Lub teeb pob zeb Additives | High-Performance Foaming Agents rau Cellular Concrete
A cellular qhob foaming agent yog ib qho ntawm cov khoom xyaw tseem ceeb rau cellular lightweight concrete. Qhov no foamed pob zeb yog npaj los ntawm kev siv cov roj-forming chemicals ntawm tus neeg sawv cev foaming ntawm cov qib ntsuas thiab sib tov nrog cov cement slurry los tsim cov qauv kaw..
Lub cellular qauv ntawm cov pob zeb muaj cov cement, dej, aggregate thiab cua voids nrog ib tug capillary pore ntim txog li 70%. Nws yog lub teeb nyob rau hauv hnyav thiab heev compressive-resistant.
Nws yog ib qho tseem ceeb kom nkag siab txog microstructure ntawm cellular pob zeb vim nws cuam tshuam rau nws cov thermal kuj, sorptivity coefficient thiab mechanical zog. Nws tseem muaj txiaj ntsig zoo rau kev nqus dej.
Ntau yam foaming agents tau raug sim los txiav txim lawv lub zog ntawm cov khoom ntawm cellular pob zeb. Cov txiaj ntsig tau qhia tias hom foaming tus neeg sawv cev muaj qhov cuam tshuam loj rau ob qho tib si thermal thiab sorptivity tab sis tsawg dua ntawm kev cuam tshuam rau cov khoom siv kho tshuab..
Foaming agents nrog rau qhov sib piv siab dilution tau pom tias muaj kev ruaj khov dua li cov uas muaj qhov sib piv qis dua.. Qhov no yog vim hais tias tus neeg sawv cev foaming tuaj yeem khi cov dej hauv ib qho kev faib tawm thoob plaws hauv lub npuas. Qhov kev sib khi ntawm cov dej no ua rau cov pob zeb ua rau lub sijhawm luv dua thiab ua tiav lub zog ntau dua.
Qhov sib piv ntawm cov dej-cement yog qhov tseem ceeb hauv kev txiav txim siab qhov ntom thiab lub zog ntawm cov pob zeb ua npuas sib xyaw. Qhov ntom thiab lub zog ntawm cov pob zeb poob qis heev thaum cov dej-cement piv ntau dua 0.5. Txawm li cas los, qhov siab tshaj plaws txhua yam lub zog ntawm lub cellular pob zeb yuav ua tiav thaum cov dej-cement piv ntawm 0.4 thiab 0.5.
