PVC steel wire reinforced pipe is also a PVC steel wire reinforced hose that uses steel wire reinforcement. The embedded spiral steel wire is used as the reinforcement layer, so the product has both rigidity and flexibility, that is, it has both satisfying mechanical properties and rigidity, and excellent flexibility. The reinforced pipe of latex fiber is PVC hose embedded with steel wire framework. The inner and outer tube walls are clear, lubricated, free of bubbles, and the fluid transportation is clearly visible. Silicone fiber tube is resistant to low concentration of acid and alkali, high elasticity, not easy to age, and has a long service life. Resistant to high pressure and can be kept intact under high pressure and vacuum. PVC steel wire pipe is made of new PVC reinforced materials, and has made great progress in compressive strength and hardness. The main production method of silica gel steel wire pipe is multiple production method. The main types of steel wire pipe in shopping malls include high pressure steel wire pipe, low pressure steel wire pipe, steel wire skeleton pipe and Tongming steel wire pipe. The application methods are different in different environments. The new PVC steel wire pipe is the most widely used commodity today. Oxygen band Price After use, it will not be the same as the metal pipe, which is easy to deform and leak. What advantages does the PVC fiber reinforced pipe have.

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. city in Hunan 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%.

The so-called acid and alkali resistant rubber hose is the rubber hose used to transport acid and alkali solutions, which can be divided into wear-resisting Oxygen band , acid and alkali resistant cloth clip hose, etc; In actual production, using a certain proportion of recycled rubber for acid and alkali resistant rubber hose can not only reduce the cost of raw materials, but also improve the aging resistance of rubber compound, thus extending the service performance and service life of acid and alkali resistant rubber hose. However, if you want to significantly improve the aging resistance of acid and alkali resistant hose, it is impossible to rely solely on recycled rubber, and rubber antioxidant is essential. What anti-aging can be used in acid and alkali resistant hose? 1. Antioxidant A: Antioxidant A, namely, antioxidant A, is in the form of yellowish brown to purple crystal blocks at room temperature. It is a universal antioxidant, which has good resistance to heat, oxygen, flexion, weather and fatigue aging. It also has a certain inhibitory effect on harmful metals. It is easy to disperse in the rubber compound, and has no obvious impact on the processing performance of the rubber compound and the physical and mechanical strength of the vulcanizate, It is the preferred antioxidant product in the production of acid and alkali resistant hose. It can also be used as a stabilizer in the acid and alkali resistant hose containing styrene butadiene rubber, which can significantly delay the aging time of acid and alkali resistant hose. 2. Antioxidant D: antioxidant D, namely N-phenyl - β－ Naphthylamine (D) is a kind of heat aging resistance commonly used in the production of rubber products, Oxygen band Price Anti aging agent resistant to fatigue aging; Due to the poor heat resistance of the acid and alkali resistant hose, the use of a small amount of antioxidant D in the protection system can improve the heat aging resistance of the rubber compound, thereby improving the heat resistance of the acid and alkali resistant hose, expanding the use temperature range, and extending the use time.

wear-resisting Oxygen band 1. During the molding of rubber products, the cohesive force of the elastomer cannot be eliminated due to the large pressure pressing. During the molding and mold release, extremely unstable shrinkage (the shrinkage rate of rubber varies due to different rubber types) often occurs. It must take a period of time before it can be gentle and stable. Therefore, at the beginning of the design of a rubber product, no matter the formula or the mold, it is necessary to carefully calculate the matching. If not, it is easy to cause dimensional instability of the product, resulting in low product quality. 2. Rubber belongs to thermosetting elastomer, while plastic belongs to thermosetting elastomer. Due to different sulfide types, the temperature range of rubber molding and curing is quite different, even affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be properly adjusted at any time. If not, there may be differences in product quality. 3. The rubber product is the rubber mixture made from rubber raw materials after mixing in the internal mixer as the raw material. The formula is designed according to the characteristics of the required rubber products during mixing, and the required product hardness is determined. The product is molded by the rubber plate vulcanizer. After the product is formed, flash processing shall be carried out to make the product surface smooth without burrs. 4. The aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomenon that the performance and structure of rubber and products are changed due to the combined effect of internal and external factors in the process of processing, storage and use, thus losing their use value. Oxygen band Price It is characterized by cracking, tackiness, hardening, softening, chalking, discoloration, mildew, etc. The following conditions shall be met when the ball mill uses the rubber lining plate: 1. The hardness of the ground material. The iron base alloy is similar to the rubber lining plate for materials below medium hardness, and the rubber lining plate is superior for materials above medium hardness. 2. The temperature of rubber lining plate is generally 70 ℃ - 90 ℃, and it can reach 110-130 ℃ under special circumstances. The temperature should be lower during dry grinding. 3. Feed size. Generally, the ball mill shall be more than 20-25mm; For the autogenous mill, the feeding particle size can be larger because no steel ball is added.

How to install correctly city in Hunan Oxygen band ？ In the fire smoke exhaust pipe system, the airport and air valve must use non fuel, and the thickness of citizen flue and galvanized ventilation pipe should be improperly used. The high-pressure system should be selected according to the national code GB50243. When the fire smoke exhaust fan is installed on the roof, certain maintenance measures should be taken. The exposed power line must be threaded through the conduit, and the conduit material should be combined with the metal hose or Capelli and duck neck equipment to make it curved. The fire fighting system and equipment lines must be fixed with special clamps to avoid falling. Stainless steel air duct and ventilation equipment shall be made of three fabric flame retardant materials with soft connection. It is suggested that the length should be 15-30cm, and the electrical interpenetration should be completed. Bolts require the same length. The three main bodies should be grounded, ventilation equipment, and equipment and devices between dynamic loads should be equipped with shock absorption measures. When Oxygen band Price Box type pipe fittings should not be used for changing direction, variable diameter, branch road, or junction, but the wind speed of box section should not exceed 1.5m/s for air distribution and static pressure box when necessary; It is advisable to have 5-10 times the pipe diameter between conduit pipes. The length of expandable metal pipes or non-metallic soft links should not exceed 2 meters. There should be no disintegration and dead corners. During the installation process, when the length of pipe elbows and straight pipes exceeds 20 meters, add anti impact frame open room exhaust fans and add or subtract supports.

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 wear-resisting 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.
