Basa guru reHPMC mudhaka rakasanganiswa nemvura rine zvinhu zvitatu zvinotevera:
1. HPMC ine kugona kwakanaka kwekuchengetedza mvura.
2. Simba reHPMC pakuenderana uye thixotropy yedhaka rakasanganiswa nemvura.
3. Kudyidzana pakati peHPMC nesimende.
Kuchengetwa kwemvura ibasa rakakosha reHPMC, uye ibasa iro vagadziri vemadhaka akawanda anosanganisa mvura vanocherechedza.
Kuchengetwa kwemvura kweHPMC kunoenderana nekuwanda kwemvura muchikamu chepasi, kuumbwa kwechinhu chiri muhari, ukobvu hwechinhu chiri muhari, kudiwa kwemvura muhari, uye nguva yekuiswa kwechinhu chiri muhari.
HPMC - kuchengetedza mvura
Kana tembiricha yeHPMC yegel yakakwira, kuchengetedza mvura kuri nani.
Zvinhu zvinokanganisa kuchengetwa kwemvura kwedhaka rakasanganiswa nemvura ndekunaka kweHPMC, huwandu hwekuwedzera, kupfava kwezvikamu uye tembiricha yekushandisa.
Kusviba chinhu chakakosha pakushanda kweHPMC. Pachigadzirwa chimwe chete, mhedzisiro yekusviba inoyerwa nenzira dzakasiyana inosiyana zvikuru, uye dzimwe dzinotowedzera musiyano kaviri. Saka, pakuenzanisa kusviba, zvinofanirwa kuitwa pakati penzira dzakafanana dzekuyedza, kusanganisira tembiricha, spindle, nezvimwewo. Kazhinji, kusviba kwakakwira, ndiko kuri nani kuchengetedza mvura.
Zvisinei, kana viscosity yakakwira uye huremu hwemamorekuru hweHPMC hwakakura, kudzikira kwekunyungudika kwayo kuchaita kuti simba remota rive rakashata uye mashandiro ekuvaka. Viscosity yakakwira, zvinoita kuti mhedzisiro yekukora kwemota ive pachena, asi kwete zvakaenzana. Viscosity yakakwira, matope akanyorova anonamira zvakanyanya, izvo zvinoratidza kunamira kune scraper panguva yekuvaka uye kunamira zvakanyanya kune substrate. Zvisinei, HPMC haina simba rakawanda pakuvandudza simba remaumbirwo emota yakanyorova pachayo, zvichiratidza kuti mashandiro ekudzivirira kudzika haasi pachena. Kusiyana neizvi, mamwe HPMC akagadziriswa ane viscosity yepakati nepasi akanakisa mukuvandudza simba remaumbirwo emota yakanyorova.
Kupfava kweHPMC kunewo simba pakuchengetedza mvura. Kazhinji, kune HPMC ine viscosity yakafanana asi kupfava kwakasiyana, HPMC yakapfava, zvinoita kuti kuchengetedza mvura kuve nani kana yawedzerwa huwandu hwakafanana.
