Moetsi oa hypromellose ke mang?

Kima Chemical e fana ka lihlahisoa tse ngata tsa hypromellose ho finyella litlhoko tsa likopo tse sa tšoaneng. Lihlahisoa tsa k'hamphani tsa hypromellose li fumaneha ka limaraka tse fapaneng tsa viscosity le likhato tsa substitution (DS), hammoho le litlhophiso tse ikhethileng ho fihlela litlhoko tse ikhethang tsa bareki.

Lihlahisoa tsa hypromellose tsa Kima Chemical li etsoa ka theknoloji e tsoetseng pele ea tlhahiso le mehato e tiileng ea taolo ea boleng ho netefatsa boleng le ts'ebetso e tsitsitseng. Lihlahisoa tsa k'hamphani tsa hypromellose le tsona li lumellana le maemo a fapaneng a machaba, ho kenyelletsa USP, EP, JP, le FCC.

Hypromellose ke polymer e feto-fetohang e sebelisoang liindastering tse fapaneng. Kima Chemical ke moetsi ea ka sehloohong oa hypromellose, e fanang ka mefuta e mengata ea litekanyetso le litlhaloso ho finyella litlhoko tsa mefuta e fapaneng ea likopo. Lihlahisoa tsa hypromellose tsa Kima Chemical li etsoa ka theknoloji e tsoetseng pele ea tlhahiso le mehato e tiileng ea taolo ea boleng ho netefatsa boleng le ts'ebetso e tsitsitseng. Ka thepa ea eona e babatsehang le mefuta e mengata ea lisebelisoa, hypromellose ke motsoako oa bohlokoa lihlahisoa le liindasteri tse ngata.

Hypromellose, eo hape e tsejoang e le hydroxypropyl methylcellulose (HPMC), ke polymer ea semi-synthetic e sebelisoang liindastering tse fapaneng. E entsoe ka cellulose e fetolang lik'hemik'hale, polima ea tlhaho e fumanoang limela. Hypromellose hangata e sebelisoa e le setenya, emulsifier, le stabilizer indastering ea lijo, hape e le setlamo, sa pele sa filimi, le mafura indastering ea meriana. Kima Chemical ke moetsi ea ka sehloohong oa hypromellose, e fanang ka mefuta e mengata ea litekanyetso le litlhaloso ho finyella litlhoko tsa mefuta e fapaneng ea likopo.

Sebopeho sa lik'hemik'hale sa Hypromellose

Hypromelloseke polima e qhibilihang ka metsing e nkiloeng ho selulose. E entsoe ka ho arabela selulose ka propylene oxide le methyl chloride. Polymer e hlahisoang e na le boima ba limolek'hule ho tloha ho 10,000 ho ea ho 1,000,000 Daltons, ho itšetlehile ka tekanyo ea ho fetola (DS) le sehlopha sa viscosity.

Sebopeho sa lik'hemik'hale sa hypromellose se na le mokokotlo oa selulose o nang le hydroxypropyl le lihlopha tsa methyl tse khomaretsoeng likarolong tsa anhydroglucose. The degree of substitution (DS) e bolela palo e tloaelehileng ea lihlopha tsa hydroxypropyl le methyl ka unit ea anhydroglucose. DS e ka tloha ho 0.1 ho ea ho 2.5, ho itšetlehile ka thepa e lakatsehang ea hypromellose.

Lintho tsa Hypromellose

Hypromellose ke phofo e tšoeu ho isa ho e tšoeu e sa nkheng le e sa latsoeheng. E qhibiliha ka metsing le ka har'a metsoako e mengata ea tlhaho, empa ha e khone ho qhibiliha ka har'a metsoako e mengata ea nonpolar. Hypromellose e na le viscosity e phahameng maemong a tlase, e etsang hore e be motenya o matla le o tlamang. E boetse e na le thepa e babatsehang ea ho etsa lifilimi, e leng se etsang hore e be molemo ha ho etsoa liphahlo le lifilimi.

Thepa ea hypromellose e itšetlehile ka tekanyo ea ho fetola (DS) le sehlopha sa viscosity. Limaraka tse holimo tsa DS li na le ho qhibiliha ho hoholo ha metsi le mocheso o tlase oa gelation, ha limaraka tse tlase tsa DS li na le mocheso o phahameng oa mocheso le botsitso bo betere ba mocheso. Sehlopha sa viscosity se lekanya botenya ba tharollo ea hypromellose le bokhoni ba eona ba ho etsa li-gel.

Lisebelisoa tsa Hypromellose

Hypromellose e sebelisoa liindastering tse fapaneng, ho kenyelletsa lijo, meriana, litlolo le kaho. Indastering ea lijo, hypromellose e sebelisoa e le setei, emulsifier, le stabilizer lihlahisoa tse fapaneng, ho kenyelletsa ice cream, li-sauces le lintho tse halikiloeng. Indastering ea meriana, hypromellose e sebelisoa e le setlama, filimi-pele, le lubricant matlapeng, capsules, le mafura. E boetse e sebelisoa e le moemeli oa ho roala ka mokhoa o laoloang oa tokollo.

Indastering ea litlolo, hypromellose e sebelisoa e le ntho e tenya, e emulsifier le ea pele ea filimi ho etsa litlolo, litlolo le lihlahisoa tsa litlolo. Indastering ea kaho, hypromellose e sebelisoa e le sekontiri le se tlamang lihlahisoa tse entsoeng ka samente, tse kang seretse le li-grouts.
