Lub teeb pob zeb Additives | High-Performance Foaming Agents rau Cellular Concrete
Pob zeb yog cov khoom siv hauv tsev nrov uas tau siv dav hauv ntau yam kev tsim kho thoob ntiaj teb. Nws yog kev sib xyaw ntawm cov cement, dej, xuab zeb, thiab lwm yam ntaub ntawv uas yog ci los ua ib qho nyuaj thiab ruaj khov qauv. Txawm li cas los, muaj tej yam kev mob nyob rau hauv uas pob zeb xav tau additives.

Ib qho tseem ceeb uas cuam tshuam rau lub zog thiab kav ntev ntawm cov pob zeb yog nws qib dej. Raws li kev kho pob zeb, nws dhau los ntawm cov tshuaj tiv thaiv uas ua rau nws dhau los ua dej ntau dua. Cov txheej txheem no tuaj yeem ua kom qeeb lub sijhawm kho thiab ua rau muaj kev pheej hmoo ntawm kev tawg lossis tawg thaum raug kub kub.. Tiv thaiv qhov no, cov tuam txhab ua vaj tse feem ntau ntxiv cov tshuaj tiv thaiv cov dej noo xws li silicates lossis kaolin los txhim kho nws cov dej ntau thiab txhim kho nws lub zog thiab kav ntev..
Lwm yam uas cuam tshuam rau cov khoom ntawm pob zeb yog nws hom aggregate. Ntau hom aggregates muaj qhov sib txawv ntawm lub cev thiab lub zog, suav nrog qhov ntom ntom, compressive zog, thiab porosity. Piv txwv li,aggregate nrog lub ntiajteb txawj nqus siab yuav tsim kom muaj zog aggregate, tab sis kuj tseem tuaj yeem ua rau kev daws teeb meem raws sijhawm. Yog li ntawd, Nws yog ib qho tseem ceeb rau cov neeg cog lus ua vaj tse los xaiv cov hom sib sau tsim nyog uas ua tau raws li lawv qhov kev xav tau tshwj xeeb.
Ntxiv rau cov xwm txheej no, Qhov kub thiab txias plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov zoo tshaj plaws hydration thiab aggregate muaj pes tsawg leeg rau pob zeb. Thaum kub hauv qab 70 ° C (158° F), cov dej ntsiab lus ntawm cov qhob nce sai heev, ua kom nws tsis tshua muaj dej thiab muaj kev cuam tshuam rau kev tawg. Ntawm qhov tod tes, ntawm qhov kub thiab txias, hydration tus nqi txo, tso cai rau thiab nce tag nrho lub zog thiab durability ntawm cov pob zeb.
Piv txwv li, pob zeb yog feem ntau sim raws li British Standard (BS) 476, uas teeb tsa cov txheej txheem rau kev pom zoo hydration qib ntawm pob zeb. Qhov pom zoo hydration theem nws txawv nyob ntawm seb hom aggregate, tab sis feem ntau ntog ntawm 25% thiab 35%. Cov pob zeb uas muaj dej ntau dhau yuav nthuav dav heev thaum huab cua khov, thaum qhuav dhau yuav cog lus ntau dhau, ua rau tawg thiab tawg.

Zuag qhia tag nrho, qhov kub ntawm cov pob zeb xav tau cov khoom ntxiv yog ib qho tseem ceeb uas yuav tsum tau xav txog thaum tsim thiab ua vaj tse. Los ntawm kev ua tib zoo xaiv cov additives txoj cai thiab xaiv cov hom sib xyaw tsim nyog, cov neeg cog lus tuaj yeem xyuas kom lawv muaj zog, ruaj, thiab tiv taus ib puag ncig kev ntxhov siab xws li cua sov thiab ya raws.
