1. Chii chinonzi hydroxypruppropyl methylcellose?
Hydroxyprupyl methylcellose (HPMC)Isiri-ine chepfu uye isina kukuvadza isiri-inokanganisa cellulose ether, inoshandiswa zvakanyanya muzvivakwa zvekuvaka, chikafu, mushonga, cosmetics nedzimwe minda. Iyo ine mashandiro ekuremerwa, mvura yekuchengetwa kwemvura, kuumbwa kwefirimu, kusungirirwa, kuumbwa uye kumiswa, uye kunogona kunyungudika mumvura kuti ugadzire fungcous fancous mhinduro.
2. Zvakawanda zvinoshandiswa uye kushandiswa kweHPMC
Munda wekuvaka
HPMC inowanzo shandiswa pakuvaka yakadai seyakafa motsi, putty poda, tile inonamira, etc.:
Basa: Kuita kwekuvaka kwekuvaka, kuvandudza kuchengetedzwa kwemvura, kunatsiridza nguva yakavhurika, uye kuvandudza kuita kwekubatanidza.
Nzira yekushandisa:
Wedzera zvakananga kune yakaoma-yakavhenganiswa motsi, iyo yakakurudzirwa huwandu ndeye 0,1% ~ 0.5% yehuwandu hwesimbe kana substrate;
Mushure mekusimudzira zvizere, wedzera mvura uye kumutsa kuita slurry.
Indasitiri yechikafu
HPMC inogona kushandiswa sedhizimusi, stabilizer uye emulsifieri, uye inowanzo kuwanikwa mune zvekudya senge ice cream, jelly, chingwa, nezvimwe .:
Basa: Kuvandudza kuravira, kusimbisa hurongwa, uye kudzivirira kuoma.
Kushandiswa:
Nyungudika mumvura inotonhora, iyo yakakurudzirwa dosage inogadziridzwa pakati pe2,2% uye 2% zvichienderana nerudzi rwechikafu;
Kupisa kana kuita kwemakaniki kunogona kukurumidza kupaza.
Indasitiri yeMishonga
HPMC inowanzo shandiswa mudhisheni inodhonzwa inovhara, inotsigira-kubhururuka piritsi matrix kana capsule shell:
Basa: Firimu kugadzirwa, kunonoka kusunungurwa kwezvinodhaka, uye kuchengetedzwa kwezviitiko zvinodhaka.
Kushandiswa:
Gadzirirai mune mhinduro nejiseni ye1% kusvika ku5%;
Spray zvakanyanyisa pamusoro pehomwe yekugadzira firimu rakatetepa.
Cosmetics
Hpcinoshandiswa seyekukamisa, emulsion stabilizer kana firimu-inogadzira mumiririri, inowanzoshandiswa mune yechiso masks, lotions, nezvimwe.
Basa: Kuvandudza kugadzirwa uye kusimudzira kunzwa kwechigadzirwa.
Kushandiswa:
Wedzera kune cosmetic matrix muchikamu uye kumutsa zvakanyanyisa;
Iyo Dosage inowanzo 0.1% kusvika 1%, yakagadziriswa zvinoenderana nezvinodiwa zvigadzirwa.
3. HPMC dissolution nzira
Iyo solubility yeHPMC inokanganiswa zvikuru nekupisa kwemvura:
Zviri nyore kunyungudika mumvura inotonhora uye inogona kuumba yunifomu mhinduro;
Iko kusanzwisisika mumvura inopisa, asi inogona kuparadzirwa uye kuumba collid mushure mekutonhora.
Nhanho dzakanyungudika
Svina HPMC zvishoma nezvishoma mumvura, dzivisa kudurura zvakananga kuti udzivise kuunganidza;
Shandisa anomutsa kusanganisa zvisina mwero;
Gadzirisa mhinduro yekugadzirisa sezvinodiwa.
4. Zvinotangira kushandisa HPMC
DOSAGE Control: mune akasiyana mashandiro ekushandisa, iyo dosage yakanangana nekuita uye inoda kuedzwa maererano nezvinodiwa.
Mamiriro ekuchengetedza: Inofanirwa kuchengetwa mune inotonhorera, yakaoma, nzvimbo yekuvhunduka kuti udzivise kunyorova uye kupisa kwakanyanya.
Kudzivirirwa kwezvakatipoteredza: HPMC iri biodegradable uye haina kusvibisa nharaunda, asi iyo ichiri kufanira kushandiswa nenzira yakagadzirirwa kudzivirira kutambisa.
Kuenzanisa kwebvunzo: kana yakawedzerwa kune yakaoma masisitimu (senge cosmetics kana mishonga), kuenderana nezvimwe zvinoshandiswa zvinofanirwa kuedzwa.
5. Zvakanakira HPMC
Isina-chepfu, zvakatipoteredza zvine hushamwari, kuchengeteka kwakanyanya;
Zvinoenderana, inochinjika kune dzakasiyana siyana zvinodiwa zvido;
Kugadzikana kwakanaka, kunogona kuchengetedza kuita kwenguva yakareba.
6. Zvinetso Zvemashoko uye Mhinduro
Agglomeration Dambudziko: Teerera kutarisisa kuparadzaniswa pakushandiswa uye kusimudzira zvizere panguva imwe chete.
Nguva refu yekunyungudika: inopisa mvura yekunyepedzera kana manhamba ekukurudzira anogona kushandiswa kukurumidza kupaza.
Kuita Kwekuita: Teerera kutarisisa kunzvimbo yekuchengetedza kuti udzivise kunyorova uye kupisa.
Nekushandisa HPMC nesainzi uye rationally, yayo maitiro mazhinji, inogona kushandiswa zvizere kuti ipe mhinduro dzakakwirira dzeindasitiri akasiyana-siyana.
