TUS CWJ PWM LOS TXHEEJ TXHEEM TIMEOF SNF SUPERPLASTICISER RAU MICROSILICA-SULPHATE LUB CEMENTS
Jan 15, 2020
Cov Kws Tshaj Lij Nruab Nrab yog linear polymers nrog hydrophobic thiab ionizable hydrophilic polar pawg. Qhov ntawm hydrophilic thiab hydrophobic pawg yuav tsum ua kom tsawg kawg surfactancy kom tsis txhob foaming thiab huab cua nkag los ntawm admixtures. Qhov sib ntxiv ntawm cov nyiaj tsawg ntawm superplacticizer pab txhim kho kev ua haujlwm, tab sis lawv feem ntau cuam tshuam nrog kev ua kom muaj zog, tsis xav tau qhov xav tau sai ntawm cov teeb tsa ua kua nplaum. Cov neeg hloov khoom siv feem ntau siv hauv cov tshuab qhob rau peb lub hom phiaj sib txawv lossis kev sib txuas ntawm cov no.
txhawm rau ua kom lub chaw ua haujlwm tsis hloov pauv cov khoom sib xyaw ua ke los txhim kho cov yam ntxwv ntawm kev sib txuam,
- txhawm rau kom txo cov dej uas xav tau ntawm cov qauv txheej txheem kom xwm yeem txhawm rau txhawm rau ua kom lub zog ntawm cov qhob
- kom txo ob qho dej thiab xis mas nyob rau ntawm qhov kev ua haujlwm tau txais txiaj ntsig txhawm rau txhawm rau txuag cov cement thiab txo cov nkag, shrinkage thiab thermal cov kab mob tshwm sim los ntawm cov cua sov ntawm cov dej cement.
