Main features of fiberglass tubes 1. Good corrosion resistance. Since the main raw material of FRP is composed of polymer unsaturated polyester resin and glass fiber, it can effectively resist the corrosion of acid, alkali, salt and other media and untreated domestic sewage, corrosive soil, chemical wastewater and many chemical liquids. Erosion, in general, can maintain safe operation for a long time. 2. Good anti-aging performance and heat resistance. The glass fiber tube can be used for a long time in the temperature range of -40 ° C to 70 ° C. The specially formulated high temperature resistant resin can work normally at temperatures above 200 ° C. 3. Good antifreeze performance. Below minus 20 ° C, no cracking will occur after freezing in the tube. 4. Light weight and high strength. The relative density is between 1.5 and 2.0, only 1/4~1/5 of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, and the specific strength can be compared with high-grade alloy steel. As a result, it has achieved excellent results in aerospace, rockets, spacecraft, high-pressure vessels, and other applications that require weight reduction. 5, can be designed. Flexibility in designing a variety of structural products to meet the requirements of use, can make the product has a good integrity. 6, good wear resistance. The water containing a large amount of mud and sand was loaded into a pipe to carry out a comparative test on the rotational wear. After 3 million rotations, the wear depth of the inner wall of the test tube is as follows: the steel pipe coated with tar and enamel is 0.53 mm, the steel pipe coated with epoxy resin and tar is 0.52 mm, and the surface hardened steel pipe is glass steel pipe. It is 0.21mm. Therefore, the FRP has good wear resistance. 7, electrical insulation is good. FRP is a non-conductor. The electrical insulation of the pipe is excellent. The insulation resistance is 1012-1015 Ω·cm. It is most suitable for transmission. The heat transfer coefficient of the fiber-reinforced steel in the dense area of ​​the telecommunication line and the multi-mine area is very small, only 0.23. In five parts, the insulation performance of the pipeline is excellent. 8. The frictional resistance is small and the conveying capacity is high. The inner wall of the glass tube is very smooth, and the roughness and friction are small. The roughness coefficient is 0.0084, while the concrete pipe has an n value of 0.014 and a cast iron pipe of 0.013. Editor in charge: Wang Zhen Wall sconce is a lighting fixture installed on a wall, usually made of metal, glass, or plastic. They can provide direct or indirect light, used to illuminate a room, hallway, foyer or other indoor space. Wall sconces are typically mounted on walls and can be used in conjunction with ceiling lights or table lamps to provide more lighting options and visual layering. They can also be used for decorative purposes as they come in various shapes, colors, and design styles to match different interior decor styles.
