Umhlinzeki we-Hydroxypropyl Methacrylate (HPMA) eNingizimu Afrika
I-monomer ye-HPMA esebenzayo yama-resin okumboza i-acrylic, izinhlelo ezilapheka nge-UV, izinto zamazinyo, kanye nama-hydrogel axhumene.

I-HPMA Ezimbozweni Ezisebenzayo kanye Nezicelo Ze-Biomedical
I-Hydroxypropyl methacrylate iyi-monomer ye-acrylic esebenza nge-hydroxyl ehlanganiswe kabanzi kuma-resins ezinhlelo zokumboza ezinezingxenye ezimbili ze-polyurethane kanye ne-melamine-crosslinked. Iqembu le-pendant hydroxyl liphendula ngama-crosslinkers e-isocyanate noma e-melamine ngesikhathi sokwelashwa, lakha ukumelana kwamakhemikhali kanye nokwemishini kwifilimu yokumboza. I-HPMA isetshenziswa futhi kuma-resin ahlanganisiwe amazinyo kanye nama-contact lens e-hydrogel, lapho ukuhambisana kwayo kanye nokuphiliswa kwamanzi kubalulekile khona.
Izidingo Zokuphakelwa kanye Nezochungechunge Olubandayo
I-HPMA iyavinjelwa futhi idinga indawo yokugcina epholile (8–20 °C) ukuvimbela ukupholisha ngaphambi kwesikhathi. I-Terracore ihlinzeka ngama-drum angu-25 kg kanye no-200 kg ngaphansi komoya we-nitrogen. I-COA ibika ukuhlolwa kwe-HPMA (GC), inani le-hydroxyl, inani le-asidi, kanye nokuqukethwe kwe-inhibitor. Kunikezwe ulwazi lwe-SDS olunengozi yokupholisha.
