Lub teeb pob zeb Additives | High-Performance Foaming Agents rau Cellular Concrete
Ua npuas ncauj, hauv chemical science, ib tug sib tov system (i.e., ib tug dispersion ntawm hais nyob rau hauv ib tug heev nruam nruab nrab) nyob rau hauv uas cov hais ar gas npuas thiab cov nruab nrab yuav ua tau ib tug kua. Lub sij hawm kuj tseem siv tau rau cov khoom siv hauv lub cev hnyav heev ntawm tes spongy lossis hom tawv. Cov kua nplaum feem ntau yog tsim los sib piv ntev-ntev-xws li., rau qhov cub sib ntaus sib tua-los ntawm kev ntxiv qee yam khoom, hu ua stabilizer, uas forestalls los yog retards lub union ntawm cov pa npuas npuas. Ntawm cov khoom zoo uas ua raws li ua npuas ncauj stabilizers, qhov zoo tshaj plaws illustrious ar soaps, tshuaj ntxuav tes, thiab proteins. Cov protein, raws li qhov tshwm sim ntawm lawv yog edible, pom dav siv raws li foaming agents hauv cov khoom noj xws li topping, khoom qab zib (ua los ntawm gelatin thiab qab zib), thiab topping (los ntawm qe dawb). the froth accustomed combat oil fires consists of bubbles of carbonic acid gas (liberated from bicarbonate and metallic element sulfate) stabilised by dried blood, kua nplaum, or different low cost protein-containing materials. brewage foam is believed to be stabilised by the mixture constituents gift, that embody proteins and carbohydrates. Foaming is also undesirable, as in lubricating oils, and its hindrance isn’t perpetually straightforward. binary compound foams sometimes will be broken by treatment with little amounts of sure alcohols.
Ua npuas ncauj stabilizer plays a vital role within the synthesis of geopolymer foam materials (GFMs). to raised clarify the consequences of salt primarily based foam stabilizer (CSFS) on pore characteristics and thermal conduction of materials, GFMs npaj nrog 0-2% CSFS tau tshawb xyuas rau kev ua npuas ncauj, compressive zog, qhov ntom ntom, geopolymerization khoom, pore faib, thiab thermal conduction. Cov txiaj ntsig qhia tau tias (1) lub sij hawm froth thiab pib lub sij hawm teem match optimally nrog 1.0% CSFS cov ntsiab lus. Thiab lub sijhawm no, lub sij hawm froth thiab npuas ntim ntawm GFMs tau redoubled kom meej meej los ntawm plaub caug ob.8% thiab 28.6% ntau ntau. (2) 28 d compressive lub zog ntawm GFMs nrog ib qho ntom ntom ntawm xoom.31 g / cm3 ntawm ib qho.0% CSFS cov ntsiab lus yog hauv qab, 1.45 MPa, txawm li cas los xij tseem siab dua qhov zoo ntawm ib qho.0 MPa rau xoom.325 g / cm3 raws li Tuam Tshoj National Standards GB11968-2006. (3) CSFS tso tawm cov txiaj ntsig txwv ntawm tus lej lossis ntau yam khoom siv geopolymerized. (4) Nrog CSFS/FA nce ntawm zero.5% mus rau 2.0%, Tus naj npawb ntawm macroscopic scale pores loj li 10-100 µm sawv tseem ceeb ces poob kom meej., Txawm li cas los xij tseem zoo li tus qauv nrog CSFS dawb. tus naj npawb ntawm microscopic scale pores loj 10-100 nm loj hlob stably. (5) Zuag qhia tag nrho, 1.0% CSFS optimized pore characterization zoo nrog qhov loj tshaj plaws porousness, 82%, Txhua qhov chaw thermal conduction ntawm GFMs mus txog lub hom phiaj hauv qab ntawm xoom.095 W/(m K).
