01  Brief Introduction of Spray Type Pretreatment for Powder Coating/Spraying

Our Zhyao spray-type pretreatment equipment ensures even and efficient application of pretreatment chemicals onto workpiece surfaces. Using precision spray nozzles, it disperses a fine mist of pretreatment solution, ensuring complete coverage. The system allows adjustable parameters like spray pressure, flow rate, and chemical concentration to meet diverse substrate and coating needs.

Process Stages:

• Degreasing

• Rinsing

• Surface Activation

• Conversion Coating

Advantages:

1. Compatible with automated conveyor systems for improved production efficiency.

2. Equipped with ventilation systems to prevent hazardous gas buildup.

3. Built with stainless steel shed bodies, cylinder blocks, and spray pipes, featuring precision welding for a lifespan exceeding 15 years.

Inspection&Package

Pretreatment:

Three Types: Immersion / spraying /shot blast
Customized design based on products' requirements: rinse, degrease, chemical rust removal, silane,pottery,phosphate, pure water rinse,etc; 
The shed is made of stainless steel/PP, beautiful and durable, with a high degree of automation, it is equipped with exhaust fan to prevent the mist spill over out.

If the solution need to be heated,it will be equipped with heating device and the tanks will be designed double layer.In the tanks,there are filters to clean the recycled solution,so the impurities will be separated and easy to clean the tanks.
In the beginning and ending of  the shed,there will leave one meter of space to ensure the mist will not spread out, at the top of the shed,there are two rows of rushes to prevent the solution  polluting the chain.So  the conveyor can serve a long time.
There are exhaust fans and waste gas treatment device ,so it eco-friendly.


Curing Oven/Drying Oven:

Curing oven system. Divided into bridge type and tunnel type.
The tunnel oven has a wind curtain at both ends ,so the heat will not loss, which saves the fuel. This is our patent.And tunnel oven is suitable for long and thin products,like pipes;
The bridge oven is installed on the metal frames,the burner chamber is under the oven,so save space,and people can cross the oven from the bottom,products can transport from the bottom,save manual labor;and the bridge oven is suitable for most of the products which are not so long;
The oven is made of galvanized plate inner and outside,the middle insulation is 150 mm rock wool.


Advantages:

1.Same Heat Distribution: The temperature is kept consistent and the temperature difference is controlled within ±3°. This uniformity is the key for stable quality;
2.Adjustable: It can be designed to suit different sizes, shapes of products, meeting various of requirements.
3.Save Energy : It is equipped with Pneumatic doors to prevent heat loss;

Type	Item	Specification
Bridge curing oven And Tunnel curing oven	Conveyor chain speed	Adjustment according to work piece specification
	Furnace temperature	180-220°adjustable
	Heating time	≤35mins,usually 15-20mins
	Temperature rise curve	Work piece at room temperature to 200°,5-6mins,curing 10-12mins
	Heat energy	Gas,electricity,LPG,diesel,multiple options

Powder Coating Booth:
The powder coating booth is made of PP board,looks beautiful,anti-static,the powder will not adsorbed on the surface;in the bottom of the booth ,there is compressed air to blow the powder into the recovery system;in this way it allows workers to clean the booth quickly;there is a centrifugal fan which creates negative air pressure,under the action of negative pressure the powder can not spill over out,ensure the clean working environment;

There are lifters on both sides of the powder coating booth,the spraying guns are installed on the lifters;the lifers is PLC controlled,can move up and down,left and right,even in circle,the Moving Path depend on the workpiece;before the powder coating booth,there are scanners in the post which can scan the workpiece, so the dimension of the workpiece can transport to the control system, which produce an order to the lifter, the whole process is fully automatically.
And there is a shaking machine in the powder supply center,when the powder comes out of the cyclone,enters the shaking machine, in this machine,a filter in it,through shaking and moving ,the powder becomes clean.then for reuse.
