1. Cov ntsiab lus yooj yim ntawm cov kav dej yas
Cov kav yas yog cov kav dej ua los ntawm cov ntaub ntawv yas. Lawv yog lub teeb ci, corrosion - tsis kam, thiab yooj yim rau cov txheej txheem. Lawv siv dav siv hauv kev tsim kho, tshuaj lom neeg, tshuaj muaj tshuaj, hluav taws xob, kev sib tham, thiab lwm daim teb. Nyob ntawm cov kev siv sib txawv thiab cov kev xav tau, cov kev qhia tshwj xeeb ntawm cov kav dej yas kuj txawv.
