Cov hlaws dai ntab yog ib hom khoom siv tshiab. Nyob rau hauv xyoo tas los no, nrog rau kev tshawb fawb tob zuj zus, tib neeg paub ntau ntxiv txog cov yam ntxwv ntawm cov hlaws dai ntab, thiab daim ntawv thov ntawm cov hlaws dai ntab hauv ntau qhov chaw yog qhov dav dua.

Tom ntej no, cia peb saib cov haujlwm thiab cov haujlwm ntawm cov hlaws dai ntab. Feem ntau hais lus, cov hlaws dai ntab yog lub teeb yuag, nrog phab ntsa nyias thiab khoob hauv nruab nrab. Txawv ntawm cov tshauv ya dav hlau ib txwm muaj, cov hlaws dai ntab muaj cov thermal conductivity qis, tsis muaj kev phom sij hluav taws los ntawm kev hlawv, thiab lawv kuj tiv taus hluav taws heev, tiv taus cua sov, thiab tuaj yeem khaws cia rau hauv qhov chaw kub siab. Yog li ntawd, ntau lub tuam txhab tsim khoom siv cov hlaws dai ntab ua cov khoom rwb thaiv tsev thermal thiab cov khoom tiv taus hluav taws, uas yog thawj qhov haujlwm ntawm cov hlaws dai ntab.

uas kuj yog ib qho kev ua haujlwm sib xws. Muaj, cov hlaws dai ntab, vim nws cov khoom tshwj xeeb, kuj tuaj yeem ntxiv rau cov xim thiab xim, qhov no yog vim peb cov hlaws dai ntab yog kheej kheej, txawm li cas los xij, thaj chaw kheej kheej me me, yog li rau cov xim lossis cov txheej uas xav tau cov resin, yog tias cov khoom no hloov pauv, nws yuav txuag tau tus nqi, thiab peb cov khoom khov kho siab thiab cov ntaub ntawv VOC qis tuaj yeem hloov pauv tib lub sijhawm, cov khoom no kuj muaj lub zog siab, uas tuaj yeem siv rau ntau yam kev siv roj drilling, thiab tuaj yeem siv ua castable ntau lawm.
