HPMC, inozivikanwa zvakare seHydroxyprupyl methylcellose, inonyanya kushanda inoshandiswa zvakanyanya muindasitiri yekuvaka, kunyanya mugadziri yemadziro putty. Wall
Vavaki vazhinji vakave nematambudziko nekupunzika munguva yakapfuura. SAG inoitika kana putty ichitanga kutsvedza kubva kumadziro nekuda kwehuremu hwayo. Izvi zvinoguma zvaitika mukupedzisira uye kusazvibata kwekupedzisira kunotora nguva yakawanda uye kushanda nesimba kugadzirisa. Nekudaro, vavaki vakawana mhinduro nekuwedzera hpmc kumadziro putty, iyo inobatsira kuvandudza kudzikisira kweSAG uye huwandu hwechigadzirwa chekupedzisira.
Pane zvikonzero zvakati wandei nei Hpmc iri yakadaro inoshanda. Kutanga, zvinoita sedhizimikira, zvinoreva kuti zvinobatsira kuwedzera vhiza yezvinhu zvakatemwa. Uku kuwedzerwa viscosity kunoita kuti zviome kune iyo zvinyorwa kuti zvidzime kubva pamadziro uye unofambisa zviri nani kushamisika kune nzvimbo. Iyo Putty yakakurudzirwa viscosity inogonesa zvakare kuzadza microcracks uye madiki madiki mumadziro, kupa zvakapusa, zvakanyanya kunyange pamusoro. Iyi ficha inobatsira zvakare kuderedza huwandu hwekutyisa hunodiwa kuti uvhara nzvimbo yakapihwa nzvimbo, zvichikonzera mhinduro inowedzera mutengo.
Kechipiri, HPMC inoita basa rakakosha mukudzora kumhanya kwekuomesa kwemadziro putty. Iko kukurumidza kuomesa kunokanganisa zvakananga kudzikisira kweiyo putty, uye putty inononoka kudzvinyirira inowanzogadzikana uye isiri nyore kuSAG. HPMC inobatsira kudzora mwero wekusungirirwa kwemvura muchinyorwa chekutakura, izvo zvinokanganisa nguva yayo yekuomesa. Urongwa uhwu hunoguma mune hwakagadzikana uye hunowanzoitika hunomesa hunomutevera, kuderedza mukana wekutsvagira.
HPMC inogona zvakare kushandiswa kuvandudza kudedera pakati peWall putty uye substrate. ADHesion inoreva iyo degree kune iyo denty zvinyorwa zvinonamatira kumusoro iyo inoiswa. HPMC inogona kuvandudza zvakanyanya kuderedza nekuti inopa firimu rekudzivirira pamusoro, iyo inovandudza kuderedza kwekutyisa kune iyo subty.
Mukuwedzera, HPMC inogona zvakare kubatsira kuchengetedza kunyorova muWall putty zvinhu. Kunyangwe mvura ndiyo yakakosha yepakati yekugadzirisa uye kusimbisa, iri zvakare chikonzero chikuru chekupaza uye kusekerera kwezvinhu zvinobuda nekukurumidza. HPMC inobatsira kuchengetedza kunyorova mune iyo putty zvinyorwa kwenguva yakareba, ichibvumira iyo putty kuti igadzirise zvakanyanya uye yakaoma isina kuoma.
Kupedzisa, HPMC chinhu chakakosha uye chinoshanda mumadziro putty, chinoita basa rakakosha mukuwedzera nzvimbo yekunyepedzera yemadziro. Nekunetseka kwayo, kuomesa rate control, kuomesa kudzoreredza uye kurwadziswa kwemvura, HPMC inopa vavaki ndiyo inogadzirisa matambudziko eSag uye inovandudza huwandu hwechigadzirwa chekupedzisira. Iko mukana hakusi kungova mumashure, uye zvakare mukupedza, asiwo mune mutengo-kugona kwemhinduro. Naizvozvo, zvakafanira kuziva uye kusimbisa basa risingaperi reHpmc mune yekuvaka indasitiri.
