HPMC, inozivikanwawo sehydroxypropyl methyl cellulose, yakakosha nonionic cellulose yakasanganiswa ether. Zvinotora selulosi yechisikigo seyakagadzirwa, kuburikidza nekugadziriswa kwemakemikari, ine akawanda akasiyana emakemikari uye emuviri zvimiro, zvekuti yakashandiswa zvakanyanya mumishonga, cosmetics, chikafu uye mimwe minda.
Muchitarisiko, HPMC inowanzoratidzwa sechena kana chena-sefibrous kana granular powder. Iyi selulosi inobuda haingove neyakanakisa kunyungudika kwemvura uye inogona kunyungudika zviri nyore mumvura inotonhora uye inopisa, asi zvakare ine yakanakisa kuumbwa kwemafirimu uye kukora zvivakwa. Izvi zvinhu zvinoita kuti HPMC ive yakanakira thickener, stabilizer, emulsifier uye firimu rekugadzira mumiririri, anoita basa risingadzokerike mukugadzirwa kwezvakasiyana zvigadzirwa.
Mukuwedzera, HPMC yakaratidzawo kugadzikana kwakanaka. Inogona kuchengetedza kugadzikana kwechimiro chayo uye zvivakwa pasi pezvese tembiricha yepamusoro uye acidic mamiriro, ayo anopa mukana wekushandiswa kwayo munzvimbo dzakanyanyisa. Panguva imwecheteyo, saizi yayo yechikamu, carbonization tembiricha, density inooneka, chaiyo giravhiti, discoloration tembiricha uye tension yepasi uye zvimwe zvemuviri nemakemikari zvimiro zvakare zvinoenderana nezviyero zvekushandiswa kwemaindasitiri.
Mumunda wemishonga, HPMC inoitawo basa rakakosha. Nokuti iyo osmotic pressure yeaqueous solution yayo yakafanana neyemisodzi, haina kutsamwisa maziso, saka inowanzoshandiswa semafuta emishonga yemaziso, iyo inopa nyore kurapa zvirwere zvemaziso. Pamusoro pezvo, HPMC inogona zvakare kushandiswa semubatsiri (senge HPMC capsules) mumishonga yemumuromo kubatsira zvinodhaka kushanda zvirinani.
Muindasitiri yezvizorwa, HPMC inoshandiswa zvakanyanya mukukora uye kunyorovesa zvivakwa. Inogona kubatsira kudzora magadzirirwo uye kuenderana kwezvizoro uye kugadzirisa kushandiswa kwezvigadzirwa. Panguva imwecheteyo, hunhu hwayo hwekunyorovesa hunobatsirawo kuchengetedza hunyoro hwezvizoro, zvichiita kuti zvigadzirwa zvigare uye zvinobudirira.
Pamusoro penzvimbo dzekushandisa dziri pamusoro, HPMC inoitawo basa rakakosha muindasitiri yechikafu. Inogona kushandiswa seyakagadzika uye thickener yechikafu kuvandudza kuravira uye kuumbwa kwechikafu. Panguva imwecheteyo, nekuda kwenzvimbo yayo yechisikigo uye yakanaka biocompatibility, kushandiswa kweHPMC muchikafu kunopindirana zvakare nevanhu vemazuva ano kutsvaga hutano, kuchengetedzwa uye kuchengetedza kwezvakatipoteredza.
Muchidimbu, HPMC, seyakakosha cellulose derivative, ine huwandu hwakasiyana hwekushandisa munzvimbo dzakasiyana siyana. Hunhu hwayo hwakasiyana uye kuita kwakanakisa kunoita kuti ive chikamu chakakosha chezvakawanda zvigadzirwa zvemaindasitiri. Nekufambira mberi kwesainzi uye tekinoroji uye nekuvandudzwa kwezvinodiwa nevanhu zvehupenyu hwehupenyu, zvinotendwa kuti nzvimbo yekushandisa yeHPMC icharamba ichikura, ichiunza kurerukirwa uye kunyaradza kuhupenyu hwevanhu.
