Thaum tshav kub kub hloov zaj duab xis yog cov khoom siv hluav taws xob hloov hluav taws xob los hloov cov qauv los ntawm cov khoom thauj mus rau saum npoo ntawm cov khoom siv. Nws yog dav siv rau kev kho kom zoo nkauj ntawm cov ntaub ntawv xws li hlau thiab yas. Nws lub hauv paus ntsiab lus tseem ceeb yog siv lub zog hluav taws xob los qhib cov xim molecules hauv txheej number case, ua rau lawv detach los ntawm cov cab kuj zaj duab xis thiab nkag mus rau hauv cov khoom nto, tsim cov qauv ruaj khov thiab meej. Cov thev naus laus zis no yuav tsum tsis muaj phaj ua, txhawb kev hloov kho tus kheej, thiab cov qauv hloov pauv yog hnav- tiv taus thiab corrosion- tiv taus, ua kom haum rau cov khoom lag luam kos npe, khoom plig tus kheej, thiab lwm yam xwm txheej.
Thaum tshav kub kub hloov zaj duab xis muaj lub hauv paus zaj duab xis, ib txheej tso tawm, txheej number case, thiab txheej nplaum. Lub hauv paus zaj duab xis muab kev txhawb nqa nqa, cov txheej txheem tso tawm tau cais tawm tom qab cua sov, txheej txheej number case muaj pigments thiab binders, thiab cov nplaum txheej yog lub luag haujlwm rau kev sib txuas rau cov khoom nto.
Cov txheej txheem hloov pauv muaj peb kauj ruam: ua ntej, zaj duab xis yog ua raws li cov khoom siv, thiab cov txheej txheem tso tawm yog sib cais los ntawm cua sov; Tom qab ntawd, cov kua nplaum txheej melts thiab nkag mus rau cov khoom nto; Thaum kawg, nws txias thiab solidifies, ua kom tiav cov qauv hloov. Tsawg-kub hloov tshuab (feem ntau qis dua 150 degree) zam kev puas tsuaj rau cov khoom los ntawm qhov kub thiab txias, ua rau nws tsim tshwj xeeb rau cov khoom siv thermal conductivity, xws li hlau.
