Cov txheej txheem ua haujlwm ntawm tsev neeg cov ntawv ci tau kub yog tsuas yog ua raws li cov khoom siv lub cev thiab tsim qauv ntawm txhuas ntawv ci.
Aluminium ntawv ci yog daim nyias nyias ua los ntawm cov txheej txheem ntawm cov txheej txheem ntawm cov hlau aluminium. Thaum lub sij hawm cov txheej txheem ntau lawm, txhuas ntawv ci feem ntau yog siv rau kev puas tsuaj thiab txuag tau kom yooj yim rau yob thiab tsis yooj yim tawg. Tsis tas li ntawd, saum npoo ntawm txhuas ntawv ci tau kho tshwj xeeb thiab muaj qee qib ntawm adhesion, yog li nws tuaj yeem haum kom nruj thaum xoob xoob.
