HPMC YB520M

EipponCell HPMC YB 520M yog cov khoom muaj txiaj ntsig zoo rau kev siv cov cement-based plaster, muab cov khoom hauv qab no:

Kev faib tawm muaj txiaj ntsig: Thaum HPMC yaj hauv dej, nws nthuav tawm cov haujlwm saum npoo av, kom ntseeg tau tias muaj kev sib faib ntawm cov khoom siv cementing nyob rau hauv mortar system.Ua raws li kev tiv thaiv colloid, HPMC envelops khoom hais, tsim ib txheej ntawm lawv cov txheej txheej ..

Kev tuav dej: Vim nws cov qauv molecular tshwj xeeb, cov tshuaj HPMC pab khaws cov dej hauv cov mortar, maj mam tso nws mus rau lub sijhawm ntev .. lub substrate.. Cov dej khaws cia tseem nyob rau saum npoo ntawm cov khoom tshiab, txhawb cov cement hydration thiab thaum kawg txhim kho lub zog kawg ntawm plaster.

Stability thiab compatibility: HPMC pom kev ruaj ntseg rau ob qho tib si acid thiab alkali ib puag ncig.. Nws cov kua aqueous tseem ruaj khov nyob rau hauv pH ntau ntawm 2 mus rau 12. me ntsis nce nws viscosity.

Kev Txhim Kho Kev Txhim Kho Kev Ua Haujlwm: Qhov sib ntxiv ntawm HPMC ua rau muaj txiaj ntsig zoo rau kev tsim kho ntawm mortars.. Cov mortar uas tau tshwm sim muaj cov nyhuv lubricating, feem ntau tau piav qhia tias yog "roj," uas ua rau muaj kev puv puv ntawm phab ntsa pob qij txha, smoothens saum npoo, thiab txhawb kev sib txuas ntawm cov vuas. los yog cib thiab lub hauv paus txheej.Tsis tas li ntawd, lub xub ntiag ntawm HPMC ncua lub sijhawm ua haujlwm, ua rau nws tsim nyog rau kev tsim kho loj.
