Additius de formigó lleuger | Agents espumants d'alt rendiment per al formigó cel·lular
Els agents espumants són substàncies que faciliten la formació d'escuma reduint la tensió superficial de l'aigua. Aquestes substàncies s'utilitzen en una àmplia gamma de productes per a la cura personal, incloent pastes de dents, sabons, xampús, desodorants, locions, i detergents.
Chemical foaming agents are inorganic or organic compounds that are used to produce medium to high density foams. Their primary purpose is weight reduction. Some of these foaming agents are also used in gas well stimulation.
When a foaming agent is added to a composite conducting foam agent material, the mixture is stirred in a low temperature for 10-20 minuts. The mixture is then poured into the mold. The cyclopentane foaming process is one method that saves energy. To reduce cost, the ring temperature should be kept low during the molding process.
The most common foaming agents are sodium lauryl sulfate and coco-glucoside. No obstant això, a new class of chemical foaming agents, called acyl glucamides, has been introduced. They are said to produce foam volume comparable to SLS.
Chemical foaming agents are often combined with physical blowing agents to create medium- to high-density foams. When selecting a foaming agent, it is important to consider the compatibility of the polymer and decomposition products.
Com a resultat, different foaming agents have different water requirements. A més, the water temperature can also affect the results. Water temperatures between 10 i 40 degrees Celsius are usually appropriate.
Foaming agents are also used to aid in the recovery of drowned water. These substances can be used to clean out a water well or dispose of waste.
