What are the main factors affecting the process of PP Self Wrap Braided Sleeve?

If the Cable Sleeve wants to be processed into a PP Self Wrap Braided Sleeve, it must go through the Braided Sleeve, so what factors will affect the process of the PP Self wrap braided sleeve? The editor summarizes the following three points for your reference.

1. Sulfur dosage

The greater the dosage, the faster the knitting speed and the higher the knitting degree that can be achieved. The solubility of sulfur in the Cable Sleeve is limited, and excess sulfur will be precipitated from the surface of the rubber, commonly known as "sulfur spray". In order to reduce the phenomenon of sulfur injection, it is required to add sulfur at the lowest possible temperature, or at least below the melting point of sulfur. According to the use requirements of Pp Self Wrap Braided Sleeve, the amount of sulfur used in soft Cable Sleeve generally does not exceed 3%, the amount used in semi-rigid rubber is generally about 20%, and the amount used in hard rubber can be as high as 40%. %above.
2. Braided Sleeve temperature
If the temperature is 10°C higher, the knitting time will be shortened by half. Since the Cable Sleeve is a poor heat conductor, the weaving process of the finished product is different due to the temperature difference of each part. In order to ensure a relatively uniform knitting sleeve degree, thick PP Self Wrap Braided Sleeve generally use gradual heating and low temperature knitting sleeves for a long time.
3. Knitting sleeve time
This is an important part of the sleeve weaving process. If the time is too short, the degree of weaving sleeves is insufficient (also known as sulfur deficiency). If the time is too long, the degree of weaving sleeves is too high (commonly known as oversulfur). The best overall performance can only be guaranteed with an appropriate degree of knitting sleeves (commonly known as positive knitting sleeves).
