Dab tsi kub tawm iav?

Qhov tsom iav sib txawv yuav plebntawm ntau qhov kub. Nov yog qee kis tshwj xeeb ntawm cov tsom iav feem ntau:
1. Dog iav
Cov iav zoo tib yam yuav tawg thaum qhov kub hloov los ntawm ntau dua 70 degrees Celsius.
Thaum qhov ntsuas kub txog 250℃-300 degree, zoo tib yam iav yuav yaj, tawg, lossis txawm tawg.
2. Tempered iav
Cov iav tempered tuaj yeem siv tau rau hauv qhov ntsuas kub ntawm -100 degrees Celsius mus rau 380 degrees Celsius. Thaum nws tshaj 380 degrees Celsius, cov khoom siv mechanical yuav maj mam poob. Thaum qhov ntsuas kub ncav ntau dua 300 degrees, tempered iav yuav tawg.
    3. High borosilicate iav
Cov cua sov -} tiv taus kub ntawm siab borosilicate iav yog tshaj li ntawm qhov kub thiab txias sib txawv ntawm "-30 txog 160 degrees Celsius".
4. Dej qab zib - kua qaub iav
Cov dej qab zib - kua qaub iav tsis tiv thaiv sai thiab cua sov, thiab tsuas tuaj yeem tiv thaiv qhov sib txawv ntawm 50 degree.
5. Crystal iav
Qhov ntsuas kub sib txawv tiv thaiv cov iav siv lead ua yog qhov nruab nrab, thiab nws tsuas tuaj yeem tiv thaiv qhov sib txawv ntawm 60 degree.
Nws yuav tsum tau sau tseg tias kev so ntawm lub khob tsis yog tsuas yog hais txog qhov kub thiab txias, tab sis kuj tseem yuav muaj ntau lub iav thickness, thermal conductivity, thiab niaj hnub sib xyaw. Piv txwv li, thaum tuab iav yog qhov yooj yim tawg vim yog tsis zoo thermal conductivity thiab kub kub sib txawv ntawm sab hauv thiab sab hauv thiab sab nraud txheej. Ntxiv rau, tsis xws luag nyob rau hauv cov txheej txheem tsim cov khoom siv ntawm cov khoom siv ntawm cov khoom siv iav, cuam tshuam sab nraud sab nraud, thiab lwm yam tuaj yeem ua rau khob tawg.
