Refinement of the microstructure of antistatic plastics

Time: 2018-08-30 12:09 Author: admin Hits: Times
There are two main molecular structures of antistatic plastics: one is a linear structure. A polymer of this structure is called a linear polymer; the second is a host structure, and a polymer having this structure is called a host polymer compound.

Some polymers have branched chains, called branched polymers, which have a linear structure. Although some polymer molecules have cross-connections, they have fewer cross-connections, called network structures, which belong to the body structure. Two different structures exhibit two opposite properties.
The linear structure has meltability, hardness and brittleness. The body structure has high hardness and brittleness. Plastics are two polymers. Thermoplastic polymers are made from linear polymers. Thermoset plastics are made from bulk polymers.
Anti-static plastic molding: blister. After the plate is heated to a certain temperature, it is adsorbed on the surface of the model with a vacuum pump, and the plate is transformed into bubbles or bubble shells of different shapes by cooling and setting.
Compression molding, also known as compression molding, is mainly used for the molding of thermosetting plastics such as phenolic resin, urea resin, unsaturated polyester resin. Extrusion, also called extrusion, is a method of extruding a heated resin through a die and extruding a desired shape with an extruder.
Extrusion is also sometimes used for the molding of thermosetting plastics, and can be used for the molding of foam plastics. The advantage of extrusion is that the product can be extruded into various shapes. High production efficiency, can realize automatic and continuous production. The disadvantage is that thermosetting plastics cannot be widely used, and product sizes are prone to deviations.
Blow molding is also called hollow blow molding or hollow blow molding. Blow molding is a method of inflating a hot resin blank in a mold under the pressure of compressed air. Blow molding includes two methods of blown film and blown hollow article.
Calendering is a molding method that removes two or more wet rolls, processes them into a film or sheet, and then peels off from the calender rolls of the calender, then cools the resin and various additives by cooling. Calendering is mainly used in the molding method of PVC resin, which can produce products such as film, sheet, board, artificial leather, floor tile and so on.
