Summary
The definition and manufacture of isolation rooms
Definition
In the spraying process, a completely enclosed or semi-enclosed room or enclosure structure specifically designed for the painting and powdering process sections of workpieces to ensure the quality of painting. The isolation room is equipped with good ventilation, constant temperature and humidity functions
manufacture
▲ The frame is made of steel structure, with stainless steel at the bottom ▲
The middle part is made of transparent tempered glass, and the top is decorated with a ceiling
▲ It is made of sandwich color steel plates and edged with aluminum materials ▲
The middle is transparent tempered glass with a suspended ceiling
The function of the isolation room
a. Ensure the quality of the coating
b. Prevent contamination by external dust and impurities
c. Avoid the influence of through drafts
d. Separate each spraying area
e. Meet the requirements of constant temperature and humidity for spraying
Factors influencing the temperature inside the compartment
Is there a supply and exhaust air system in the compartment
1. The supply and exhaust air system is similar to the internal and external circulation of an air conditioner. If there is one, the air in the compartment can be replaced in time to ensure a constant temperature. At the same time, the timely replenishment of fresh air also guarantees that workers can breathe healthy air. If not, the temperature will rise more rapidly.
2. The exhaust method of the spraying equipment.
If an internal circulation is used, the heat generated by the equipment operation will accumulate to a certain extent, causing a relatively rapid temperature rise. If external exhaust is adopted, most of the generated heat will be dissipated, and the temperature will rise slowly.
The distance between the compartment opening and the entrance of the curing oven
3. Under normal circumstances, after the workpiece is painted or powder-coated, it enters the curing oven for curing. If the distance is relatively close (less than 8 meters), hot air will flow back into the compartment, causing the temperature inside the compartment to be too high.
4. The structure of the factory building.
The compartments in higher factory buildings (with a clear height of over 7 meters) have lower temperatures, while those in lower factory buildings (with a clear height of less than 5 meters) have higher temperatures.
Factors influencing the temperature inside the compartment
5. Equipment power
The greater the total power, the more heat is generated and the higher the temperature.
The smaller the total power, the less heat generated and the lower the temperature.
6. Season
If it is in summer or autumn, the temperature in the compartments will be relatively high.
If it is in spring or winter, the temperature will be relatively low.
summary
The temperature of the compartment is not influenced by just one factor; it is usually the result of the interaction of multiple factors. If the isolation room is not made in accordance with the standards, it will affect the operation of the spraying equipment and the quality of the products, shorten the service life of the equipment, increase the maintenance and repair costs invisibly, and cause occupational safety and health problems for the operators who work in the high-temperature isolation room for a long time. Therefore, We suggest that customers consult professional companies when manufacturing isolation rooms to create a good working environment. This not only saves usage costs but also enhances competitiveness.
