HPMC YB 515M

EipponCell HPMC YB 515M, tshwj xeeb yog tsim los rau cov txheej txheem pobzeb nplaum daim ntaub ntawv, muaj cov khoom nram qab no:

Kev cuam tshuam rau lub sijhawm qhib ntawm pobzeb nplaum

Thaum cov latex hmoov thiab cellulose ether HPMC muaj nyob rau hauv ib tug ntub mortar, RDP hmoov muaj ib tug muaj zog binding zog nrog cov cement hydration khoom, thaum cellulose ether feem ntau cuam tshuam rau cov kua interstitial, cuam tshuam lub viscosity thiab teem sij hawm ntawm lub mortar.

RDP hmoov nthuav tawm txhim kho kev sib txuas rau cov khoom siv cement hydration, thaum cellulose ether feem ntau cuam tshuam rau cov kua nruab nrab, cuam tshuam rau cov viscosity mortar thiab teem sijhawm.

Kev sib koom ua ke ntawm latex hmoov thiab cellulosic ether HPMC nyob rau hauv ib lub mortar ntub cuam tshuam cov khoom ntawm mortar, nrog RDP hmoov muaj ib tug loj binding zog thiab cellulosic ether cuam tshuam lub viscosity thiab teem sij hawm los ntawm nws muaj nyob rau hauv lub interstitial kua.

Kev cuam tshuam rau lub zog rub tawm ntawm cov nplais nplaum

Cellulose ether nyob rau hauv mortar tsis tsuas yog muab cov khoom muaj txiaj ntsig, tab sis kuj tseem ncua sijhawm hydration dynamic ntawm cov cement los ntawm adsorbing mus rau cov khoom hydrated es tsis txhob ntawm cov ntxhia hauv thawj theem.Cov nyhuv retardation no yog vim qhov txo qis ntawm cov ions nyob rau hauv cov pore tov vim qhov nce viscosity tshwm sim los ntawm cellulose ether.

Lub xub ntiag ntawm cellulose ether nyob rau hauv cov cement systems retards hydration kinetics los ntawm adsorbing cov khoom hydrated es tsis txhob ntawm cov pob zeb hauv av thawj theem, thaum tseem ua rau cov viscosity ntawm pore tov, yog li txo cov ion zog thiab ntxiv qeeb cov txheej txheem hydration.

Cellulose ether's retardation nyhuv ntawm cov cement hydration feem ntau yog ua tiav los ntawm nws cov adsorption mus rau cov khoom hydrated thiab tom qab nce hauv cov viscosity ntawm cov pore tov, uas cuam tshuam ion txav mus los thiab ncua tag nrho cov dej dynamics.
