The problem of ultra-thick plastic welding technology that has been plaguing plastic products companies has been solved recently. The new program-controlled plastic welding technology developed by Hebei Hengshui Anti-corrosion Equipment Engineering Co., Ltd. not only realizes high-quality disposable welding of ultra-thick plastic products, but also can be widely used in polypropylene, polyethylene and other materials.
According to reports, the technology uses preheating and screw extruder integrated design, high welding strength and good sealing effect. Especially for plastic products with a wide weld and a thickness of 30 mm or more, it can be welded at one time, and the mechanical strength of the weld is close to that of the welded body. After testing, the product indicators fully meet the requirements of the German welding specification DVS2209-1 technical standards, comparable to the German MUNSCL company technology, can meet the requirements of large-scale anti-corrosion equipment in the domestic petrochemical industry.
The technology realizes the automation of hot air preheating, solder heating melting and extrusion plasticization in the plastic welding process. The new spiral extrusion process further improves the welding quality of the ultra-thick plastic products, and the new welding process can make the plastic processing arc The welding is formed once and the quality of the oversized chemical container equipment of more than 300 tons is better.
At present, the technology has been applied to disinfectant tons of projects in Hebei, Shandong and other places, PVC piping installation, large-scale sewage pool PVC soft plastic lining anti-corrosion, silicone project 300 cubic meters storage tank and chlor-alkali project 500 cubic meters Engineering projects such as sodium hypochlorite tanks.
