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!

Cov Cim Ntawm Cov Vetrosa

Zibo Jinming Glaze Co., Ltd | Updated: Jun 08, 2017

Cov iav yog tsim los ntawm silica thiab lwm yam tshuaj siv tshuaj ua melted ua ke (qhov tseem ceeb ntawm cov khoom siv raw: soda tshauv, limestone, quartz). Nyob rau hauv lub melting ntawm tsim ntawm ib tug network txuas nruam, lub viscosity ntawm tus txheej txheem maj ntau zog thiab hardened los ua lub crystallization ntawm silicate non-metallic cov ntaub ntawv.Vetrosa

Cov tshuaj lom neeg muaj pes tsawg lub iav yog Na2SiO3, CaSiO3, SiO2 los yog Na2O · CaO · 6SiO2, thiab lwm yam., Lub ntsiab tivthaiv yog ntsev ntsev, yog ib hom qauv amorphous ntawm amorphous khoom. Siv dav hauv cov tuam tsev, siv teeb pom los ntawm lub teeb, zwm rau qhov sib tov. Cov kob dawb lias muaj xim los yog ntsev, thiab lub khob iav uas tau los ntawm lub cev los yog tshuaj lom neeg. Qee lub sij hawm qee cov pob tshab yas (xws li polymethylmethacrylate) kuj muaj lub npe hu ua cov lus tsis zoo.

Lub txheej txheem ntawm cov iav ntawm molecular yog tsis meej, thiab nws cov molecules muaj cov lus tsis muaj teeb meem nyob rau hauv 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 khob yog tib yam nyob rau hauv tag nrho cov lus qhia.

Vim hais tias lub iav yog sib tov, tsis yog-crystalline, 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

Cov teeb meem iav yog feem ntau tau los ntawm qhov txias txias ntawm lub yaj, los ntawm lub xeev lub cev mus rau lub iav hloov, qhov txheej txheem ntawm kev nce ceev ceev hauv viscosity, qhov loj yog lig dhau los ua ib qho kev npaj tsim cov nplais, tsis tso cov cua sov ntawm crystallization, yog li ntawd, iav Cov quav tshuaj muaj zog dua li cov khoom siv crystalline ntau dua, thiab nws lub zog yog nruab nrab ntawm cov roj ntsha hauv lub xeev thiab lub xeev lub xeev, thiab belongs rau lub xeev tau pom. 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
