Khoom Description
Headcel HPMC rau Txheej
Hydroxypropyl Methyl Cellulose tshwj xeeb rau txheej.
Cov khoom lag luam raws li CP, USP thiab EP.
Headcel HPMC rau Txheej yog tsim tshwj xeeb rau Txheej cov khoom siv tshuaj, uas muaj cov dej zoo solubility, dispersion, thickening, dej tuav thiab zaj duab xis tsim cov khoom, lub txheej zaj duab xis nws tsim yog xim tsis muaj xim, tasteless, tawv thiab zoo transparency, vim nws yog dav siv los ua tshuaj txheej cov ntaub ntawv.
Pom zoo daim ntawv thov thaj chaw thiab kev ua tau zoo yog raws li hauv qab no:
1. Cov khoom yog tsim rau txheej zaj duab xis txog cov khoom.
2. Nrog rau cov dej txias solubility zoo heev, cov khoom yuav txo tau kev siv cov organic hnyav
3. Cov khoom muaj peev xwm tiv taus noo noo thiab oxygen permeability, tuaj yeem txhim kho kev ruaj ntseg ntawm cov tshuaj.
4. Nrog rau kev siv dav, cov khoom lag luam tsis muaj qhov cuam tshuam cuam tshuam thiab tsis muaj kev cuam tshuam, kev ruaj ntseg siab.
5. Cov khoom lag luam tuaj yeem tsim cov zaj duab xis tawv thiab txuas ntxiv thiab txheej txheej ntawm txhua yam ntawm cov ntsiav tshuaj, thiab cov cim saum npoo tseem tuaj yeem pom.

Peb Qhov Kev Pabcuam
Ntawm Lub taub hau, peb muab cov kev pabcuam hauv qab no rau cov neeg siv khoom:
Kawm txog cov khoom ntawm cov khoom sib tw.
Pab tus neeg siv khoom kom nrhiav tau qib sib xws sai thiab meej.
Formulation Service los txhim kho kev ua tau zoo thiab tswj tus nqi, raws li txhua tus neeg siv cov huab cua tshwj xeeb, cov xuab zeb tshwj xeeb thiab cov cement, thiab cov cwj pwm ua haujlwm tshwj xeeb.
Ntawm Lub taub hau, peb muaj ob qho tib si Chemical Lab thiab Application Lab kom ntseeg tau tias txhua qhov kev txiav txim siab zoo tshaj plaws
Chemical labs yog tso cai rau peb los soj ntsuam cov khoom xws li viscosity, humidity, tshauv theem, pH, cov ntsiab lus ntawm methyl thiab hydroxypropyl pawg, hloov degree thiab lwm yam.
Daim ntawv thov lab yog tso cai rau peb ntsuas lub sij hawm qhib, dej tuav, adhesion zog, plam thiab sag kuj, teem sij hawm, workability thiab lwm yam.
