HPMC kana hydroxyprusyl methylcellose chinhu chose chinhu chinoshandiswa mune dzakasiyana-siyana maindasitiri kusanganisira mishonga, cosmetics uye chikafu. Iyo inoshandiswa zvakanyanya sedhizimusi uye emulsifier, uye viscosity yayo inoshanduka zvichienderana nekudziya kwarwoneka. Munyaya ino, isu tichatarisa nezvehukama pakati peviscosity uye tembiricha muHPMC.
Viscosity inotsanangurwa sechiyero chekupokana kwemvura kuyerera. HPMC ndeye seemi-solids inopfuura iyo yekuyera kuyerwa zvinoenderana nezvakasiyana zvinhu, kusanganisira tembiricha. Kuti unzwisise hukama pakati pevisikopo uye tembiricha muHPMC, takatanga kuziva kuti chinhu chinoumbwa sei uye icho chakagadzirwa.
HPMC inotorwa kubva kuCellulose, chisikwa chinoitika polymer mune zvirimwa. Kuti uburitse HPMC, cellulose inofanirwa kuve nemakemikari kugadziridzwa neProfylexo oxide uye methyl chloride. Uku kugadziridzwa kunoguma nekuumbwa kwehydroxyprupyl uye methyl ether mapoka muCellulose Chain. Mhedzisiro yacho inyomarara-solid isinganyungudika mumvura uye organic sol soles uye inoshandiswa mune dzakasiyana-siyana dzekushandisa, kusanganisira kuunganidza mahwendefa uye sekureva kwemazwi ekudya, pakati pevamwe.
Iyo viscosity yeHPMC inoenderana nekushambadzira kweiyo chinhu uye tembiricha iyo iyo yafumurwa. Kazhinji, viscosity yeHPMC inoderera nekuwedzera kusungwa. Izvi zvinoreva kuti zvakakwirira zvepamusoro zveHPMC mhedzisiro mune yakaderera viscookiti uye zvinopesana.
Nekudaro, hukama hwakafanana pakati peviscosity uye tembiricha zvakanyanya kuomarara. Sezvambotaurwa, viscosity yeHPMC inowedzera nekudzora tembiricha. Izvi zvinoreva kuti iyo HPMC yakaiswa kuderera tembiricha, kugona kwayo kuyerera kuderera uye kunova kuwedzera viscous. Saizvozvo, hpmc kana hpmc yakaiswa mukudziya kwakanyanya, kugona kwayo kuyerera kunowedzera uye viscoity yayo inoderera.
Pane zvinhu zvakasiyana siyana zvinokanganisa hukama pakati pekudziya uye viscosity muHPMC. Semuenzaniso, mamwe maitiro anogara ari mumvura anogona kukanganisa viscosity, sezvinoita ph yemvura. Kazhinji, zvakadaro, kune hukama hwakafanana pakati pevisikopo uye tembiricha muHPMC nekuda kwekushisa kwekushisa kwehydrogen nekuwirirana kweiyo cellulose chain muHPMC.
Hpmc painenge yakaiswa kuderera tembiricha, maCellulose maketani anova akaomarara, ayo anotungamira kuwanda hydrogen kusungwa. Aya ma hydrogen zvisungo zvinokonzeresa kuramba kuyerera, nekudaro kuri kuwedzera zvavakaita. Zvekare, maHpmc akaiswa munzvimbo dzakakwirira dzekupisa, maketani cellulose akawedzera kuchinjika, izvo zvakakonzera kushoma kwehydrogen zvisungo. Izvi zvinoderedza kuramba kwezvinhu kuyerera, zvichikonzerwa neyakaderera viscosity.
Izvo zvakakosha kucherechedza kuti nepo pane kazhinji hukama hwehukama pakati pevisikopo uye tembiricha yeHPMC, izvi hazvisi nguva dzose nyaya yemhando dzese dzeHPMC. Ukama chaihwo pakati peviscosity uye tembiricha zvinogona kusiyana zvichienderana nemaitiro ekugadzira uye iyo chaiyo giredhi reHPMC yakashandiswa.
HPMC ndeye multifauntily chinhu chinoshandiswa zvakanyanya mune dzakasiyana-siyana maindasitiri ekurongedza kwayo uye anofungidzira zvivakwa. Iyo viscosity yeHPMC inoenderana nezvikamu zvinoverengeka, kusanganisira kusanganisa kwechinhu uye tembiricha iyo iyo iyo yafumurwa. Muzhinji, iyo viscosity yeHPMC inoenderana neyakaenzana nekushisa, zvinoreva kuti sezvo tembiricha inoderera, iyo viscosity inowedzera. Izvi zvinokonzerwa nemhedzisiro yekushisa pane hydrogen maruva uye molecular yekudyidzana kweiyo cellulose chain mukati hpmc.
