The production technology of high-efficiency energy-saving slurry spray pipes used in desulfurization tower installations has finally been broken by foreign monopolies. Recently, Hebei KNT Fiberglass Co., Ltd. independently developed the slurry glass steel spray pipe production process for desulphurization towers to obtain national invention technology patents.
The spray pipe is the key device for effectively controlling the equipment to deal with the flue gas. At present, the domestic production technology of energy efficient slurry spray pipe is monopolized by foreign countries. According to Li Xiaofeng, deputy general manager of the company's process design inventor, the product solves the impact of the full reaction of gas and limestone solution in the wet flue gas desulfurization process on the spray pipe, and developed the inner liner and outer surface layer. The addition of a wear-resistant material to the production of a new process results in a corrosion-resistant and impact-resistant structural layer, which greatly increases the abrasion resistance of the spray pipe and extends its service life to more than 30 years. In particular, the product can make the desulfurization equipment more than 95% efficient, compared with the use of polypropylene plastic pipe, rubber lined steel pipe and other products increased by 5% to 15%, to improve energy-saving emission reduction effect is very obvious. In addition, through the improvement of the curing molding process and the application of new materials, the product greatly improves the high temperature performance of the product and satisfies the process requirements of 180-200°C in the production process. At present, the company's products have been applied to domestic desulfurization equipment, application effect is good.

Car wax is a traditional car paint care. Car wax is mainly composed of natural wax or synthetic wax, which can increase the brightness by penetrating into the gaps of the paint surface to make the surface smooth. Traditional car waxing is mainly for light protection. Now, with the development of car beauty industry, car waxing has been given a new connotation, that is, the appearance and increasingly extensive application of grinding wax.
