Polypropylene industrial silk refers to all polypropylene filaments other than clothing. Its production process and use are obviously different from clothing fiber. Polypropylene industrial silk or high-strength polypropylene fiber can be obtained by selecting polymer and high-specification polypropylene raw materials, improving the tensile degree and crystallinity of macromolecular chains, and reasonably controlling the spinning, drawing and heat treatment processes. Linear density, modulus, strength requirements are high, elongation at break and elongation requirements are generally low.
Characteristics of ppolypropylene industrial silk:
1. Shape: The vertical surface of polypropylene is flat and smooth, and the cross-section is circular.
2. Density: The biggest advantage of polypropylene is light texture, its density of only 0.91g/cm3 is the lightest variety of common chemical fibers, so the same weight of polypropylene than other fibers to get a higher coverage area.
3. Strong elongation: polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. So polypropylene wear resistance is good. In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is the ideal material for making fishing nets and cables.
4. Hygroscopic and dyed polypropylene have very little hygroscopic properties, almost no hygroscopic properties, and the moisture regain rate under general atmospheric conditions is close to zero. However, it has a core suction effect, which can transfer water vapor through the capillary tubes in the fabric, but does not have any absorption effect itself. The dyeing property of polypropylene is poor and the chromatography is incomplete, but the method of stock solution coloring can be used to make up for the deficiency.
5. Acid and alkali resistant polypropylene has good chemical resistance, in addition to concentrated nitric acid, concentrated caustic soda, polypropylene has good resistance to acid and alkali, so it is suitable for filter materials and packaging materials.
6. Light resistance and other polypropylene light resistance is poor, thermal stability is also poor, easy to age, not resistant to ironing. However, the anti-aging properties can be improved by adding anti-aging agents during spinning.
Polypropylene wire made of polypropylene industrial silk, because of its low price, high strength, anti-aging, wear resistance, salt water corrosion resistance, good elasticity and other characteristics, polypropylene industrial silk is mainly used in sewing cement bags, fertilizer bags, plastic woven bags, fishing net weaving and other industries.
Geotextiles woven with polypropylene industrial silk, suitable for roads, railways, airports, seawall, canals, reservoirs, ports and Bridges and other projects, with no need to break, build cofferdams, dam drainage and speed, high efficiency, investment province, good quality and other advantages, especially in the case of large load, woven geotextiles than non-woven geotextiles have many unique features. Using its acid and alkali resistance, corrosion resistance, high strength, no water absorption, light weight, good stability, good filter stripping and other advantages, can be made of high-strength polypropylene fiber filter cloth, mainly used in metallurgy, mineral processing, chemical industry, light industry, food, environmental protection and other industries.
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.
