Hydroxypropyl methylcellulose (HPMC) ipolymer inotorwa muselulosi uye inowanzoshandiswa mumaindasitiri akasiyana siyana, kusanganisira mishonga, zvizorwa, uye chikafu.Iyo polymer inonyungudika nemvura inogona kunyoroveswa nyore nyore kuti iite viscous solution.
1. Kunzwisisa HPMC:
Usati wakurukura nezve hydration maitiro, zvakakosha kuti unzwisise zvimiro zveHPMC.HPMC inonzi semi-synthetic polymer iri hydrophilic, zvichireva kuti ine hukama hwakasimba hwemvura.Iyo inoumba yakajeka, inoshanduka, uye yakagadzikana gels kana iine hydrated, ichiita kuti ive yakakodzera kune zvakasiyana-siyana zvekushandisa.
2. Hydration process:
Iyo hydration yeHPMC inosanganisira kuparadzira hupfu hwepolymer mumvura uye kuibvumira kuzvimba kuti iite viscous solution kana gel.Heino nhanho-ne-nhanho gwara kune hydrating HPMC:
Sarudza Giredhi Rakanaka:
HPMC inowanikwa mumagiredhi akasiyana-siyana ane akasiyana mamolecular uremu uye viscosity mamakisi.Kusarudzwa kwegiredhi rakakodzera kunoenderana neinoda viscosity yekupedzisira mhinduro kana gel.Akakwira mamorekuru uremu mamakisi anowanzo konzera yakakwira viscosity mhinduro.
Gadzirira Mvura:
Shandisa yakacheneswa kana deionized mvura ye hydrating HPMC kuona kusavapo kwetsvina iyo inogona kukanganisa zvimiro zvemhinduro.Kupisa kwemvura kunogonawo kukanganisa hydration process.Kazhinji, kushandisa tembiricha yekamuri mvura yakakwana, asi kupisa mvura zvishoma kunogona kukurumidza kuita hydration.
Kupararira:
Paridza zvishoma nezvishoma HPMC poda mumvura uchikurudzira nguva dzose kudzivirira kuumbwa kwezviputi.Izvo zvakakosha kuti uwedzere iyo polymer zvishoma nezvishoma kuve nechokwadi kupararira kwakafanana uye kudzivirira agglomeration.
Hydration:
Ramba uchikurudzira musanganiswa kusvikira hupfu hweHPMC yose hwapararira mumvura.Bvumira musanganiswa kuti umire kwenguva yakakwana kuti ubvumire zvikamu zvepolymer kuzvimba uye hydrate zvizere.Nguva ye hydration inogona kusiyana zvichienderana nezvinhu zvakaita setembiricha, polymer giredhi, uye viscosity yaunoda.
Kusanganiswa uye Homogenization:
Mushure meiyo hydration nguva, sanganisa mhinduro yacho zvakakwana kuti uve nechokwadi chekufanana.Zvichienderana nekushandiswa, kuwedzera kusanganisa kana homogenization kungave kuri madikanwa kuti uwane iyo inodiwa kuenderana uye kubvisa chero mapundu asara.
Kugadzirisa pH uye Additives (kana zvichidikanwa):
Zvichienderana nechishandiso chaicho, ungangoda kugadzirisa pH yemhinduro uchishandisa asidhi kana mabhesi.Pamusoro pezvo, zvimwe zvekuwedzera senge mapreservatives, plasticizers, kana thickeners zvinogona kuiswa mumhinduro panguva ino kusimudzira kuita kwayo kana kugadzikana.
Sefa (kana zvichidikanwa):
Mune zvimwe zviitiko, kunyanya mumishonga yemishonga kana yezvizoro, kusefa iyo hydrated solution ingave yakakosha kubvisa chero zvidimbu zvisina kunyungudutswa kana tsvina, zvichikonzera chigadzirwa chakajeka uye chakafanana.
3. Zvishandiso zveHydrated HPMC:
Hydrated HPMC inowana zvikumbiro mumaindasitiri akasiyana siyana:
- Indasitiri yeMishonga: Mukugadzirwa kwemishonga, hydrated HPMC inoshandiswa seyakakora mumiriri, binder, uye firimu-inogadzira mumiriri mune mahwendefa ekuputira.
- Cosmetic Indasitiri: HPMC inowanzo shandiswa muzvigadzirwa zvekuzora zvakaita semafuta, lotions, uye gels seyakakora, stabilizer, uye firimu-inogadzira mumiriri.
- Indasitiri yeChikafu: Muindasitiri yechikafu, hydrated HPMC inoshandiswa seyakakora, emulsifier, uye inodzikamisa muzvigadzirwa zvakaita sesosi, madhirezi, uye zvigadzirwa zvemukaka.
-Indasitiri yeKuvaka: HPMC inoshandiswa mukuvaka zvinhu senge madhaka, grouts, uye mataira anonamira kuvandudza kushanda, kuchengetedza mvura, uye kunamatira.
4. Mhedziso:
Hydroxypropyl methylcellulose (HPMC) i polymer inoshanda zvakasiyana-siyana iyo inogona kunyoroveswa nyore nyore kuti igadzire viscous mhinduro kana gels.Iyo hydration process inosanganisira kuparadzira HPMC poda mumvura, ichibvumira kuzvimba, uye kusanganisa kuti iwane yunifomu kusagadzikana.Hydrated HPMC inowana zvikumbiro mumaindasitiri akasiyana siyana, anosanganisira emishonga, zvekuzora, chikafu, uye kuvaka.Kunzwisisa iyo hydration maitiro uye zvimiro zveHPMC zvakakosha pakugadzirisa mashandiro ayo mumashandisirwo akasiyana.
