Granular glaze yog dab tsi?

Bulbous los yog irregular granular yog covcov khoom zoo tshaj plawsnyob rau hauv granular glazes.Qhov no hom ntawmgranular glaze tuaj yeem siv tsis tau tsuas yog nrog iav zoo li frits.Qhov glaze no kuj tseem siv tau nrog ntau hom frits uas tsim tshwj xeeb cov tshuaj tiv thaiv thiab cov khoom siv hluav taws xob zoo nkauj.Qhov no glaze kuj tuaj yeem siv ua ke nrog cov glaze tsim los ntawm raw cov ntaub ntawv. Ntau yam khoom sib xyaw.Rau cov khoom sib xyaw uas muaj ntau yam frits thiab cov khoom siv raw, nws tseem tuaj yeem ua ke rau hauv ib qho ruaj khov, ntom, txawm tias granular zoo li.Cov txheej txheem ntawm kev ua granular glazes yog raws li nram no:Starting nrog ib tug complex glaze formula, txhua raw khoom yog finely hauv av (ntub los yog qhuav) kom ua tau zoo uniformity thiab fineness.

Tom qab ntawd cov khoom xyaw yog tov thiab cov hmoov yog granulated los ua ib qho nyuaj los yog spherules (wetting agents thiab binders).

Granulation tuaj yeem ua tiav los ntawm ntau hom granulator, uas tuaj yeem tsim tau 0.5 ~ 10mm pellet.Lwm cov tshuab kuj muaj.Piv txwv, siv hmoov qhuav nias lossis extrusion hauv molded daim ntawv.

Kom tau txais spherulite compactness, tshuaj additives thiab ziab ntxiv yuav siv tau rau sintering ntawm 600-800 degree .Yog hais tias cov particle loj dhau lawm, lub crusher yuav siv tau rau crushing, thiab ces tshuaj ntsuam.

Qhov no granular glaze yuav tinted nyob rau hauv nws formulation los yog coated nrog ib tug colourant.Granular glaze nyob rau hauv ceramic kho kom zoo nkauj tuaj yeem tsim ib qho frit glaze ntau dua,qho uaNws tsis tshwm sim unmelted thiab refractory hais raws li fritted glazes ua.Nws ua ib tug mos, du glaze. Pigments thiab glazes diffuse mus rau hauv cov khoom nyob ib puag ncig.Cov glaze hais rov siv duarautsim cov hlab ntsha vim muaj ntau txheej txheej thiab sib txawv melting degree ntawm cov khoom. Yog linws ua tauenhancelos yog reducecov nyhuv ntawm cov xim.Granular glazes tuaj yeem tsim cov teebmeem xws li zaj sawv glazes, crystalline glazes, matt glazes thiab rustic glazes.

Tsis tas li ntawd, cov iav txheej tsim tom qab melting thiab firing muaj ib tug zoo ntom thaum lub grainy glaze yog formulated kom zoo.
