(Summary description)In the coating production process, a large number of powder and granular materials need to be used, and there are many kinds and complex characteristics. Therefore, the pneumatic conveying technology is very suitable for the application of the coating industry. But at the same time, powder and granular materials with different characteristics also put forward higher requirements for pneumatic conveying technology.   1. Automatic feeding system The powders and granules used in the coatings industry are mainly divided into two categories: pigments and fillers. Most of the raw materials are packaged in the form of ton bags or small packages of 25 kg. Most of the traditional manual production methods use manual packaging, manual unpacking, and manual feeding. Not only the labor intensity of personnel is extremely high, but also the dust is serious, causing pollution to the working environment and harming the work environment. The physical and mental health and safety of the staff. With the country's emphasis on environmental protection and the strengthening of public awareness of environmental protection and health, traditional production methods have been gradually abandoned, and automatic feeding systems have gradually been favored by paint manufacturers. The automatic feeding equipment such as the big bag unpacking station and the small bag unpacking station provided by Honggong can be closed and feeding, reducing the dust in the workshop and reducing the labor intensity of personnel, which can easily solve the feeding problem of large bags and 25 kg small bags.   2. Small material batching system The pneumatic conveying design of the coating industry should be customized according to different requirements such as the characteristics of the conveyed materials, the size of the production capacity, the structure of the plant, and the requirements of the production process. In the face of small batch and multi-variety products, such as color paste production line, it is suitable to use the small material batching system. The small material batching system provided by Honggong can be used for batching of various powders and granules, and can meet the raw material batching of powders or granules of various varieties, small batches and high precision requirements, and reduce the damage caused by mistakes and wrong operations. product quality problem. 3. Mass pneumatic conveying system In the coatings industry, there are also coating production lines with high solid content and large batches, which are also suitable for the use of pneumatic conveying systems. Generally, large-scale powder storage, metering, and conveying systems are used to convey ingredients. Business and system design should be carefully considered. In the architectural coating industry, such as the production line for producing real stone paint and colorful paint, because there are raw materials with high hardness, such as quartz sand, colored sand, etc., in the face of such granular materials with high hardness, wear-resistant materials should be considered. , Corrosion-resistant materials are used as materials for pneumatic conveying equipment, so as to improve the service life of the equipment.
