Based on the connection and com bination of superfine fibers of different diameters , those air filter materials , which can be observed with distinct morphologies under SEM, hold different filtration properties During the production process, Zisun needs to control the raw material techno logy and stabilize large - scale production at the nanoscale . T he comprehensive technology is extremely high. 1.1 Glass Fiber Filter Paper Fine micro glass fiber is the main raw material of glass fiber filter media which is produce by Wet - laid process. Usua lly, the thickness of this glass fiber filter media is 0.3mm. Compared with other filter materials made of animal and plant fibers, synthetic fibers and activated carbon, it has the characteristics of large dust holding capacity, high filtration efficiency and uniform fiber distribution. As an ideal clean air filter material, it is a core component of clean air equipment. Glass fiber filter media is widely used in advanced manufacturing, biomedicine, animal husbandry and other fields that require high air c leanliness. 图片包含 游戏机, 建筑, 窗帘 描述已自动生成 ( Fig of Glass Fiber Filter Media Product ) 躺在地上 描述已自动生成 ( High - performance glass fiber filter media ， Zoom in 488 times ) 1.2 High - efficiency PTFE Membrane PTFE is the abbreviation of polytetrafluoro ethylene. It has a molecular weight, which is generally million s, either hundreds of thousands to the lowest or more than ten million to the highest. T he global industry continues to explore and develop new filter materials in recent years. PTFE membrane has attracted widespread attention in the industry for its unique molecular structure and superior filtration performance. Bulking and stretching the PTFE molecule in two directions, here come a high - efficiency PTFE membrane containing a large number of mi cropores and high porosity. It combines the advantages of more stable chemical properties, more uniform fiber distribution, higher filtration performance, and lower resistance and become an irreplaceable new high - end filter material in some special applica tion fields. After several years of R&D, Zisun owning unique technical advantages, is one of the few companies in the world that can stably produce high - performance PTFE membranes in large quantities. Due to ultra - high efficiency and ultra - low resistance, PTFE Filters shows low system resistance, low energy consumption and stable chemical properties which are widely used in panels, semiconductors, medicine, household appliances and other industries. It can also be matched with other filter materials and equ ipment to provide optimal " Clean Air " solutions for different scenarios 1.3 Low - resistance Melt - blown Media Low - resistance melt - blown media is produced by melt - blown method, in which polymer electret masterbatches such as polypropylene are blown through th e polymer melt at high temperature and high speed, so that the fibers are rapidly stretched, and the fibers are then cured on the curtain device to form melt - blown filter media. The filtration performance is influenced by the fineness of fiber diameter and electrostatic adsorption effect. The low - resistance melt - blown media has a unique capillary structure and the filtration efficiency can reach HEPA level, which can be used in air purifiers, fresh air systems, individual protection and other fields. 1.4 Mi cro Electrostatic Filtration Media Micro electrostatic filtration media uses a strong electric field with a unique dielectric material as the carrier to sterilize and adsorb fine particles (blocking aerosols) to achieve air disinfection and purification te chnology. The dust collection module is made of non - metallic materials (polymer) and graphene materials as carriers, and is combined with driving circuits, which overcomes the disadvantages of traditional metal electrostatic generation of ozone, lightens a rc discharge, with powerful function of efficient sterilization, adsorption of particles as small as 0.01um. 1.5 Chemical Filtration Media Chemical filtration media is used for the treatment of nano - scale molecular compound gases such as VOCs, AICD, BASE, etc., and extremely low concentrations of airborne molecular pollutants at the ppb level one billionth concentration) or even ppt level (one trillionth concentration) . Z isun has made a breakthrough in the bottleneck of airborne molecular pollutant control technology through in - depth principle research and application practice . W e provided chemical filtration equipment for Hefei Jinghe Semiconductor Phase II project in the semiconductor field, Nanjing China Electronics Panda Ligh ting, KinWong Electronics and CSCEC Electronics in the panel field, Nine Dragons Paper, Jinhai Pulp & Paper and other paper companies, as well as the Bank of China and China Settlement Center data room projects to provide chemical filtration equipment to e nsure safe production in many industries. With the national policy’s emphasis on “high - quality development” and “high - quality life”, Zisun increasingly recognize that CLEAN AIR materials and technology play an important role in this area of improving the work efficiency of people and equipment, minimizing energy consumption, benefiting human health and environmental safety. Zisun has been cultivating the technology of clean air materials for many years, actively excavating the properties of materials, and striving to expand new materials and new applications. 2. Technical Mechanism of Zisun Clean Air Materials The materials, equipment and solution of Zisun Clean Air portfolio is capable to protect human health, high - end manufacturing production processes, a nd the environment from the harm the air pollutants. Air pollutants components can be subdivided into particulate matter (PM ) and airborne molecules (AM). As shown in the figure, different particulate pollutants in the air have different sizes, ranging from 0.1um to 500um. 图示, 文本 描述已自动生成 (F ig from Visual Capitalist) Common sources of particulate pollutants can be divided into four categories: . . Natural source: soil dust, pollen, spore, bacteria. . . Fixed Manmade source: fuel combustion (e.g., electricity generation, metallurgy, petroleum Industry, chemical industry, textile industry, heating supply, various industrial process, cookin g etc. ） . . Moved Manmade source: Exhaust gas emitted into the atmosphere when various vehicles consume fossil fuel. 图示 描述已自动生成 Different production and living environments have different requirements for clean air. From high - end manufacturing to thousands of househo lds, Zisun Clean Air materials have important applications scenarios. In the semiconductor field, for example, the production environment requires extremely high cleanliness, and the airborne particulate contaminants have a significant impact on the proces s yield, performance and reliability of products. A rule of thumb is that the particle size should be less than 1/10 times the size of the smallest feature on the device, i.e., a particle with a diameter of 0.03μm will damage a feature with a line width of 0.3μm. Therefore, controlling particulate contamination in the semiconductor manufacture process is of great significance to the economics of the production process. For the manufacturing process of panel field, the particles will adhere to the surface of the substrate. In addition, the electrostatic attraction, Brownian motion, thermal motion, photosensitive phenomena, and colloidal micelle effects may cause particle adhesion. The rule of thumb is that the particle size must be less than half of the minim um device feature size, particles larger than this size can cause fatal defects, such as a 2 μm feature size cannot touch particles larger than 1 μm in size. For the public’s daily life related to indoor spaces such as homes, schools, offices, hospitals, e tc., the state, industry, and the public are gradually emphasizing, paying attention, and popularizing the effects of airborne particulate pollutants on health. Airborne particulate matter can enter the human body through respiratory, digestion and skin, a nd has multiple negative impacts on human health.
