Dab tsi yog ceramic pigment

Ceramic pigment

Qeb:

Ceramic ceramic xim xa mus rau cov hmoov hlau oxides thiab lwm yam khoom siv hauv ceramic glazes, xws li hniav ceramics, porcelain, terra-cotta, thiab tseem nyob rau hauv porcelain enamel rau cov khoom hlau zoo nkauj. Thaum nyob rau hauv hmoov daim ntawv, feem ntau ceramic pigments yog tawm-dawb. Thaum ua haujlwm yog calcined hauv ceramic kilns lossis pottery kilns, lawv cov xim nplua nuj thiab ci ntsa iab tau tshwm sim. Ceramic pigments feem ntau muaj fluxes thiab cov khoom xyaw uas ua rau lawv nyuaj rau xim. Hauv tebchaws Askiv, ceramic pigments hu ua porcelain pigments.

Cov txheej txheem npaj

Quav hybrid

Qhov kawg xim ntawm cov xim muaj kev cuam tshuam zoo heev los ntawm kev sib ntxiv ntawm lwm cov khoom rau cov xim. Yog li ntawd, nyob rau hauv kev txiav txim rau txhua batch los tsim tib lub xim, nws yog tsim nyog los luj thiab sib tov ua tib zoo raws li cov khoom ntawm tib muaj pes tsawg leeg thiab zoo.

Quav lub calcination

Calcination yog txheej txheem tseem ceeb rau kev ua cov xim, thiab nws lub hom phiaj yog kom ruaj khov rau lawv. Thaum lub sij hawm calcination, cov tshuaj sib txawv tshwm sim vim muaj cov khoom sib txawv ntawm cov khoom siv raw thiab cov xim sib txawv uas xav tau. Qhov qis tshaj calcination kub yuav tsum yog tib yam li cov khoom kawg.

Folding dej los ntxuav

Tom qab calcination, cov xim yog crushed thiab ces ntxuav rau lub hom phiaj ntawm tshem tag nrho cov soluble tshuaj. Cov xim chromate yuav tsum tau ntxuav hauv dej kub. Yog tias muaj cov chromate soluble sab laug, yuav muaj qhov ntxoov ntxoo tsis sib xws nyob ib puag ncig chrome xim. Yog tias borate tsis raug tshem tawm, ib zaj duab xis yuav raug tsim tawm ntawm cov xim.

Folding daim

Tom qab ntxuav, lub fineness yuav tsum tau rau ntub sib tsoo yog tau los ntawm kev siv ib tug disc zeb los yog pob zeb. Txawm hais tias tsis muaj qhov xav tau tshwj xeeb rau qhov loj ntawm cov xim, cov kev cai dav dav yog tag nrho los ntawm 300 mesh screen. Kev sib tsoo tsis txaus yuav nyuaj rau kev siv vim qhov tsis sib xws ntawm cov nplej tsis sib xws thiab tsis muaj lub zog npog uas ua rau muaj qhov kub hnyiab. Ntawm qhov tsis sib xws, kev nplua nplua ntau dhau, xws li cov plua plav, tsis tuaj yeem ua kom tag nrho hauv cov glaze thiab ua qhov ua rau rolling glaze.

1. Vanadium Yellow khoom Series:

(Zr - V)

A. Lub glaze nrog zoo fluidity thiab siab boron cov ntsiab lus los yog cov ntsiab lus silicon tsawg qhia tau hais tias ci xim nyob rau hauv zirconium opalescent glaze;

B. Muaj pes tsawg ZnO nyob rau hauv glaze yog qhov zoo rau cov plaub hau xim;

C. Cov xim yuav tsum tsis txhob ua hauv av zoo heev thaum siv, txwv tsis pub nws yuav tsis muaj zog thiab ua xim.

2. Praseodymium daj Khoom series:

(Zr - Si - Pr)

A. Nyob rau hauv siab boron thiab tsawg silicon fusible glazes, xim yog ci thiab ci;

B. Cov xim hauv zirconium opacite glaze zoo dua;

C. Nws tuaj yeem pleev xim rau hauv txhua hom puag glazes.

3. Txiv kab ntxwv khoom Series:

(Ti-SB-CR) Qhov kub siv siab tshaj plaws yog 1280degree.

A. Nws yuav tsum tau siv rau hauv titanium glaze; txwv tsis pub, nws yuav hloov xim;

B. ZnO thiab SnO2 nyob rau hauv glaze yog qhov zoo rau kev tsim cov xim ntawm cov xim;

C. Tus nqi ntawm ZnO2 hauv glaze yuav tsum tsawg dua 10 feem pua, thiab cov ntsiab lus PbO yuav tsum tsawg li tsawg tau;

D. Tsis txhob sib tov nrog tin-muaj xim, lossis nws yuav hloov xim;

E. Haum rau kev tua hluav taws hauv oxidizing cua nkaus xwb.

4. Vanadium zirconium xiav khoom Series:

(ZR-SI-V) Qhov kev pabcuam siab tshaj plaws yog 1300degree. Peb cov khoom yog KL-003021 thiab KL-333021.

A. Nws muaj xim zoo tshaj plaws hauv zirconium opacified glaze;

B. Ntau dhau ntawm ZnO nyob rau hauv glaze yuav ua rau nws cov plaub hau xim ua ntiav;

C. Ntau dhau ntawm BaO nyob rau hauv glaze;

D. Ci xim hauv PbO glaze.

Daim ntawv thov

(1) Lub cev xim: sib tov cov xim thiab dawb paug kom lub cev tshwm sim xim tom qab hlawv.

(2) Glaze xim: xim tus neeg saib xyuas thiab lub hauv paus glaze tuaj yeem sib xyaw nrog ntau yam xim glaze thiab kos duab glaze.

(3) Kev kos duab zoo nkauj: nws yog dav siv rau kev pleev xim rau ntawm qhov chaw glaze thiab hauv qab glaze, thiab tseem tuaj yeem siv rau daim ntawv decal, tshuaj ntsuam luam ntawv, thiab lwm yam.

kev faib tawm

1. Ceramic pigments tuaj yeem muab faib ua:

Pigment tshaj glaze pigment nyob rau hauv glaze pigment nyob rau hauv glaze

Txhawm rau muab nws yooj yim, glazes yog ciam teb; Hauv qab glaze yog hauv qab glaze. Ib qho ntawm ob glazes yog glaze. Saum lub glaze yuav tsum yog lub glaze.

2. Kev faib tawm ntawm cov xim ceramic raws li cov theem ntxhia

3. Muaj hmoov thiab ceramic inks raws li lub xeev, uas yog, tus neeg sawv cev dej.
