The company's research achievement "infrared electromagnetic wave heating device" has successfully obtained many national invention patents and utility model patents. The patented product is specially developed to transform the traditional fuel car painting room and change the current situation of high energy consumption and high emission. After the actual use and market inspection by Shanghai Volkswagen and many auto repair enterprises, the product performance, quality and cost performance have been widely recognized. What is more gratifying is that it has been widely praised by front-line painting technicians! After the transformation, it fully meets the requirements of urban energy conservation and emission reduction, effectively reducing the daily and monthly production costs of auto repair enterprises and improving their competitiveness. The comparison shows that:
1, saving liquidity. Diesel oil should be paid before use, and electricity should be paid after use;
2. Save warehouse space. Diesel oil (waste engine oil) should be stored in a special place, which not only occupies space, but also has potential safety hazards, and electricity consumption can be controlled with only one key;
3. It is easier to control the production cost. Diesel oil is in short supply, (the cost of enterprise development and environmental protection paid by waste engine oil heating will be higher). The price is greatly affected by the international oil price, and the cost is difficult to control, but the electricity consumption is not worried;
4. The daily maintenance cost is reduced. Diesel combustion system, fan, filter cotton, etc. in spray booth. It needs frequent maintenance and replacement, and the annual maintenance cost is about 4,000 yuan. However, the heating and drying system of the spray booth with "infrared electromagnetic wave multi-band heating device" has almost no wearing parts, and there is basically no maintenance cost within five years.
5, not affected by seasonal environmental temperature. In winter, the external environment temperature is low, and the diesel oil temperature rises for a long time, so the cost is higher than that in spring, autumn and summer 1/3. After the transformation of "infrared electromagnetic wave multi-band heating device", the efficiency is improved more obviously.
6. Rapid heating: the heating speed is 2-4 times that of ordinary metal or timely electric heating tube. Electricity-heat conversion efficiency is over 95%, saving energy and reducing emission, and reducing the operating cost of enterprises. Stable electrical performance, no instantaneous current impact, no damage to the circuit. Effectively improve the directional electromagnetic heat radiation and make the infrared energy more concentrated; The service life is more than 30,000 hours, which is environmentally friendly, pollution-free, noise-free, electromagnetic radiation-free, and there is no hidden danger of occupational diseases of front-line painting technicians.
Working principle and technical characteristics of infrared electromagnetic wave heating device
1, working principle
A new generation of infrared electromagnetic wave heating baking paint device adopts an "infrared blackbody radiation electromagnetic heat pipe" containing noble metal oxide and nanometer refinement (no light heater, no heat loss caused by the conversion of light energy into heat energy), and adopts a parabolic stainless steel nano-layer heat energy efficient reflector; Combined into a standardized combination box, after connecting the position angle regulator and the distribution controller, it can be used alone or in combination as needed. The radiant energy of infrared electromagnetic wave is used as the heat source, and the infrared electromagnetic wave generated by special electrothermal materials is used to increase the paint temperature through radiant heat transfer, so as to achieve the purpose of uniform and rapid drying of paint in an energy-saving and efficient way. In this electrothermal energy conversion process, the electrothermal energy loss is very small (
2. Table of technical characteristics
(1) energy saving
Due to the directional radiation heating of infrared electromagnetic waves, energy is transmitted by electromagnetic waves, and no energy-consuming medium is needed, and the radiation energy of infrared electromagnetic waves directly acts on the materials to be dried, and the electrothermal conversion efficiency is above 95%. This patented product only needs to turn on all radiators when baking the whole car, and only needs to turn on a small number of radiators when baking the local paint of most cars, and the baking temperature can meet the set requirements in a short time. Compared with the traditional fuel spray booth, the energy-saving effect is more remarkable.
(2) Environmental protection
During the heating process, the product does not emit any harmful gases or light pollutants, does not cause occupational injury to painting technicians who have been working in the painting room for a long time, does not consume oxygen and moisture in the air, and has no noise.
(3) The paint surface has good quality and high efficiency.
The heating and drying of paint surface is a process of infrared electromagnetic heat radiation infiltration. The heat is directly conducted to the inner layer of the paint, so that the solvent, diluent and curing agent in the paint are volatilized first, and then dried and solidified from the inner layer, so there will be no bubbles and cracks on the surface of the paint. After baking, the quality of paint surface is good, the grey spots are reduced by 80%, the smoothness is high, the polishing process and material consumption can be greatly saved, the gloss loss phenomenon is reduced by 85%, and the paint layer is bright and hard. It can be polished and cleaned immediately after drying, which improves the working efficiency.
