HPMC, inozivikanwawo se hydroxyprupyl methylcellose, inzvimbo yekuve yemhuri yemhuri yevaneta. Iyo inotorwa kubva ku cellulose, iyo yepamhepo polymer inowanikwa mumasango masero emadziro. HPMC inoshandiswa zvakanyanya mune yekuvaka indasitiri nekuda kwenzvimbo yayo yakawanda yemarudzi.
HPMC inowanzoshandiswa seyakavharwa, binder, yefirimu yaimbova uye yemvura-yekuchengetedza mumiririri mukuvakira zvinhu zvakadai seyakagadzirwa-based zvigadzirwa, matanda emagetsi, mapuranga uye graster. Chemakero chemuchemumoyo chinozvitendera kuti itore mvura uye gadzira chinhu cheGel-seichi chinovandudza basa rekushanda, kudenha uye sag kuramba zvekuvaka.
Heano mamwe mimwe nzvimbo yakakosha uye zvikumbiro zveHPMC mune yekuvaka indasitiri:
Kudzokorora kwemvura: HPMC inobata uye inochengetedza mvura, kudzivirira masendimita-yakavakirwa zvinhu kubva mukuomesa kunze. Izvi zvinobatsira kuderedza kupaza, zvinovandudza hydration uye nekuwedzera simba rose uye kusimba kwezvigadzirwa zvekuvaka.
Kuvandudzwa Kurovedza: HPMC zviito senge rheology modifier, kupa zviri nani kuita uye nyore kushanda kwezvinhu zvekuvaka. Iyo inosimudzira kuwanda uye kutsvedza kuramba kwemauto uye plasters, kuita kuti vakurise kubata uye kushandisa.
Adhisheni uye kubatana: HPMC inovandudza kudiwa pakati pezvivakwa zvakasiyana zvekuvaka. Inowedzera kusungwa kwesimba kwemiwile inonamira, plasters uye inovhara zvakanyatsonamatira kune simbisa yakadai sekongiri, huni uye mataira.
Sag Kudzvinyirira: HPMC inoderedza SAG kana kudonha kwezvinhu zvevatambi zvakaita se tile inonamira kana primer panguva yekushandisa. Izvi zvinobatsira kuchengetedza kwakashuwira ukobvu uye kudzivirira warping kana kudonhedza.
Film formation: Kana HPMC Dries, inoumba yakaonda, inoshanduka, yakajeka firimu. Iyi firimu inogona kupa zviri nani kupokana kwemvura, kuramba uye kudzivirirwa kwemamiriro ekunze kwezvinhu zvaishandiswa zvekuvaka.
