Lub teeb pob zeb Additives | High-Performance Foaming Agents rau Cellular Concrete
Cement foaming agent, hais txog yuav txo tau cov kua nto nro, tsim ib tug loj tus naj npawb ntawm uniform thiab ruaj khov ua npuas ncauj, siv los tsim ua npuas ncauj ua npuas ncauj admixture.Foaming tus neeg sawv cev yog ib yam khoom uas muaj peev xwm tsim tau ib tug loj tus naj npawb ntawm foams thaum nws aqueous tov yog nkag mus rau hauv cov huab cua nyob rau hauv lub mechanical quab yuam.. Cov tshuaj no yog surfactant lossis surfactant, thiab tsuas yog ib feem me me ntawm nws tuaj yeem siv tau hauv cov pob zeb ua npuas, uas yog txiav txim los ntawm cov yam ntxwv thiab kev xav tau ntawm foamed pob zeb.
Cov ntim sib txawv ntawm cov kua ua npuas dej thiab cov dej tsis tu ncua-cement quantitative relation (0.55) lawv yeej tsis npaj ib pab pawg ntawm cov pob zeb ua npuas ncauj los ntawm pre-formed foaming. Cov kua foams muaj xws li supermolecule foaming additive, dej thiab cua, tsim los ntawm cov neeg raug tsim txom ua npuas dej generator, tau tov nrog hydraulic cement - dej ncua kev kawm. Qhov cuam tshuam ntawm foaming tus neeg sawv cev concentration thiab nws cov microwave thiab inaudible kev kho mob tau soj ntsuam nyob rau hauv kev hwm rau lub foam stability, qhov ntom ntom, microstructure thiab ensuing compressive zog. Micrographs los ntawm kev siv lub tshuab kuaj kab mob (KOJ) lawv yeej tsis tau txheeb xyuas qhov nruab nrab pore loj. Cov crystalline ib feem muaj pes tsawg leeg ntawm cov qauv raug soj ntsuam los ntawm XRD tsom xam thiab coincidental TG-DTA yeej tsis tau kawm lawv thermal stability.. attenuate pore loj uas tso nyiaj rau kev txhim kho lub zog compressive yog kev daws teeb meem nyob rau hauv cov qauv npaj nrog qis concentration ntawm microwave thiab inaudible kho foaming tus neeg saib xyuas. Tsawg concentration ntawm foaming tus neeg sawv cev nws tus kheej conjointly muaj kev cuam tshuam zoo rau lub suab ntawm lub froth. Txawm li cas los, nws lub hwj chim tsis yog li ntawd txawv.
Foamed pob zeb yuav raug tsim los ntawm cov txheej txheem ua ntej ua npuas ncauj lossis cov txheej txheem sib xyaw ua npuas. nyob rau hauv cov txheej txheem pre-foaming, ib tug tsim nyog foaming neeg sawv cev yog tov nrog dej, thiab yog li ntawd cov npuas dej ua ke nrog muab tshuaj txhuam los yog tshuaj khib. Lub caij no, nyob rau hauv cov txheej txheem mix-foaming, tus neeg sawv cev foaming yog intercalary rau lub ncua, thiab yog li ntawd qhov sib tov yog whisked rau hauv ib qho chaw ruaj khov uas muaj qhov ceev ceev. Kev tsim kom ruaj khov sib xyaw ntawm foamed pob zeb nyob ntawm ntau yam, zoo li kev xaiv ntawm tus neeg sawv cev foaming, lub tacticwont los npaj cov froth kom tau raws li huab cua-void faib, xaiv cov ntaub ntawv, txoj kev sib tov style, thiab yog li ntawd cov khoom ntawm foamed pob zeb. Ntau hom foaming agents yuav tsis tsim cov pob zeb ua npuas ncauj, ua ke nrog detergents, resin xab npum, kua nplaum resins, saponin, thiab hydrolyzed proteins, zoo li albuminoid thiab cov ntaub ntawv zoo sib xws.
Cie-China.org yog tus thawj coj ua npuas dej ua ke muab kev pabcuam ua npuas ncauj ua npuas ncauj, superplasticizer,ua npuas ncauj qhob zog enhancer rau lub teeb yuag pob zeb, CLC blocks. Yog koj tab tom nrhiav foaming tus neeg sawv cev, thov koj txhob xav li cas tiv tauj peb.
