摘要:
An electrodeposition process using an aqueous coating composition comprising a carbamate-functional crosslinking agent and at least one principal resin is described. The carbamate-functional crosslinker is formed by first reacting a polyamine having at least two primary amine groups and at least one secondary amine group with a cyclic carbonate, and then reacting the product of the first reaction with a polyepoxide compound.
摘要:
The invention relates to a novel electrocoating composition for metallic substrates that exhibits "thick-build" protective properties at "medium-build" thicknesses. It is composed of a self-addition epoxy resin-polyamine adduct, a blocked isocyanate cross-linker, a polyglycol-polyamine grind resin, a plasticizer, an anti-cratering agent and pigments.
摘要:
A rack for supportively mounting a solar collector to a mounting surface to set the angle of tilt with respect to the sun. One end of the rack is adapted to provide predominant support of the collector, while the other end is height adjustable to provide the proper angle and to accept tension and/or compression due to wind leading.
摘要:
The present invention relates to a thermoset powder coating composition and method of application. The coating includes a copolymer having a reactive functionality selected from the group consisting of epoxy, carboxy, and hydroxy functionalities and mixtures thereof, a suitable crosslinking agent capable of reaction with the reactive functionality on the copolymer, and an aliphatic or aromatic crystalline, hydroxyl containing compound having a melting point of between 30.degree. C. and 150.degree. C. and a flow control agent. The powder coating is a pigmented or clear coat powder composition applied over a primer layer.
摘要:
A cup-shaped member having cylindrical sides for coupling adjacent ends of headers of solar collectors of the liquid heat-exchange type, or a header to an associated manifold. The member has a cylindrical body and an orifice in the base through which liquid flows. Several arrangements for using the member to couple the headers together or to a manifold are disclosed.
摘要:
A method for producing hydrogen from a light hydrocarbon gas with the hydrocarbon gas being converted to particulate carbon and hydrogen and thereafter quenched with liquid sulfur with the purified hydrogen being recovered as a product.

摘要:
A method for producing sulfur and energy from an acid gas stream containing hydrogen sulfide by partially combusting the acid gas stream to produce a combustion product gas, mixing a sulfur dioxide stream with the combustion product gas, separating sulfur from the mixture, combusting sulfur to produce sulfur dioxide and heat energy and passing at least a portion of the sulfur dioxide to the combustion product gas.
