Calcined kaolin

Calcined kaolin originated nyob rau hauv lub tebchaws United States, pib los tshem tawm cov organic carbon nqi nyob rau hauv mos kaolin thiab txhim kho cov whiteness ntawm cov khoom.Tom qab ntawd, tib neeg siv txoj kev no los ua cov txheej txheem thee- ntsuas kaolin, thiab tsim cov khoom lag luam nrog kev ua tau zoo, qib siab, thiab tus nqi siab dua li cov kaolin zoo tib yam.Ua kom dav dav ntawm daim ntawv thov ntawm kaolin.Kuv lub teb chaws muaj ntau cov thee- ntsuas kaolin cov peev txheej, thiab calcination yog txheej txheem tseem ceeb rau cov thee ntsuas av siab.

Lub hom phiaj tseem ceeb ntawm kaolin calcination yog:
1. Tshem tawm cov organic carbon thiab lwm yam impurity minerals los txhim kho whiteness.
2. Tshem tawm cov dej thiab hydroxyl pawg ntawm Kaolin kom ua kom lub ntim tsis muaj zog thiab tshuaj lom neeg reactivity ntawm cov khoom calcined, txhim kho lub cev thiab tshuaj lom neeg, thiab ua tau raws li ntau yam kev thov.Cov calcined kaolin raug tshem tawm los ntawm cov qauv lossis cov dej siv lead ua, cov pa roj carbon thiab lwm yam khoom tsis haum, thiab dhau los ua kaolinite, lub npe lag luam yog "calcined kaolin".
Xam kaolin muaj qhov zoo ntawm kev ceev nrawm, thaj av me me, cov roj tsis kam, thiab ras rwb thaiv tsev thiab muaj zog.

Nta:
1. Cov tshuaj muaj pes tsawg leeg yog ruaj khov, qhov molar piv ntawm Si02 / Al203 yog 2/1.
2. Lub whiteness yog ntshiab thiab ruaj khov, particle loj yog ultra-nplua, thiab qhov dav faib thiab lub sieve residue yog tsawg.
3. Lub flaky crystal zoo yog tiav, dispersion yog zoo, lub npog lub hwj chim yog muaj zog, thiab lub floatability yog zoo, thiab nws tsis yooj yim rau precipitate.

Kev siv Calcined Kaolin
1. Calcined kaolin rau txheej
Scope ntawm daim ntawv thov: Ntau hom txheej, nrog rau cov xim latex, hmoov txheej, roj-raws li txheej thiab lwm yam.
Khoom nta: siab dawb, nplua particle loj, tshuaj inertness, siab npog muaj peev xwm, zoo tagnrho fluidity thiab floatability, tsis muaj nqi, thiab lwm yam., uas yuav txo tau cov nqi kim dyes;Ntxiv nrog rau cov yam ntxwv saum toj no, nws kuj muaj qhov zoo ntawm cov duab tsis zoo, cov khoom siv kho qhov muag zoo, cov roj siab nqus thiab cov xim ntim cov ntsiab lus, tsis yooj yim rau hnub nyoog, hnav-tiv taus thiab yooj yim rau emulsify hauv dej lossis roj nruab nrab, thiab muaj lub zog zais siab.Qhov tseem ceeb tshaj plaws yog nws tuaj yeem hloov cov khoom kim heev titanium dioxide, thiab tuaj yeem txo qhov tshwm sim ntawm photocoagulation tshwm sim los ntawm kev siv titanium dioxide thaum sib xyaw thiab siv;tshwj xeeb tshaj yog rau kev tsim cov latex-zoo li pigments, nws tuaj yeem ua rau cov txheej txheem zoo dua opacity thiab corrosion kuj.Txhim kho qhov hardness thiab zoo ntawm cov zaj duab xis txheej.

2. Calcined kaolin rau roj hmab
Scope ntawm daim ntawv thov: txhua yam ntawm cov khoom siv roj hmab thiab cov khoom yas thiab cable sheath, cable rwb thaiv tsev txheej thiab PVC, PE thiab lwm yam ntaub ntawv cable.
Khoom nta: tsim nyog particle loj tis, ntshiab kev ntxhib los mos, tsis muaj impurity cov ntsiab lus, kaolin kaum ntsiab lus ntau dua 98%, zoo dispersibility, nplua particle loj, zoo affinity nrog roj hmab thiab yas, zoo heev txhim kho nyob rau hauv cov roj hmab thiab yas.Nws muaj cov tshuaj zoo inertness thiab tsis hnov ​​​​mob nrog tshuaj lossis lwm yam tshuaj reagents ntawm chav tsev kub, yog li txhim kho corrosion kuj ntawm cable khoom;siab refractoriness tuaj yeem txhim kho cov thermal denaturation kub ntawm cov khoom siv cable;Cov khoom siv hluav taws xob zoo heev, thiab lwm yam.

3. Calcined kaolin rau ceramics
Scope ntawm daim ntawv thov: siab thiab tsis tshua muaj hluav taws xob hluav taws xob ceramics, niaj hnub siv ceramics, tsev huv si ceramics, tshuaj corrosion-resistant ceramics thiab glazes rau arts thiab crafts.
Cov khoom nta: siab dawb, siab purity, siab refractoriness, zoo dispersibility thiab fluidity, thiab siab kwv yees Cov duab tuaj yeem hloov pauv yam tsis muaj qhov tawg, thiab cov duab tseem tuaj yeem khaws cia tom qab tshem tawm cov quab yuam sab nraud, thiab nws muaj kev sib sau zoo, drying thiab sintering zog.Cov khoom raug rho tawm haujlwm muaj cov yam ntxwv ntawm cov xim dawb, compactness, siab mechanical zog thiab siab yield.
