Kuv xav muab txoj hauv kev rau koj los tsim cov qauv qub thiab kev lag luam ua kom zoo nkauj hauv 30 feeb.
Cov ntaub ntawv tsim nyog:
2 qag plastics, hlaws dai, qab zib, cov pos hniav.
Yas hom nrog rab riam rau ntawm cov khaub ncaws hnav, nyob ntawm cov yam uas xav tau ntau ntawm cov hlaws dai
Softening yas hauv tes thiab yob npas. Qab zib smear rau hauv lub hau, khiav hauv nws hlaws
Tom qab ntawd cov lus tsa suab nrov hauv xib teg peb cov khoom qab zib hauv cov hlaws dai rau cov qauv ntshiab
Ua kom cov hlaws dai nrog lub qhov tuab tuab ua qhov, du screing ntsia hlau lub koob thiab hais cov hlaws dai

Thaum cov hlaws dai yog qhuav ntxiv, peb coj lawv ntawm cov pos hniav, khi cov npoo mus rau hauv cov nodules, ntau dhau txiav tawm. Qhov ntawd yog txhua lub sijhawm tsawg kawg thiab cov nyiaj uas peb tau txais saws tes kom luag. Yog tias xav tau, nws tuaj yeem them nrog cov kua roj varnish rau cov tawv ntoo lossis xim ntsia hlau txhuam txhuam.
Vim muaj ntau yam xim, plastics thiab cov txheej txheem no koj tuaj yeem tsim cov teeb meem ci ntsa iab tshwj xeeb, ntawm piv txwv:
Ib qho chaw
