HPMC Hydroxypropyl Methyl Cellulose
Nānā huahana
?O ka HPMC kahi semi-synthetic nonionic cellulose i hui pū ?ia me ka pauka ke?oke?o a ke?oke?o paha. Ho?omākaukau ?ia e ka ho?ololi kemika o ka cellulose maoli.
Hiki ke ho?ohehe?e ?ia i loko o ka wai anuanu e hana ai i kahi hopena viscous akaka.
?ano huahana
?O ka mānoanoa maika?i: E ho?omaika?i nui i ka viscosity a me ke kūlike o ka wai, ho?omaika?i i ka wai a me ka pa?a.
Ho?okumu ki?i?oni?oni maika?i loa: Ke ho?omalo?o ?ia, ho?okumu ?ia kahi ki?i?oni?oni pa?akikī, ?o ia ka wai kūpa?a, hanu a ma?alahi.
Biocompatibility maika?i: ?A?ohe mea ?awa?awa, ?ono ?ole, ?a?ohe ho?onāukiuki, kūpono no ke kahua biomedicine.
Hiki ke ho?oha?aha?a i ke kaiapuni: Hiki ke ho?oha?aha?a i ke kaiapuni, e like me nā koi o ka palekana o ka'ōma?oma?o.
ho?ohana huahana
?Oihana kūkulu: Ho?ohana ?ia ma ke ?ano he mea mālama wai a me ka mea ho?opane?e o ka pahu sima e ho?omaika?i i ka ho?olaha a me ka manawa hana; Ma ke ?ano he mea ho?opili, ho?ohana ?ia e ho?opili i nā mea ho?onaninani e like me nā tile a me nā kinikini.
?Oihana ho?opili: Ma ke ?ano he mānoanoa, dispersant a me ka stabilizer, ho?omaika?i i ka hana o nā uhi.
Kahua lā?au lapa?au: Hiki ke ho?ohana ?ia ma ke ?ano he mea uhi ki?i?oni?oni, ho?oku?u ?ia ka mea ho?oku?u ?ia, nā mea pūpū capsule, kōkua ho?oku?u, etc.
?Oihana mea?ai: E hana ma ke ?ano he mānoanoa, emulsifier, stabilizer a me nā kuleana ?ē a?e.
Ka?ina hana hana
?O ka ma?amau ka pulupulu, ka lā?au e like me nā mea maka, ma o ka alkalization, propylene oxide a me chloromethane etherification ka?ina e ho?omākaukau ai.
Nā mana?o mākeke
Me ka ulu ?ana o ka ho?okele waiwai honua a me ka ?ike kaiapuni, ho?omau ka ulu ?ana o kāna koi mākeke. Ke ho?omau nei ka ho?onui ?ana o nā noi i nā hale ?ōma?oma?o, nā uhi pale kaiapuni, biomedicine a me nā māla ?ē a?e, a ke mana?o nei e ho?onui hou ?ia ka mākeke. Akā i ka manawa like, ke kū nei ka ?oihana i nā pilikia i ka ?enehana ?enehana, ka ho?okūkū mākeke a me nā koi o ka mālama ?ana i ke kaiapuni.
e ho?ohana i ka mālama ?ana
I ke ka?ina o ka ho?ohana ?ana, pono e ho?olohe i ke ?ano o ka ho?ohehe?e ?ana, a koho i ke ?ano dissolution kūpono e like me nā hi?ohi?ona like ?ole. I ka manawa like, e ho?olohe i nā kūlana mālama, pono e waiho i kahi malo?o, ma?ema?e ma?ema?e e hō?oia i ka maika?i o ka huahana a me ka hana.
