There are two kinds of copper and aluminum cores, and the diameter of a single core is 1.76 mm, 2.24 mm, and 2.73 mm, respectively. The proportion of the plastic coating and the core material used varies with the thickness of the coating layer and the core diameter. The wire diameters of the above three types of wire cores coated with PVC...

Cable material and its variety Cable material refers to the plastic used for the insulation and sheathing of cables. Commonly used plastics include PVC, PE, PP, PA and fluorine plastics. PVC cable material Wide variety of PVC cable materials, widely used. The voltage resistance and insulation resistance of PVC cable materials are relatively high,...

Plastic wire and cable (hereinafter referred to as "cable") refers to a cable using plastic as an insulating layer and a jacket layer. There are many varieties of plastic cables.
The basic structure of plastic cables is to use plastic as an insulating layer on the outside of copper and aluminum wire cores. Some of the conductive cores consist of...

(1) Extrusion: With an extruder with a mixing screw, the screw aspect ratio varies depending on the type of plastic. The head used is a hanger type head. The baffle in the nose adapter has a mixing effect. However, the presence of a baffle will increase the shear rate, increase the heat, break the macromolecular chains, and decompose the material....

1. Unwinding: Always keep proper tension when unwinding the substrate. In order to stabilize the composite extrusion, edge control systems are used to detect the end of the substrate in pneumatic or photocell mode.
2. Tacking of the substrate: In order to allow good adhesion between the substrate and the melt extruded plastic film, active groups...

Non-plastic base material and plastic material pairing: Composite film should be based on the packaging requirements, select different adhesive base materials to cooperate in order to achieve the best results. Therefore, the choice of composite materials is crucial. Before the pairing of the substrate is removed, the following factors cannot be...

Extrusion coating plastic substrate: a plastic film can also be used as a composite of another plastic film substrate, such plastic films are: PP and PE blown film, PE cast film, cross-linked EP film, PP cast film and biaxially stretched film, EVA film and EVA hydrolyzate film, PVA film, PET film, nylon film and PS film and so on.
Non-plastic...

(1) Cellophane: The raw material of cellophane is a natural cotton slurry rather than an ordinary silicon glass film. Since natural cotton is also a polymer material, some scholars have classified cellophane into plastic films. Cellophane is "not moisture-proof" and "moisture-proof". Non-moisture cellophane (ie, plain cellophane) contains 2% to...

(1) Paper has the characteristics of being non-toxic, rigid, opaque, easy to print, and good adhesion, but also has the disadvantages of flammability, high permeability, poor moisture and moisture resistance, and low mechanical strength. The types of paper used for compounding include kraft paper, cardboard, candy paper, release paper, and the...

(1) Trimming is generally available in three ways. The razor blade type is the simplest and can be used for the trimming of thin composite films such as tissue, cellophane and plastic films. Daggers are used for trimming of various substrates. Shear type is used for trimming of medium and high gram papers and hard substrates.
(2) There are three...
