New inorganic non-metallic composite material system by E-long glass fiber, unsaturated resin, and other inorganic chemical materials molded from high temperatures, does not contain any metal materials, light weight, fire, environmental, aesthetic, easy construction, toughness Well, may be cut, etc., is very suitable for applications that require frequent maintenance ditch canal and cover. The new inorganic non-metallic materials causing pollution in the production and use are not on the environment, cement, wood, plastic, steel and other ideal alternative. During the national policy "Eleventh Five-Year", the state will vigorously develop the circular economy and build a resource-saving and environment-friendly society to achieve sustainable development; vigorously promote energy, water, land, materials products, forced out of high consumption heavy pollution, the technology behind the processes and products; to encourage the production and use of energy-saving products, the development of land-efficient buildings; restrict the use of clay brick; the strengthening of industrial pollution control, speed up coal-fired power plant sulfur dioxide control, strengthen the comprehensive utilization of resources, etc. . This project uses new fiber-reinforced composite material production and the cable trench cover compared with the traditional method, with less raw material, the use of inorganic fiber reinforced seldom or never use steel, mass per unit area can greatly reduce the traffic light in the production and use the process without any pollutants, in full compliance with the "Cleaner Production Promotion Law, People's Republic of China," the provisions of the requirements and policy orientation. This project is in line No. 6 January 23, 2007 the National Development and Reform Commission, Ministry of Science, the Ministry of Commerce, Intellectual Property Office jointly issued the "high-tech industry key field guide current priority development (2007)," Chapter IV of the announcement fifty-three spirit of the document. "Inorganic composite cable trench cover" a market analysis, most of the cable trench and cover market usage of existing products on the market today use (over 95%) are ordinary cement slab (concrete reinforcement bars), and another five about% organic materials, and organic materials can not withstand the sun blowing points, easily deformed, the use of ordinary cement materials, in order to achieve the required strength must increase the thickness of steel and built to prevent falling weathering must be surrounded by channel edging, This increase reinforced concrete ditch cover does not have the plasticity and extremely cumbersome to transport, installation and maintenance has brought great inconvenience. Extensive use of steel waste and costs associated with increased resources. "Nagasaka inorganic composite cable trench cover" 2, the principle of non-metallic inorganic alkali-free glass fiber length is a brittle material has a high compressive strength, flexural strength and relatively low tensile strength, impact strength and crack resistance poor. Such as Portland cement is a kind of traditional inorganic nonmetallic E-long glass. Now the cable channel use / cover all cement products, thus strengthening the production of steel to use, in order to achieve greater strength required cover thickness, weight increases, the process of using the edge chipping easily collapse. E-glass fiber with respect to the terms of the long glass fiber has a high tensile strength and high modulus of elasticity. A certain amount of E-glass fibers to the formation of long glass fiber composite materials, can be effective 1 + 1> 2. Such as FRP composite material is glass fiber polymer composite materials or fiberglass cloth and epoxy resin, phenolic resin formed, has been widely used to make car bumpers, pedestrian bridges and so on. However, inorganic non-metallic alkali long glass fiber tend to have strong alkaline, glass fiber will be severe corrosion, thereby losing enhance the role, but it will also appear chalking intensity dips and other fatal flaws. For this purpose a non-metallic inorganic alkali as long glass fiber reinforced fiberglass body must be of special glass, which can withstand the erosion of the base to a certain extent. The project selection and alkali-resistant fiberglass mesh as a reinforcement. Magnesium oxychloride adhesive is a relatively low alkalinity, inorganic non-metallic green E-long glass, sulfur cement also has low alkalinity. Therefore, this project chooses two E-long glass as the base material. With as an adhesive base material and plays the role of reinforcing glass fibers have been possible to produce fiber-reinforced composite materials, but still face the problem of high density materials developed for this purpose a filler material having a nano-scale pore structure of the item, which is filled the composite material can reduce the weight and would not significantly reduce its strength, so as to achieve a lightweight, high-strength effect. "Nagasaka inorganic composite cable trench cover" 3, the product features (in the cable trench cover, for example) 3.1 lightweight, fireproof about 60kg per square meter, construction, easy to move, easy to plant, power station indoor and outdoor cable channel The overhaul. At 1200 ℃ burnt out fire flammable, non-explosive off, fire performance up to the national A-level. 3.2 beautiful, uniform application of inorganic composite decking disposable mold casted, so go the whole surface, uniform size. Cover the surface with a unique non-slip tread design, both from the non-slip effect, but also improve the overall perception of the cover, changing the shape of the rigid cement cover previous shortcomings, in line with the current construction of a modern garden-type substation, the standard power plant aesthetic requirements. "Inorganic composite cable trench cover 3.3" to save energy, easy construction. Due mainly by E-long glass fiber, unsaturated resin made from environmentally friendly materials, do not use steel as the ribs, can save a lot of steel, while avoiding rust steel cover damage caused by corrosion, and because the material particularity, the new materials to replace steel bearing, toughness coupled with the product itself, to achieve this product can be nailed, planed, can be cut, reducing the difficulty of the cover design, greatly reduces the difficulty of construction, while easily solved shaped cover Prefabricated problem. 3.4 waterproof outdoor cable trench cover plate with curved design, can effectively bypass the rain to both sides, cover the surface of the water to prevent the same time, due to the straight plane cover corners can be done, geometry structured unity, so cover the gap between the minimum connection, which can effectively prevent water leakage. 3.5 aging resistance, toughness, ease of maintenance products from a variety of inorganic composite materials made through the high and low temperature aging test performance, manual handling, maintenance is not easy to destroy, to extend the life of the product, any move, not out corner edge collapse. Fourth, the project vision, inorganic composite cable trench cover with innovation and technology, with the continuous improvement of the market, as consumers recognize the advantages of the new material continues to deepen, the scope of application of new inorganic non-metallic composite materials will greatly expand , new inorganic non-metallic composite materials will become the mainstream of construction materials, promotion and application of composite materials, is the degree of social civilization signs, through special selection and structural design of the product performance to meet the high-performance integrated indicators, while reducing engineering cost, has become a major advancement in the field of new materials, it is in this market context driven, taking into account the premise of conventional steel, cement and organic materials, and other similar product features, the company introduced a new type of inorganic composite cable trench cover products using inorganic materials, E-long glass, mineral fillers, fibers, polymers and special stress structural framework, combined with advanced production technology and a composite made with lightweight high-strength, high temperature resistance thaw excellent, easy construction and other characteristics, will be used to change, power stations, subway stations, railway, municipal pipelines cable channel bracket, water pipelines, home decoration materials, ventilation pipes, agricultural greenhouse bracket, wall fence other occasions.
