Guilin Hongkaolin ntsug zeb

Guilin Hongcheng cov khoom siv sib tsoo cov chaw tsim khoomkawm tau tias cov khoom sib tsoo calcined kaolin feem ntau yog siv rau hauv kev lag luam txheej, uas yog siv los ua cov khoom sau rau hauv cov xim, ntawm ib sab tes ua lub luag haujlwm ntawm kev sau lub cev, ntawm qhov tod tes muaj qee lub zog npog qhuav. Yog li, cov ntsuas qhov yuav tsum tau ua ntawm cov khoom sib tsoo calcined kaolin yog dab tsi?

Cov khoom lag luam ntawm calcined kaolin rau txheej feem ntau suav nrog qhov dawb, qhov loj me ntawm cov khoom me me, lub zog npog, kev tawg, 325 mesh sieve residue, tus nqi nqus roj, ntim tso tawm, tus nqi pH, tiv taus huab cua thiab lwm yam:

1. Qib dawb

Qhov dawb yog qhov ntsuas tseem ceeb ntawm cov kaolin calcined, qhov siab dua qhov zoo dua. Cov xim pleev xim kuj tseem ua nrog cov xim dawb ua cov xim pleev xim thiab xim niam. Qhov dawb yuav tsum tsawg kawg yog ntau dua 90%, qee cov chaw tsim khoom txawm tias xav tau ntau dua 93%. Qhov ruaj khov ntawm qhov dawb yog qhov tseem ceeb heev, yog tias qhov kev hloov pauv loj dhau los cuam tshuam rau kev ua haujlwm ntawm lub txheej, ua rau muaj qhov sib txawv ntawm cov xim ntawm cov khoom sib txawv hauv qab tib yam mis.

2. Kev ua kom me me

Qhov loj ntawm cov khoom me me yog qhov tseeb ntawm kev sawv cev, cov tuam txhab tsim khoom txheej tsis tshua ncaj qha los ntes qhov loj ntawm cov khoom me me. Txawm li cas los xij, vim tias lwm cov cim qhia ntawm calcined kaolin muaj feem cuam tshuam ncaj qha rau qhov loj ntawm cov khoom me me, yog tias qhov loj ntawm cov khoom me me tsis zoo txaus, lossis tsis tsim nyog, nws yuav raug cuam tshuam los ntawm lwm cov cim qhia. Rau cov chaw tsim khoom calcined kaolin, qhov ntsuas kev tshuaj xyuas ntawm cov khoom tiav yuav tsum yog -2 μ m ntawm kwv yees li 80%. Tau kawg, kev ua tau zoo ntawm cov khoom tsim los ntawm cov khoom siv raw sib txawv yuav txawv, thiab yog tias lwm cov cim qhia tau tsim nyog, qhov yuav tsum tau ua ntawm cov khoom me me kuj tseem tuaj yeem txo qis.

Qhov loj ntawm cov khoom me me feem ntau cuam tshuam los ntawm kev hnav ntawm cov hlau nyoos thiab qhov kub ntawm calcination. Lub peev xwm hnav yog txiav txim siab los ntawm qhov zoo ntawm cov hlau nyoos, uas feem ntau cuam tshuam rau qhov loj ntawm cov khoom siv raw, thiab qhov kub calcination feem ntau cuam tshuam rau qhov loj ntawm cov hmoov tom qab lub qhov cub. Rau kev txheej calcination kaolin, calcination kub nruab nrab (1000 ~ 1200 ℃), qhov kub calcination zoo tshaj plaws yog xaiv hauv theem amorphous tsuas yog hloov mus rau theem silicon txhuas spinel, uas tsim cov qauv nthuav dav, ua rau muaj kev loj hlob ntawm cov hlau, thiab tus nqi abrasion ntawm cov khoom yog qis dua.

3. Lub zog npog

Lub zog npog yog qhov tseem ceeb tshaj plaws ntawm cov kaolin calcined. Cov hmoov zoo dua, qhov sib txuas ntau dua hauv cov txheej, qhov muaj zog dua qhov kev cuam tshuam thiab kev cuam tshuam ntawm lub teeb, tshwj xeeb tshaj yog thaum qhov loj me ntawm cov khoom me me sib npaug rau qhov ntev ntawm lub teeb pom kev, muaj qhov cuam tshuam tawg muaj zog tshaj plaws, tuaj yeem tsim lub zog npog loj tshaj plaws, thaum tsawg dua tus nqi no, lub zog npog yuav me dua vim yog qhov sib txawv ntawm lub teeb.

Rau cov kaolin uas me dhau, seb nws puas tuaj yeem tawg tag nrho hauv cov txheej kuj yog ib qho tseem ceeb uas cuam tshuam rau nws lub zog npog. Txawm hais tias calcination txhim kho lub zog npog ntawm kaolin hauv cov txheej dej, nws tsis tseem ceeb. Qee zaum, nws yooj yim rau sintering thiab tsim cov khoom me me, tab sis ua rau lub zog npog txo qis, thiab nws tsis tuaj yeem siv rau kev txheej txhua. Lwm qhov teeb meem yog tias calcination hauv qab 1000 ℃ qee zaum tsim cov theem liab, uas yog qhov phem heev rau cov xim dawb. 1050 ℃ thiab superfine hmoov.

4. Kev tawg tawm

Kev lag luam txheej hauv tsev hais tias kev sib kis, thiab lub tswv yim zoo ib yam. Txawm hais tias cov kaolin calcined tau dhau los ua hmoov zoo heev, nrog rau qhov nruab nrab ntawm 1 μ m lossis tsawg dua, hauv cov xim, hauv cov kua txiv hmab txiv ntoo siab viscosity, cov khoom me me tsis sib cais tab sis sib sau ua ke. Lub peev xwm ntawm calcined kaolin kom tawg hauv lub kaw lus txheej yog hu ua kev sib kis. Kev sib kis ntawm calcined kaolin yog qhov zoo. Yog tias qib sib tsoo ua tau raws li qhov yuav tsum tau ua kawg, nws tuaj yeem tawg hauv lub kaw lus txheej.

Qhov kev tawg ntawm cov kaolin calcined muaj feem cuam tshuam rau qhov kawg ntawm kev sib tsoo. Yog tias muaj 45 μ m lossis cov khoom loj dua nyob hauv cov txheej txheem ua tiav superfine, nws yuav tsis tawg hauv lub kaw lus txheej. Qhov yuav tsum tau ua rau cov ntsuas no tsawg dua 45 μ m, thiab qhov me dua, qhov zoo dua. Yog tias qhov kev tawg ntawm titanium dioxide tuaj yeem ncav cuag 25 μ m, sib xws rau qib sib tsoo yuav tsum tau xaiv ua 4 lossis ntau dua.

5.325 mesh sieve residue

325 mesh sieve residue yog ib qho tseem ceeb index, qhov yuav tsum tau ntawm txheej rau qhov index no yog <0.02%, thiab qhov me dua qhov zoo dua.325 mesh sieve kuj tseem ceeb rau qhov kawg ntawm kev sib tsoo, tsis tas yuav tsum muaj 45 μ m lossis cov khoom loj dua thaum lub sijhawm ua ultrafine. Lwm qhov cuam tshuam yog impurities, sib xyaw nrog impurities muaj qhov cuam tshuam pom tseeb tshaj plaws rau cov ntsiab lus tshuaj ntsuam ntawm 325 mesh.

6. Tus nqi nqus roj

Tus nqi nqus roj ntawm calcined kaolin yog 50g / 100g ~ 60g / 100g yog qhov nruab nrab, qhov ntau ntawm cov roj nqus yog siab dhau, qhov viscosity ntawm cov txheej ua nrog tib lub mis yog loj, txhawm rau kom txo qhov viscosity, qhov ntau ntawm cov xim pleev xim yuav tsum nce tus nqi; tus nqi nqus roj tsawg dhau, cov txheej ua yooj yim rau kev daws, thiab qhov kev ua tau zoo qhib tsis zoo. Tus nqi nqus roj ntawm kaolin yog qhov faib tawm ntawm cov khoom me me, porosity, thaj chaw tshwj xeeb, thiab hom noob ntawm cov khoom me me. Qhov loj me ntawm cov khoom me me, thaj chaw tshwj xeeb loj dua, thiab tus nqi nqus roj yog

7. Kev them nqi

Tus nqi nqus roj ntawm calcined kaolin yog 50g / 100g ~ 60g / 100g yog qhov nruab nrab, qhov nqus roj ntau dhau, qhov viscosity ntawm txheej ua nrog tib lub mis yog loj, txhawm rau txo qhov viscosity, qhov ntau ntawm cov xim pleev xim yuav tsum nce tus nqi; tus nqi nqus roj tsawg dhau, cov txheej ua yooj yim rau kev daws, thiab qhov kev ua tau zoo qhib tsis zoo. Tus nqi nqus roj ntawm kaolin yog qhov faib tawm ntawm cov khoom me me, porosity, thaj chaw tshwj xeeb, thiab hom noob ntawm cov khoom me me. Qhov loj me me yog me, thaj chaw tshwj xeeb loj dua, thiab tus nqi nqus roj siab dua.

8. tus nqi pH

Tus nqi pH qhia txog cov kua qaub thiab alkalinity ntawm calcined kaolin, thiab tus nqi pH yuav tsum nyob nruab nrab ntawm 6 thiab 8, feem ntau ze rau qhov nruab nrab. PH ntawm calcined kaolin nws tus kheej yog qhov nruab nrab, yog li qhov kev hloov kho PH tsis tas yuav tsum muaj hauv kev lag luam txheej.

9. Huab cua tsis kam

Tom qab cov xim ua los ntawm xim thiab pleev xim, cov xim zaj duab xis los ntawm lub hnub thiab nag, yuav tig daj, poob lub teeb thiab hmoov. Lub peev xwm ntawm cov xim los tiv thaiv cov kev hloov pauv no hu ua kev tiv thaiv huab cua. Calcined kaolin tsis muaj zog tshuaj lom neeg ua haujlwm ntawm lub teeb, yog li nws muaj kev tiv thaiv huab cua zoo.

10. Lwm yam cim qhia

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
