Maʻemaʻe kiʻekiʻe 99% PVP/Polyvinylpyrrolidone
Huahana Huahana
ʻO ka PVP (polyvinylpyrrolidone) he polymer hiki ke hoʻoheheʻe wai me nā waiwai hana kiʻiʻoniʻoni. Hoʻohana nui ʻia ia i ka lāʻau lapaʻau (e laʻa me ka plasma volume expander a i ʻole nā lens pili). ʻO K-90 (111.14 g/mol) ka paona molekala.
Nā pōmaikaʻi
- ʻO ka mea hana mānoanoa kūpono a me ke kiʻiʻoniʻoni mua no nā gel lauoho, nā lauoho lauoho a me nā pauka a me nā gels
- Ua kaupalena ʻia ka pae hoʻohana e ka viscosity wale nō
- Paʻa loa ka pH, non-ionic a me ke kala ʻole
- ʻOi aku ka maikaʻi ke hui pū me ka carbomer a i ʻole nā mea mānoanoa ʻē aʻe e hāʻawi i ka paʻa paʻa i nā gel lauoho
- Hoʻohana ʻia ma ke ʻano he dispersant no ka titanium dioxide a me nā pua puaʻa
Hoʻohana
ʻO ka pae hoʻohana maʻamau 1-40%, ma kahi o 4-7% i nā gels lauoho. E hoʻohui i ka wai o nā formulations, hydrate a laila hui maikaʻi. No ka hoʻohana waho wale nō.
Nā noi
ʻO nā huahana mālama lauoho, nā kiʻiʻoniʻoni adhesive e hana ana i nā gels, nā mea hoʻonaninani kala.
