Tiv tauj peb

Peb cov khiav hauj lwm rau tej hub frit tau ntau xyoo thiab peb muaj kev nplua nuj nyob hauv daim teb no kom koj zoo. Yog koj xav siv hauv cov khoom peb, qhia txog koj require (li firing kub, nws lub sij hawm thiab glaze nyhuv) tsis muaj hesitation. Peb yuav muab pub dawb xwb cov qauv rau kev tshuaj ntsuam koj. Kuj Engineers muaj nyob rau qhov kev pab cov neeg tuaj txawv tebchaw.

Tus thoob ntiaj teb kom muab kev koom tes nrog peb caw ua tsaug!

Ntau yam ntawm lub cev ntawm Vetrosa

Zibo Jinming Glaze Co., Ltd | Updated: Jun 19, 2017

Isotropic: cov txheej txheem ntawm cov iav ntawm molecular yog lus, thiab nws cov molecules muaj cov lus nrawm rau qhov chaw. Nyob rau hauv lub xeev uas zoo tshaj plaws, lub cev thiab cov khoom siv tshuaj (xws li kev ntsuas qis zog, qhov nyuaj, qhov ywj siab hloov, thermal expansion coefficient, thermal conductivity, hluav taws xob conductivity, thiab lwm yam) ntawm homogeneous iav yog tib yam hauv cov lus qhia.

Tsis muaj qhov taw rau lub cev: vim lub khob yog sib tov, amorphous, yog li tsis muaj qhov teeb meem ntawm lub cev melting. Cov iav los ntawm cov khoom ua kua yog ib yam kub (ie softening temperature range) yog qhov sib txawv, nws txawv ntawm cov ntaub ntawv crystalline, tsis muaj qhov taw tes rau lub cev qhuav. Softening kub ntau Tg ~ T1, Tg rau qhov hloov cov kub, T1 rau cov kua kub, cov viscosity coj los ua 1013.4 dPa · s, 104 ~ 6dPa · s.Vetrosa

Metastable: iav khoom yog feem ntau tau los ntawm kev txias txias ntawm yaj, los ntawm lub xeev lub cev mus rau lub iav hloov, qhov txheej txheem txias ntawm kev nce ceev hauv viscosity, qhov hais tsis tas yuav tsum ua tus txheej txheem ntawm cov ntxhuav, tsis tso lub latent heat of crystallization, Yog li, qhov iav muaj ib lub zog siab tshaj li cov khoom siv crystalline, thiab nws lub zog yog nruab nrab ntawm lub xeev thiab lub xeev crystalline, thiab belongs rau lub xeev metastable. Los ntawm cov neeg kho tshuab pom, lub iav yog ib qho tsis ruaj tsis khov-lub xeev, xws li lub neej ntawm lub zog tsawg-hloov hauv kev hloov, uas yog, qhov kev sib hloov crystallization, yog li ntawd iav yog ib qho khoom siv metastable.Vetrosa

Kev hloov maj mam rov qab: Cov txheej txheem ntawm cov khoom iav los ntawm lub cev ntawm lub cev mus rau hauv lub cev yog maj mam, thiab nws lub cev thiab cov khoom muaj zog kuj tseem nruam thiab maj mam. Qhov no yog qhov sib txawv ntawm qhov txheej txheem ntawm cov txheej txheem ntawm crystallization, cov txheej txheem crystallization yuav tsum yog ib theem tshiab, nyob ze ntawm qhov kev ntsuas kub ntawm crystallization, ntau cov khoom yuav tsum mutated. Thiab cov iav uas siv los ntawm lub raj tso rau hauv lub xeev yog ua kom tiav rau hauv qhov kub thiab txias, nrog rau qhov ntsuas kub tsawg, cov iav dawb viscosity maj mam nce, thiab thaum kawg tsim muaj cov iav, tab sis cov txheej txheem tsis tsim ib theem tshiab . Cov txheej txheem ntawm xa lub khob rau hauv yaj yog tseem gradual.Vetrosa
