\nIndustry is the most important application scenario for high-temperature resistant high-efficiency filters with separators, especially for production processes where “particle contamination needs to be avoided in high-temperature process links”, which directly affects the product qualification rate.
\n1. Electronics and semiconductor manufacturing
\nSpecific scenarios: High-temperature diffusion, oxidation, and sintering processes of semiconductor chips; High-temperature annealing and evaporation processes for liquid crystal panels (LCD\/OLED); High-temperature packaging of electronic components (such as capacitors and resistors).
\nCore function: Filter the air entering the high-temperature process chamber to remove dust, metal particles, and volatile organic compounds (VOCs) pyrolysis products smaller than 0.3\u03bcm, preventing these impurities from adhering to the surface of chips or components, which could lead to circuit short circuits, poor display, and other defects.
\nTypical requirements: The filtration efficiency should reach H14-U15 grade (ultra-high efficiency), and the temperature resistance grade is mostly 180-250\u2103 (to match the continuous high-temperature requirements of the process).
\n2. Automobile and auto parts manufacturing
\nSpecific scenarios: High-temperature electrophoretic painting of car bodies, drying rooms; High-temperature casting and heat treatment of engine blocks; High-temperature forming and coating of automotive glass.
\nCore function: Purify the intake air of the drying room and heat treatment furnace, prevent dust and fibers in the air from adhering to the uncured paint surface or the surface of high-temperature components, and avoid quality problems such as “orange peel texture” and “pinholes”. At the same time, it filters out metal debris in the exhaust to reduce pollution to the environment.
\nTypical requirements: Temperature resistance grade 180-300\u2103 (the temperature in the drying room is usually 120-220\u2103, and it can reach over 250\u2103 in the casting process), and filtration efficiency grade H13 can meet the standards of most automotive manufacturers.
\n3. Chemical Engineering and New Materials Manufacturing
\nSpecific scenarios: High-temperature extrusion and vulcanization of polymer materials (such as plastics and rubber); High-temperature sintering of special ceramics (such as alumina ceramics) High-temperature calcination of cathode materials for lithium batteries (such as ternary materials).
\nCore function: On the one hand, it filters the air impurities that enter during the raw material reaction process to prevent them from affecting the purity of the material (for example, the purity of lithium battery materials is directly related to the battery capacity); On the other hand, filter out the dust in the high-temperature exhaust gas discharged to prevent environmental pollution or clogging of subsequent equipment.
\nTypical requirements: Temperature resistance grade 200-350\u2103 (ceramic sintering temperature can reach over 300\u2103), and stainless steel frames are required for some corrosive working conditions.
\n4. Metallurgy and Metal Processing
\nSpecific scenarios: High-temperature annealing and quenching of special steel materials; High-temperature smelting and purification of precious metals (such as gold and silver) High-temperature atomization preparation of metal powders.
\nCore function: Purify the intake air of the high-temperature furnace to prevent oxygen, nitrogen and dust in the air from reacting with metals, which could lead to metal oxidation and inclusions, affecting their mechanical properties (such as the toughness of steel) or purity (for precious metals, the purity needs to be above 99.99%).
\nTypical requirements: Temperature resistance grade 300-500\u2103 (for some smelting processes, the temperature exceeds 400\u2103), and high-temperature resistant metal fiber filter materials or ceramic fiber filter materials must be used.
\nIi. Medical and biosafety fields: Balancing high-temperature disinfection and purification protection
\nThe application in this field focuses on “air purification in high-temperature disinfection scenarios”, which not only needs to meet the high-temperature requirements of disinfection but also prevent the spread or contamination of microorganisms.

\nSpecific scenario: Auxiliary air purification for high-temperature sterilization cabinets (such as pulsating vacuum sterilization cabinets); High-temperature exhaust air filtration for infectious disease wards and biosafety laboratories; Air purification for dental high-temperature porcelain furnaces.
\nCore function: When the sterilization cabinet is in operation, it needs to filter the incoming air to prevent impurities from affecting the sterilization effect. The exhaust air from the infectious disease ward, after being filtered at high temperatures, can inactivate some viruses (such as the novel coronavirus and influenza virus), preventing aerosol spread. The purification of the porcelain oven can prevent dust from affecting the accuracy of dentures.
\nTypical requirements: Temperature resistance grade 180-250\u2103 (the temperature of a sterilization cabinet is usually 134\u2103, but a safety margin must be reserved), filtration efficiency H13-H14 grade, and it must meet medical-grade biological safety (no shedding).
\n2. Biopharmaceuticals and vaccine production
\nSpecific scenario: High-temperature inactivation process of vaccines; Purification of the intake air of high-temperature fermentation tanks for biological agents (such as antibiotics); High-temperature forming and cleaning treatment of pharmaceutical glass.
\nCore function: Filter the air entering the fermentation tank, remove miscellaneous bacteria and dust, and prevent contamination of the bacterial strains. The air purification in the high-temperature inactivation process can prevent external impurities from mixing with the vaccine, ensuring the safety of the drug.
\nTypical requirements: Comply with GMP (Good Manufacturing Practice) standards, withstand temperatures around 200\u2103, have a filtration efficiency of H14 grade, and the filter material must pass biocompatibility tests.
\nIii. Aerospace and military Industry: Adapted to extreme high temperatures and high reliability requirements
\nThis field has extremely high requirements for the “high-temperature resistance limit” and “structural stability” of filters, and they need to be adapted to the purification needs under extreme working conditions.
