Lub tshuab txias dov ua haujlwm tseem ceeb hauv kev ua hlau, hloov cov ntaub ntawv raw rau hauv cov khoom tiav nrog cov khoom zoo. Nws lub luag haujlwm tseem ceeb yog txo cov thickness ntawm cov hlau xws li hlau, txhuas, thiab tooj liab los ntawm kev hla lawv los ntawm cov yob hauv qab qhov tseem ceeb ntawm chav tsev kub.
Cov txheej txheem no tsis tsuas yog hloov cov duab thiab qhov loj ntawm cov hlau, tab sis kuj txhim kho nws lub cev thiab cov yam ntxwv ntawm txhua yam. Txias dov refines lub grain qauv, ua rau kom muaj zog hardness, lub zog, thiab zoo dua dimensional raug. Nws kuj tseem txhim kho qhov chaw tiav, ua kom zoo dua thiab muaj kev cuam tshuam ntau dua.
Tsis tas li ntawd, txias dov yog ntau zog-npaum thiab ib puag ncig tus phooj ywg piv rau kub dov, vim nws tshem tawm qhov xav tau rau reheating hlau. Qhov no ua rau nws yog ib qho cuab yeej tseem ceeb hauv kev tsim khoom niaj hnub, ua kom muaj cov khoom zoo, precision-engineered Cheebtsam rau ntau yam kev lag luam.
