What kind of insulating material is formed by the way?

anti static plastic sheet covers the type is too much, which will not be good at conducting current material called insulator, the material resistivity is often very high. Of course, insulators can also be divided into many categories, such as solid insulators there are plastic, rubber, glass, ceramics, etc .; liquid insulator refers to the natural mineral oil, silicone oil, trichlorobenzene, etc .; there are like air, carbon dioxide, Sulfur hexafluoride and the like.
The insulator has an obvious characteristic, that is, when it is under certain external conditions, it will be broken down "and converted into conductors, and it is not absolutely broken before the insulator is not absolutely conductive objects, if A voltage is applied across the insulating material, and a weak current is also present.
As an insulating material, there are many molding methods, if the substrate material in accordance with the different needs of different ways to shape. For example, resin-based g10 fiberglass molding methods are hand-paste molding, injection molding, fiber winding molding, molding, pultrusion, RTM molding, hot-pressing tank molding, diaphragm molding, migration molding, reaction injection molding, Stamping and so on.
The metal-based fibre washers is only solid-phase molding method and liquid-phase molding method, the former is below the melting point of the substrate temperature, through the application of pressure to achieve molding, including diffusion welding, powder metallurgy, hot rolling, hot drawing, Pressure and explosive welding. The latter is the matrix is ​​melted and filled into the reinforcement material, the traditional casting, vacuum suction, vacuum back pressure casting, extrusion casting and casting, etc. are liquid phase molding.
