Advantages of PPH winding storage tank
Pph spiral wound storage tank is a large plastic storage tank, and it is also a promising plastic storage tank at present. The advantage of ppH winding can mainly lies in the change of processing technology, which makes the ppH winding can stand out from other cans. PPH mixing tank
The processing of pph spiral wound storage tank mainly consists of three core points: tank production, internal and external weld welding, and manhole installation. These three core points will affect the integrity, aging resistance, leakage prevention, service life, mechanical strength and other properties of the tank.
Pph winding tank body is processed and produced by the spiral extrusion winding technology imported from Europe. The PpH particles are fused on the spiral extrusion winding device, and then the fused extrudate forms a can body on the mold. Demoulding after the temperature is reduced to a certain extent can ensure the integrity of the tank body. Compared with the traditional processing form, the plate is welded to the tank, because the width of the plate is 2000 mm, and the height of the water tank is usually more than 2000 mm. In the actual processing, it is a part of the tank, and then it is manually welded to form. In order to ensure safety, the water tank is jointly filled with a reinforcing ring.
The comparison of the two processes shows that the pph around the storage tank is directly made of pph granular material, without secondary processing. Traditionally, granular materials are processed into plates, and then the plates are processed into grooves. In addition, the pph wound storage tank has no seams, welding problems, and no leakage, and the overall mechanical strength is far greater than that of the traditional manual process storage tank because of no chamfer welding.
The bottom plate of the pph winding tank is an automatic welding extrusion welding unit. The welding seams of the top plate and the floor plate adopt the long arm extrusion welding unit, and the traditional processing technology is adopted. After chamfering, manual welding is mainly used. The grain of the welding rod is produced, and the degree of manual welding cannot be controlled. The materials and electrodes are difficult to dissolve into a whole, and the integrity is poor, Pph process winding tank can avoid this problem. In addition, the manual weld is slightly higher than the tank body, while the pph winding tank is formed by drag welding with a certain radian, and the weld is 50mm higher than the tank body.
The process of manhole of plastic storage tank is very important. Manholes are usually opened at the bottom and top of the water tank. For maintenance and observation, the manhole of pph wound storage tank is welded with a large automatic extrusion gun. The principle is the same at the bottom of inner and outer plate welds. Similarly, the traditional processing technology is manual welding.
To sum up, pph spiral wound storage tank has the advantages of good integrity, corrosion resistance, leakage resistance, aging resistance, stable quality, high weld strength, high aesthetics, no flickering weld, etc., which is far superior to the spiral wound storage tank made by traditional processing technology. It is expected that the domestic plastic can market will be dominated by pph wound cans within one year.
