The large-diameter HDPE plastic-steel winding pipe is made of steel-plastic composite special-shaped belt material through spiral winding welding (extrusion welding on the lap surface), its inner wall is smooth and flat, and the specification is dn200-dn3000mm. This kind of pipe has the advantages of corrosion resistance, light weight, simple installation, large circulation, long life (50 years),
The main steps of the hot pressing process are as follows: Raw material preparation → mixing and heating → extrusion molding → cooling → demoulding The main process is extrusion molding using hot-melt raw materials of thermoplastics to be extruded and then cooled for molding. The main equipment is an extruder and a die. The detailed process flow is as follows: Plastic sheet production process,
The safe service life of HDPE double-wall corrugated pipe is more than 50 years. This has not only been proved by international standards and the new international, but also by advanced countries. Cement management theory has a service life of 20 years, but it is a silicate type, which is corroded by acid and alkali for a long time, and its service life is greatly reduced. There are instances of
Unique structure, high degree of automation, convenient operation, stable and reliable continuous production. The pipes produced by the PE water supply pipe production line have moderate rigidity, strength, good flexibility, creep resistance, environmental stress crack resistance and good thermal welding performance, and have become the first choice for urban gas pipelines and outdoor water suppl
With the increasing awareness of environmental protection, taking the path of healthy and ecological sustainable development has become the best choice for the packaging industry. As the most widely used plastic packaging material, degradability has become a trend. According to the different principles, degradable plastic materials are divided into the following three categories: biodegradable
50%, 100%, 150%, 200%... Recently, the domestic raw material prices have continued to rise, causing many downstream companies to complain, and from the perspective of transmission, due to the continuous crazy price increase in the upstream, the transmission speed of the price increase tide It is also very fast, beyond the imagination of many people. According to Coatings Purchasing Network, as
The aquaculture industry has received strong support from the state in recent years. The design of the new pig house is even more astounding. It can be described as a mansion. Many people even sighed that the second brother who ate, slept and ate now lives in such a big villa again! And those car slaves and house slaves who work nine to five or even more than ten hours are more than looking up. To
Recently, another term has become popular, wood veneer/wall panel or wood veneer wall panel. As the manufacturer of this wooden facing wallboard machinery and equipment, I think it is necessary to write something to tell people what is a wooden facing wallboard? How is this wallboard produced? What are his characteristics and advantages? Can it be used as an investment direction?
