Guilin Hongkaolin ntsug zeb

Guilin Hongcheng sib tsoo khoom manufacturerskawm tau hais tias calcined kaolin sib tsoo cov khoom yog tsuas yog siv nyob rau hauv lub txheej kev lag luam, uas yog siv los ua ib tug muab tub lim nyob rau hauv cov xim, nyob rau hauv ib tes plays lub luag hauj lwm ntawm lub cev filling, ntawm qhov tod tes muaj ib tug tej yam qhuav npog quab yuam.Yog li, dab tsi yog qhov ntsuas qhov xav tau ntawm calcined kaolin sib tsoo khoom?

Cov khoom lag luam ntsuas ntawm calcined kaolin rau txheej feem ntau suav nrog whiteness, particle loj, npog quab yuam, dispersion, 325 mesh sieve residue, roj nqus tus nqi, deposition ntim, pH nqi, huab cua tsis kam thiab hais txog:

1. Dawb degree

whiteness yog thawj qhov ntsuas ntawm calcined kaolin, qhov siab dua qhov zoo.Cov xim xim kuj yog ua los ntawm cov xim dawb raws li cov xim pleev xim thiab cov xim mother.whiteness yuav tsum tsawg kawg yog ntau dua 90%, qee cov tuam ntxhab txawm xav tau ntau dua 93%.Dawb degree kev ruaj ntseg yog qhov tseem ceeb heev, yog tias qhov kev hloov pauv loj dhau los cuam tshuam rau kev ua haujlwm kho qhov muag ntawm cov txheej txheem, ua rau cov xim sib txawv ntawm cov khoom sib txawv ntawm cov khoom siv tib yam.

2.Granularity

Particle loj yog qhov ua tau qhov ntsuas ntawm tus sawv cev, txheej manufacturers tsis tshua ncaj qha mus xyuas cov particle loj.Txawm li cas los xij, vim tias lwm qhov ntsuas ntawm calcined kaolin ncaj qha ntsig txog qhov loj me, yog tias qhov loj me me tsis zoo txaus, lossis tsis tsim nyog, nws yuav raug cuam tshuam los ntawm lwm cov ntsuas.Rau cov chaw tsim khoom calcined kaolin, qhov ntsuas ntsuas ntawm cov khoom tiav yuav tsum yog-2 μ m ntawm txog 80%.Tau kawg, qhov kev ua tau zoo ntawm cov khoom tsim los ntawm cov khoom siv raw sib txawv yuav txawv, thiab yog tias lwm qhov ntsuas tau tsim nyog, qhov kev xav tau ntawm cov particle loj tuaj yeem raug txo.

Qhov loj me me feem ntau cuam tshuam los ntawm kev hnav ntawm cov ore raw thiab qhov kub ntawm calcination.Lub peev xwm hnav yog txiav txim siab los ntawm qhov zoo ntawm cov ore raw, uas feem ntau cuam tshuam rau qhov loj me ntawm cov khoom siv raw, thiab qhov kub ntawm calcination feem ntau cuam tshuam rau qhov loj me ntawm cov hmoov tom qab lub kiln.Rau txheej calcination kaolin, nruab nrab kub calcination (1000 ~ 1200 ℃), qhov zoo tshaj plaws calcination kub yog xaiv nyob rau hauv lub amorphous theem nyuam qhuav hloov mus rau hauv silicon aluminium spinel theem, uas tsim porous expansion qauv, ua rau lub pore txoj kev loj hlob, thiab tus nqi abrasion. cov khoom yog qhov tsawg.

3. Npog quab yuam

Npog lub zog yog qhov ntsuas tseem ceeb tshaj plaws ntawm calcined kaolin.Qhov zoo dua cov hmoov, ntau qhov sib txuas tsim nyob rau hauv cov txheej txheem, qhov muaj zog dua qhov kev cuam tshuam thiab kev xav ntawm lub teeb, tshwj xeeb tshaj yog thaum cov particle loj sib npaug ntawm lub teeb pom kev zoo, muaj qhov cuam tshuam zoo tshaj plaws, tuaj yeem tsim lub zog loj tshaj plaws, thaum tsawg dua tus nqi no, lub zog npog yuav ua me me vim yog qhov sib txawv ntawm lub teeb.

Rau cov kaolin zoo heev, seb nws puas tuaj yeem tawg tag nrho hauv cov txheej txheem kuj yog ib qho tseem ceeb cuam tshuam rau nws lub hwj chim npog.Txawm hais tias calcination txhim kho lub zog npog ntawm kaolin hauv dej-raws li txheej, nws tsis yog qhov tseem ceeb.Qee zaum, nws yog ib qho yooj yim rau sintering thiab tsim coarse hais, tab sis ua rau lub npog quab yuam txo, thiab nws tsis tuaj yeem siv rau txheej txhua.Lwm qhov teeb meem yog tias calcination hauv qab 1000 ℃ qee zaum ua rau lub teeb liab, uas yog qhov phem heev. rau dawb pigments.1050 ℃ thiab superfine hmoov.

4. Disperssiveness

Kev lag luam txheej hauv tsev hais tias dispersion, thiab lub tswv yim yog tib yam.Txawm hais tias calcined kaolin tau dhau los ua cov hmoov ultrafine, nrog qhov nruab nrab ntawm qhov loj me ntawm 1 μ m lossis tsawg dua, hauv cov xim, hauv cov kua txiv hmab txiv ntoo siab, cov khoom tsis sib cais tab sis ua ke ua ke.Lub peev xwm ntawm calcined kaolin disperse nyob rau hauv lub txheej txheej yog hu ua dispersion.Lub dispersion ntawm calcined kaolin yog zoo.Yog tias qib sib tsoo ua tau raws li qhov xav tau kawg, nws tuaj yeem tawg mus rau hauv cov txheej txheem txheej txheej.

Lub dispersion ntawm calcined kaolin muaj feem xyuam rau qhov kawg ntawm kev sib tsoo.Yog hais tias 45 μ m los yog cov khoom loj dua muaj nyob rau hauv cov txheej txheem superfine, nws yuav tsis tawg mus rau hauv txheej txheej txheej.Qhov kev xav tau rau qhov ntsuas no tsawg dua 45 μ m, thiab qhov me me, qhov zoo dua.Yog tias qhov tawg ntawm titanium dioxide tuaj yeem ncav cuag 25 μ m, sib haum rau qib sib tsoo yuav tsum xaiv 4 lossis ntau dua.

5.325 mesh sieve residue

325 mesh sieve residue yog ib qho tseem ceeb Performance index, qhov yuav tsum tau ntawm txheej rau qhov ntsuas no yog <0.02%, thiab qhov me dua qhov zoo dua.325 mesh sieve kuj tseem muaj feem xyuam rau qhov kawg tshwm sim ntawm kev sib tsoo, yuav tsum tsis muaj 45 μ m los yog loj hais thaum lub sij hawm. kev ua ultrafine.Lwm qhov cuam tshuam yog impurities, tov nrog impurities muaj qhov pom tseeb tshaj plaws ntawm kev tshuaj xyuas cov ntsiab lus ntawm 325 mesh.

6.Oil absorption nqi

Cov roj nqus cov nqi ntawm calcined kaolin yog 50g / 100g ~ 60g / 100g yog nruab nrab, cov roj nqus dej ntau dhau, cov txheej viscosity ua nrog tib cov mis loj, txhawm rau txo cov viscosity, cov xim ntawm cov xim yuav tsum tau. nce tus nqi;cov roj nqus cov nqi qis dhau lawm, cov txheej txheej ua tau yooj yim los daws, thiab qhov qhib kev ua haujlwm tsis zoo.Cov roj nqus tus nqi ntawm kaolin yog particle loj tis, porosity, tshwj xeeb thaj chaw, thiab grain hom hais.Cov particle loj me me, qhov tshwj xeeb ntawm qhov chaw yog loj dua, thiab cov nqi nqus roj yog

7.Kev ntim ntim

Cov roj nqus cov nqi ntawm calcined kaolin yog 50g / 100g ~ 60g / 100g yog nruab nrab, cov roj nqus dej ntau dhau, cov txheej viscosity ua nrog tib cov mis loj, txhawm rau txo cov viscosity, cov xim ntawm cov xim yuav tsum tau. nce tus nqi;cov roj nqus cov nqi qis dhau lawm, cov txheej txheej ua tau yooj yim los daws, thiab qhov qhib kev ua haujlwm tsis zoo.Cov roj nqus tus nqi ntawm kaolin yog particle loj tis, porosity, tshwj xeeb thaj chaw, thiab grain hom hais.Cov particle loj me me, qhov tshwj xeeb ntawm qhov chaw yog loj dua, thiab cov roj nqus cov nqi siab dua.

8. pH tus nqi

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

9. Huab cua tsis kam

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

10.Lwm yam ntsuas

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
