At present, my country's plastic pipeline industry has moved from a traditional pipeline country to a pipeline powerhouse, and has gradually got rid of the situation of single pipeline varieties and limited application fields in the past. In recent years, the development of my country's plastic pipe industry has embodied the trend of technological innovation leading the industry. The output growth rate of traditional pipes has slowed down, and some new and functional pipe varieties have developed rapidly.
At present, the overall technical level of my country's plastic pipe industry presents some new features, which are mainly reflected in:
New materials continue to emerge, and high-performance materials are on the market; pipeline compounding technology has been rapidly developed, and functional plastic pipes have gradually seized the high-end market; plastic pipe processing equipment has been developed simultaneously, and some have high-efficiency extrusion technology, precision extrusion technology, and online There are more and more equipment for monitoring technology and diversified pipeline composite technology; advanced system design concepts are emerging one after another, and the application fields of plastic pipelines are rapidly expanding.
First, the pace of upgrading of new materials is accelerating, and high-performance materials are on the market, constantly replacing traditional backward materials, such as oxygen-barrier PB composite pipes and PE-RT composite pipes, which can effectively solve the oxygen barrier of traditional PB and PE-RT single pipes. Poor technical problems. In addition, for some specific market needs, adopting some advanced reinforcement, toughening technologies and functional composite technologies to improve the formulation of materials has become a trend in the development of the industry. For example, antibacterial PPR composite pipe products have an anti-bacterial rate of 99.9%. , The antibacterial effect is very significant, and the water transported through the pipeline can be directly drunk.
The second is the rapid development of pipeline composite technology. Plastic has many recognized unique advantages, but its low strength is its obvious disadvantage. Through the combination of plastic and metal, plastic and fiber, plastic and functional material, the performance of ordinary plastic pipes is further optimized, and the application fields of the original pipes are further expanded.
Third, the pipeline processing technology has made great progress. Injection molding and extrusion molding are the most important molding methods in the plastic pipe industry. In order to realize the development direction of "precision, energy saving and high efficiency" injection molding technology, injection molding technology has been extended from the initial innovation of the injection machine itself to the innovation of process and mold, and the upgrading of injection molding machine equipment is getting faster and faster. . Extrusion molding technology is suitable for almost all thermoplastics, and energy saving has become the development direction of extrusion equipment. In addition, precision extrusion technology and wiring technology for electrofusion pipe fittings have also become hot spots in the industry. In the future, the production automation level, online inspection and control level of the plastic pipe industry will become higher and higher.
Fourth, the continuous emergence of new markets promotes the development of the plastic piping industry in the direction of piping systemization, and the requirements for the supporting capabilities and system design capabilities of the piping system will become higher and higher. Such as trenchless laying and repairing of water and compressed air pipelines in harsh environments such as deep mines and deep mines, high-pressure natural gas pipelines, and plastic pipelines with special properties required in various fields such as the chemical industry, electronics industry, and power industry, such as Pipes for transporting various highly corrosive fluids in the production of chemical products, pipelines for transporting highly pure water in the production of electronic products, and pipelines for transporting strong abrasive media in power stations, etc.
