1. The cyclone and filter element recovery device in powder spraying is an advanced rapid color-changing powder recovery device. It is suggested that the key components of the powder spraying system should be imported, and all the components such as the powder spraying room and the electric mechanical elevator should be localized.
2. The oven is one of the important equipments in the painting production line, and its temperature uniformity is an important index to ensure the painting quality. The heating modes of oven include radiation, hot air circulation and radiation heating air circulation, which can be divided into single chamber and straight-through type according to production procedures, and the equipment forms include straight-through type and bridge type. The hot air circulating oven has good thermal insulation, uniform temperature in the oven and less heat loss. After testing, the temperature difference in the oven is less than plus or minus 30 degrees Celsius, which can reach the performance index of similar products in advanced countries.
3. The electrical control of painting production line includes centralized control and single row control. In centralized control, programmable controller can be used to control the upper computer, and each process can be automatically controlled according to the programmed control program, and data can be collected, monitored and alarmed. Single-row control is the most commonly used control method in painting production line. Each process is controlled by single row, and the electric control box is set near the equipment, which has the advantages of low cost, intuitive operation and convenient maintenance.
4. The hanging conveyor is the conveying system of industrial assembly line and coating line, and the stacked hanging conveyor is applied to the storage shelf of special-shaped street lamps with L= 10- 14M and the coating line of alloy steel pipes. The workpiece is hoisted on the special hanger, and the turnout smoothly enters and exits, and the turnout is electrically opened and closed according to the work instruction.
The above is a brief introduction to the performance of plastic injection line system. Our company's plastic spraying assembly line has won the trust and unanimous praise of users at home and abroad. Here, we sincerely look forward to cooperating and communicating with you, and let us work together to create a better future. During the production, transportation, storage and construction of coatings, the volatilization of solvents will cause serious pollution to the atmosphere or water, and bring physical harm to operators. If the plastic spraying assembly line is not properly kept and operated, it is easy to cause fire, and it is also difficult to treat waste paint. It does not contain any solvent, and is a coating with 100% solid content. Its manufacture, transportation, storage and construction have solved the pollution problem caused by solvents, improved the working conditions of operators and benefited their health.
1. 1.2 Simplify painting process and improve painting efficiency.
When painting by painting process, it is necessary to spray primer, putty, water mill, topcoat and varnish. Three grinding and three copying; Ten to twenty processes, with a processing cycle of seven to ten days. The plastic spraying process only needs spraying, curing and cooling to form a film at one time. Greatly simplifies the painting process, shortens the production cycle, and can produce products on the same day. In powder coating electrostatic coating, automatic coating machinery and recycling system can form automatic production, thus saving energy and resources and improving production efficiency.
1. 1.3 powder coating has high utilization rate and can be recycled.
Compared with paint, powder paint can be directly coated on the surface of the coated object, and a coating film can be formed after baking and curing. Uncoated powder can be recycled and sent to the powder supply system for use, which greatly reduces the loss of paint in construction. The utilization rate of powder coating is above 95%, while the uncoated coating is difficult to recover except the solvent is completely volatilized, so the actual utilization rate of general coating is about 50%.
1. 1.4 powder coating has good performance and durability.
High-performance coatings with various functions can be prepared by using resins that are insoluble in solvents at room temperature or polymer resins that are insoluble and liquefied. In addition, when the powder coating is prepared or formed into a film, no solvent is added or released, and pinholes penetrating through the coating film are not generated, so that the coating film is more compact. Compared with paint coating, powder coating is more durable.
