Kugwiritsa ntchito

Kugwiritsa ntchito pokonzekera mankhwala kapena njira zokonzekera:

Mowa wa polyvinyl umagwiritsidwa ntchito kwambiri popanga mankhwala opaka mano ndi ophthalmic;

Mowa wa polyvinyl ungagwiritsidwe ntchito ngati chokhazikika mu emulsions.

Mowa wa polyvinyl umagwiritsidwanso ntchito ngati chomangira m'mafakitale okhuthala monga zinthu zopaka maso.

Mowa wa polyvinyl umagwiritsidwa ntchito popaka mafuta m'mabala opangidwa ndi ma contact lens, komanso umagwiritsidwanso ntchito popanga mabala otuluka m'kamwa komanso m'mabala otuluka pakhungu.

Mowa wa polyvinyl ungasakanizidwenso ndi yankho la glutaraldehyde kuti upange ma microspheres.
