6. Yuav ua li cas xaiv?
Yog tias koj daim ntawv thov yuav tsum muaj cov kua qaub ntau dua (xws li sulfuric acid, phosphoric acid) → Xaiv rau kev lag luam tshuaj (tsim nyog rau kev lag luam tshuaj).
Yog tias koj daim ntawv thov yog feem ntau se dej, kev kub siab chloride ib puag ncig → Xaiv rau cov marine engineering, kev hloov pauv cua sov).
Yog tias koj cov khoom siv yuav tsum tau muaj zog zoo dua thiab hnav tsis kam Xaiv S32760 (muaj zog cuam tshuam tawm) .
Yog tias yuav tsum muaj zog tshaj plaws muaj zog → Xaiv S32750 (me ntsis siab dua me ntsis lub zog) .
