High strength polypropylene industrial silk detailed introduction!

High strength polypropylene industrial silk is a kind of fiber material with high strength properties, which is synthesized from polypropylene as raw material, and is widely used in many fields. Here is a detailed description of it:

Performance characteristics:

High strength: Compared with ordinary polypropylene fibers, the strength of High strength polypropylene industrial silk is significantly higher, which makes it able to withstand greater tension and load, and can be used for products with higher material strength requirements, such as ropes, seat belts and other applications, to ensure safety and reliability during use.

Light weight: polypropylene is currently a lighter proportion of all fibers, the same weight, polypropylene fiber coverage is wider. For example, when making a shoulder bag webbing, it not only makes the webbing light, easy to use and carry, but also reduces the overall weight of the product to a certain extent.

Good wear resistance: has excellent wear resistance, in the long-term use and friction environment, can still maintain good performance, such as in some industrial conveyor belts, ropes and other products, the wear resistance of high-strength polypropylene industrial silk can improve the service life of the product.

Acid and alkali resistance: acid, alkali and other chemical substances have a good tolerance, suitable for some may be exposed to chemical substances in the environment, such as filtration materials in the chemical industry.

Anti-aging: with good anti-aging performance, in the long-term exposure to the natural environment or the use of the process, not easy to appear aging, embrittlement and other phenomena, to ensure the long-term stability of product performance.

Production process:

Raw material preparation: The selection of high-quality polypropylene slices as raw materials, the quality and performance of the final high strength polypropylene industrial silk quality is crucial.

Spinning process: Usually using melt spinning method, polypropylene slices are heated to a molten state, and then extruded through a spinneret to form a fine filament. In the spinning process, it is necessary to strictly control the temperature, pressure, extrusion speed and other process parameters to ensure the quality and stability of the fiber.

Tensile shaping: The spun filament is stretched so that the molecular structure of the fiber is aligned along the axial orientation, thereby increasing the strength. At the same time, the heat setting treatment can eliminate the internal stress and stabilize the size and performance of the fiber. Drawing process conditions such as drawing multiple, temperature and time need to be precisely adjusted and optimized according to product requirements.

Post-treatment: including oiling, winding and other processes. Oiling can improve the lubricity and antistatic property of the fiber, which is convenient for subsequent processing and use; Winding is to wind the finished fiber into a cylinder in accordance with certain specifications and requirements for storage, transportation and subsequent processing.
