专利汇可以提供Synthetic light-weight material and process and system for manufacturing same专利检索，专利查询，专利分析的服务。并且Synthetic light-weight material suitable for use in building, construction, building products, packaging, insulation, soil conditioning, and the like, formed of four ingredients in selective quantities depending upon the desired bulk density of the final product, the four ingredients being a delayed-action, heat-triggered neutralizer, an expander controller, anhydrous sodium silicate, and liquid sodium silicate; the expander controller being omittable when extremely light bulk density of less than about 1.5 lb. per cu. ft. is desired. In one final form, the particles are extremely expanded to a low bulk density for use as a very light-weight aggregate for mixture with cement to form light building blocks, having excellent sound-absorbing characteristics, to form fire-resistant partitions, and fireresistant or sound-absorbent coatings. In another form, the bulk density of the particle aggregate is retained at a high value for ease and economy of shipment to the user''s site where it is subsequently passed through a heat expansion to drastically reduce its density to the desired low value for use. The process steps and system of equipment enable the amount of expander controller utilized to be varied dependent upon the severity of the subsequent aggregate-cement mixing so that the light particles are resistant to abrasive and commingling treatment during the mixing.，下面是Synthetic light-weight material and process and system for manufacturing same专利的具体信息内容。

11. The process of producing light-weight aggregate as claimed in claim 10, wherein said combining step includes the step of mixing boric acid as the delayed-action heat-triggered neutralizer.

12. The process of producing a light-weight aggregate as claimed in claim 8, wherein the combining step includes the step of mixing Portland cement as the expander controller material in an amount commensurate with the desired bulk density of the light-weight aggregate.

13. The process of producing a light-weight particle material suitable for use in building, construction, building products, insulation, and the like, comprising the steps of introducing into a mixing zone liquid sodium silicate and anhydrous sodium silicate, the sodium silicate solids being present in an amount between 50 and 56 percent by weight, introducing into said mixing zone a delayed-action, heat-triggered neutralizer material in the form of granular boric acid in an amount constituting between about 5 and about 25 percent by weight of the sodium silicate solids in said mixing zone, and also introducing into said mixing zone an expansion controller material in the form of Portland cement in an amount constituting between about 8 percent and about 25 percent by weight of the sodium silicate solids, providing a vigorous mixing action in said mixing zone in the presence of heat to mix the contents thereof into a homogeneous mass, the heat being sufficient to produce in the mass a temperature below the boiling point of water but sufficiently high to dissolve the anhydrous sodium silicate therein, removing the mass from the mixing zone, cooling the mass into a friable and crushable state, crushing the cooled mass into small particles, heating the particles to pre-expand and dry the surfaces of the particles such that their surfaces are stabilized to be capable of being stored together for weeks, if desired, without coalescing between stored particles, and subsequently heating the stabilized particles to a temperature in the range from about 880* F. to about 1,020* F. to produce the desired expansion thereof.
