Kana uchisarudzaHydroxyprupyl methylcellose (HPMC).
1. Molecular chimiro uye suremu hwemanyorerwe
Iyo srea uremu hwesimba rekusimba Kazhinji, yakakwira iyo smecular uremu hweHPMC, zvirinani kuchengetwa kwemvura. HPMC ine yakakura molecular uremu iine cheni refu cheteni, iyo inogona kutora yakawanda mvura uye inogadzira imwe yakagadzikana glable gel chimiro.
Yakakwira Molecular uremu Hpmc: Ine yakaderera salubility mumvura, asi inogona kuita zvirinani kuti mvura idzo dzidzo dzive dzekuchengetedzwa kwemvura, sekuvaka marara, etc.
Low Molecular uremu Hpmc: Kudzokorora kwemvura kwemvura, asi zviri nani flidiity, zvakakodzera kune mafambiro anodikanwa kukurumidza kusimbisa kana kukurumidza kuoma.
2. Hydroxyprupropyl zvemukati
HydroxyPropyl zvemukati zvinoregedza kune zvemukati zveHydroxyprupyl mapoka muHPMC mamorekuru, kazhinji inoratidzwa sehuwandu hwehuwandu. Zviri mukati mehydroxypropropyl inobata iyo solubility, viscosity uye kuchengetwa kwemvura kweHPMC.
Yakakwira HydroxyPropyl Zvemukati HPMC: Inogona kuve iri kunyungudutswa mumvura uye nekuwedzera hydration, saka kuve nekuchengetwa kwemvura kuri nani uye kunonyanya kukodzera kushandiswa munzvimbo dzakakwirira dzinonyadzisa.
Low HydroxyPropropyl Zvemukati HPMC: Solvous Solubility, asi inogona kuve nekwakakwirira viscosity, iyo yakanyanya kukodzera mune mamwe mashandisirwo akadai seyakagwinya.
3. Solubility
Iyo solubility yeHPMC ndechimwe chezvinhu zvakakosha pakutonga kuchengetwa kwemvura kwayo. Yakanaka solubility inobatsira kuti ibviswe zvakanyanyisa mumvura, nekudaro ichishandisa simba rekuchengeta mvura iri nani.
Kudziya kwemvura solubility: Mazhinji hpmcs anodzikisira mumvura inodziya. Iyo yakanyungudika hpmc inogona kuumba mhinduro ye collodal, iyo inobatsira kuti igare yakanyorova mumasimende slurry uye inodzivirira mvura kubva mukubuda nekukurumidza.
Kutonhora kwemvura solubility: Zvezvigadzirwa zvinoda kushandiswa munzvimbo dzakaderera tembiricha, HPMC nekuisa pasi kutonhora kwemvura solubility kwakanyanya. Rudzi urwu rweHPMC inogona kunyungudika nekukurumidza pamhepo tembiricha kana tembiricha yakaderera kuti ive nechokwadi chekuchengetwa kwemvura panguva yekuvaka.
4. Particle saizi kugoverwa
Iyo size yehukuru hweHPMC yakanangana neyekurovera kwayo kwemvura uye nekuchengetwa kwemvura. HPMC ine zvidimbu zvidimbu zvinopera nekukurumidza uye zvinogona kukurumidza kusunungura mvura muhurongwa, nekudaro uchisimudzira kuchengetedza kwemvura. Kunyangwe HPMC ine zvidimbu zvakakura zvichidonha zvishoma nezvishoma, inogona kuumba hystem yakagadzikana muhurongwa, saka kuchengetwa kwemvura kwakanyanyisa.
Gadzira zvakanaka HPMC: Yakakodzera maZviratidzo zvinoda kukurumidza kupera, inogona kusunungura mvura nekukurumidza, uye yakakodzera zvigadzirwa zvakaita kunge madhiri akaoma-akasanganiswa anoda hydration yekutanga.
Coarse Chishamiso Hpmc: Yakanyanya kukodzera mune zviitiko zvinoda kuchengetwa kwenguva refu kwemvura, senge simendi refu-refu-refu slurry, mabhendi ekuvaka, nezvimwe.
5. Zvinyorwa zvinyoro
Iyo yakanyorova yeHPMC ichakanganisawo mari yayo yekuchengetwa kwemvura. Kunyanyisa kunyorova kunogona kukonzera HPMC kuti ichinje chekuita kwayo panguva yekuchengetedza uye kushandiswa. Naizvozvo, hpm cless inowanzo kuve nehupenyu hwakareba hwesherufu uye zvakanyanya kugadzikana kuita. Kana uchisarudza, teerera kune yayo yakanyorova yekunyorovera kuti udzivise kunyorova kunyengedza kunokanganisa maitiro ekushandisa.
6. Tembiricha kuramba
Kuchengetwa kwemvura kweHPMC kwanyatsoenderana neyakaipisa kupisa kwetembiricha. Zvimwe zvinoshandiswa zvinogona kuda hpmc kuti uchengetedze hydration yakagadzikana pakupembera kwakakwirira. Semuenzaniso, kukosva midziyo kungangoda kushandiswa pakupisa kwakanyanya panguva yekuvaka. Kusarudza HPMC ine simba rekushisa kunogona kuve nechokwadi chekuchengetwa kwemvura panguva yekuvaka uye kudzivirira izvo zvekupisa nekukurumidza nekukurumidza.
7. Kugadzikana
Kugadzikana kweHPMC kuchakanganisawo kuchengetwa kwemvura kwaro pasi pemamiriro akapatsanurwa akapedzana. Yakagadzikana HPMC inogona kuchengetedza kudzokorora kwemvura kwenguva yakareba munzvimbo dzakasiyana siyana, kunyanya mune yakasimba alkaline kana nharaunda dzakarongeka dzakadai simende kana gypsum. Izvo zvakakosha kusarudza HPMC nekusimba kwakasimba. Kana iyo makemikari kugadzikana kweHPMC iri murombo, kuchengetwa kwemvura kwaro kunogona kuderera nekufamba kwenguva, kukanganisa kuita kwekupedzisira.
8. Kuwedzera uye pamusoro pekurapwa
Mamwe zvigadzirwa zveHPMC anowedzera zvimwe zvakakosha zvekurapa kana zvinowedzera zvinowedzera panguva yekugadzira maitiro ekuvandudza kwavo kudzokorora kwemvura. Semuenzaniso, nekuwedzera vamwe polymers kana matacelids, iyo yekuchengetwa kwemvura yeHPMC inogona kuwedzerwazve. Uye zvakare, zvimwe zvigadzirwa zvichavandudza kunaka kwavo nekuwedzera anti-caking vamiririri, kugadzira HPMC kwakanyanya panguva yekushandisa.
9. Nzira dzekuyedza
Paunenge uchisarudza HPMC, dzimwe nzira dzekuyedza dzinogona kushandiswa kuongorora kuchengetwa kwemvura kwayo. Semuyenzaniso:
Mvura inobata bvunzo: Sarudza huwandu hwemvura iyo HPMC inogona kutora mune imwe nguva yenguva.
Mvura akabata bvunzo yekugona: Bvunza kugona kwekusagadzikana®HPMC kuchengetedza mvura panguva yekusanganisa nemamiriro ekuvaka ekuvaka.
Kutsunga kwekuvisa: viscosity zvakananga kunokanganisa hydration yayo. Kuchengeta kwemvura kwaro kunotongwa neViscosity. HPMC ine yakakwira viscosity kazhinji ine kuchengetwa kwemvura kuri nani.
Kana uchisarudza kodzeroHpc. Performance mukuchengetwa kwemvura kunosangana nezvinodiwa. Kunyanya mukuvakwa uye maindasitiri emuchina, iyo yekuchengetwa kwemvura yeHPMC haina kungoita chete nezvekuvaka, asi inogona zvakare kubata iyo yekupedzisira yechigadzirwa, saka inofanira kusarudzwa nekungwarira kwakanyanya.
