Flexible Wind Dust Network The product is greater than or equal to 95% of high-density polyethylene, the production of raw materials by adding anti-UV agents, anti-aging agents, flame retardants, crosslinking fortifier; fire safety factor, flame longer than 4S ; solid and durable, tensile coefficient 220KN / MM, impact factor satisfies GB16909-1997. Structural features of the flexible safety net dust high-density polyethylene, high density polypropylene as raw material, adding a variety of chemicals in the raw material, through a special process is made; the product has a high coefficient of fire safety, good flame retardant, anti- static, solid and durable, good high tensile strength, toughness, and other characteristics. Due to the excellent quality of raw materials, in the natural environment is relatively long life! Flexible security curtain dust processed into different colors, appearance is better, but the technology of low cost, easy to install. An investment in long-term benefit, basically no maintenance. Flexible application range safety curtain dust coal field, mining, sand dust and other regions is quite extensive. Features 1, weaving using a special weaving, weaving a unique network nodes effectively, even if man-made damage occurs, it will not linear open end, and repair simple and convenient to use under normal circumstances, almost no maintenance costs. 2, impact resistance, because the net body of a flexible material, flexibility is very good. Can withstand hail (strong winds) the impact, strong impact resistance. 3, flame retardant flexible security curtain dust will be added in the production of flame retardants, flame retardant properties through qualified, fully meet production safety requirements. 4, anti-ultraviolet (anti-aging) contains UV mesh body of the chemical composition, can absorb ultraviolet light, effectively extending the service life. Single flexible security curtain dust Dust effect of up to 65 to 85 percent, double the network settings patented technology can greatly enhance the effect of wind and dust control, dust suppression effect of up to 90%, effectively limiting the secondary dust occur. Flexible production process safety curtain dust mixing: The first part of the dust curtain flexible security, mainly to carry out mixing ingredients into blender. Drawing: Flexible safety curtain dust produced second link is the most important one. Netting: Flexible safety curtain dust produced a third aspect, by mechanical devices will become woven wire mesh, woven mesh width between 2-5 meters. Length can be extended indefinitely. Cutting sewing: Flexible Production Safety dust curtain fourth session, according to the customer's size requirements, flexible security crop dust curtain sew customer specifications required. Net mounting: Use rope, galvanized nuts, U-shaped line card, U-shaped line card base, pvc tie wire and other accessories fixed. Flexible security dust curtain works is the use of flexible safety curtain dust aerodynamics, according to the implementation of on-site wind tunnel results processed into a certain geometry, opening rates and different combinations of wind and dust shaped hole wall, so that the flow of air (strong wind) through the wall from the outside, on the inside of the wall to form the airflow to reach the outside interference of strong winds, low wind medial, lateral little wind, no wind, the effect of the inside, to prevent dust emissions. The technology is currently in the leading position. Flexible security curtain dust by independent foundation, steel support, Windshield three parts. Dust piled material is divided into two categories: one is static dusting material yard surface; the other is in the process of stacker reclaimer and other dynamic dusting. The former is mainly with the material surface moisture, wind speed and other closely related, the latter mainly to job gap, associated with handling strength. For dynamic bulk yard when only external wind speed reaches a certain intensity, the wind makes the pile surface of the particles produced is sufficient to overcome the upward migration of friction and other impediments to migration of particles and particle gravitational force between the particles themselves, granules left Stacking raised surface, called the starting point of the wind speed wind speed. According to the experimental study of open-air windrow diffusion of dust, material piled relationship between the amount of dust and wind speed as follows: Q = a (V-V0) Where: Q ............... .. Stockyard dusting rate wind speed V0 ............... V ............... .. coefficient dust from a .................. wind speed and particle size distribution of dust-related n ................... exponent (n> 1.2) can be seen from the equation Q piled the material difference between the amount of dust wind speed (v-v0) high power is proportional. Because the actual wind speed decreased feed yard is to reduce the amount of dust from the most effective way. Can also be seen from the above equation, the amount of dust piled material Q becomes small, the main approach is to reduce the "V-V0" difference. Flexible security settings dust curtain purpose is to V smaller, wet dust suppression purposes V0 is larger, so as to achieve the purpose of reducing Q. So for open yard, using flexible security curtain dust is the main technical measures to reduce the amount of dusting
