Hakaden packing was developed in 1978 by the German Raschig Group of Companies (now part of the American PMC Global Group). This packing is mainly suitable for the gas purification tower, so it is also called environmental protection ball packing.
CPVC Hakaden packing is a polyvinyl chloride (CPVC) filler, which is mainly used in gas purification devices. Due to its high heat resistance, chemical stability and mechanical strength, it is suitable for handling corrosive gases and liquids. Here are some of the places where CPVC Hakaden filler may be used:
Chemical industry: In the process of chemical production, various corrosive gases and liquids are often produced, such as chlorine. CPVC Hakaden packing is resistant to these corrosive substances and can therefore be used in gas purification plants in the chemical industry. Pharmaceutical industry: In the process of pharmaceutical production, it is often necessary to deal with some corrosive drugs and gases, such as ethanol, acids, alkalis, etc. CPVC Hakaden resins can be used in gas purification units in the pharmaceutical industry to improve drug quality and production. Environmental protection industry: In the process of treating industrial waste gas and wastewater, it is often necessary to use various gas purification devices. CPVC Hakaden packing has excellent corrosion resistance and heat resistance, which can be used in gas purification devices in the environmental protection industry to improve the treatment effect of waste gas and wastewater. Laboratory: In the laboratory, it is often necessary to conduct various chemical experiments, such as gas analysis, chromatography analysis, etc. CPVC Hakayden packing can be used in gas purification devices in laboratories to improve the accuracy and reliability of experimental results.
Compared with other plastic fillers, CPVC Hakaden filler has the following advantages:
1. High heat resistance: The melting temperature of CPVC is 215-235 degrees Celsius, and the heat deflection temperature is 98-106 degrees Celsius, which can maintain good performance in a high-temperature environment. This allows CPVC Hakayden packing to be more stable and reliable when handling high-temperature gases and liquids.
2. Excellent chemical stability: CPVC has excellent corrosion resistance to most chemical media such as acids, alkalis, salts, etc., and can resist the erosion of various corrosive substances. This allows CPVC Hakayden packing to be more durable and reliable when handling corrosive gases and liquids.
3. Better mechanical properties: CPVC has high mechanical strength and elastic modulus, and is not easy to deform, age or embrittlement. This gives CPVC Hakayden packing greater stability and reliability when subjected to pressure, vibration or shock.
Fourth, good processing performance: CPVC is easy to process and form, and can be cut, drilled, turned, welded and other processing operations as needed. This allows CPVC Hakaeden packing to be processed more flexibly and conveniently in the plant manufacturing process.
Fifth, lower cost: compared with other corrosion-resistant materials, such as metal, glass, etc., CPVC is lower.
There are many types of CPVC Hakaden fillers, the common ones are: 25, 38, 50, 76, 90, 100, etc. These models are available in different sizes and sizes for different applications. For example, when dealing with high-temperature gases and liquids, it is necessary to choose CPVC Hakaden fillers with high heat resistance, such as 25, 38, 50 and other models. These types of fillers are able to maintain stable performance in high-temperature environments and have a long service life. For the handling of corrosive gases and liquids, it is necessary to choose CPVC Hakaden packing with excellent chemical stability, such as 76, 90, 100 and other models.
