Prof. Weina, University of New South Wales, Australia? Sahajwara has developed a new method of using waste rubber and plastic for steel production - polymer injection process. Haikou Oil hose It can not only greatly reduce the environmental pollution caused by waste rubber and waste plastics, but also effectively reduce the cost of steel production. Waste rubber and plastic contain a lot of carbon. Waste rubber and plastic are put into the electric arc furnace as substitutes for carbon element. The carbon originally locked in the waste plastic hose will react at ultra-high temperature and burn with coal to become clean fuel, thus reducing greenhouse gas emissions, At the same time, it also alleviates the environmental pollution caused by using them as landfill. The advantage of polymer injection process is that by injecting polymer and coke or anthracite rubber tube mixture, the volume of slag can be increased and the foaming degree can be increased, which can extend the arc length, increase the heat transfer from the arc to steel, reduce the heat loss through the slag and side walls, and thus improve the power efficiency. This reduces power consumption by about 3%. For every 1 ton of steel, about 24% of the cost comes from the cost of electricity. After polymer injection technology is adopted, each furnace of steel is, Oil hose Where can I find it? The average total amount of carbon injected can be reduced by 10%~20%. In addition, the potential price of polymer is lower than that of coke, and the total cost of carbon injection can be saved by 15%~35%.
Common for ventilation duct production Oil hose What should be paid attention to during processing: the galvanized air duct shall not be connected with s-shaped, c-shaped right angle and vertical angle plugs. Clasp type air duct shall not be used for Grade 1 to 5 clean air. The rivet spacing of air duct shall be less than 100 mm. When the air purification level is 1-5, the rivet spacing of air duct shall be less than 65 mm. Before processing the galvanized air duct, use cleaning solution to remove the oil stain and dust on the surface of the plate. The cleaning solution shall be a neutral detergent, which will not damage the board surface, and will not produce dust after drying, so it will not be harmful to human health. Clean the vent pipe with cleaning solution after fabrication. After cleaning, the electric board shall be sealed in time after the white silk cloth cleaning inspection meets the requirements. The inner wall of color coated steel pipe shall be smooth, and the coating shall not be damaged during steel plate processing. The damaged parts shall be coated with epoxy resin.

The sealing materials shall be isobutyl rubber, chloroprene rubber, modified silica gel, etc. The sealing surface of the air duct plate joint shall be located at the positive pressure side of the air duct wall. The production site of galvanized air duct shall be relatively closed, and the production site shall be paved with soft materials that are not easy to produce dust. The galvanized air duct shall have fewer longitudinal joints, glass fiber reinforced plastic ventilation pipes, and no transverse joints. Oil hose Where can I find it? The processing of connecting bolts, nuts, washers and rivets shall be galvanized or other anti-corrosion measures, and blind rivets shall not be used.
What is stainless steel spiral duct? Oil hose Where can I find it? The products are mainly used to connect the air flow between two places and play the role of ventilation. There are three types of galvanized spiral air ducts, stainless steel spiral air ducts and composite spiral air ducts. Here we mainly talk about the stainless steel spiral air duct, and briefly analyze the reason why it is widely used in villas. The so-called stainless steel air duct is strictly a kind of air duct processing technology, also known as spiral seamed thin-walled tube. The best quality is the thin-walled tube with spiral seamed made of metal strips. Because the applied material is metal, it is also called spiral seamed metal tube. It was first used in the military industry of western countries, such as ships, ship ventilation, air conditioning systems, and later used in trains Subway, mine and other civil facilities. By 2000, according to statistics, 95.6% of office buildings, shopping malls and subways in the United States had applied spiral air ducts. In civil residential buildings, 72.5% of central air conditioners use spiral air ducts. Since the mid-1990s, China has introduced this technology into the shipbuilding industry. With the rapid development of China's economy, the use of central air conditioners has increased year by year, and the quality of auxiliary products for exhaust and air supply has been continuously improved. Spiral air ducts have been widely used in some villas. (1) Product standardization: The production of spiral round air duct fittings (pipe fittings and joints) has been highly automated, systematic, and has industrialized quality control. It is well known that the wind resistance of circular duct is much smaller than that of rectangular duct. (2) Easy to install. The installation of spiral air duct significantly reduces the connection points between pipes and minimizes the leakage at the joint of pipe fittings. The typical spiral air duct is 3~6m long, while the typical rectangular air duct is only 1~1.5m long; The connection of two spiral air ducts requires only one pipe connector, while the connection of traditional rectangular air ducts often requires a completely independent double flange system. (3) Usually only small installation space is required: the same production Oil hose The circular pipe with a diameter of 200mm in the installation space can replace 250 × 150mm rectangular pipe. On the premise of not increasing additional installation space, several parallel circular pipes can replace flat rectangular pipes.
Haikou Oil hose The break of the sandblasting hose usually refers to the appearance and change of the crack of the sandblasting hose. The sandblasting hose has one or more cracks, but the cracks are neat. Another is that the internal bending cracks at the crack of the sandblasting hose are neat. The causes of different errors are different, and the treatment methods are also different. Therefore, in the process of using or protecting the sandblasting hose, the sandblasting hose should not be subject to changing torque. When installing the sandblasting hose, try to keep the axis of the two joints on the same plane to avoid twisting the sandblasting hose in use. Therefore, be careful with the application, and try not to make the sandblasting hose change excessively to avoid consumption. Sand blasting hose plays a very important role in the industry. Its inner rubber layer is added with carbon black, which can effectively eliminate static electricity and directly contact with compressed air and abrasives. The requirement for wear resistance is quite high. Once worn through, the reinforcement layer will be exposed, and the sand blasting hose will burst. The reinforcing layer of sandblasting hose is a pressure resistant layer, so production Oil hose The material and layout of the reinforcement layer directly determine the pressure rating of the sandblasting hose. There are two common enhancement layers: cloth clip enhancement layer and surround enhancement layer. The sand blasting hose with an inner diameter of 50mm or more is mostly used in the construction occasions where the sand blasting pipe needs to be extended to reduce the pressure loss in the sand blasting hose and ensure the normal operation of shot blasting.
“ production Oil hose What are the applications in engineering transformation? " In this issue, we will explain this problem for you. Those who have consulted this problem will come to see it: First, we should consider the water supply and drainage of all water related equipment, such as wells, pumps, etc., their location, installation method and temperature, including galvanized air ducts. 2、 It is very important to consider galvanized air duct in advance to avoid temporary replacement of galvanized air duct materials. 3、 After the location of the machine tool is determined, the drainage outlet can be considered to be arranged underground, which is not only convenient but also durable. 4、 After river reconstruction, there should be a suppression test, but now many construction teams do not suppress the test. It is usually said that it is not important, that there is water and pressure in the galvanized air duct, and so on. Try to be present to suppress the test. 5. If the installation is completed, pay attention to the inspection of the workshop, water pump room and FRPP drain. If the drainage system is slow, the installation program should be able to open the installation. Water outlets should be protected, especially during civil engineering construction, Oil hose Where can I find it? It may cause soil loss and blockage. I believe that you have a better understanding of this information, and we will continue to improve the galvanized air duct to make it more widely used.
