Kugwiritsa ntchito

Kugwiritsa ntchito pokonzekera mankhwala kapena njira zokonzekera:

Mowa wa polyvinyl umagwiritsidwa ntchito kwambiri pokonzekera zam'mutu komanso zamaso;

Polyvinyl mowa angagwiritsidwe ntchito ngati stabilizer mu emulsions.

Mowa wa polyvinyl umagwiritsidwanso ntchito ngati tackifier pokonzekera viscous monga mankhwala a ophthalmic.

Mowa wa polyvinyl umagwiritsidwa ntchito popaka mafuta m'misozi yokumba ndi ma lens olumikizirana, komanso amagwiritsidwa ntchito pokonzekera kutulutsa kwapakamwa komanso zigamba za transdermal.

Mowa wa polyvinyl ukhozanso kusakanizidwa ndi njira ya glutaraldehyde kupanga ma microspheres.
