Introduction to Water Curtain Spray Booth and Water Wash Paint Booth

Image
  Details about Water Curtain Spray Booth The water curtain spray booth uses a flowing curtain-like water layer to collect and take away paint mist. The curtain-like water layer is generally set directly in front of the air stream containing paint mist. In the painting room with horizontal air supply, the water curtain hangs like a curtain on the wall directly in front of the operator. The water curtain in the large up and down air suction painting room is arranged at the bottom of the room, and placed on the slope. When the air flow is rushing to the water curtain, the paint particles impact the water drop and are left behind. The curtain is maintained by the special circulating water pump, and the water volume is adjusted by the regulating valve to control the integrity of the water curtain shape. The wall of the water curtain spray booth is not easy to be polluted, the effect of treating paint mist is better, and the structure is simple. However, as the paint mist is collected b...

Quality Control and Optimization of Automobile Painting and Coating

Image
  Over the years, with all the progress in the field of automobile design and manufacturing, there has always been an unchanging factor, that is, the beauty of the car is the key factor determining the consumer's purchase decision. In the purchase process, the consistency, quality, and diversity of vehicle paint play a crucial role. Modern consumers can use the car paint to spray a variety of colors. In the automotive industry, which is more competitive than ever, the process control technology to ensure and improve quality directly affects profitability as well as market share.   Automobile coatings and the processes used to coat automobile surfaces use advanced technology and are carried out in professional automotive paint spray booth. It can produce a durable surface, high-quality appearance while maximizing efficiency and complying with environmental regulations. The quantity and quality of the painting production line   have a significant impact on manufacturing cos...

Explanation of the Advantages and Disadvantages of Powder Coating Equipment

Image
  Powder coating equipment manufacturers need to deeply understand the advantages and disadvantages of powder coating equipment in production, so as to better carry out production.   Advantages of Powder Coating Equipment:   1. The powder coating does not contain organic solvent, which can avoid fire, poisoning and unsafe transportation problems caused by organic solvent. Although there is a danger of dust explosion, the explosion can be completely avoided as long as the dust concentration in the system is properly controlled.   2. The powder coating is a 100% solid system, which can be used in closed-circuit circulation system. The over sprayed powder coating can be recycled and reused, and the utilization rate of the coating can reach more than 95%.   3. When powder coating is applied, the thickness of coating film can be controlled, and the thickness can reach 30-500 μ m at one time. It is equivalent to the thickness of several to more than ten coats of solve...

The Characteristics of Container Automatic Painting Process

Image
  The container is a steel structure with a relatively regular shape. The variety of matching coatings is single, and the manufacturing process is a mass assembly line operation. Therefore, it is inevitable to realize the mechanization and automation of the container coating process. Nowadays, container coating has gradually realized the automatic painting of epoxy zinc-rich primer, epoxy middle coat and epoxy inner top coat. Automatic painting has the following advantages:   (1) Automatic painting can ensure the quality of the coating film. Painting work in the shipping container spray booth is a heavy manual labor. Painting workers have been in a polluted and flammable environment for a long time, no matter how skilled the operation is, the quality of the coating film will always be affected by factors such as fatigue, health, and personnel transfer. However, automatic painting can avoid the above shortcomings. At the same time, under the condition of automatic paint sprayin...

Collection and Purification of Cabinet Spray Booth Exhaust Gas

Image
  1. Waste Gas Purification Tower of Cabinet Spray Booth Working principle of activated carbon adsorption tower: organic gas or particulate matter in workshop is collected by gas collecting hood, and organic gas is transported into activated carbon tower by pipeline. When the organic gas enters the waste gas purification tower of the cabinet spray booth , the wind speed will drop down, and the large particles in the gas will naturally settle into the bottom of the tower. The part of the organic gas dissolved in the gas flows into the activated carbon filter layer along with the gas flow. When organic gas enters the carbon layer, the organic gas is absorbed into the carbon by the activated carbon. The dried-up air passes through the carbon layer and enters the gas outlet, and the gas is discharged into the atmosphere after mechanical self-absorption. In the adsorption process of the activated carbon layer, the carbon will have a saturated period of time. The length of the activated ...

Industrial Painting - Introduction to the Paint Booth

Image
  There are many types of paint booths. Except for a few small-scale painting units that still use intermittent spraying outdoors, the larger-scale paintings all use the paint booths operated continuously by industrial paint booth manufacturers. In addition, the paint booth is increasingly combined with pre-treatment equipment, coating drying equipment, and conveying machinery to form a highly automated painting line.   Different types of paint booths according to different ways   All paint booths are equipped with an air supply and exhaust system. According to the air supply and airflow direction, the paint booth can be divided into four types: horizontal air extraction, longitudinal air extraction, bottom air extraction, and upper air supply and bottom air extraction.   According to the treatment methods of paint mist, the types of paint booth   can be divided into dry type and wet type.   Difference between dry type and wet type   The dry spray boot...

How to Wire the Motorized Hoist Correctly?

Image
  Motorized Hoist is a kind of light and small lifting equipment. Most motorized hoists can be followed and manipulated on the ground by people using buttons. It can also be manipulated in the driver's cab, or it can be controlled remotely by wire (wireless). Motorized hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. It has the characteristics of small size, light weight, simple operation, and convenient use. It is used in industrial and mining enterprises, storage docks and other places.   The lifting weight is generally 0.1 to 80 tons, and the lifting height is 3 to 30 meters. Motorized hoist is composed of motor, transmission mechanism and drum or sprocket, which can be divided into wire rope motorized hoist and ring chain motorized hoist. According to the electric hoist manufacturer, the wire rope motorized hoist is divided into CD1 (single speed lifting) and MD1 (double speed lifting); micro motorized hoist, winch and multi-f...

Painting system installation conditions and environment

Image
  The spray booth has the function of temperature and humidity control, the temperature is 20 ° C +5 ° C, the relative humidity is 30% ~ 80%, and the temperature and humidity can be adjusted arbitrarily in the four seasons.   The humidity can be adjusted to 30% ~ 50% in spring and summer, and it can be adjusted to >70% in autumn and winter, and the environment needs to reach the set temperature and humidity level within 30 minutes of operation of the automatic painting equipment.   The cleanliness of the air in the painting room is not less than 100,000, the noise in the spraying area is not more than 75 decibels, and the illuminance is ≥ 650lux. The top of the spray chamber   needs to be equipped with a dynamic pressure chamber and static pressure.   The chamber is made of 1.5mm galvanized steel sheet. The air-conditioning air sent by the air supply system enters the dynamic pressure chamber, and passes through the deflector, multi-element regulating valve (...
