Definitions
- the present invention relates to the use of finely dispersed in water fatty acids as Entklebungsmittel in the industrial deposition of dispersed solids, in particular in the wet leaching of paint overspray in spray booths dispersed in circulating water paint particles from an aqueous carrier medium, in particular circulating water of a spray booth with Wet scrubbing represents.
- the degumming agent based on fatty acids can be used completely free of corrosive anions and requires that an energetic utilization of the paint coagulate removed from the circulating water can be operated economically.
- paint overspray The portion of the paint which does not deposit on the components as desired and must be removed from the circulating air is called paint overspray.
- the paint overspray is for separation from the circulating air in a liquid carrier medium, usually water, introduced and removed after detackifying and coagulation of the particulate paint constituents from the carrier medium and further utilized.
- a liquid carrier medium usually water
- System basin into which the carrier medium enriched with the paint overspray is transferred.
- the discharge of the coagulum from the carrier medium takes place continuously in the system basin and with suitable discharge devices and / or separators.
- the coagulum depleted carrier medium is also continuously, for example as circulating water, in the
- the wet scrubbing of the paint overspray in the paint booth is often due to the turbulent mixing of circulating water (carrier medium) and the aerosol of the "overspray" by means of a venturi opening in the recirculation air duct of the paint booth, creating an air-water Mixture containing the coarse and / or finely dispersed paint particles, which has a lowered compared to the circulating water in the system basin density.
- the supply of the air-water mixture for coagulation and physical separation into the system basin with a given volume flow thus has the consequence that this air-water mixture moves upwards at the inlet point of the system basin due to the lower density, so that flotation plants for the separation Of paint coagulum are often preferred.
- the paint overspray is removed by means of a water curtain from the spray booth and transferred to a sedative basin for sedimentation. Regardless of the method of separation, decoating the paint particles to form a coagulum that can be carried out is necessary for effective deposition of the paint overspray.
- the detackifying agents used are, by default, polyvalent metal cations, for example magnesium, calcium, iron, zinc and / or aluminum ions. These uploaded positive cations cause the detacking and flocculation process of the paint particles. Since the metal cations are continuously removed with the Lackkoagulat from the circulating water, the Entklebungsstoff must be continuously replenished in the circulating water.
- the anions introduced with the polyvalent metal salt are enriched in the circulating water. Accordingly, highly concentrated metal salt solutions are preferred from an application point of view, which contain neither halide anions (metal corrosion) nor sulfate anions (concrete corrosion) in order to prevent corrosive processes on system parts of the circulating bath.
- highly concentrated metal salt solutions are preferred from an application point of view, which contain neither halide anions (metal corrosion) nor sulfate anions (concrete corrosion) in order to prevent corrosive processes on system parts of the circulating bath.
- phosphate- and nitrate-containing salts should be avoided for reasons of environmental compatibility and increased costs in accordance with legal guidelines for wastewater discharge.
- EP 1865033 proposes to avoid the accumulation of corrosive anions in paint coagulation as detackifying a concentrated aqueous solution of
- Alumiumcarboxylat salts wherein as the carboxylate anion, the anion of a
- Hydroxymonocarboxylic acid is present and the solution contains at least two equivalents of hydroxymonocarboxylic acid per mole of aluminum.
- an aqueous solution of aluminum lactate for paint coagulation is particularly preferred.
- EP 1937601 discloses the use of concentrated aqueous solutions of protonated polyalkyleneimines as decoating agents for paint coagulation in the wet scrubbing of a paint shop.
- halide ions are first of all replaced from the polymer concentrate or detackifying agent by hydroxide ions in a complicated membrane process, after which, by renewed acidification of the solution, anions such as sulfate ions, phosphate ions, Borations, nitrate ions and anions of organic acids are introduced into the decoating agent.
- the detackification of the paint overspray is further supported by the additional dosage of polyvalent metal, so that the addition of metal cations selected from magnesium, calcium and / or aluminum ions to the polymer concentrate according to the teaching EP 1937601 is particularly preferred.
- Entklebungsmittel teach US 4,888,386 and US 5,068,279, which is particularly focused on ways to reduce the free formaldehyde content, the partial release, however, is inherently associated with the use of this polymer class, so that a sustained commercialization of such Entklebungsstoff technically not in prospect can be.
