Structure composition of pretreatment and coating line

Composition of coating line  

The components of the coating line mainly include: pre-treatment equipment, dusting system, painting equipment, oven, heat source system, electric control system, suspension conveyor chain, etc.  

Pre-treatment equipment  
Spray type multi-station pre-treatment unit is a common surface treatment equipment, its principle is to use mechanical scouring to accelerate the chemical reaction to complete oil removal, phosphating, washing and other processes. The typical process of spray pretreatment of steel parts is: pre-degreasing, degreasing, water washing, water washing, surface adjustment, phosphating, water washing, water washing, water washing.  Shot blasting cleaning machine can also be used for pre-treatment, which is suitable for steel parts with simple structure, serious corrosion, no oil or less oil. And no water pollution.

Powder spraying system  
Small cyclone filter element recovery device in powder spraying is a more advanced powder recovery device with faster color change. The key part of dusting system is recommended to choose imported products, dusting room, electric machinery lifts and other parts are all made in China.

Paint spraying equipment
Such as oil spray paint room, water curtain spray paint room, widely used in bicycles, car leaf springs, large loaders surface coating.

Oven is one of the important equipments in coating production line, and its temperature uniformity is an important index to guarantee coating quality.  Oven heating methods are: radiation, hot air circulation and radiation hot air circulation, according to the production program can be divided into single room and through type, equipment form straight-through and bridge type.  Hot air circulation oven heat preservation is good, uniform temperature in the furnace, less heat loss, after testing, the temperature difference in the furnace is less than?  3oC, to achieve the performance index of advanced similar products.

The heat source system
Hot air circulation is the most commonly used heating method at present. It uses the principle of convection conduction to heat the oven.

Mobile phone shell coating production line
The workpiece can be dried and solidified.  Heat source can be selected according to user’s specific situation: electricity, steam, gas or oil, etc. Heat source box can be set according to the oven: placed on the top, bottom and side. If the circulating fan of production heat source is specially made to withstand high temperature, it has the advantages of long life, low energy consumption, low noise and small volume.
