Plastic ductwork, is a ductwork for air transport and distribution. Such as laboratory ventilation duct system, mall air conditioning duct system, factory exhaust gas discharge duct, industrial ventilation duct, etc.
Plastic ductwork is divided into PP ductwork and PVC ductwork. PP ductwork has a wide range of applications, low cost, acid and alkali corrosion resistance, easy welding and processing, and PVC air ducts have high production costs and complex processes.
According to the cross-sectional shape, air ducts can be divided into circular air ducts, rectangular air ducts, oblate air ducts, etc. Among them, circular air ducts have small resistance but large height and size, and are complicated to manufacture. Therefore, the application is mainly based on rectangular ducts.
PP ventilation duct: strong ventilation capacity; stable acid and alkali resistance, corrosion resistance and temperature resistance, prevent secondary chemical reaction between the medium in the pipe and the pipe body, and reduce the difficulty of purification treatment of industrial waste gas and waste liquid; PP Plastic ductwork can be directly connected with flanges , the installation is simple and convenient, and the installation efficiency is greatly improved. PP plastic air duct is used in the treatment of exhaust and exhaust gas of corrosive gases in workshops. It has good construction performance. The plastic ductwork is light in weight, convenient for installation and replacement, and low in overall project cost.
Material: Polypropylene is abbreviated as PP, which is a colorless, odorless, non-toxic, translucent solid substance. PP (polypropylene) is a thermoplastic synthetic resin with excellent performance, which is a colorless and translucent thermoplastic lightweight general-purpose plastic. It has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties.
PP PLASTIC DUCTWORK can be widely used in industrial chemical industry, environmental protection, food cleaning, building water supply and drainage, etc. It can transport various corrosive media below 90 degrees Celsius. Its rigidity and compressive strength are superior to traditional plastic pipes.
Superior sound insulation and heat insulation performance:
The polymer air duct has the excellent performance of low thermal conductivity. There are countless independent bubbles that do not communicate with each other inside the material. The thermal conductivity of the gas in the bubble is extremely low, so as to achieve excellent thermal insulation effect; at the same time, this closed-cell structure makes it impossible for water vapor to enter the material smoothly, even if the outer surface Damaged, the water vapor is still isolated because the bubbles are not connected to each other. In contrast to materials with a closed cell structure, water vapor can penetrate deeply into the material, resulting in thermal insulation failure.
Polymer synthetic materials, with the characteristics of acid and alkali corrosion resistance, are widely used in the chemical industry.
High flame retardancy:
The improved PP Plastic ductwork has good flame retardant properties. The best V-0 PP ductwork can not melt and drip when burning at high temperature, and it will automatically extinguish within 10 seconds after leaving the fire source. Minimize fire damage as much as possible.
The polymer has been tested, and it has no harm to the human body, and does not produce black smoke and harmful gases when burned.
