    摘要： A composition and method of treating paint spray booth water to detackify organic solvent based paint particles. The composition comprises a melamine polymer obtained from the reaction of melamine, aldehyde and an amine selected from the group consisting of dicyandiamide and glycine. These melamine polymers may be used in combination with a polyacrylamide, which combination exhibits surprising and unexpected effects when used to detackify organic solvent paint particles.

    摘要： The present invention relates to a novel method for coagulating waterborne paints in paint spray booth recirculating water. The coagulant aid comprises a polynucleate hydroxy silicate-sulphate compound (hereinafter PASS) having the following average composition of the general formula:Al(OH).sub.B (SO.sub.4).sub.C (SiO.sub.X).sub.D (H.sub.2 O).sub.Ewherein B ranges from 0.75 to 2.0; C ranges from 0.30 to 1.12; D ranges from 0.005 to 0.1; X is greater than 2.0 but less or equal to 4.0 such that3=B+2C+2D(X-2)E is 1.5 to 4 when the product is in solid form; and E is larger than 4 when the product is in aqueous form, which may optionally be used together with alum or a mixture of alum and a polyamine. The coagulant aids of this invention may also be used advantageously with detackifying agents to simultaneously detackify and coagulate solvent based paint particles.

    摘要： A method of detecting defects in nuclear fuel within a fuel rod that first heats the fuel rod to a temperature substantially above the ambient temperature. The surface temperature of the fuel rod cladding is then monitored as the fuel rod is allowed to cool. Variations in the temperature measured over the surface is then noted as an indication of defects.

    摘要： A method of removing layers of heat cured paint buildup on supporting hangers is disclosed. The method includes coating support hangers with a layer of a thermally expandable material in a water soluble carrier and thereafter applying a water insoluble coating layer. The thermally expandable material, the carrier and the water insoluble coating are all selected so as to be relatively unaffected by the curing temperatures of the paint line where the hangers are to be used. When an undesirably thick coating of cured paint has built-up on the hangers, it is removed by heating to a temperature sufficient to expand the thermally expandable material thereby cracking the paint layers. Thereafter, the hangers are soaked in a hot aqueous solution to dissolve the carrier layer and remove the cracked, cured paint layers.
