HydroxyPropyl methylcellose (HPMC) inzvimbo yezvinhu zvose zvinoshandiswa zvakanyanya mumasango akasiyana-siyana, kusanganisira mishonga yemishonga, cosmetics, chikafu, uye kuvaka. Kugona kwayo kuumba gels, mafirimu, uye mhinduro kunoita kuti ive yakakosha kune yakawanda application. Hydration yeHPMC idanho rakakosha mune dzakawanda maitiro, sezvazvinoita kuti polymer kuratidzira zvivakwa zvayo zvinobudirira.
1. Kunzwisisa HPMC:
HPMC ndeyekubva kune imwe cellulose uye iri yakanyorwa nekurapa cellulose ine procylone oxide uye methyl chloride. Iyo inoratidzirwa neyakawirwa nemvura-solubility uye kugona kuumba pachena, iyo yekuzvidzora jekeri. Dhigirii yehydroxypruppropyl uye nzira yekutsiva inokanganisa zvivakwa zvaro, kusanganisira solubility, viscossity, uye maitiro ehondo.
2. Kukosha kweHydration:
Hydration yakakosha kuvhura mashandiro eHPMC. HPMC yakaomeswa, inobata mvura uye inopinda mvura, inotungamira kuumbwa kwemhinduro yeViscous kana gel, zvichienderana nekumisikidza uye mamiriro. Iyi mamiriro okumusoro inogonesa HPMC kuti iite mabasa ayo akagadzirirwa, sekuremerwa, kurira, kuumbwa-firimu, uye kusimudzira zvinodhaka.
3. Nzira dze hydration:
Kune nzira dzinoverengeka dze hydating hpmc, zvichienderana nekunyorera uye zvinodikanwa mhedzisiro:
a. Kutonhora Kwemvura Kupararira:
Iyi nzira inosanganisira kuparadzira HPMC poda mumvura inotonhora ichimutsa zvinyoro nyoro.
Kutonhora kwemvura kupararira kunodiwa kuti udzivise kudzikisira uye kuve nechokwadi cheyakagadziriswa hydration.
Mushure mekupararira, mhinduro yacho inowanzobvumidzwa kuenderera mberi nekuenderera mberi nekukasira kukuru kwekuita viscosity yaunoda.
b. Kupararira kwemvura inopisa:
Nenzira iyi, HPMC poda inopararira mumvura inopisa, kazhinji pakupisa pamusoro 80 ° C.
Mvura inopisa inofambisa nekukurumidza hydration uye kupaza hpmc, zvichikonzera mhinduro yakajeka.
Kuchengeta kunofanirwa kutorwa kuti udzivise kuwandisa kupisa, izvo zvinogona kushatisa hpmc kana kukonzera kuumbwa kwehombodo.
c. Kusarerekera:
Zvimwe zvinoshandiswa zvinogona kusanganisira kusimbisa HPMC mhinduro neAlkaline vamiririri senge sodium hydroxide kana potasasium hydroxide.
Kusarerekera kunogadzirisa iyo pH yemhinduro, iyo inogona kupesvedzera viscosity uye magazini eHPMC.
d. Solvent kuchinjanisa:
HPMC inogona zvakare kuve yakavezwa ne solvent kuchinjanisa, uko kwakaparadzirwa mumvura-kusanzwisisika solen like itshanol kana methanol uye yakazoshandurwa nemvura.
Solvent kuchinjanisa kunogona kubatsira kuti application inoda chaizvo kudzora pamusoro pe hydration neiscosity.
e. Pre-hydration:
Pre-hydration inosanganisira kusanzwisisika HPMC mumvura kana solvent usati wabatanidza kuita mafambiro.
Iyi nzira inovimbisa kunyatso hydration uye inogona kubatsira kuwana kuwana mhedzisiro inoenderana, kunyanya mune yakaoma tsika.
4. Zvinhu zvinokanganisa hydration:
Zvinhu zvinoverengeka zvinopesvedzera hydration yeHPMC:
a. Saizi yeChipenga: Yakapfigira HPMC Powder Hydrates yakawanda pane coarse zvidimbu nekuda kwekuwedzera nzvimbo nzvimbo.
b. Kupisa
c. PH: iyo pH yeiyo hydaration yepakati inogona kukanganisa iyo Ionization mamiriro eHPMC uye nokudaro kwayo hydration kinetics uye rheological zvivakwa.
d. Kusanganisa: Kusanganisa kwakakodzera kana kusanganisa kwakakosha kune yunifomu hydration uye kupararira kweHPMC zvidimbu muSolvent.
e. Kusvinwa: Kuwedzeredza kweHPMC mune hydration yepakati svikiro dzeshuwa viscosity, Simba reGel, uye zvimwe zvivakwa zvemhedzisiro kana gel.
5. Zvishandiso:
Hprate hpmc inowana zvikumbiro zvakasiyana-siyana muindasitiri akasiyana-siyana:
a. Mishonga yemishonga yemishonga: Mujasi dzeshuwa, dzakadzorwa-dzisunungure matrices, mhinduro yeOphthalmic, uye kumiswa.
b. Zvigadzirwa zvekudya: Semizi, stabilizer, kana mafirimu-ekugadzira mumiririri mune sosi, zvipfeko, zvigadzirwa zveDoiry, uye confecicery.
c. Cosmetics: Mune kikes, lotions, gerle, uye zvimwe zvekugadzira zvevasikositi kushandurwa uye kwelussification.
d. Zvivakwa zvekuvaka: Mune zvigadzirwa-zvakavakirwa zvigadzirwa, tilesivives, uye zvinopa kuvandudza kudzorera, kudzokorora kwemvura, uye kudedera.
6. Hunhu Control:
Inoshanda hydration yeHPMC iri kutsoropodzwa kwechigadzirwa kuita uye kusawirirana. Hunhu hwekudzora matanho anogona kusanganisira:
a. Kukura kwehukuru Kuongororwa: Kuverengera kufanana kwehukuru hwekugovaniswa kwekuparadzira hydration kinetics.
b. Viscossity Kuyerwa
c. PH Monitoring: Kudzora iyo pH yeiyo hydration yepakati kuti isarudze hydration uye kudzivirira kusvibiswa.
d. Microscopic kuongororwa: Kuongorora kwekuona kweiyo hydrate samples pasi pe microscope kuti uongorore tangi nekuvimbika.
7. Mhedziso:
Hydration ndiyo nzira yakakosha mukubatanidza zvivakwa zveHPMC yezvikamu zvakasiyana siyana. Kunzwisisa nzira, zvinhu, uye mhando dzekudzora matanho zvakabatana ne hydration yakakosha pakugadzirisa chigadzirwa kuita uye kuve nechokwadi chekuenderana mukuumbwa. Nekunyengedza hydration yeHPMC, vaongorori uye vaongorori vanogona kuvhura zvizere zvizere zvakanyanya pane dzakasiyana siyana dzeindasitiri, kutyaira uye kugadzira kwechigadzirwa.
