The price of ordinary CaCo3 powder is much cheaper than plastic, the addition of CaCo3 powder will reduce the cost of plastic products. The CaCo3 powder is called filler. At present, The main purpose of adding CaCo3
The mechanical principle of the extruder is to add water or appropriate liquid into the raw powder and stir it continuously, and then extrude the well-mixed material from the porous head or metal mesh with high
In recent years, with the implementation of the “plastic ban”, biodegradable plastics have gradually entered the public’s vision, which is of vital significance for the development of environmental protection packaging industry. At present, there are
The choice of extruder depends mainly on what material the plastic needs to be recycled by the customer and what output is required per hour. if the customer produces PP recycling and granulation, the required output is 100~150kg/h, the raw material particles are large but the plasticization requirements are not high, the CSE-65 single screw extruder is the most suitable.
The machine model is mainly determined according to the customer’s output. The L/D of the twin screw extruder is the higher the better. It is usually required to be more than 40 with a high cost-performance ratio. Generally, the 52mm, 65mm, and 75mm twin screw extruders are more popular with customers. The triple screw extruders of 52mm, 65mm and 75mm have a higher output and better mixing effect than the twin screw extruders of the same model.
Underwater pelletizing system is the most widely used particle granulation system at present. It is mainly composed of drive valve, die head, pelletizer head, water circulation system and pipe fittings, dehydration and drying system, vibration
3D printing metal materials are mainly in the form of powder and wire. Powder materials are the most commonly used materials, which can be used in a variety of 3D printing processes such as Selective
The underwater pelletizing line is generally composed of start-up valve, die head, pelletizer, water bypass system and pipe fittings, centrifugal dehydrator and control system. Underwater pelletizing line is a kind of “Hot-face cutting”. When uniform high-temperature
3D printing technology is an intelligent manufacturing technology that originated in the 1980s and integrates machinery, computer, numerical control and materials. The basic principle of this technology is that according to the two-dimensional section information
Twin screw extruder is used to extrude molten plastic through a fixed shape extrusion mouth under the action of the screw, and cut it after being water-cooling or air-cooling. It is used in the filling, blending,
PVC has been widely used in the production of cable materials because of its excellent corrosion resistance, electrical insulation, especially its flame resistance and self extinguishing. PVC cable material is pellet prepared by mixing, kneading and
Filling masterbatch refers to the mixing and mixing of various additives, fillers and a small amount of carrier resin for the convenience of operation in the process of plastic processing and molding. The design of filling masterbatch formula has only fixed design concept and purpose, and there is no fixed formula. Different formulas of different equipment and processing environment of powder need to be adjusted properly.
Color masterbatch is a special colorant for new polymer materials. Different types of color masterbatch have different uses. However, color masterbatch is basically used for coloring products such as plastics, pipes, packaging, electrical enclosures, films, moisturizing materials, clothing fibers, and improving unique properties.
After the continuous fiber bundle (carbon fiber or glass fiber) is unwound by the unwinding device, it is pre tensioned and pre dispersed by the pre tensioning roller, and then the upper and lower surfaces
PVC cable material is a pellet prepared by taking polyvinyl chloride as the base resin, adding plasticizers such as stabilizer, dioctyl phthalate, diisopropyl phthalate, dioctyl terephthalate, trioctyl trimethylene terephthalate, and inorganic fillers such as calcium
The template of the extruder is composed of a die plate body with a discharge hole and a thermal insulation layer, and is fixed to the die head with a threaded rod. Only when the
Extruders can be divided into single screw extruder, twin screw extruder and multi screw extruder according to the number of screws. Single screw extruder is suitable for extrusion of general materials. The laboratory twin screw extruder has the advantages of
Twin screw extruder is an important equipment in plastic processing machinery. It is not only suitable for extrusion molding and mixing processing of polymer materials, but also has been widely used in food, feed, electrode,
