Vim li cas cov kub ntshiab tsis tuaj yeem tsim cov khob thermos

Cov kub ntshiab yog cov hlau muaj nuj nqis thiab tshwj xeeb. Txawm hais tias nws yog dav siv nyob rau hauv ntau yam hniav nyiaj hniav kub thiab handicrafts, nws tsis haum rau ua thermos khob. Cov hauv qab no yog ob peb lub hom phiaj vim li cas cov kub ntshiab tsis tuaj yeem siv los ua cov khoom siv rau thermos khob:

1. Softness thiab variability: Ntshiab kub yog ib tug kuj mos hlau nrog kuj tsis tshua muaj hardness. Qhov no ua rau cov khoom kub ntshiab muaj qhov cuam tshuam rau kev deformation thiab kev puas tsuaj, ua rau nws nyuaj rau kev tswj cov txheej txheem ruaj khov ntawm lub khob thermos. Thermos khob feem ntau yuav tsum tau tiv thaiv kev cuam tshuam, tee, thiab lwm yam thaum siv, thiab softness ntawm cov kub ntshiab tsis tuaj yeem muab kev cuam tshuam txaus.

2. Thermal conductivity: Cov kub ntshiab muaj cov thermal conductivity zoo, uas txhais tau tias nws tuaj yeem ua cua sov sai. Thaum ua lub khob thermos, peb feem ntau cia siab tias cov cua sov sab hauv tuaj yeem raug cais tawm kom tswj tau qhov kub ntawm cov dej haus. Txij li cov kub ntshiab muaj qhov muaj zog thermal conductivity, nws tsis tuaj yeem muab cov khoom siv thermal rwb thaiv tsev zoo thiab yog li tsis tsim nyog rau kev tsim cov thermos khob.

3. Tus nqi siab: Tus nqi thiab tsis tshua muaj hlau yog qhov txwv. Cov kub ntshiab yog cov hlau uas kim heev, thiab siv cov kub ntshiab los ua lub khob thermos yuav ua rau tus nqi ntawm cov khoom nce. Xws li tus nqi siab tsis tsuas yog ua rau cov khoom tsis yooj yim rau kev tsim khoom loj, tab sis kuj tsis ua raws li cov qauv siv niaj hnub thiab kev lag luam ntawm lub khob thermos.
4. Hlau reactivity: Cov hlau muaj qee yam reactivity, tshwj xeeb tshaj yog rau qee yam acidic. Thermos khob feem ntau yuav tsum tau tiv taus cov dej qab zib nrog cov pH sib txawv, thiab cov kub ntshiab yuav hnov ​​​​mob rau cov kua dej, cuam tshuam rau qhov zoo thiab kev nyab xeeb ntawm cov dej qab zib.

Txawm hais tias cov kub ntshiab muaj qhov tshwj xeeb hauv cov hniav nyiaj hniav kub thiab cov khoom siv kho kom zoo nkauj, nws cov khoom ua rau nws tsis haum rau kev siv hauv thermos khob. Rau cov thermos khob, peb cov kev xaiv ntau dua yog siv cov hlau tsis muaj steel, yas, iav thiab lwm yam ntaub ntawv, uas muab cov qauv kev ruaj ntseg zoo dua, thermal rwb thaiv tsev kev ua tau zoo, kev lag luam, thiab ua tau raws li kev siv tiag tiag.
