Polypropylene rope is a kind of packing rope often used by people. With the continuous improvement of living standards, polypropylene rope has been gradually produced to help us bind things. But not all polypropylene ropes are good. Today, let's learn about the quality of polypropylene ropes.
First, let's understand the production of polypropylene rope. The film head thickness of polypropylene rope should be adjusted evenly, and the set temperature of each point should be accurate. If the temperature is too low, the raw materials are easy to produce particles. If the temperature is too high, the raw materials will be alienated, which may cause holes in the film surface. The cooling damper should be appropriate. If the damper is opened too large, it is easy to cause membrane tube shaking and instability. If the damper is too small, the cooling force is not enough, and the membrane surface is easy to wrinkle. The speed ratio of front and rear pulleys shall be accurate.
The recycled polypropylene rope has short meters and low tension, and its quality is obviously inferior to that of the polypropylene rope produced with new materials. Finally, during the use of polypropylene rope, the rope cannot be knotted, nor can the hook be directly hung on the polypropylene rope to avoid damaging the polypropylene rope. Secondly, various parts on the polypropylene rope shall not be removed arbitrarily.
