For customers with a spacious environment, good site management (such as floor paint), no dust pollution, no strong wind interference, no high temperature radiation, techuang technology believes that it would be better not to build isolation room. But only a few customers have the above conditions, most of them will choose to build an isolation room to isolate the spray room, so as to avoid the external environment pollution to the powder and the interference to the recovery system. The customer's choice of isolation mode in the construction of isolation room:

The first method mentioned above is used by many customers. This method has relatively high requirements for equipment configuration and structural design. After many customers use some immature equipment in this way, there are some problems such as serious powder overflow and internal heat tightness in the isolation room, which lead to the operators unable to enter the enterprise;

Relatively speaking, the second method is more and more recognized by some new and old customers. This method has relatively low requirements for equipment configuration and structural design, affordable price, durable, relatively low use cost, and good effect.

However, when spraying the products with high quality requirements, the recycled powder will inevitably be contaminated by dust, sand, fiber and so on. At this time, the powder screening machine with 120 mesh or more screen should be equipped to screen and mix with the new powder to avoid quality problems;

The third way is also a closed-circuit external circulation system which is being designed by the mechanical and Electrical Technology Department of Dechuang. This way will solve the shortcomings of the above two ways, but the cost of the whole set of equipment is relatively increased!
