Abstract

PURPOSE:To retrench steam or other heat sources which have been required for heating a chemical converting liquid or the like in a conventional pretreating step, by obtaining a heat source for said pretreating step from a cooling load in the step of electrodeposition coating using a heat pump. CONSTITUTION:After a workpiece to be coated being treated in the step A-I of pretreatment is electrodeposition coated by dipping it in an electrodeposition tank 6 held at about 25-35 deg.C in the step of electrodeposition coating, it is spray washed in each washing step K, L, M. Thereafter, it is washed in a washing step N by completely dipping it in a water tank 9 and further washed with fresh water in a washing step O. Thus, the electrodeposition coating is finished. Hereon, the heating of a chemical converting liquid in a tank 3 for a chemical converting liquid and temp. control are performed using a heat pump 17 obtd. by a cooling load in the step J of electrodeposition coating. That is, the chemical converting liquid in the tank 3 is supplied P to the first heat exchanger 10, heated therein and then returned to the tank 3. Thereafter, a heating medium in the exchanger 10 is supplied P to the condenser 18 of the pump 17, heated with a cooling medium such as freon supplied from a compressor 20 and then circulated to the exchanger 10.

The present invention relates to a method of painting electrical tags, and particularly to a method of electrodeposition, which uses less energy. The electrodeposition coating method is a method in which water-based paint is placed in water and the paint molecules are positively or negatively charged to avoid electrophoresis and deposit the paint on the object to be coated. , 151
Since the coating film produced by this method has excellent corrosion resistance, it is widely used for coating various industrial products such as automobile bodies and parts of automatic IT, electric refrigerators, and electric washing machines. Electrodeposition φ) techniques include an anion type and a cation type, but in any case, as shown in Fig. Place the product (as shown) in a preliminary DQ fat factory and spray it with an alkaline degreaser.

After ti4iC electrodeposition is applied by dipping into the electrodeposition tank 6 kept at a liquid temperature of approximately 25 to 35°C in the electrocoating process, the culm of the sixth washing machine is coated with the seventh washing process and the eighth washing process. = [In culm M, spray cleaning is carried out respectively. 6th to 8th water washing, TP
The washing water used in steps 7 to M is the coating solution 11 discharged from the electric tank 6 through the conduit 7, which is passed through the ultrafiltration device 8 at 45.
The filtered water is ultrafiltered and subjected to Cr1, and the process is repeated sequentially from the later water washing L culm M to the earlier water washing 1 culm K.
On the other hand, the condensate is circulated through the conduit 16 to the electrodeposition tank 0. Then, in the ninth water wash I Pi! The chemical solution is heated and temperature controlled in the second step.
As shown in the figure, electrodeposition coating is carried out using a heat pump 17 obtained by a cooling load of 1. The heating medium is sent to the first heat exchanger 10 (after being heated, it is returned to the chemical liquid 4fli3), and then the heating medium is transferred to the first heat exchanger 10 by the heat pump 17. It is heated by the refrigerant gas such as Freon, R-12, etc. sent from the refrigerator 20, and then circulated to the heat exchanger 10 of ri!1. The refrigerant gas heats the heating medium in the condenser 18, and is condensed by itself through the expansion valve 21 to the evaporator 19.
