Hydroxypruppyl methyl cellulose
Kugadzirira Nguva Yekuedzwa
Nguva yekugara yekongiri inonyanya kuve neyakaenderana nenguva yekudzora, saka nguva yekusagadzikana nekuda kweiyo mongororo yemvura, sangano reSand Ratio Nguva, iyo yemvura-yemvura inowanzoitika uye simende-jecha chiyero chetambo chinoda kugadziriswa.
HPMC ndeye macromolecule mutsara, ne hydroxyl boka pane iro basa reboka, iro rinogona kuumba hydrogen zvisungo nemamolekyudhi emvura uye kuwedzera zvikwangwani zvemvura yekusanganisa. HPMC marefu marefu emachira anokwezva, saka HPMC mamorekuru akanganisa pamwe chete kuti agadzire network chimiro, iyo simende, kusanganisa mvura yakaputirwa. Nekuti HPMC inoumba seti network yakafanana neyekuonda firimu uye kuputira kweiyo simende, ichaita zvinobudirira kusevha kwemanyoro mumotokari, kudzora kana kudzora mwero wehystem.
Mvura inoteedzera bvunzo
Iyo-inobuda-bhuroka phenomenon yakafanana neyakajairwa nekongiri, inotungamira kuwanda kwemvura yekuputika, uye kupaza nzvimbo yekutanga, uye simba rezvemusoro wetsiva rakanyanya kushaya simba. Kubva muyedzo, inogona kuoneka kuti kana iyo yekusanganisa huwandu iri pamusoro 0.5%, hapana mvura yekudzora phenomenon. Izvi zvinodaro nekuti HPMC yakavhenganiswa, HPMC ine mafirimu ekuumbwa uye nedanho reiyo hydroxyl paMarromolecules, kuitira kuti simende iri muumbi yemvura, kuve nechokwadi chekutakura chimiro chemuviri. Mushure mekuwedzera HPMC muMoter zvakare, akawanda akazvimirira matinji emabhuru anoumbwa. Aya mabhuru anogoverwa zvakanyanyisa mudhaka uye anotadzisa kuiswa kweanounganidzwa. HPMC yekuita kwehunyanzvi yeiyo coment based ine simba rakakura, kazhinji dzinoshandiswa kugadzirira sedare rakaoma, polymer doler uye kuti ine kuchengetedzwa kwemvura, kuitira kuti ive nekuchengetwa kwemvura, kupurikana.
