1. Soda-lime khob dej khob kuj yog lub khob dej ntau tshaj plaws hauv peb lub neej.Nws cov khoom tseem ceeb yog silicon dioxide, sodium oxide, thiab calcium oxide.Hom khob dej no yog tsim los ntawm kev siv tshuab thiab phau ntawv tshuab, tus nqi qis, thiab cov khoom siv txhua hnub.Yog tias cov dej qab zib-txiv qaub iav siv rau haus cov dej kub, nws feem ntau yuav tsum tau tempered thaum tawm hauv lub Hoobkas, txwv tsis pub lub khob yuav tawg yog tias qhov kub sib txawv loj heev.
2. High borosilicate iav dej khob, hom iav no muaj npe vim muaj cov ntsiab lus siab ntawm boron oxide.Cov tshuaj yej teev thiab cov tshuaj yej feem ntau siv los ua tshuaj yej tuaj yeem tiv taus qhov kub thiab txias hloov yam tsis muaj kev tawg.Tab sis hom iav no zoo li nyias, lub teeb yuag, thiab xav tias tsis zoo.
3. Crystal iav dej khob, hom iav no yog cov khoom lag luam qib siab hauv iav, vim tias nws muaj ntau yam hlau, nws qhov ntsuas tsis pom kev thiab permeability yog ze rau ntuj siv lead ua, yog li nws hu ua Crystal iav.Muaj ob hom siv lead ua iav, cov iav siv lead ua iav thiab cov iav tsis muaj hlau lead.Cov iav siv lead ua tsis pom zoo rau kev noj, tshwj xeeb tshaj yog tias koj haus cov dej haus acidic los ntawm lub khob dej, cov hmoov txhuas yuav yaj hauv cov kua qaub, thiab kev noj mus ntev yuav ua rau muaj kab mob lom.Lead-free crystals tsis muaj cov hlau lead thiab tsis muaj teeb meem rau lub cev.
