What influences the strength of polypropylene high strength wire? Here are a few things to tell you.
1. Melt index affects the strength of polypropylene high strength wire
Under the same spinning temperature, the same stretching ratio and the same technological parameters, the lower the melting index of polypropylene slice, the higher the strength of polypropylene filament.
In a word, at a certain spinning temperature, when the melting index of the raw material is low, the high strength can be achieved under the condition of low tensile ratio, if the melting index of the raw material is high, the high tensile ratio is needed to achieve a certain strength.
Polypropylene fiber * can reach 7.0 ~ 7.9cN/dtex, it is widely used: filter cloth, geotextile, sling, conveyor belt and so on.
2. Tensile ratio affects the strength of polypropylene high strength wire
With the increase of the stretching ratio, the strength of the fiber increases, which has a greater impact on the strength of the fiber.
3, tensile speed tensile speed of polypropylene high strength wire strength
In the one-step polypropylene fiber spinning line, the drawing speed is approximately equal to the spinning speed. The orientation and crystallinity of fibers are affected not only by the stretching ratio but also by the stretching speed.
Different drawing speed, that is, different spinning speed, its fiber strength is different, polypropylene fiber fiber strength decreases with the increase of drawing speed.
For the same raw material, the finished product can reach the required strength by adjusting the stretching ratio, spinning speed, spinning temperature, steel blowing temperature and wind speed, etc. The polypropylene fiber with high strength and good quality can be produced by reasonable coordination of technological parameters.
Xuzhou Heping Chemical Fiber Co., Ltd. is located in Xuzhou, Jiangsu. It has focused on the research and development and production of polypropylene, high strength, high strength, high strength, high strength, anti-aging, acid and alkali resistant, etc., which also make polypropylene high strength. Wire can be applied to all aspects of our lives. Peaceful chemical polypropylene, manufacturers supply, complete products, high quality after-sales service, users can rest assured to buy. Peace chemical fiber also has a polypropylene industrial silk, polypropylene high strength wire, high-strength polypropylene wire, polypropylene high strength, high-strength propylene, and hydrazine industrial wire.
