Introduction of Polypropylene Fiber Polypropylene Fiber is pure polypropylene as raw material, through a unique process and equipment, after melting - extrusion - stretching - surface treatment - cutting and other processes refined, it has outstanding tensile strength and good dispersion, can be three-dimensional chaotic three-dimensional distribution in the concrete, so as to play a role in the concrete to resist cracking and pulling attached. Anti-crack fiber is a kind of anti-crack fiber which is made of 100% polypropylene as raw material, through unique technology and equipment, refined by melting, extruding, drawing, cutting and other processes, and it is a kind of anti-crack fiber which is specially added into mortar and cement concrete to play the function of crack-blocking and anti-seepage. In order to ensure that the anti-cracking fiber can be well dispersed in mortar and cement concrete, the anti-cracking fiber also undergoes a special process of surface treatment before cutting. Because it mainly uses polypropylene as raw material, it is also called Polypropylene Fiber. Anti-cracking fiber acts in mortar, cement concrete, relying on its unique tensile strength, dispersion, melting point, ignition point, acid and alkali resistance and other properties, can effectively prevent the mortar, cement concrete, the maintenance of cracks and development.
How Polypropylene Fiber Works?
The reason why mortar and cement concrete cracks is because of structural deformation cracking and no-load deformation cracks, structural deformation cracks are divided into cracks caused by external loads, cracks caused by foundation deformation, roadbed deformation, bridge deformation (differential settlement and differential expansion), and cracks caused by temperature difference of the structure; and no-load deformation cracks are divided into shrinkage cracks, plasticity cracks, concrete corrosion cracks, concrete reinforcing bar corrosion cracks, alkali - aggregate reaction cracks, vibration fatigue and inertial vibration-induced shear cracks. cracks, alkali-aggregate reaction cracks, shear cracks caused by vibration fatigue and inertial vibration.
Company information
The company's main import and export products include
(1)Organic Raw Materials are widely used and can be divided into three aspects: one is the raw material used to produce polymer chemical products, that is, the monomer for polymerization; the other is used in other organic chemical industries, including raw materials for fine chemical products; Used in solvents, refrigerants, antifreezes, gas adsorbents, etc. Basic organic chemicals are the basis for the development of various organic chemical products and are a major component of modern industrial structures.
(2)Intermediates:The chemical compound synthesized from simpler compounds and usually intended to be used in later syntheses of more complex products.A usually short-lived chemical species formed in a reaction as an intermediate step between the starting material and the final product.Our Intermediate products include Pharmaceutical Intermediates, Pesticide Intermediates and Dye Intermediates.
