Technical analysis of high temperature and mildew resistant air filter materials
Human daily life and production activities will produce harmful particles, which are scattered in the air or water, and have a serious impact on human health and normal production and life. Dust and smoke will destroy the working environment and affect people's health. The mixing of dust and smoke will reduce the service life of the instrument and the quality of industrial raw materials. With the development of China's economy and the issue of environmental pollution on the agenda, China has become one of the fastest growing and largest filter material markets in the world. Filtration is an operation that separates and captures particulate matter dispersed in gases and liquids. However, there is still a lack of air filter materials with high temperature resistance and mildew resistance on the market to meet people's needs. Contents of the utility model The purpose of the utility model is to provide a high temperature resistant and mildew proof air filter material to solve the problems raised in the above background technology. For achieving the above purpose, the utility model provides the following technical solutions: a high temperature resistant and mildew proof air filter material, comprising a non-woven protective layer, an aromatic polyamide fiber layer, a honeycomb activated carbon filter layer, an ultra-fine glass fiber layer and Anti-mildew composition layer, the non-woven protective layer is arranged on the outermost layer of the entire air filter material, the inside of the non-woven protective layer is provided with an aromatic polyamide fiber layer, and the honeycomb activated carbon filter layer is wrapped Inside the aramid fiber layer, an ultra-fine glass fiber layer is provided inside the aramid fiber layer, and the anti-mold composition layer is wrapped inside the ultra-fine glass fiber layer. Preferably, the diameter of the filter particles of the non-woven protective layer is larger than the diameter of the filter particles of the ultra-fine glass fiber layer. Preferably, the thickness of the honeycomb activated carbon filter layer is 0.3mm. Preferably, the antifungal composition layer is composed of a antifungal agent layer and an adhesive resin layer, and the antifungal agent layer is pasted on the adhesive resin layer. Compared with the prior art, the beneficial effects of the present utility model are: the air filter material with high temperature resistance and mildew resistance has a simple and reasonable structure, is economical and practical, and the non-woven protective layer can not only protect the entire air filter material, but also have a larger air filter material. The honeycomb activated carbon filter layer has a large adsorption capacity for harmful gases and dust such as odor, peculiar smell, benzene, methanol, etc. The aromatic polyamide fiber layer has a good material for high temperature resistance and corrosion resistance, and the ultra-fine glass fiber layer It can capture 0.1-0.3 micron dust particles and has a strong dustproof effect. The anti-mold composition layer can prevent the air filter material from becoming moldy, thereby affecting normal use. Brief Description of the Drawings Fig. 1 is a schematic structural diagram of the utility model; Fig. 2 is a structural schematic diagram of the anti-mold composition layer of the utility model. Among the figure: 1, non-woven protective layer, 2, aromatic polyamide fiber layer, 3, honeycomb activated carbon filter layer, 4, ultra-fine glass fiber layer, 5, anti-mildew composition layer, 51, anti-mildew agent layer , 52, adhesive resin layer.

The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
