1. Sodium thiab ntsev khob khob yog cov khob khob ntau tshaj plaws hauv peb lub neej.Nws cov khoom tseem ceeb yog silicon dioxide thiab sodium oxide thiab calcium oxide.Hom khob dej no yog ua los ntawm cov tshuab thiab phau ntawv tshuab, uas yog tus nqi qis thiab cov khoom siv hauv lub neej.Yog tias cov khob iav sodium thiab lipid siv los ua dej kub, nws feem ntau yuav tsum tau tempered thaum tawm hauv lub hoobkas, txwv tsis pub lub khob yuav tawg thaum qhov kub sib txawv loj heev.
2. High borosilicon iav, lub khob no muaj npe tom qab cov ntsiab lus siab ntawm boron oxide.Cov tshuaj yej teev thiab cov tshuaj yej uas siv nrog tshuaj yej tuaj yeem tiv taus kev hloov pauv ntawm qhov kub thiab txias sib txawv yam tsis muaj rupture.Tab sis lub khob no zoo li nyias, sib dua, thiab tsis zoo.
3. Crystal khob khob.Hom iav no yog cov khoom siv siab kawg hauv cov iav.Vim tias muaj ntau cov khoom hlau muaj, nws cov nyiaj cheb thiab pob tshab yog ze heev rau ntuj siv lead ua, thiab nws hu ua Crystal iav.Muaj ob hom siv lead ua iav, lead iav iav thiab lead-free crystal iav.Cov iav siv lead ua iav tsis pom zoo kom noj, tshwj xeeb tshaj yog rau haus cov kua qaub uas feem ntau siv.Cov hmoov txhuas yuav yaj rau hauv cov kua qaub.Kev noj mus ntev yuav ua rau muaj tshuaj lom neeg txhuas.Lead-free crystal tsis yog ib qho tseem ceeb thiab tsis muaj teeb meem rau lub cev.
