Viscosity ndiyo yakakosha parameter pakuita kwehydroxypropyl methylcellulose (HPMC). HPMC inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwemvura inonyungudika polymer, isiri-ionic, isiri-chepfu uye zvimwe zvinhu. Iyo ine yakanakisa firimu-inogadzira, yakakora uye inonamira zvivakwa, zvichiita kuti ive sarudzo inokwezva kune akasiyana maapplication.
Viscosity chiyero chekuramba kwemvura mukati kuti ibude. Nemamwe mashoko, inoyera ukobvu kana kutetepa kwemvura. Viscosity yakakosha parameter yeHPMC performance sezvo ichikanganisa kuyerera kwemhinduro. Iyo yakakwirira viscosity, iyo yakakura mhinduro uye inononoka inoyerera. Viscosity ine tarisiro yakananga pakushandisa uye kushanda kweHPMC.
Imwe yeakakosha maapplication eHPMC yakaita seyakakora. Nekuda kwehuremu hwayo hwemamorekuru uye hydrogen bonding properties, HPMC inoumba gel gobvu-rakafanana nechinhu kana chanyungudutswa mumvura. Iyo viscosity yeHPMC yakakosha pakuona kuenderana kwemhinduro. Iyo yakakwirira iyo viscosity, iyo yakakura mhinduro. Ichi chivakwa chinoita kuti ive yakanakira kukora zvikumbiro muzvigadzirwa zvakaita sependi, machira uye zvinonamira.
Chimwe chakakosha kushandiswa kweHPMC mishonga yemishonga. Inoshandiswa sechinhu chinobatsira mumhando dzakasiyana-siyana dzakadai semapiritsi, capsules uye mafuta. Iyo viscosity yeHPMC inoita basa rakakosha mukugadzirwa kwezvinhu izvi. Inobata kuyerera, kuwirirana uye kugadzikana kwekugadzirisa. Viscosity yakakodzera inodiwa kuti ive nechokwadi chekuti chigadzirwa chiri nyore kubata uye chinogona kupihwa dosed nemazvo. HPMC ine yakaderera viscosity kana yakanyungudika mumvura, zvichiita kuti ive yakanaka yekugadzirira mhinduro uye kumiswa.
Viscosity inoitawo basa rakakosha mukuita kweHPMC kuindasitiri yekuvaka. Iyo inoshandiswa zvakanyanya seyakakora uye bhainda mune simende-yakavakirwa zvinhu zvakaita sedhaka uye grout. Iyo viscosity yeHPMC inotaridza iyo processability uye nyore kwekushandisa kwezvinhu izvi. Viscosity yakakodzera inodiwa kuve nechokwadi chekuti zvinhu zvinogona kushandiswa nyore uye kupararira zvakaenzana. HPMC ine yakanakisa viscosity kugadzikana inoita kuti ive yakanakira kuvaka zvikumbiro.
Viscosity inokanganisawo hupenyu hwesherufu hweHPMC zvigadzirwa. Iyo viscosity yeHPMC inogona kuwedzera kana kuderera nekuda kwezvinhu zvakati wandei senge tembiricha, pH uye kutarisisa. Shanduko mune viscosity inogona kukanganisa zvigadzirwa zvechigadzirwa uye mashandiro, zvichikonzera kukanganisa kwechigadzirwa kana kuderera kwekuita. Naizvozvo, iyo viscosity yeHPMC-yakavakirwa zvigadzirwa inofanirwa kuchengetedzwa kuti ive nechokwadi chekugadzikana uye kushanda kwayo.
Viscosity ndiyo yakakosha parameter yekushanda kwehydroxypropylmethylcellulose (HPMC). Inokanganisa maitiro ekuyerera, ukobvu uye kushanda kweHPMC zvigadzirwa. Iyo viscosity yakakodzera inodiwa kuti ive nechokwadi chekuti chigadzirwa chiri nyore kushandisa uye mita, ine kugadzikana kwakanaka uye inoshanda nekufamba kwenguva. HPMC ine yakanakisa viscosity kugadzikana, iyo inoita kuti ive sarudzo inokwezva kune dzakasiyana siyana mashandisirwo mumaindasitiri akadai semishonga, kuvaka uye kutarisirwa wega.
