dust collector filter bag technology is widely used worldwide for controlling industrial smoke and dust to improve air quality and protect the environment. Different countries and regions have different technical requirements for filter media used in dust collector filter bag, but generally pay attention to the performance, durability, environmental protection standards, and adaptability to specific industrial applications.
Global standards and technical requirements: The bag filtration systems and filter bags provided by Gray Whale Technology Company follow global standards while meeting local regulatory requirements. These products are manufactured at multiple locations around the world to meet the needs of different applications. – The global technical requirements for filter media used in dust collector filter bag usually include regulations on the naming, classification, requirements, test methods, inspection rules, packaging, marking, storage, and transportation of filter media. These standards apply to various types and specifications of filter media for baghouse dust collectors.
Chinese standards: – “Technical Requirements for Filter Media for dust collector filter bag” (T/CAEPI 21―2019) in China is a group standard formulated by the China Association of Environmental Protection Industry. It covers the definition, terminology, technical requirements, detection methods, inspection rules, product marking, packaging, transportation, and storage of filter media. This standard not only is compatible with international standards but also adds test methods for some important filter media-related indicators not mentioned in domestic and foreign standards. – This standard proposes the continuous test temperature and instantaneous test temperature of filter media, as well as the test requirements for breaking strength retention rate and thermal shrinkage rate at these temperatures. In addition, it also stipulates special requirements such as abrasion resistance, folding resistance, film adhesion strength, and surface layer peel strength of filter media.
International standards: – International standards such as ISO 11057―2011 and ISO 16891―2016 involve test methods for filter media filtration performance and durability. These standards provide a basis for testing and evaluating the performance of filter media for dust collector filter bag globally.
Material selection: – Selecting the appropriate filter media material is the key to achieving effective industrial filtration. Filter media materials such as polyester, polypropylene, and nylon all have their specific advantages and considerations. Understanding the specific needs of the application, including temperature requirements, chemical compatibility, and the desired micron level, is crucial for making informed decisions.
In conclusion, although there are differences in the technical requirements for filter media used in dust collector filter bag around the world, the common goal is to ensure the performance and durability of filter media to improve the control efficiency of industrial emissions and protect the environment and human health. The formulation of standards in this field in China not only reflects the progress of domestic technology but also provides convenience for participation in the international market.
