摘要： A system and method for introducing a slurry mixture for making gypsum board is disclosed. The system includes a mixer for mixing slurry and directing it to an exit gate, a foam injector for injecting foam into the slurry, and a canister connected to the mixer for inducing swirl to the slurry. The system also includes an elongated hose and an optional adapter for depositing the slurry onto paper to form the board. Ends of the elongated hose are coupled to the canister and to the inlet of the adapter. Slurry is directed from the canister, through the hose, and into the adapter for exiting its outlet. Optionally, a mixing boot and/or elbow joints may be included. Use of the hose and adapter enhances the flexibility of the system, including moving the mixer offline or adjacent to the paper or belt, and improves foam blending in the slurry mixture.

摘要： Sulfate and sulfonate derivatives of unsaturated fatty alcohols, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol composition is made by reducing a metathesis-derived monounsaturated alkyl ester. The fatty alcohol composition is then converted to a sulfate or sulfonate derivative by one or more of alkoxylation, sulfation, sulfonation, and sulfitation. Of particular interest are the sulfate and ether sulfate derivatives. Microscopy studies indicate that the unsaturated sodium sulfates in particular have a lamellar phase that should enable formulation at high actives levels. Sulfate compositions comprising 40 to 60 wt. % of a monounsaturated fatty primary alcohol sulfate and 40 to 60 wt. % of a secondary hydroxyalkyl primary alcohol sulfate are also disclosed. The derivatives and sulfate compositions are valuable for many end-use applications, including, for example, agricultural dispersants, water-soluble herbicides, anionic emulsifiers for agricultural use, hard surface cleaners, light-duty liquid detergents, personal cleansers, gas well foamers for oilfield applications, laundry detergents, enhanced oil recovery compositions, latex paints, and specialty foams.

摘要： Particulate high-emissivity (high-ε) refractory products include a mixture of (a) a particulate refractory base material which includes at least one particulate binder material, at least one particulate refractory raw material filler material and optionally at least one refractory additive; and (b) a high-ε pigment in an amount sufficient to impart high-ε properties to the refractory product when cured of at least 0.80. The high-ε pigment is homogenously dispersed throughout the particulate refractory base material and is thereby less susceptible to loss of high-ε properties over time. The particulate high-ε products may be formed into an castable wet mix, an aqueous slurry or an insulating aqueous foam and cured so as to provide a component part of a high temperature refractory structure (e.g., the walls or ceiling of a refractory furnace) having high-ε properties.

摘要： A method of producing a carbonated composite material includes: providing a carbonatable cementitious material in particulate form; mixing the carbonatable cementitious material with water to produce a mix; forming a predetermined shape with the mix, wherein the predetermined shape has an initial pore structure containing an initial pore solution having a first pH; pre-conditioning the predetermined shape to remove a predetermined amount of the water from the predetermined shape to produce a pre-conditioned shape; carbonating the pre-conditioned shape in an environment comprising carbon dioxide to produce a modified pore structure containing a modified pore solution having and a second pH, wherein the difference between the first pH and the second pH is represented by a ΔpH, and the ΔpH is 1.0 or less.

摘要： The main weaknesses of masonry buildings, especially those made of clay, against earthquakes are: high weight, which increases the earthquake force that is proportional to the weight; low resistance that causes an early crushing of walls and ceilings; lack of ductility, which causes the masonry buildings to collapse immediately after cracking. These weaknesses have been the main causes of collapse of masonry buildings in past earthquakes in various parts of the world. Also, many of the restoration works, done on the historical monuments that were made by the mentioned materials, showed their inadequacy in some recent earthquakes This invention improves clay, as an eco-friendly, low-cost material with high workability, to present a better seismic behavior, by decreasing its specific weight to less than tones/m3 and increasing its tensile resistance up to five times of the ordinary clay, and giving better insulation capabilities against heat, sound and moisture to it.
