Plastic extrusion, also known as plasticating extrusion, is a continuous high volume manufacturing process in which a thermoplastic material -- in a form of powder, pellets or granulates -- is homogeneously melted and then forced out of the shaping die by means of pressure. In screw extrusion, the pressure comes from the screw rotation against the barrel wall. As the plastic melt passes through the die, it acquires the die hole shape and leaves the extruder. The extruded product is called extrudate.
High speed mixers are rotor/stator agitators used for more challenging solid-liquid dispersions and emulsions, which high-speed dispersers cannot adequately process. This type of mixing device typically features a four-blade rotor turning at high speeds within a stationary stator. As the blades rotate, materials are continuously drawn into the mixing head and expelled at high velocity through the openings of the stator. The resulting hydraulic shear promotes fast homogenization, deagglomeration and emulsification. Rotor tip speeds between 3,000 and 4,000 ft/min are typical.
The pipes used to transport potable drinking water in a home plumbing system use different materials than those used for the pipes carrying drain water. Your home may have a plumbing system that uses all one type of material for the water supply pipes, but don't be surprised to find several types of pipes, especially in older homes that have seen many repairs or updates. Here are some common materials used for water supply pipes.
First you must determine what type of pipe you want to produce. For standard HDPE and PPR pipe there are single screw extruders and twin screw extruders for PVC pipe. The reason PVC piping requires a Double or Twin Screw Extruder is to ensure that the PVC powder is properly mixed. Since PVC powder is a rough material a second screw is required to mix it without damaging the extruder. On the other hand, for PE pipe production a Single Screw Extruder is up to task.
Recently, a batch of large-diameter and high-density pipe extrusion lines with diameters of 315-630mm were sent to Uzbekistan. This batch of production lines is a new type of pipe production line successfully developed by our company with advanced technology, digestion and absorption.
1. Inspection before starting the mixer (1) Whether the electrical equipment is in good condition, check whether the lifting oil pressure, mixing shaft, mixing blade and other rotating parts are faulty and clean. (2) Check whether the mixed materials meet the requirements of the formula. (3) The mixing tank or mixing tank must be fixed, otherwise it cannot be turned on. (4) When the high speed mixer is started, it should be started under light load, and heavy load is not allowed.
