Yuav Ua Li Cas Thiaj Yuav Ib Lub Khob Dej Dej Zoo?
Dec 29, 2023
- Saib xyuas cov ntaub ntawv
Cov khoom siv iav muaj xws li dej qab zib-txiv qaub, tempered borosilicate iav, siv lead ua (tiav / lead-dawb) iav, thiab nws muaj kev nyab xeeb tshaj plaws los xaiv cov iav borosilicate siab.
2. Saib xyuas qhov tuab.
Cov iav zoo tshaj plaws, lub thickness ntawm lub khob lub cev yog tuab, thiab lub thickness ntawm lub hauv qab ntawm lub khob yog thicker tshaj lub khob lub cev, uas yog feem ntau tsis yooj yim rau tawg thiab muaj ib tug zoo thermal tiv thaiv nyhuv.
3. Saib xyuas pob tshab/kev xa tawm
Lub iav zoo zoo yuav tsum tsis pub muaj impurities thiab tsis pom cov iav me me. Cov tsom iav tsis zoo muaj lub teeb xa hluav taws xob tsis zoo, qhov muag plooj thiab impurities.
4. Saib cov npuas.
Lub khob zoo tsis pub muaj npuas, yog tias muaj npuas lossis muaj npuas ntau, nws feem ntau yog cov khoom siv tsis zoo / cov txheej txheem qis, nws tsis yog.
5. Saib xyuas qhov roundness thiab thickness ntawm lub khob.
Yog hais tias nws tsis yog ib qho tshwj xeeb-zoo li lub khob, xyuas lub roundness ntawm lub khob lub qhov ncauj thiab hauv qab ntawm lub khob, seb nws yog zoo kawg nkaus puag ncig, lub khob lub qhov ncauj tsis round ntawm thickness yog txawv, tsis pom zoo kom xaiv mus yuav.
6. Xaiv lub iav ob chav phab ntsa.
Ob chav phab ntsa iav khob tsis tsuas yog muaj cov nyhuv thermal rwb thaiv tsev xwb tab sis kuj tsis kub, yooj yim siv, yog tias ob chav phab ntsa iav thiab lub khob thermos muaj cov nyhuv tib yam, tsis txhob ntseeg nws.
7. Tshawb xyuas daim ntawv pov thawj thiab cov ntaub ntawv tseem ceeb.
Lub Hoobkas tsis tu ncua tsom iav muaj daim ntawv pov thawj thiab cov lus qhia, kom pom seb nws puas yog iav zoo tib yam lossis borosilicate iav, nws raug nquahu kom xaiv iav borosilicate.
8. Puas muaj ntxhiab tsw.
Lub khob khob uas tsim los ntawm cov chaw tsim khoom tsis tu ncua, feem ntau yuav muaj ntxhiab tsw, qee qhov chaw tsim khoom yuav ntim tshuaj yej hnab los npog cov ntxhiab tsw, ua haujlwm zoo ntawm kev sib txawv.
