Introduction to swimming immersion pretreatment
Characteristics of swimming immersion pre-treatment: The workpiece is transported in the medicine pool by means of suspension line conveying. It has the characteristics of continuous operation in large quantities, good treatment effect, easy maintenance, and small dosage of syrup. Relatively occupying a large area, and can only be placed on the ground for a variety of shape and high grease content of the workpiece processing, not suitable for floating work.
Introduction to the swimming immersion pre-processing function:
1. The seven components of the powder coating line mainly include: pre-treatment, dusting system, powder recycling system, painting equipment, curing and drying equipment, heat source system, electronic control system, suspension conveyor chain and so on.
2. The pre-treatment is mainly to clean the stain on the surface of the aluminum profile, and form a layer of chrome film on the surface to make the preliminary work for the dusting.
3. Pre-treatment process: basket → degreasing → water washing → (alkaline etching) → water washing → surface adjustment (neutralization) → water washing → chromizing → water washing → hot (pure) washing → dripping dry → drying → sending spray rack (Flexible adjustment according to the characteristics of the workpiece) Among them: the concentration of degreasing, alkali etching, surface adjustment, and chromizing agent is based on the concentration provided by the supplier. The washing tank is made of ordinary tap water, and the hot water is washed with pure water. (Alkaline erosion can be used)
Classification and introduction:
The pre-treatment is divided into three types: spray type, swimming immersion type and submersible type. The processing method can be flexibly selected according to the specific production requirements of the workpiece.
A. Spray type: The spray type treatment method uses the spray principle to continuously apply the liquid to the surface of the workpiece. It has strong work continuity and high efficiency. It is suitable for large-volume operation requirements and has good treatment effect. It is suitable for larger pipe fittings. , long pieces and simple structures, and generally adopt a high structure to save floor space.
B. Submersible swimming: The submersible treatment method is carried out by hanging the chain, allowing the workpiece to be immersed in the swimming pool and processed in the liquid pool. It is suitable for the processing of various complicated shapes, and the effect is good and the dosage of the medicine is saved.
C. The swimming immersion treatment method is to use the crane to immerse the workpiece in the liquid medicine tank, and complete the treatment of the surface of the workpiece through physical and chemical methods. Suitable for workpieces with complex surfaces and severe rust. The degreasing and the film tank are provided with a gas pipe, and the treatment liquid is stirred according to the specific condition of the workpiece, and a heating device can be arranged in the liquid medicine tank to improve the treatment effect.
