Process for continuous production of water-absorbent resin product

There is disclosed a process for continuous production of a water-absorbent resin product by which the water-absorbent resin product having high properties can continuously be produced easily and inexpensively with stable constant quality. In addition, there is disclosed a water-absorbent resin product having high properties and being stable in quality. The process comprises the following steps of: (A) measuring a water-absorbent resin by its predetermined property and/or its predetermined component content, wherein the water-absorbent resin comes being continuously produced via a classification step and/or a surface-modifying step; (B) separating a predetermined amount of water-absorbent resin (a) from the water-absorbent resin that comes being continuously produced, wherein the water-absorbent resin (a) is a water-absorbent resin which displays not less than a definite value and/or a water-absorbent resin which displays not more than a definite value as to the predetermined property and/or the predetermined component content in accordance with results of the aforementioned measurement; and (C) mixing at least a portion of the aforementioned separated predetermined amount of water-absorbent resin (a) into a water-absorbent resin that comes being continuously produced via a classification step and/or a surface-modifying step on the same or another production line.

Aquosity bi-component polyurethane coloured paint and method of manufacturing the same

The invention discloses a two-component waterborne polyurethane colored paint and the preparation method. The components of the paint are 5 to 15 water, 0.2 to 0.5 dispersant, 0.1 to 0.3 antifoamer, 0.1 to 0.3 wetting agent, 3 to 25 paints, 0 to 50 fillers, 10 to 80 film forming resins, 0 to 5 film forming additives, 0.1 to 0.3 disinfectant, 0.1 to 0.3 antiflash rust agent, 0.5 to 2 thickeners, 1 to 20 hydrophilically-modified polyisocyanate. The preparation method is that water, dispersant, antifoamer, wetting agent, paints and fillers are dispersed evenly by a sand mill, a ball mill or a high-speed stirrer after stirring, and are added with film forming resins, film forming additives, disinfectant, antiflash rust agent and thickeners to gain the product-component A. The hydrophilically-modified polyisocyanate is component B. The component A and component B are mixed uniformly when using. The invention is characterized in that the invention does not adopt organic solvents, does not contain toxic paints and has no harm on the human body and environment, and the properties can reach the solvent two-component polyurethane paint, which can be produced to the primer, intermediate coat and finishing coat, and can be applied in the surface of the wooden ware, cement and metals.
