Phapano ke efe lipakeng tsa HPMC E5 le E15?

HPMC (Hydroxypropyl Methylcellulose) ke mofuta oa cellulose ether e sebelisoang lits'ebetsong tse fapaneng. Ke polima e se nang ionic, e qhibilihang ka metsing e nkiloeng ho selulose, 'me e sebelisoa e le ntho e teteaneng, emulsifier, stabilizer, le moemeli ea emisang. HPMC e fumaneha ka limaraka tse fapaneng, e 'ngoe le e 'ngoe e na le thepa ea eona e ikhethang. HPMC E5 le E15 ke tse peli tsa limaraka tse sebelisoang haholo tsa HPMC.

HPMC E5 ke kereiti e tlase ea viscosity ea HPMC, e nang le mefuta e mengata ea viscosity ea 4.0-6.0 cps. E sebelisoa mesebetsing e fapaneng, joalo ka likhomaretsi, likhomaretsi le li-sealants. E boetse e sebelisoa lits'ebetsong tsa lijo le tsa meriana e le setenya, se tsitsitseng le se emisang. HPMC E5 e qhibiliha ka metsing a batang le a chesang, 'me e lumellana le mefuta e mengata e fapaneng ea metsoako ea tlhaho.

HPMC E15 ke kereiti e phahameng ea viscosity ea HPMC, e nang le mefuta e mengata ea viscosity ea 12.0-18.0 cps. E sebelisoa mesebetsing e fapaneng, joalo ka likhomaretsi, likhomaretsi le li-sealants. E boetse e sebelisoa lits'ebetsong tsa lijo le tsa meriana e le setenya, se tsitsitseng le se emisang. HPMC E15 e qhibiliha metsing a batang le a chesang, 'me e lumellana le mefuta e mengata e fapaneng ea metsoako ea tlhaho.

Phapang e kholo pakeng tsa HPMC E5 le E15 ke viscosity. HPMC E5 e na le viscosity e tlase ho feta HPMC E15, ho bolelang hore ha e na viscous e nyane ebile e na le botsitso bo fokolang. Sena se etsa hore HPMC E5 e tšoanelehe hamolemo bakeng sa lits'ebetso tse hlokang botsitso bo fokolang, joalo ka lirafshoa le likhomaretsi. HPMC E15, ka lehlakoreng le leng, e na le viscosity e phahameng, e etsang hore e tšoanelehe hamolemo bakeng sa lits'ebetso tse hlokang ho tsitsisa ho hoholo, joalo ka li-sealants le lihlahisoa tsa lijo.

Ntle le phapang ea viscosity, HPMC E5 le E15 le tsona li fapane ka ho qhibiliha ha tsona. HPMC E5 e qhibiliha metsing a batang le a chesang, ha HPMC E15 e qhibiliha feela metsing a chesang. Sena se bolela hore HPMC E5 e ka sebelisoa lits'ebetsong tse hlokang tharollo ea metsi a batang, ha HPMC E15 e loketse hamolemo bakeng sa lits'ebetso tse hlokang tharollo ea metsi a chesang.

Qetellong, HPMC E5 le E15 le tsona li fapane ka ho tsamaellana ha tsona le metsoako ea tlhaho. HPMC E5 e tsamaisana le mefuta e mengata e fapaneng ea lihlapolli tsa tlhaho, ha HPMC E15 e sebetsa feela le mefuta e fokolang ea lihlapolli tsa tlhaho. Sena se bolela hore HPMC E5 e loketse hamolemo bakeng sa lits'ebetso tse hlokang mefuta e mengata e fapaneng ea lihlapolli tsa tlhaho, athe HPMC E15 e loketse lits'ebetso tse hlokang mefuta e lekantsoeng ea metsoako ea tlhaho.

Qetellong, HPMC E5 le E15 ke limaraka tse peli tse fapaneng tsa HPMC, e 'ngoe le e' ngoe e na le thepa ea eona e ikhethang. Phapang e kholo pakeng tsa bona ke viscosity, le HPMC E5 e nang le viscosity e tlaase ho feta HPMC E15. Ho phaella moo, HPMC E5 e qhibiliha metsing a batang le a chesang, ha HPMC E15 e qhibiliha feela metsing a chesang. Qetellong, HPMC E5 e lumellana le mefuta e mengata e fapaneng ea li-solvents, ha HPMC E15 e lumellana feela le mefuta e fokolang ea lihlahisoa tsa tlhaho.
