What Are the Requirements for Machine Coating? How to Maintain Machinery When Seasons Change?

Image
What coating requirements are required for machine coating? 1. Film thickness. Painted products generally require a certain thickness of coating film, which requires spraying several times. 2. Hardness. The important point of the coating film is that it must have high hardness to prevent collision and friction. Generally speaking, the hardness of baking paint is higher than that of self-drying paint, so the baking process should be used as much as possible in the design. 3. Adhesion. Coating adhesion is an important indicator of mechanical strength. The key to adhesion is pretreatment, and a reliable pretreatment process is shot peening. Therefore, the structural parts are generally shot blasted. 4. Weather resistance. Painting machinery and equipment generally works in an outdoor environment, so it is necessary to use paint with good weather resistance. 5. Luster. The gloss of the coating depends on the degree of atomization of the spraying equipment. The finer the atomization,...

Fire and Explosion Protection Measures for Paint Production Line

Image
During the operation of the painting production line, due to the majority of the employees have limited knowledge of the workplace safety of coating, gas, natural gas, it has directly caused the fire, explosion and other safety accidents occurring on-site from time to time which not only make the firm itself face economic losses, but also bring significant health hazards to the employees, and even at a life-threatened level. For this reason, fire prevention and explosion-proof measures for painting production line can't be delayed! 1. Smoking and carrying lighters, matches and other inflammable materials are prohibited in the painting construction site. 2. When the coating workshop needs hot fire maintenance welding, it is necessary to first go through the fire consent procedures, agree to suspend coating operations. Before using fire, anything inflammable should be cleaned in 30 meters of the worksite within the paint scale; paint bucket, paint tank should be sealed, the conce...

Water Saving Technology of Painting Production Line

Image
With the development of industrial technology, coating lines are used in many fields for their high efficiency, economical safety, low pollution, and fully automated management. How to save water has become a significant issue for painting production line. Water saving technology of painting production line includes: 1. Reverse process overflow water cleaning After degreasing or phosphating, multiple water rinses are required to clean the chemicals adhering to the workpiece surface. In order to save water, each washing process before the coating line is designed into two water-saving units, so that the cleaning water is discharged from each process tank separately into a unit, and use the back section of the washing water supply, followed by the front section of the washing tank overflow water supply, finally discharged to the gutter to improve the utilisation rate of cleaning water. Among the industrial designs of some paint production lines, degreasing and phosphating use their ...

Components of Paint Production Line

Image
The seven main components of the paint production line include pre-processing equipment, powder-coating system, painting equipment, oven, heat source system, electronic control system and suspended conveyor chain. 1. Pre-processing equipment Spraying multi-station pre-processing unit is a standard equipment for surface processing, the principle of which is to use mechanical flushing to accelerate the chemical reaction to complete the process of degreasing, phosphating, washing and other functions. Pre-processing can also use the shot blasting machine which is suitable for simple structure, severe corrosion, no oil or less oil steel parts, and no water pollution. 2. Powder-coating system The mini air fan + filter element recovery unit for powder coating is the more advanced and faster powder recovery unit with fast colour change. It is recommended to use products with good performance for the critical part of the powder-coating system. 3. Painting equipment Such as oil spray pain...

Advantages of Painting Machinery and Equipment

Image
Nowadays, machine coating is becoming more and more popular. Following is the introduction of the advantages of painting machinery and equipment. 1. The automatic spray coating machine is driven by a motor when spraying. There is absolutely no speed imbalance situation (otherwise the machine will break down). Crisscross spraying is the spray gun that can spray from the four sides one by one at a certain angle, so even uneven areas can be sprayed. Besides, it is definitely more uniform than manual spraying as long as the paint supply is stable. 2. It causes little harm to the workers' body. The workers do not need to be next to the machine when it is spraying, the product can be taken out after finishing spray. 3. It has high efficiency and high yield. The automatic coating machine is mechanical automatic walking, the same product only needs to be programmed once. It keeps spraying and will not change, which eliminates the instability of manual spray. The high speed of the mach...

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 by wat...
