Production method of insulation sheaths of power source lines

Abstract

The invention discloses a production method of the insulation sheaths of power source lines. The production method comprises the following steps of: S1, raw material selection: a proper quantity of anylon material and a PVC material is selected; S2, granulation: the selected nylon material and PVC material are prepared into particles by using a granulator; S3, raw material inspection: the color,granularity and uniformity of the nylon particles and the PVC particles are inspected, so that the quality of the raw materials can be ensured; and S4, drying treatment: the nylon particles are placedin a vacuum rotary dryer, a vacuum pump is used for pumping air and humid, so that a vacuum state is formed in a working chamber, and the vacuum degree of vacuum pumping should reach 0.05 MPa or above. Compared with other production methods, the production method has the advantages of low price, space-saving performance and mature process. With the production method adopted, insulation sheaths have good heat resistance and have excellent mechanical and physical properties; the tensile strength of the insulation sheaths is more than 5 times of that of polyvinyl chloride; the insulation sheathshave high flexibility, good wear resistance, high self-lubricating performance and good oil resistance; and the insulation sheaths can withstand sunlight irradiation or ultraviolet long-term irradiation, and therefore, the insulation sheaths have good sunlight aging resistance and longer service lives.

Description

technical field [0001] The invention relates to a processing technology of a power cord, and more specifically, relates to a production method of an insulating sheath of a power cord. Background technique [0002] Power cords are wires that carry electricity. Usually the way of current transmission is point-to-point transmission. Power cords can be divided into AC power cords and DC power cords according to their uses. Usually, AC power cords are wires that pass through high-voltage alternating current. Due to the high voltage, such wires require uniform standards to obtain safety certification before they can be formally produced. The DC line basically passes DC with a lower voltage, so the safety requirements are not as strict as the AC line. However, for safety reasons, countries still require unified safety certification. Generally, in the production of power lines, their outer skins need to be produced. [0003] However, most of the production methods of power cord sh...

Problems solved by technology

[0003] However, most of the production methods of power cord sheaths currently on the market have relatively single functions and are very inconvenient to use. The traditional power cord sheaths do not have excellent mechanical and physical properties because they are made of PVC materials. Poor, and the softness is poor, and the sheath extruded by the traditional production method will foam, such as foam, granules or damage, which is not suitable for mass production. Therefore, we propose a power cord insulation sheath production method
