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 CiH Sandblasting hose 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. Features: 1. High temperature resistance (250-300 ℃) and low temperature resistance (- 40-60 ℃); 2. Good acid and alkali resistance. Physiologically stable, able to withstand repeated harsh and disinfection conditions, resistant to ozone aging, light aging, weather aging and ultraviolet radiation. 3. Small resilience and permanent deformation (no more than 50% at 200 ℃ for 48 hours), breakdown voltage (20-25KV/mm), ozone resistance and UV resistance. Sandblasting hose Where can I find it? Radiation resistance and other characteristics, 4. Good electrical performance, small change when exposed to moisture, water or temperature rise, even if the silica generated by short circuit combustion is still an insulator, which ensures that electrical equipment continues to work, so it is most suitable for making wires, cables and lead wires.

What is stainless steel spiral duct? Sandblasting 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 high quality Sandblasting 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.

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 high quality Sandblasting hose , 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, Sandblasting hose Where can I find it? 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.
