Kev piav qhia txog khoom
1. Sab laug ntawm tus qauv qhia tau hais tias muaj cov qauv sab hauv xws li pob txha, cov leeg, cov hlab ntsha thiab cov leeg, ua kom yooj yim sib piv sab laug nrog sab xis thiab tsis txhob ua rau cov hlab ntsha thiab cov leeg puas tsuaj.
2. Koj tuaj yeem kuaj tau qhov chaw txhaj tshuaj rau hauv cov leeg kom raug.
3. Lub tswb ceeb toom thiab ob lub teeb ci ntsa iab yuav ceeb toom cov tub ntxhais kawm yog tias qhov chaw koob txhaj tshuaj tsis raug.
2. Koj tuaj yeem kuaj tau qhov chaw txhaj tshuaj rau hauv cov leeg kom raug.
3. Lub tswb ceeb toom thiab ob lub teeb ci ntsa iab yuav ceeb toom cov tub ntxhais kawm yog tias qhov chaw koob txhaj tshuaj tsis raug.
Cov yam ntxwv tseem ceeb:■ Tus qauv tsim uas pom tseeb qhia txog cov leeg nqaij, cov pob txha thiab cov hlab ntsha ntawm lub pob tw. Nws pab tau kom sib piv thaum lub sijhawm cob qhia thiab tiv thaiv kev tho qhov ntawm cov hlab ntsha thiab cov hlab ntsha. ■ Cov cim pob txha tuaj yeem kov kom paub tseeb tias qhov chaw txhaj tshuaj raug. ■ Kev txhaj tshuaj raug tuaj yeem ua rau cov kua txhaj tshuaj ntws mus rau hauv lub hnab ntim kua. ■ Yog tias kev txhaj tshuaj raug thiab qhov chaw txhaj tshuaj raug, yuav muaj lub teeb ntsuab; Yog tias qhov ntxig tob dhau lossis qhov chaw txhaj tshuaj tsis raug, yuav muaj lub teeb liab ntsais thiab lub suab ceeb toom hluav taws xob. ■ Cov khoom siv tawv nqaij yog ua los ntawm cov khoom siv yas elastomer uas xa tawm los ntawm txawv teb chaws, uas siv cov cuab yeej sib tsoo hlau tsis xeb ntawm qhov kub siab, xav tias cov qauv tiag tiag, ruaj khov, cov cim koob tsis pom tseeb.
