Lub teeb pob zeb Additives | High-Performance Foaming Agents rau Cellular Concrete
Dab tsi PSI yog qhov siab thaum ntxov?
Lub zog compressive ntawm pob zeb yog feem ntau ntsuas hauv phaus ib square inch (psi). Nws yog thawj qhov kev ntsuas uas siv los ntsuas qhov ua tau zoo ntawm kev sib xyaw ua ke. Lub pob zeb uas muaj psi siab dua yog qhov muaj zog dua, yog li nws yuav ua tau ntev dua thiab kav ntev dua.
Dab tsi yog qhov zoo tshaj psi rau pob zeb?
Feem ntau ntawm psi rau cov qauv pob zeb sib txawv, tab sis feem ntau nws pib ntawm 3,500 psi thiab nce mus rau 5,000 psi los yog ntau dua. Qhov no psi feem ntau xav tau rau cov pob zeb pob zeb, slabs ntawm qib, suspended slabs, thiab kab teeb. Nws tseem xav tau rau kev loj pavements, uas xav tau psi ntawm 4,000 rau 5,000 psi tiv thaiv lub khov / thaw cycles.
Dab tsi yog qee txoj hauv kev kom nce psi ntawm pob zeb?
Ua kom qhov kub thiab txias ntawm cov pob zeb sib xyaw tshiab tau paub tias yuav ua rau kom muaj zog ntawm cov pob zeb. Txawm li cas los, steam curing yog kim thiab anti-eco-phooj ywg.
Ua chemical admixtures thiab ntxiv cov ntaub ntawv cementitious ua kom lub zog thaum ntxov ntawm pob zeb?
Qee cov tshuaj sib xyaw, xws li calcium chloride, tau pom kom ceev lub zog thaum ntxov ntawm pob zeb. Cov admixtures no feem ntau yog siv los txo cov dej rau cement piv rau hauv pob zeb.
Ua ncua sij hawm moist curing los yog tso rau hnub kub nce psi ntawm pob zeb?
Qee lub koom haum tau pom zoo kom tsis txhob muab tso rau hnub kub, batching nrog dej khov, thiab muab tso rau hmo ntuj. Tag nrho cov kev ua no nce psi ntawm pob zeb, tab sis tag nrho lawv kuj tseem tuaj yeem ua rau tawg los ntawm kev ziab kom qhuav.
