專利匯可以提供Silicate foam structures and method of preparation專利檢索，專利查詢，專利分析的服務(wù)。并且A liquid silicate reactant, such as phosphoric acid, is absorbed in an amorphous reactant carrier, preferably calcium containing, to form a dry premix composition that is blended with an aqueous alkali metal silicate to form a moldable silicate mix. This mix is heated in a mold at a temperature sufficient to cause the removal of water therefrom, with small water gas bubbles being formed within and throughout the mix to produce a lightweight multicellular foam structure. The reactant and calcium ions are slowly leached from the carrier for reaction with the silicate during the foaming process, improving the water-insolubility and firmness characteristics of the resulting foamed structure. The rate of leaching is sufficiently slow, however, so as not to cause premature and rapid reaction with the silicate tending to reduce expansion of the structure. As a result, a low density foamed structure having a density of from about 3 to about 15, preferably less than 10, lbs/ft3 is obtained. The aqueous alkali metal silicate preferably comprises a combination of sodium silicate and potassium silicate, with the potassium silicate comprising from about 5 percent to about 10 percent by weight based on the total weight of alkali metal silicate employed.，下面是Silicate foam structures and method of preparation專利的具體信息內(nèi)容。
