Cov nyhuv ntawm hydroxypropyyl methylcellose ntawm kev ua vaj tse lub zog

HydroxyPropyyl methylcellose (HPMC) yog cov tuab tuab siv thickener thiab dej-khaws tus neeg sawv cev, siv nyob rau hauv cov pob zeb. Nws tuaj yeem ua ncaj qha rau lub zog ntawm cov pob zeb ua los ntawm kev kho nws cov khoom siv hluav taws xob, cov khoom siv sijhawm.

Txhim kho lub zog thaum ntxov compressive
Cov kev tshawb fawb tau pom tias cellulose modifiers ntawm cov chaw viscosities sib txawv yuav nce thaum ntxov compressive zog ntawm cov pob zeb hauv cov roj av. Qhov qis dua viscosity, qhov ntau dua kev txhim kho. Tus nqi tsim nyog ether ether tuaj yeem txhim kho kev ua haujlwm ntawm kev ua haujlwm thiab nce lub zog compressive.

Txhim kho cov haujlwm thiab dej ua haujlwm khaws
HydroxyPropyyl methylcellulose tuaj yeem txhim kho kev ua haujlwm thiab dej khaws cia ntawm cov pob zeb ua kom muaj zog, yog li pab txhawb kev cog lus thiab lub zog ntawm cov qhob. Piv txwv li, thaum cov ntsiab lus ntawm hydroxypropylulose yog 0.04%, cov qhob muaj cov kev ua haujlwm zoo tshaj plaws, cov ntsiab lus cua yog 2.6%, thiab lub zog compressive nce siab tshaj plaws.

Cuam tshuam cov fluentity thiab nthuav dav ntawm cov pob zeb ua
Qhov ntau npaum li cas ntawm hydroxypropyl methylcellose muaj qhov cuam tshuam tseem ceeb ntawm nws cov nyhuv hauv pob zeb. Qhov tsim nyog ntawm hydroxypropylencellulose (piv txwv li, ntau dua (piv txwv li, ntau dua 0.08%) yuav ua rau muaj kev nthuav dav ntawm kev ua vaj tse kom maj mam poob. , uas yuav cuam tshuam cuam tshuam rau lub zog ntawm kev ua vaj tse.

retarding nyhuv
HydroxyPropyyl methylulose muaj cov nyhuv retarding, uas tuaj yeem ua rau cov pob zeb ua kom muaj kev ua haujlwm ntev dua, cia li pab txhim kho kom txhim kho lub compactness thiab lub zog ntawm qhob.

Cov cawv ntawm hydroxypropy muag methylcellulose on lub zog ntawm qhob yog multifaceted. Tus nqi tsim nyog ntawm hydroxypropyf me me ntawm cov pob zeb khov kho ntawm cov pob zeb ua kom zoo, yog li kev pab txhim kho kev sib cog lus thiab tag nrho lub zog ntawm cov qhob. Txawm li cas los xij, kev sib koom ua ke ntau dhau yuav muaj qhov tsis zoo rau cov xim av thiab nthuav dav ntawm cov pob zeb ua kom zoo rau lub zog ntawm cov pob zeb ua. Yog li ntawd, thaum siv hydroxypropyil methylcellulose, nws yog ib qhov tsim nyog los xaiv ib qho tsim nyog noj raws li qhov xwm txheej tshwj xeeb.
