We can also see from the literal meaning of cable aluminum foil Mylar. It must be an aluminum foil Mylar tape applied to cable. How is it applied? What role does it play? I'll explain it to you one by one——
The high-temperature line has the characteristics of high temperature resistance, corrosion resistance, aging resistance and climate resistance. To achieve these qualities, it generally requires a lot of data combination and special technology processing. In production, in addition to the primary materials, auxiliary materials are also necessary.
1. Filling materials include: polyester fiber, cotton yarn and PP rope. The intention is to adhere to the roundness of the cable, reduce the amount of rubber, reduce the cost, and increase the strength of the cable. Among them, polyester fiber is often used for wires with high tortuous demand.
2. Separate data, including: cotton paper, polyester tape, foamed PP tape, talc / mica powder, silicone oil, DOP, b.t.a.
(1) Core cotton paper, polyester tape, foamed PP tape, wrapped paper tape when the wire is laid, which can make the wire round and ensure the peeling.
(2) Talc powder / mica powder: when the outer surface is pushed out, the PVC surface of the core wire and the coated PVC are heated and simply adhered together. Talc powder / mica powder is used for isolation, which can ensure peeling and handling adhesion. High temperature resistant fireproof cable.
(3) Silicone oil is sprayed when the insulation is pushed out. The primary purpose is to improve the adhesion between the conductor and the insulation, which is used to ensure the peeling between the insulated high-temperature cable and the outer cover.
(4) DOP is used between conductors and insulation to improve the adhesion between conductors and insulation.
(5) B.t.a. the solution is applied to the outer surface of the conductor when the insulation is pressed out. The primary function is to avoid oxidation of the bare copper wire.
3. The shielding materials include: cable aluminum foil Mylar tape, weaving wire and oblique wrapping wire. Shielding can effectively avoid mutual interference inside and outside the shielding layer.
