production Oxygen band The thickness of the seaming plate shall be within the regular range of products of various specifications. If it is less than the thickness, cracks, wrinkles and other defects are likely to occur during seaming; If it is larger than the large thickness, as the square of the plate thickness is proportional, the bending force will significantly increase, which will cause abnormal damage to the forming roller, overloading of the transmission system, and stuffiness. In dust removal system: galvanized air duct can be used for collection and transportation of dust removal device. In the oil smoke exhaust system: there are a lot of oil smoke in restaurants, restaurants and hotel kitchens, which need to be discharged. The galvanized air duct is suitable, strong, economical and practical. In air conditioning system: galvanized air duct can be pasted with thermal insulation materials inside, and the surface is beautiful. In bulk material transportation: pneumatic transportation system, some finer and looser material particles can be transported by galvanized air ducts, with low cost and good effect. In the ventilation system: supply fresh air and exhaust gas, exhaust harmful gas outdoors, and send outdoor fresh air indoors. The strength of stainless steel plate shall be higher than that of ordinary steel plate. Before seaming with stainless steel plate, forming test shall be carried out first to avoid overloading the equipment and causing excessive wear or mechanical trouble. Due to the poor plasticity of the aluminum plate, it is easy to crack during the forming of the seaming. The forming test should also be carried out before construction. At the same time, because the aluminum plate is lack of elasticity, the aluminum plate air duct cannot be subject to snap seaming. After the zinc coating of galvanized air duct is passivated, dyed or coated with light protection agent, Oxygen band Price It can obviously improve its protection and decoration. The fireproof function of galvanized air duct is mainly reflected in that it is incombustible, but one thing needs to be noted is that whether its insulation layer is burned depends on the material. We suggest that the galvanized air duct should be made of incombustible insulation materials such as centrifugal glass wool.
In the shipbuilding industry, radio industry, electrical industry, telecommunications industry, instrument industry, aviation industry, medical industry, etc., we often see acid and alkali resistant hose, then what is Lanzhou Oxygen band What about? If you want to know more, please read down! Acid and alkali resistant silicone hose is a kind of pipe specially used for power equipment, which uses acid and alkali resistant silica gel as the main raw material and tightly wraps the pipe wall with electrical grade polyethylene spiral wire. Due to the chemical inertia of acid and alkali resistant silica gel, this kind of pipe has good acid and alkali resistance performance and electrical performance, and is commonly used in the production of wires, cables and lead wires in extreme acid and alkali environments. Also called: acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose.

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. Lanzhou Oxygen band 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, Oxygen band Price 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%.
What is stainless steel spiral duct? Oxygen band Price 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 Oxygen band 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.

We are all denominators. Why treat ourselves as molecules. But I think we Oxygen band Price The mass of is absolutely the molecule in the same industry. From raw materials, the general manager is responsible for the purchase of raw materials. Raw materials can only enter the factory after passing the inspection. Because it is the boss's own purchase and inspection, there is no buyer to take kickback, which increases the cost of raw materials and reduces the quality of raw materials. Speaking of the manufacturer's production process, it is difficult to find the second advanced mixer equipment among the new sand pumping hose manufacturers in 2019. It ensures that our glue is more uniform. This ensures the quality of our sand pumping hose. About 70% of sand pumping hose is manual work, and the production technology experience of workshop workers largely determines the quality of our sand pumping hose. 70% of our workshop workers have more than 7 years of production production Oxygen band Experience. Select rubber hose Wang Xueyan purchases sand pumping rubber hose, which is more insurance than insurance company. Our goal is to become a member of the hose industry with excellent sand pumping hose quality. Place an order yesterday and deliver it today. At this speed, it is hard to find a second sand pumping hose in the industry. Life doesn't treat us kindly because we are women. But we should treat our own lives well and try to sell sand pumping hoses. As an excellent salesman, will you also receive an inquiry like chicken ribs. When I was just doing business, I received a 3 page quotation, and I patiently sorted it out for about 2 days. Finally, there was no news. Now I have been doing business for more than 10 years. Sometimes I can accurately judge the order rate of this order simply by looking at the inquiry list. The real heart of the words lies in the customers who make good deals.
