As a composite covers inspection covers and explains its characteristics: the polymer as a matrix material, adding reinforcing materials, fillers and other caidian composite covers equipment, compounded by a certain process of inspection covers. Using unsaturated polyester resin matrix fiber reinforced thermoset composites, also known as bulk molding compound (DMC) East Lake composite covers production, made by compression molding technology, is a new type of environmentally friendly electricity cover. Composition and structure of steel fiber: to cut off the thin wire method, cold-rolled strip steel cut, molten steel ingot milling or rapid condensation method aspect ratio (the ratio of fiber length to its diameter, when the fiber is non-circular cross-section, using the equivalent conversion section diameter area of ??a circle) of 40 to 80 fibers. Due to the different properties of steel fiber preparation methods are very different, such as tensile strength of cold drawn steel wire 800-2000MPa, cold-rolled strip shearing tensile strength 600-900MPa, ingot milling method is 700MPa; molten steel condensing Although the law is 380MPa, but suitable for the production of heat-resistant fiber. Caidian composite covers equipment, was Wing Technology (certified), composite covers from Wuhan Environmental Protection Technology Co., Ltd. Rong was provided. Environmental Science and Technology Co., Ltd., Wuhan was Rong (www.crkjhb.com) (www.crkjhb.com) is Wuhan, a leader in environmentally friendly products processing, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs. In the form of wing technology leadership with the staff warmly welcome all inquiries negotiations to create a better form-technology future.
