla formula waa weyn yahay, si loo yareeyo viscosity, qadarka saldhigga rinjiga waa in. kordhinta kharashka;Qiimaha nuugista saliidda ayaa aad u hooseeya, daboolka la sameeyay waa sahlan tahay in la dejiyo, waxqabadka furitaanka ma fiicna.Qiimaha nuugista saliidda ee kaolin waa qaybinta cabbirka walxaha, porosity, bedka dusha gaarka ah, iyo nooca hadhuudhka ee qaybaha.Xajmiga qaybku waa yar yahay, aagga gaarka ah waa ka weyn yahay, iyo qiimaha nuugista saliidda ayaa ka sarreeya.

8.qiimaha pH

Qiimaha pH wuxuu ka tarjumayaa aashitada iyo alkalinity ee kaolin-ka calcined, iyo qiimaha pH waa inuu u dhexeeyaa 6 iyo 8, asal ahaan u dhow dhexdhexaad.PH ee kaolin-ka calcined lafteedu waa dhexdhexaad, markaa wax ka beddelka PH loogama baahna warshadaha daahan.

9.Cabsiga cimilada

Ka dib markii midabku ka sameysan yahay rinji iyo dhoobo, filimka rinjiga ee qorraxda iyo roobka, wuxuu isu rogi doonaa jaalle, lumin doona iftiin iyo budo.Awoodda midabada si ay uga hortagaan isbeddeladan waxaa loo yaqaan caabbinta cimilada.Kaolin-ka Calcined ma laha dhaqdhaqaaq kiimiko oo xoog leh iftiinka, sidaas darteed waxay leedahay iska caabin cimilo oo wanaagsan.

10. Tilmaamayaal kale

ther index requirements for calcined kaolin, acid and alkali resistance, mixing performance, wet performance, density, etc., these are the common characteristics of all calcined kaolin, some are not digital indicators. It is worth paying attention to that, no matter which index of kaolin, the stability of the index is the most important, if the fluctuation is too big, it will bring bad influence to the paint users, affect the overall performance of the paint. As the production equipment of calcined kaolin mill products, it has an important influence on the whiteness, particle size and 325 mesh residue of calcinined kaolin mill products. Guilin Hongcheng grinding equipment can be ground kaolin to 80-2500 mesh for the production of coating, grinding equipment with high output, low energy consumption, consulting equipment price can contact the email:mkt@hcmilling.com
