Cov txheej txheem ntawm kev ua lub raj mis. Flat iav yog tsim los ntawm kev dov mus tas li. Cov txheej txheem cuam tshuam nrog qhov tseeb tias cov kwj ntawm cov iav molten los ntawm lub cub tawg tsis tu ncua nkag mus rau qhov chaw nruab nrab ntawm cov rotating rollers hauv qhov cub, qhov twg nws dhau los ua daim kab xev. Ua li no, ntau hom iav tuaj yeem tsim tau.
Nruam dov txoj kev ntawm siab dawb iav fwj manufacturers
Cov theem tom ntej tom qab ua tiav yog annealing, iav toughening thiab kev kho cua sov. Annealed molded thiab tseem kub cov khoom siv los tiv thaiv qhov tsis sib xws ntawm qhov nro ntawm qhov tshwm sim. Qhov no yog qhov tseem ceeb hauv kev tsim cov iav fwj, vim qhov no ua rau lawv lub zog thiab tso cai rau kom tsis txhob muaj kev pheej hmoo ntawm kev sib cais thaum lawv siv. Toughening ntawm iav yog kev ua haujlwm, tsis zoo li annealing. Toughened khoom yog thermally thiab mechanically ntau ruaj. Ntawm cov txiaj ntsig toughened, shatter-resistant iav tuaj yeem tau, uas yog siv tsis tau tsuas yog rau kev tsim cov fwj, tab sis kuj rau glare nyob rau hauv lub qhov rais ntawm lub tsheb thiab dav hlau (Olavi). Yuav kom khov lub iav, nws yog rhuab mus rau 600 degree - 650 degree, ces nws txias sai heev. Tom qab ntawd, kev kho cua sov ntawm lub khob yog tsim nyog yog tias lawv tuaj yeem ua tau.
Ntau tus ntseeg tias peb lub xyoo pua yuav raug hu ua Hnub Nyoog ntawm iav. Iav tau siv los ntawm tib neeg rau ntau pua xyoo, tab sis cov txheej txheem ntawm nws cov creation tseem txaus nyiam thiab txawm me ntsis mysterious. Iav tsis tsuas yog tiv thaiv peb lub tsev los ntawm txias thiab cua, tab sis kuj tsim kom yooj yim heev thaum siv nyob rau hauv lub neej txhua hnub.
