Lub teeb pob zeb Additives | High-Performance Foaming Agents rau Cellular Concrete
Lightweight concrete additives can be used to replace dense natural aggregates in structural concrete. Cov additives no tuaj yeem txo cov nqi ntawm cov khoom siv thiab tuav. Lawv tuaj yeem ua kom cov thermal rwb thaiv tsev ntawm cov pob zeb thiab txhim kho nws cov hluav taws kub.
Foamed pob zeb yog ib qho ntawm feem ntau siv cov pob zeb sib sib zog nqus. Nws yog tsim los ntawm cov txheej txheem pre-forming. Tus neeg sawv cev foaming qhia randomly faib pa npuas rau hauv qhov sib tov. Qhov no ua rau qis dua.
Cov khoom tseem ceeb ntawm cov qhob foamed yog cov foaming agent thiab stabilizer. Tus neeg sawv cev stabilizing feem ntau yog ntxiv rau hauv slurry ntawm foamed qhob batch.
Ib yam li txo tus nqi ntawm cov khoom siv, cov additives no tuaj yeem txhim kho cov qauv thiab kev ua haujlwm ntawm cov pob zeb sib sib zog nqus. Siv cov additives no tuaj yeem pab txo qis cov kev cai steel rau qhov project.
Ntau qhov kev tshawb fawb tau ua los tshawb xyuas lub zog compressive ntawm ntau hom kev sib sib zog nqus pob zeb. Nws tau raug pom tias qhov ntom ntom ntawm pob zeb hauv qhov ntau ntawm 350 rau 50 kg / m3 yog txais.
Txawm li cas los, cov densities yog me ntsis qis dua cov nyob rau hauv cov ntaub ntawv ntawm ib txwm hnyav pob zeb. Qee qhov kev tshawb fawb tau tshawb xyuas qhov cuam tshuam ntawm nanosilica ntawm qhov ntom ntawm foamed pob zeb.
Lwm txoj kev tshawb fawb tau tshawb xyuas qhov cuam tshuam ntawm cov khoom siv cementitious ntxiv ntawm kev ua haujlwm ntawm ultra-lub teeb yuag foamed pob zeb. Cov kws sau ntawv pom tau hais tias kev suav nrog cov khoom xyaw no txo qis tus nqi ntawm cov pob zeb.
Tsis tas li ntawd xwb, kev siv nanosilica txhim kho lub zog ntawm cov pob zeb los ntawm kev ua kom zoo dua cov qauv pore. Ntxiv rau, Qhov ntom ntawm cov pob zeb tau nce nrog kev koom ua ke ntawm nanosilica.
