1. Chii chinonzi hydroxypropyl methylcellulose?
Hydroxypropyl methylcellulose (HPMC)i-non-ionic cellulose ether isina chepfu uye isingakuvadzi, inoshandiswa zvakanyanya mukuvaka, chikafu, mishonga, zvizoro nedzimwe nzvimbo. Ine mabasa ekukora, kuchengetedza mvura, kugadzira firimu, kubatana, kukwiza mafuta uye kumisa, uye inogona kunyungudika mumvura kugadzira mhinduro yakajeka kana inopenya.
2. Mashandisirwo akajairika uye kushandiswa kweHPMC
Munda wekuvaka
HPMC inowanzoshandiswa mukuvaka zvinhu zvakaita sedhaka resimende, upfu hweputty, namira yemataira, nezvimwewo.
Basa: Kuvandudza mashandiro ekuvaka, kuvandudza kuchengetedza mvura, kuwedzera nguva yekuvhura, uye kuvandudza mashandiro ekubatanidza.
Nzira yekushandisa:
Wedzera zvakananga kudhaka rakaoma rakasanganiswa, huwandu hunokurudzirwa i0.1% ~ 0.5% yehukuru hwesimende kana substrate;
Mushure mekukurunga zvizere, wedzera mvura wobva wasanganisa kuita slurry.
Indasitiri yezvekudya
HPMC inogona kushandiswa sechinhu chinosimbisa, chinosimbisa uye chinosanganisa makemikari, uye inowanikwa muzvikafu zvakaita se ice cream, jelly, chingwa, nezvimwewo.
Basa: Kuvandudza kuravira, kudzikamisa hurongwa, uye kudzivirira kupatsanurwa kweganda.
Mashandisirwo:
Nyungudutsa mumvura inotonhora, chiyero chinokurudzirwa chinogadziriswa pakati pe0.2% ne2% zvichienderana nerudzi rwechikafu;
Kupisa kana kusanganisa nemagetsi zvinogona kukurumidzisa kunyungudika.
Indasitiri yemishonga
HPMC inowanzoshandiswa mukugadzira mapiritsi emushonga, mapiritsi anoburitswa kwenguva refu kana kuti capsule shell:
Basa: kugadzirwa kwemafirimu, kunonoka kuburitswa kwemishonga, uye kudzivirira kushanda kwemishonga.
Mashandisirwo:
Gadzirira mushonga une huwandu hwe1% kusvika 5%;
Pfapfaidza zvakaenzana pamusoro pepiritsi kuti uite firimu rakatetepa.
Zvizoro
HPMCinoshandiswa semushonga wekuomesa, emulsion stabilizer kana firimu, inowanzoshandiswa mumasiki echiso, mafuta ekuzora, nezvimwewo.
Basa: Kuvandudza magadzirirwo uye kuwedzera kunzwa kwechigadzirwa.
Mashandisirwo:
Wedzera ku cosmetic matrix zvakaenzana uye sanganisa zvakaenzana;
Chipimo chinowanzova 0.1% kusvika 1%, chinogadziriswa zvichienderana nezvinodiwa nechigadzirwa.
3. Nzira yekunyungudutsa HPMC
Kunyungudika kweHPMC kunokanganiswa zvakanyanya nekupisa kwemvura:
Zviri nyore kunyungudika mumvura inotonhora uye zvinogona kugadzira mhinduro yakafanana;
Hainyungudike mumvura inopisa, asi inogona kupararira yoita colloid mushure mekutonhora.
Matanho chaiwo ekunyungudika:
Dururirai HPMC zvishoma nezvishoma mumvura, musadururira zvakananga kuti musabikire;
Shandisa muchina wekusanganisa kuti usanganise zvakaenzana;
Gadzirisa huwandu hwemvura inobuda mumhinduro sezvinodiwa.
4. Nzira dzekudzivirira pakushandisa HPMC
Kudzora mupimo: Muzviitiko zvakasiyana-siyana zvekushandiswa, mupimo wacho unokanganisa zvakananga mashandiro uye unofanirwa kuongororwa zvichienderana nezvinodiwa.
Mamiriro ekuchengetedza: Inofanira kuchengetwa munzvimbo inotonhorera, yakaoma, ine mhepo inofefetera kudzivirira hunyoro uye kupisa kwakanyanya.
Kudzivirirwa kwezvakatipoteredza: HPMC inogona kuora uye haisvibisi nharaunda, asi ichiri kuda kushandiswa nenzira yakajairika kudzivirira marara.
Kuongororwa kwekuenderana: Kana zvawedzerwa kune masisitimu akaomarara (akadai sezvizoro kana mishonga), kuenderana nezvimwe zvinhu kunofanira kuyedzwa.
5. Mabhenefiti eHPMC
Haina chepfu, ine hushamwari kune nharaunda, yakachengeteka zvakanyanya;
Kuchinja-chinja, kuchichinjika kune zvakasiyana-siyana zvinodiwa zvekushandisa;
Kugadzikana kwakanaka, kunogona kuchengetedza mashandiro kwenguva yakareba.
6. Matambudziko nemhinduro dzakajairika
Dambudziko rekubatana: Nyatsoteerera kuwedzera kwakapararira panguva yekushandisa uye kurungai zvizere panguva imwe chete.
Nguva refu yekunyungudika: Kugadzirira kushandisa mvura inopisa kana kusanganisa nekushandisa michina kunogona kushandiswa kukurumidzisa kunyungudika.
Kudzikira kwekushanda: Nyatsoteerera nzvimbo yekuchengetera zvinhu kuti usanyanya kunyorova kana kupisa.
Nekushandisa HPMC nesainzi uye nepfungwa dzakanaka, hunhu hwayo hune mabasa akawanda hunogona kushandiswa zvizere kupa mhinduro dzemhando yepamusoro kumaindasitiri akasiyana-siyana.
