Tsis-toxicity
HydroxyPropyyl methylulose yog cov biocompiellulose uas feem ntau tsis muaj tshuaj lom thiab haum rau kev siv hauv teb nrog kev nyab xeeb txog kev nyab xeeb xws li tshuaj thiab khoom noj.
Zaj duab xis-ua cov cuab yeej
Nws tuaj yeem tsim cov zaj duab xis uniform nyob rau saum npoo ntawm substrate, nrog qee cov yeeb yaj kiab nro thiab noo noo tsis kam, thiab feem ntau siv rau hauv cov txheej txheej thiab cov nplaum.
Emulsification thiab dispersibility
HydroxyPropyyl methylcellulose tuaj yeem siv los ua emulsifier pab kom cov roj thiab dej sib xyaw thiab tsim cov khoom ruaj khov. Nyob rau tib lub sijhawm, nws kuj tseem muaj qhov ua tau zoo dispernitibility, uas tuaj yeem pab kom tshem tawm cov nplais kom cov khoom ua kuayees.
Rheological Khoom
Nyob rau ntawm cov sib txawv shear tus nqi, hydroxypropyl methylcelulose qhia tsis yog-Newtonian kua dej. Raws li cov shear tus nqi nce ntxiv, qhov viscosity ably txo qis. Cov cuab yeej rheological ua rau nws haum rau ntau yam kev ua haujlwm.
Lub ntsiab siv
Kev Tsim Kho Kev Tsim Kho
Hauv kev tsim kho kev tsim kho, HPMC feem ntau siv los ua cov tuab thiab dej khaws cia rau cov cement cug. Nws tuaj yeem txhim kho kev tsim kho ntawm cug tshuaj khib, txhim kho cov haujlwm ua haujlwm thiab kev sib sau ua ke lub sijhawm tsim kho thiab tiv thaiv cov cement los ntawm kev tawg. Ib qho ntxiv, nws kuj tseem tuaj yeem txhim kho cov nplaum thiab dej tsis kam ntawm cov txheej ntsa.
Kws Tshuaj Kho Mob
HPMC yog dav siv nyob rau hauv kev npaj tshuaj, tshwj xeeb tshaj yog nyob rau hauv kev npaj cov ntsiav tshuaj, thiab lwm yam siv cov tshuaj lom neeg vim nws qhov zoo biocompatibility thiab tsis muaj kuab lom. Nws yog feem ntau siv ua cov nplaum, txhawb nqa tus neeg sawv cev thiab cov khoom siv txheej hauv cov ntsiav tshuaj. Nyob rau hauv qhov muag poob, nws feem ntau siv los ua cov roj nplua nyeem los ua kom muaj cov tsos mob qhuav.
Kev Lag Luam Khoom Noj
Hauv kev ua zaub mov noj, HPMC tuaj yeem raug siv los ua cov tuab, emulsifier, stabilizer, thiab lwm yam thiab nce cov kev ntxhib los mos thiab ruaj khov ntawm cov zaub mov. Piv txwv li, feem ntau nws yog feem ntau siv hauv cov khoom noj muaj roj tsawg ua ib qho muaj roj hloov lossis hauv cov mis nyuj khov txhawm rau txhim kho nws cov qauv.
Saib Xyuas Tus Kheej thiab Tshuaj pleev ib ce
HPMC ua si lub luag haujlwm tseem ceeb hauv cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej, feem ntau yog cov tuab, stabilizer thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier. Nws tuaj yeem txhim kho lub zog rheological ntawm cov khoom gel thiab ua rau lawv muaj kev xav zoo. Hauv cov khoom lag luam xws li cream, tshuaj ntxhua khaub noom, tshuaj ntxhua, thiab txias, HPMC tuaj yeem txhim kho kov thiab tsos ntawm cov khoom.
Textile Kev Lag Luam Textile
Hauv kev lag luam textile, HPMC tuaj yeem siv los ua slurry rau cov ntawv kom lawv cov kev ua haujlwm ua haujlwm thiab luam tawm thiab cuam tshuam cov teebmeem. Nws tuaj yeem txhim kho lub wrinkle tsis kam thiab puas tsis kam ntawm cov ntaub, thiab xyuas kom cov khoom sib cais ntawm cov neeg ua haujlwm, txhim kho cov tsos zoo ntawm cov khoom.
Cov Tshuaj Txhua Hnub
HydroxyPropyyl methylulose tseem dav siv cov tshuaj txhua hnub xws li cov tshuaj pleev ib ce xws li cov khoom siv, thiab lwm yam kev ua haujlwm thiab dej tsis kam.
Ntawv thiab Txheej Txheem
HPMC yog siv los ua cov tuab thiab tsis sib xws nyob rau hauv cov txheej txheem ntawm cov ntawv tsim thiab txheej ntau lawm. Nws tuaj yeem txhim kho lub qab ntov thiab noo noo tiv taus ntawm daim ntawv, thiab tib lub sijhawm txhim kho cov dispersion ntawm cov paintings hauv cov paintings thiab tiv thaiv cov nag lossis daus.
Kev Lag Luam Kev Lag Luam
Hauv kev ua liaj ua teb
Raws li ib qho kev sib txuas thiab dav siv polymer compound, hydroxypropylulose tau siv dav hauv ntau qhov kev lag luam vim nws lub cev nqaij daim tawv thiab tshuaj lom neeg. Seb puas nyob hauv kev tsim kho, tshuaj, zaub mov, tshuaj pleev ib ce, textiles, kev ua liaj ua teb thiab lwm thaj chaw, HPMC ua lub luag haujlwm tseem ceeb. Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis yav tom ntej, nws daim ntawv thov teb thiab peev txheej yuav raug nthuav ntxiv.
