| 110 | Method for recycling a paint recovery effluent | US240439 | 1994-05-10 | US5492626A | 1996-02-20 | Kazuo Uenoyama; Tetsuro Kajino; Toshihiro Okai; Takayuki Shibata; Toshiya Koike |
| The object of the present invention is reuse of the filtrate of a paint mist-cleaning water mixture as cleaning water without reduction in concentration efficiency. According to the present invention, a waste paint-cleaning water mixture 2 available on trapping a water-based paint mist in cleaning water 1 is concentrated to recover the paint and the aqueous phase is recycled as cleaning water. In this system, the cleaning water prepared by reusing the aqueous phase is adjusted to an acid value of not greater than 10 and a pH value of 7.0 to 9.0. Controlling the amount of low molecular acid components in the aqueous phase in this manner prevents an abnormal viscosity increase in the filtration-concentration of the waste paint-cleaning water mixture. | ||||||

| Method for removing and reclaiming excess uncured paint from a paint spray booth includes entraining uncured over-sprayed paint particles in a stream of air passing through the paint spray booth. The entrained over-sprayed paint particles are then caused to come into contact with a flowing aqueous flood sheet within the paint spray booth such that a substantial portion of said paint particles are solubilized within the flowing aqueous flood sheet and thereby removed from the stream of air. The flowing flood sheet includes (i) between about 10 to 45 percent by weight of an N-methyl pyrrolidone, (ii) between about 15 to about 40 percent by weight of at least one alkyl glycol ether having 1 to 4 carbon atoms in its alkyl moiety; and (iii) about 0.1 to about 2.0 percent by weight of a non-ionic linear alcohol ethoxylate surfactant sufficient to reduce the flood sheet vapor pressure. The solubilized uncured paint particles are thereafter separated and collected from the aqueous flood sheet so as to thereby be reclaimed for future use. | ||||||

| 115 | Method of making a filler from automotive paint sludge, filler, and sealant containing a filler | US763324 | 1991-09-20 | US5160628A | 1992-11-03 | Michael J. Gerace; Janet M. Gerace |
| A method for making a filler from automotive paint sludge is provided. Paint sludge containing water, solvent and uncured polymer resin is treated by removing a first portion of the water by mechanically drying the sludge to produce a concentrated sludge, and a second portion of the water is removed by treating the sludge with a chemical drying agent to produce a dried powder. Alternatively, the second portion of the water may be removed by agitating the concentrated sludge under a vacuum to produce a dehydrated putty. The resulting dried powder or putty can then be used as a filler in sealants and other products. | ||||||

| Disclosed is a method for recovering acrylic resin from an excess of a sprayed powder coating composition. An excess of the powder coating composition which is not deposited onto an article to be coated and is recovered in a coating apparatus is dissolved in an aromatic hydrocarbon solvent which dissolves the acrylic resin component and which has a solubility of a curing agent of not more than 1.0 g (curing agent)/100 g (solvent) at 20.degree. C. and the acrylic resin component is recovered from the resin solution. The acrylic resin component thus recovered can be reused as a resin component for coating compositions. | ||||||

| A process is disclosed for converting a bis-(diol) terephthalate to dimethyl terephthalate, by interchange in a methanol medium in the presence of magnesium methylate as catalyst. In this way dimethyl terephthalate may be regenerated from scrap of polyterephthalate or copolyterephthalate filaments or films, for the purpose of manufacturing fresh polyterephthalates or copolyterephthalates which can then be used for the manufacture of, for example, filaments or films. | ||||||
| 119 | Phenolic resin recovery process | US864350 | 1977-12-27 | US4118346A | 1978-10-03 | Robert Milton Summers |
| A method of recovering a resin material from an infusible phenolic plastic composition. The infusible phenolic plastic composition is ground to a powder and mixed with an alkali solution to produce a liquid mixture. The liquid mixture is heated to a temperature selected between 260.degree.-340.degree. C and maintained at this temperature between 160 and 3 minutes causing the resin in the infusible phenolic plastic composition to dissolve in the alkali solution and produce a liquor. Thereafter the liquor is passed through a filter to remove any insoluble plastic composition therefrom. An acid solution when added to the filtered liquor causes a solid to precipitate from the liquor. The solid is separated from the liquor and washed in a water bath to remove any water soluble salts, phenols, and cresols from the recovered resin material. | ||||||
