Fa'aogaina ole alava PVA ile sima

Fa'amatalaga:

O alava Polyvinyl alcohol (PVA) ua tula'i mai e avea o se fa'aopoopo fa'amoemoeina i tekonolosi sima, e fesoasoani i le fa'aleleia atili o mea tau masini ma le tumau. O lenei iloiloga faʻapitoa e suʻesuʻeina ai aʻafiaga o le tuʻufaʻatasia o filo PVA i faʻafefiloi sima, faʻatalanoaina a latou meatotino, gaosiga o gaosiga, ma faʻaoga eseese i le fale faufale. Talanoaga e aofia ai a'afiaga o alava PVA i mea fou ma malo o le sima, o latou matafaioi i le puipuia o ta'e, ma le aoga o le siosiomaga e feso'ota'i ma lo latou fa'aogaina. E le gata i lea, o luʻitau ma faʻamoemoega i le lumanaʻi o loʻo faʻamaonia e taʻitaʻia atili suʻesuʻega ma atinaʻe i lenei matata.
