The laboratory flame-retardant pps air duct valve body is light and handy, easy to operate, free of welding, and short welding joints. When the pipeline is longer than the coil, it can be used to lay lower trenches on the pipeline. When the construction is restricted, it can be welded. It is a high-toughness pipe with an elongation at break exceeding 500%. It has strong adaptability to uneven settlement and displacement of pipeline foundation and good impact resistance. The laboratory flame-retardant pps air duct is used for air transportation and distribution. In occupations such as semiconductors, paint spraying, chemicals, and beverage factories, the requirements for ventilation duct systems are getting higher and higher, and metal pipes have fallen far behind plastic pipes.

The inner wall of the duct fittings such as the flame-retardant pps air duct in the laboratory is evenly lubricated, and the pipe movement resistance is small, and it will not scale. The pp pipeline can transport various degenerate media at 90°C. The laboratory flame-retardant pps air pipe can be corroded by a high concentration of acid and alkali with a PH value of 1 to 14 in a wide temperature range, and its rigidity and load-bearing strength are better than traditional plastic pipes. The laboratory flame-retardant pps air duct material belongs to polyolefin, and its composition is only composed of C and H elements. The raw and auxiliary materials are completely clean and standardized, have good degradation resistance, and have no chemical infection and corrosion to all ions in the water. When the hot water pipe needs to heat the laboratory flame-retardant pps air pipe, it is suitable for direct burying and concealment of the embedded wall and the ground.

The laboratory flame-retardant pps air duct has a very good sound insulation function, which can significantly reduce the vibration and noise caused by liquid activities. Due to the elasticity of polypropylene, the cross-section of pipes and pipe fittings can expand together with the refrigerant without cracking. The pipe is a poor heat conductor, which can reduce condensation and heat loss. Good heat resistance, long service life, high pipeline grade, up to 95°C. Under the pressure of 1.0 MPa, the temporary use temperature is 70°C, which meets the normal hot water supply temperature. When the laboratory flame-retardant pps air pipes are kneaded together to form, the molten raw materials from the extruder gradually become ring-shaped, so that the raw materials are well melted together. Therefore, the engine needs to be equipped with separation equipment such as a separation cone and a separation support frame.

The laboratory flame-retardant pps air duct is plasticized and melted, and the material is extruded into the mold with a fixed amount and constant pressure, and then transported to the designated runner. Under the action of pressure and temperature, the laboratory flame-retardant pps air pipe is assembled in the mold area, extruded from the molding section of the mold, and cooled to form, to obtain the processing method required for the composite profile. Laboratory flame-retardant pps air duct can be widely used in various professional production, that is, it depends on the actual material selected. Pipe products are widely used in chemicals, environmental protection, clean food and building water supply and drainage.
