Hydroxypropylmethylcellulose (HPMC) inotorwa selulosi inowanzoshandiswa mumaindasitiri akasiyana nhasi. Inonyanya kushandiswa se thickener, adhesive uye stabilizer mune chikafu, mishonga uye cosmetic maindasitiri. Inosarudzwa pane dzimwe sarudzo nekuti iri nyore kushandisa, yakachengeteka uye isina chepfu. Nekudaro, chinhu chakakosha chekemikari iyi ndeye madota ayo.
Iyo madota emukati eHPMC chinhu chakakosha pakuona kunaka kwayo uye kuchena. Madota emukati anoreva iyo mineral uye inorganic zvinhu zviripo mune inotorwa selulosi. Aya maminerari anogona kuve ari mudiki kana hombe, zvichienderana nekwakabva uye mhando yeHPMC.
Zvemukati zvemadota zvinogona kutsanangurwa nekupisa huwandu hwakati hweHPMC pakupisa kwakanyanya kubvisa zvese organic zvinhu, zvichisiya chete inorganic zvakasara. Madota eHPMC anofanirwa kunge ari mukati mechikamu chinogamuchirika kudzivirira kusvibiswa uye kuve nechokwadi chekuti chimiro chayo chemuviri nemakemikari hachikanganisike.
Iyo inogamuchirwa madota emukati eHPMC anosiyana zvichienderana neindasitiri iyo inoshandiswa. Semuyenzaniso, indasitiri yechikafu ine mirau yakasimba pahuwandu hwemadota anotenderwa muHPMC. Madota emukati wegiredhi rekudya HPMC anofanira kunge ari pasi pe1%. Kushandiswa kwevanhu kwechinhu chipi nechipi chiri pamusoro pemuganhu uyu kunoisa hutano hwehutano. Naizvozvo, zvakakosha kuve nechokwadi chekuti chikafu-giredhi HPMC ine chaiyo madota emukati.
Saizvozvo, iyo indasitiri yemishonga ine mirau pane madota emukati eHPMC. Madota anobvumirwa anofanira kunge ari pasi pe5%. Chero HPMC inoshandiswa muindastiri inofanirwa kuve yekuchena kwayo kana mhando kudzivirira kusvibiswa.
Vagadziri vezvizoro vanodawo yemhando yepamusoro HPMC ine yakakodzera madota. Izvi zvinodaro nekuti chero akawandisa madota ari muHPMC anogona kuita pamwe nezvimwe zvinongedzo muzvizoro, zvichikonzera kukanganisa kwemuviri uye kemikari paganda.
Madota emukati eHPMC anofanirwa kunge ari mukati memiganho inogamuchirwa kune yega yega indasitiri yainoshandiswa mairi. Nekudaro, hazvina kukwana kutonga kunaka kweHPMC chete nemadota. Zvimwe zvinhu zvakaita seviscosity, pH uye hunyoro hwemukati zvakare hunoita basa rakakosha mukuona huwandu hwayo hwese.
HPMC ine madota chaiwo ane mabhenefiti akati wandei. Inovimbisa kuchena kwechigadzirwa uye kunaka, inoderedza njodzi yekusvibiswa uye inovandudza kuchengetedzwa kwechigadzirwa. Izvi zvinoita kuti zvive nyore kune vanogadzira kuti vasangane nemirairo yepamutemo kune yega yega indasitiri.
Iyo ash yemukati yehydroxypropyl methylcellulose chinhu chakakosha kuve nechokwadi chemhando yechigadzirwa uye kuchengetedzeka. Kuve nechokwadi chekuti HPMC ine chaiyo madota emukati kune yega yega indasitiri yekushandisa kwakakosha. Vagadziri vanofanirwawo kushandisa emhando yepamusoro HPMC yekuchena kwakakodzera uye kuona kuti vanosangana nemaindasitiri zviyero. Iine madota akakodzera, HPMC icharamba iri chinhu chakakosha mumaindasitiri akasiyana.
