HPMC, kapa hydroxypropypropinyl methylcelulose, ho kopanyelletsa le meriana, lijo, kaho, lijo le litlolo. Ho utloisisa bophelo ba eona ba sefifi sa eona ke sa bohlokoa bakeng sa ho netefatsa boleng ba sehlahisoa, ho atlehile le polokeho.
1.Ke hpmc ke hpmc?
Hydroxypropypropypropinyl methylcelllulose (HPMC) ke polymer ea synthetic e tsoang cellulose. E sebelisoa hangata e le moemeli ea halefileng, Stabilizer le filimi e hlahisitsoeng ka lebaka la eona e ikhethang, ho kenyeletsoa lencelity ka metsing, le liketsahalo tse seng tsa Iona tsa khethollo, le pono e phahameng. HPMC hangata e khetholloa ka polymers tse ling ka lebaka la sejo se seng sa biodegrada, e seng chefo, 'me ho lumellana le metsoako e mengata ea litlatsetso le metsoako.
Tsela ea HPMC
Bophelo ba HPMC bo ka fapana ho latela maemo a 'maloa, ho kenyeletsa le maemo a polokelo, le ho pepesetsoa lintho tsa kantle joalo ka mongobo, khanya le mocheso. Ka kakaretso, HPMC e na le bophelo bo bolelele ba sehatsetsing ha bometsoe hantle, hangata bo tloha ho bo bong ho isa ho tse tharo ho tloha ka letsatsi la tlhahiso.
3.Loane e amang bophelo ba sehatsetsing
Maemo a polokelo: Ho boloka ka nepo ho bohlokoa bakeng sa ho boloka botsitso ba HPMC. E lokela ho bolokoa sebakeng se pholileng, se omileng hole le khanya e tobileng ea khanya ea letsatsi le mocheso. Ho pepesetsoa lithemparetjha tse phahameng le mongobo o ka eketsa litšila le ho fokotsa bophelo ba sehatsetsing.
Ho paka: HPMC e fumaneha hangata ka lijana kapa mekotleng ea ho e sireletsa ho tloha mongobo le lithipa. Ho paka boleng ba boleng ho ka holisa bophelo ba Sheffeng ka ho thibela ho pepesetsoa mabaka a kantle.
Boea: Psyity ea HPMC e ka susumetsa botsitso ba eona le sehatsetsing. Masira a Pholohileng a Purity a tloaetse ho nyonyehang 'me a ka ba le bophelo bo bolelele ba sekhechana ha bo bapisoa le limaraka tse tlase tsa purity.
Ho pepesetsoa mongobo: HPMC ke hygroscopic, ho bolelang hore e utloisise mongobo sebakeng se haufi. Ho pepesetsoa mongobo ho ka lebisa ho khokhothela, ho lahleheloa ke phallo, le polymer, ho fokotsa bophelo ba bona ba sehatsetsing.
Ho pepesetsoa ha bobebe: Ultraviolet (UV) radiation ho tsoa letsatsing la khanya ea letsatsi kapa mehloli ea maiketsetso e ka nyenyefatsa Hpmc ha nako e ntse e tsamaea. Ho paka ka nepo ho ka thusa ho boloka boleng ba eona le ho holisa bophelo ba sehatsetsing.
Ts'ebetso ea lik'hemik'hale: HPMC e ka sebelisana le lintho tse ling tse teng tikolohong ea eona, e kang lik'hemik'hale, li-solvel, li lebisang ho litšila le ho fokola bophelong.
Litlhahiso tsa 4.Stolola
Ho eketsa bophelo ba sehatsetsi ba HPMC, nahana ka litlhahiso tse latelang tsa polokelo:
Boloka sebakeng se pholileng, se omileng: boloka lijana tsa HPMC li tiisitsoe ka thata ebe u li boloka sebakeng se pholileng, se omileng ka mocheso o phoroselang le maemo a hulling.
Sireletsa ho tsoa ho Leseli: Boloka HPMC hole le khanya ea letsatsi kapa mehloli ea mahlaseli a UV ho thibela ho nyopa.
Qoba ho pepesetsoa mongobo: Fokotsa ho pepesetsoa mongobo ka ho boloka lijana li tiisitsoe ka thata le ho li boloka mobung tikolohong e omileng.
Latela likhothaletso tsa moetsi: Ho latela tataiso ea moetsi mabapi le maemo a marang-rang, bophelo ba sengoli, le ho sebetsana le litloaelo ho netefatsa boleng ba sehlahisoa.
Sebelisa Fifico (Pele, ho ea pele)
Lifefo tsa 1Ex
Ha HPMC hangata e na le bophelo bo bolelele ba sehatsetsing, mekhoa e itseng e ka thusa ho e fetisetsa ho feta:
Desiccants: Sebelisa Desciants e kang silica ea silica ea silica
Ho khothaletsa Hermetic:
Taolo ea mocheso: Kenya lits'ebeletso tse laoloang ke mocheso ho boloka maemo a phomolo a ho boloka le ho thibela ho pepesetsoa mochesong o phahameng.
Tlhahlobo ea khafetsa: Ho hlahloba nako le nako ho bolokoa HPMC bakeng sa matšoao a ho khatholla, joalo ka ho khomarela, ho lahla lihlopha tse fapaneng.
Ho sebetsana ka nepo: sebetsana le HPMC ka tlhokomelo ea ho qoba tšilafalo le tšenyo ea ho paka, e ka sekisetsa sehlahisoa sa boleng ba sehlahisoa le se sekhutlo sa sehlahisoa.
Hydroxypropypropypropinyl methylcelllulose (HPMC) ke polymer e sa fetoheng e nang le likopo tse ngata ho indastering e fapaneng. Ho utloisisa bophelo le lintlha tse amang tsitsipano ho bohlokoa bakeng sa ho netefatsa boleng ba sehlahisoa, ho sebetsa hantle le polokeho. Ka ho latela mekhoa e nepahetseng ea polokelo, ho latela litlhahiso tsa moetsi, le maano a ho fokotsa bophelo bo litšila, ho ka etsahala hore o tsebe ho phela hape.
