Lub teeb pob zeb Additives | High-Performance Foaming Agents rau Cellular Concrete
superplasticizer ua haujlwm li cas
Kev tsim khoom siv pob zeb yog ua raws cov tshuaj tiv thaiv uas khi dej thiab cov cement nrog cov khoom sib xyaw zoo (xuab zeb los yog crushed pob zeb) thiab coarse aggregates. Cov txheej txheem no tsim cov hydrated cement paste uas ruaj khov thiab ntom txaus rau kev sib txuas nrog cov hlau reinforcing.
Nws yog ib qho tseem ceeb uas yuav tsum tau ntxiv cov dej kom raug txhawm rau txhawm rau ua tiav qhov xav tau lub zog thiab kav ntev ntawm cov khoom kawg. Cov dej ntau dhau tuaj yeem txo qhov ua tau zoo ntawm cov pob zeb.
Muaj ntau ntau hom admixtures uas tuaj yeem siv los hloov cov khoom ntawm pob zeb thiab txhim kho nws lub peev xwm ua tau zoo nyob rau ntau qhov xwm txheej.. Lawv tuaj yeem txo lub sijhawm teeb tsa ntawm pob zeb, nce nws lub zog thaum ntxov, txo nws cov ntsiab lus dej los yog qeeb nws cov dej ntws.
Lawv kuj tseem siv tau los ua kom cov flowability ntawm pob zeb. Qhov no yog ua tiav los ntawm dispersing cov cement hais nyob rau hauv kev sib tov kom lawv fluidity.
Qhov no yog ib txoj hauv kev zoo heev los txhim kho kev ua haujlwm ntawm pob zeb. Qhov no yog qhov laj thawj tseem ceeb vim li cas plasticizers ntxiv rau cov pob zeb sib xyaw.
Lub dispersive kev txiav txim ntawm plasticizers zoo heev txhim kho lub workability ntawm pob zeb ntawm ib tug muab dej-cement ratio thiab dej cov ntsiab lus., xws li tias nws tuaj yeem muab tso nrog me ntsis kev siv zog thiab xyaum tsis muaj los ntshav lossis cais tawm.
Superplasticizers yog ib pawg tshiab ntawm cov pob zeb sib xyaw uas tuaj yeem ntxiv rau cov pob zeb sib xyaw. Lawv tuaj yeem txo cov dej ntsiab lus ntawm qhov sib xyaw kom txog li 30% thiab tuaj yeem txhim kho nws txoj haujlwm ua haujlwm los ntawm kev ua kom poob qis. Lawv tuaj yeem siv rau hauv ob qho tib si tshiab thiab cov pob zeb tawv tawv kom txo tau cov ntsiab lus dej lossis lub sijhawm teeb tsa.
