PP is a kind of semi-crystalline material. It is harder than PE and has a higher melting point. Due to the high crystallinity, the surface of the material stiffness and resistance to scratch characteristics very well. PP doesn’t have the problem of environmental stress cracking. Moreover, it could offer significant resistance to any chemical or acid. PP pipe is a kind of plastic pp made of copolymerized polypropylene resin and extruded. It has lightweight, has good chemical stability, heat resistance, insulation, high mechanical strength and is non-toxic. At present, the PP pipe connection mode widely used in construction is:1. welding sleeve socket welding method 2End edge welding method. 3. dissimilar material takeover: used in petroleum, chemical, chlorine alkali, dye, agriculture, food, medicine, light industry, metallurgy, wastewater treatment, water supply, drainage, etc.
The pp air duct is suitable for corrosive gas pumping and exhausting pipes. Specific industries include electroplating, chemical, electronic, and pipe fittings. Sheets, pipes, and other main product materials used in the production and installation of air ducts, PP air ducts have the characteristics of high-temperature resistance, convenient pipe connection (heat welding, electric welding, pipe connection), and recyclability. Let’s analyze its performance advantages with the editor:
pp air duct has excellent performance of low thermal conductivity. There are countless independent bubbles that are not connected to each other. The thermal conductivity of the gas in the bubbles is low, so as to achieve an excellent heat insulation effect. At the same time, this closed bubble structure prevents water vapor from entering the material smoothly, even on the outer surface. Damaged, because the vapor bubbles are not connected to each other, the water vapor is still isolated. Instead of closed-bubble structure material, water vapor can penetrate deeply into the material and cause insulation failure.
Macromolecules are inorganic materials, which cannot be achieved by ordinary foaming materials when encountering acidic and alkaline substances.
Because it is mainly an inorganic component, only the surface is carbonized in case of fire, and the material is not deformed. All indicators of the pp air duct meet the national standards.
After testing, the polymer has no harm to the human body, which is unmatched by glass fiber.
According to the requirements, the air leakage can be reached zero.
pp air duct is mainly used in farmland water delivery systems, building water supply systems, heating systems,s and chemical pipeline systems, etc. It also has good hygienic performance, heat resistance, heat preservation, and energy-saving, easy installation, reliable connection, raw materials that can be recycled, the pipe requirements are simple, the production process is simple and easy to control, and the pipe layout is free.
How to select the PP air duct needs to be determined according to the application requirements. If it is used for exhaust gas exhaust, calculate the total air volume, unit: cubic meter/hour. Design the flow velocity of the gas in the PP duct, unit: m/s, divide the airflow by the flow velocity and wait until the cross-sectional area of the PP duct, after opening the root, multiply it by 2 to get the diameter of the pipe.
