1. Equipment

The winding unit adopts advanced imported extrusion winding equipment. The winding unit is equipped with external pad welding machine, internal long arm welding machine and flat butt welding machine. In order to improve the processing accuracy and work efficiency of product accessories, the company is equipped with advanced auxiliary production equipment such as precision engraving machines, horizontal table saws, and Laidan plastic welding guns imported from Switzerland.

2. Raw materials:

PPH winding tank The raw materials of the tank are new imported plastic particles and master batches of the same color. The tank bottom, tank top, flange nozzle and other accessories are processed and produced with designated new materials.

3. Can body winding: plastic particles are heated and melted on the spiral extrusion and winding unit, and extruded and wound on the mold to form a can body. After the temperature is reduced to a certain extent, the mold is demoulded to obtain a complete cylindrical tank body. Process.

Winding process: preheat the equipment → select the mold → install the mold → clean the mold → heat the mold → extrude and wind the wire → cool down → measure and cut → demould → reset the mold → check the tank body → enter the next process.

Process characteristics: high production efficiency, good tank integrity, good corrosion resistance and leakage resistance, smooth and beautiful tank, thin top and thick bottom, low cost, unlimited tank size and shape, and good anti-aging performance.

4. External welding of tank bottom: the imported full-automatic extrusion disc welding unit is used to connect the tank bottom plate with the external weld of the cylinder, so as to realize the one-time welding of large welds.

Internal welding of tank bottom: the imported full-automatic extrusion long arm welding unit is used to realize the welding process of large weld at the joint of tank bottom plate and outer shell weld.

Process characteristics: high degree of mechanization and automation, stable product quality, weld specifications can be designed according to the product stress characteristics, so that the integrity of the weld can be fully utilized. The product integrity is good, the weld is integrated with the parent body, corrosion resistance, water leakage resistance, less flash, and the weld is flat and beautiful.

5. Installation of nozzle accessories: the welding gun imported from Switzerland is used, and the tank accessories such as flanges and joints are installed on the tank body by experienced technicians to integrate them with the tank body. This process is PPH storage tank 。 The next process of the produced zui.

Process flow: determine the specification and quantity of nozzle accessories and prepare → determine the position of nozzle accessories on the cylinder block → make holes on the cylinder block as required → install welding flanges → weld flange stiffeners → assemble flange protective cover or flange blind plate plate → carefully check and confirm.

Features: PP storage tank has excellent corrosion resistance and sealing performance, light weight, beautiful appearance, and is more reliable than plastic roll molding process, plastic sheet welding, glass fiber reinforced plastic winding, hand lay up process, carbon steel lining process and other processes.

Use: This product is an ideal chemical anti-corrosion medium equipment for chemical, pharmaceutical, printing and dyeing, food and other production industries.
