HPMC (hydroxypropyl methylcellulose) inowanzoshandiswa isiri-ionic mvura-soluble polymer zvinhu, inoshandiswa zvakanyanya mumishonga, chikafu, kuvaka, kutarisira munhu uye mamwe minda.
1. Mamiriro ezvinhu
Iyo molecular chimiro cheHPMC ine yakakwira viscosity uye yakanaka rheological properties. Kune akawanda hydroxyl mapoka (-OH) pane ayo molecular cheni, anogona kuumba hydrogen zvisungo nemamorekuru emvura, kuitira kuti HPMC inogona kunyatsonyungudika mumvura kuti iite yakakwirira-viscosity colloidal mhinduro. Ichi chivakwa chinobvumira HPMC kunyatsoita gobvu mune fomula uye kuwedzera viscosity yechigadzirwa.
2. Kukora mhedzisiro
Iko kukora mhedzisiro yeHPMC inonyanya kuwanikwa kuburikidza nekudyidzana kwemamorekuru ayo maketani. Kana HPMC yanyungudutswa mumvura, maketani emamorekuru anosungirirana kuti agadzire network network, nekudaro ichiwedzera viscosity yemhinduro. Uku kukora mhedzisiro kunonyanya kuoneka mune zvigadzirwa zvemvura (sezvinwiwa, condiments) uye paste zvigadzirwa (semafuta ekuzora, ganda rekuchengetedza zvigadzirwa), izvo zvinogona kuvandudza kuravira uye kushandisa ruzivo rwechigadzirwa.
3. Kuvandudza kugadzikana
Nekuwedzera viscosity, HPMC inogona zvakare kuvandudza kugadzikana kwechigadzirwa. Mune akawanda kumiswa uye emulsions, kuwedzera viscosity kunogona kudzivirira sedimentation uye chikamu kupatsanurwa kwezvimedu zvakasimba, nekudaro kuchengetedza kufanana uye kutaridzika kwechigadzirwa. Semuenzaniso, mukuputira uye zvinonamira, kushandiswa kweHPMC kunogona kuvandudza rheological kugadzikana kwechigadzirwa uye kudzivirira kuitika kwesedimentation uye stratification.
4. Kudzora kusunungurwa kwekuita
Mundima yemishonga, HPMC inowanzo shandiswa sechikamu chemishonga inodzorwa kuburitsa masisitimu. Nekugadzirisa huremu uye mamorekuru eHPMC, kuburitswa uye kudzorwa kuburitswa kwemishonga kunogona kuwanikwa. Kuzvimba kweHPMC mumvura kunobvumira kuburitswa kwezvinodhaka mumuviri kudzorwa, nekudaro kuvandudza kushanda kwemishonga uye kuderedza mhedzisiro.
5. Wide kuchinjika
HPMC inogona kuramba ichichengetedza yakanaka yekukora zvivakwa munzvimbo dzine akasiyana pH kukosha uye ionic kusimba, izvo zvinoita kuti ishande mune akawanda akaoma maumbirwo. Kunyangwe iri acidic, alkaline kana isina kwayakarerekera system, HPMC inogona kupa yakagadzikana viscosity uye kuvandudza kushanda kwechigadzirwa.
6. Low concentration inobudirira
Kuenzaniswa nemamwe makobvu, HPMC inogona kunyatso kuwedzera viscosity pakadzika kudzika, kuderedza mutengo wekugadzira. Panguva imwecheteyo, iyi yakaderera yekumisikidza inogona kuderedza kukanganisa kune zvimwe zvinongedzo uye kuchengetedza kuchinjika uye kugadzikana kwefomula.
7. Kufurira zvinhu
The thickening effect yeHPMC inobatwa nezvinhu zvakawanda, kusanganisira rudzi rweHPMC (sezvakasiyana molecular weight, hydroxyl substitution), solution tembiricha, ion concentration, etc. Mumaapplication chaiwo, zvinofanirwa kuita gadziriso dzinoenderana zvinoenderana nezvinodiwa. yechigadzirwa kuti uwane yakanakisa viscosity mhedzisiro.
8. Mienzaniso yekushandisa
Muindasitiri yechikafu, HPMC inowanzo shandiswa kugadzira chikafu chakaderera-mafuta uye zvigadzirwa zvemukaka kubatsira kuvandudza kuravira uye kuenderana. Muindasitiri yekuvaka, HPMC inoshandiswa mune simende-yakavakirwa zvinhu kuvandudza kunamatira uye kushanda. Mumunda wemishonga, HPMC inoshandiswa zvakanyanya mumapiritsi, makapisi uye akasiyana mafomu emushonga kuvandudza fluidity uye kugadzikana.
Basa reHPMC mukuvandudza viscosity yechigadzirwa haigone kushomeka. Yayo yakasarudzika yemuviri uye makemikari zvimiro inoita kuti ive yakakosha thickener uye stabilizer mumaindasitiri mazhinji. Pakusarudza nekushandisa HPMC, zvinodikanwa kuita zviyero zvine musoro uye kushandisa zvinoenderana nehunhu uye zvinodiwa zvezvakagadzirwa zvigadzirwa kupa kutamba kwakazara kune zvakanakira.
