Nyob rau hauv xyoo tas los no, nrog rau kev kawm ntxiv ntawm cov pob zeb, nws pom tau tias cov npuas tau qhia thaum lub sij hawm sib xyaw ua vaj tse yog qhov laj thawj tseem ceeb rau cov pores sab hauv thiab ntawm qhov chaw ntawm cov pob zeb tom qab hardening. Tom qab sim ntxiv pob zeb defoamer, nws pom tias lub zog ntawm pob zeb tau nce ntau.
Kev tsim ntawm npuas yog tsim los ntawm kev sib xyaw ua ke. Cov huab cua tshiab nkag mus yog qhwv, thiab huab cua tsis tuaj yeem khiav tawm, yog li npuas tsim.
