company news about Electrostatic spraying powder equipment market development

Market supply and demand is an important factor affecting market changes. In the fierce market competition, whether enterprises and investors can fully understand market changes and make timely and effective decisions is the key to market victory. Timely understanding of market supply and demand is an important means for enterprises and investors to accurately grasp the direction of market development, and an important basis for assisting enterprise decision-making. As an important basis for enterprises to make raw material purchase, production and sales plans, the product market price trend is of great importance to the production, operation and development planning of enterprises. Especially after the global financial crisis in 2008, the price fluctuation of electrostatic spraying powder equipment products is large, making the profits of many companies in the industry decline, there are losses, and even bankruptcy. After entering 2009, under the situation that the national macro economy is gradually getting better, the market price of electrostatic spraying powder equipment products and its future trend have become the object of close attention of enterprises and investors. Since entering the 21st century, the scale and characteristics of China's market have undergone great changes, and the operation and management of enterprises have also begun to transform from the past single goal development to systematic and scientific management. How to understand the development of the electrostatic spraying powder equipment industry and the change of the market from a professional perspective, how to effectively manage all levels of the enterprise with scientific methods, will become the primary problem for the survival and development of the enterprise in the future. But there are still a lot of business thinking is still stuck in the early days of entrepreneurship, without a proper planning and executive control, just by feeling and the owner's personal likes and dislikes to manage. Moreover, in the overall management process, due to the lack of relevant professional and management skills of business owners or managers, the management process control means are changeable, and the managed appear confused or contradictory. The operation and management of the enterprise is chaotic, which leads to the decline of the overall performance of the enterprise staff, and the lack of enterprise ownership and security. In this way, the vicious circle will be introduced, and the position of enterprises in the market will be precarious. The operation and management of enterprises need systematic and scientific knowledge, and can not be done overnight. To this end, we have specially produced this report. Use a professional perspective to help enterprises understand the electrostatic spraying powder equipment industry, broaden their ideas, clear their heads, and guide enterprises to quickly and effectively find ways to improve the competitiveness of enterprises. Electrostatic spraying is a kind of spraying method which uses high voltage electrostatic electric field to make the negatively charged paint particles move in the opposite direction of the electric field and adsorb the paint particles on the surface of the workpiece. Electrostatic spraying equipment is composed of spray gun, spray cup and electrostatic spraying high voltage power supply. Powder electrostatic spraying equipment mainly includes: powder spraying room, high voltage electrostatic generator, electrostatic spraying gun, powder feeder, powder recovery device, workpiece rotation mechanism, etc.
1. Powder room
Powder spraying room is one of the main equipment for electrostatic coating of powder. Maintaining a smooth air flow is the cleaning of the powder room and provides a clean working environment for the operator. Control the dust content in the spray room so that it is below the explosion limit (generally set at 10g/m3). In addition, the powder spraying room should be conducive to cleaning, so that the powder is not easy to deposit in the room, so as to change the color of the powder, and there should be enough light in the room to facilitate the coating work.
2. Electrostatic spray gun
Spray gun according to its use can be divided into portable powder gun, fixed automatic powder gun, disc spray gun, etc. It is divided into internal electric gun and external electric gun according to electric type. According to the form of its diffusion mechanism, it can be divided into conflict guns, rebound guns, secondary air inlet guns, centrifugal cup guns and so on.
The charged mechanism form of the duster gun will be a key factor in improving the spraying efficiency.
In general, the core of the dusting equipment is the spray gun and the charging system. As far as the current market is concerned, the corona spray gun accounts for a large proportion, which is because the advantage of charging the powder by using high voltage corona discharge is that it can spray all kinds of thermosetting powder coatings today, and can obtain very good results. Its main advantages are excellent stability, powder rate and powder speed.
The development of this type of spray gun is like this: voltage control, current control, total energy control. The total energy control is a component with the distance of the spray gun to the workpiece, and its voltage and current are constantly adjusted to the ideal state to achieve the painting effect.
3. Powder supply system
(1) The powder supply system is to continuously and evenly transport the coated powder from the powder container to the powder gun for spraying.
The powder supply system is composed of air compressor, oil-water separator, air dryer, regulating valve, compressed air pipeline, electromagnetic control valve, powder supply device, powder delivery pipeline, etc.
(2) The form of powder feeder
In the powder electrostatic spraying powder supply system, there are many types of powder suppliers used, which can usually be divided into: pressure vessel type, screw or rotary mechanical conveying type, Wenli air suction type.
(3) Powder recovery device
4. Powder recovery can be divided into wet method and dry method.
The wet method is to filter the air with powder through the liquid container to achieve purification, and the powder with liquid is dried and reused. The dry method powder recovery is to collect the powder particles in the powder air flow discharged from the powder chamber. The types of dry powder recovery are gravity sedimentation, inertia separation, cyclone separation, sintering plate separation, etc. In actual production, multi-stage recovery device is often used to achieve better separation
