PTFE ventilation membrane production equipment is also called polytetrafluoroethylene film production line. There are many types of PTFE permeable membranes produced, and the corresponding application areas are also different. Here, it is like everyone recommending Suzhou Leman nano oil-resistant SH-560N to achieve the PTFE film level 6 oil-proof without changing any feel.
1. PTFE air filter membrane
PTFE filter membrane is a unique node, smooth node, smooth surface, chemical resistance, breathable and breathable, large breathability, flame retardant, flame retardant, flame retardant, flame retardant, and flame retardant, and flame retardant, flame retardant, and flame retardant. Products made of high temperature resistance, anti -acid alkali, non -toxic and other characteristics. The filtering efficiency made by the membrane is high, which can reach 99.99%, nearly zero emissions; the operation resistance is low and the filtration speed is fast; the service life is long, which can be reused to reduce the operating cost. It is mainly used in chemical, steel, metallurgy, charcoal black, power generation, cement, waste incineration and other industrial melting furnaces. Polytetrafluoroethylene filter membrane, this membrane pore can be controlled between 0.2 and 15 μm, and the gap rate can reach more than 85%.
Summary:
1: The surface is smooth, easy to clear ash, and can be blown.
2: Energy saving and consumption reduction, reducing operating costs.
3: High temperature resistance, strong acid and alkali, wide application range.
4: High filtration efficiency and long service life.
2. PTFE clothing film
The PTFE clothing film is a micropore film made of polytrafluoroethylene resin as the raw material, which is stretched by a two -way two -way. Widely used in special clothing, fire, army, public security, medical care, anti -biochemicals and other special clothing, as well as shoe, gloves, sleeping bags, tents, etc. The pore formation characteristics of polytetrafluoroethylene plastic resin are made of micropores made of two -way stretching method. The surface of the membrane can reach more than one billion micropores per square centimeter, and each micro-hole diameter (0.1 μm-0.5 μm) is hundreds of times smaller than the diameter of the water molecule (20 μm-100 μm), which is higher than the water vapor molecules (0.0003 μm-0.000444 μm) is tens of thousands of times, so that water vapor can pass, and water droplets cannot pass. Using this microporous structure can achieve excellent waterproof and humidity function.
The micro-hole diameter of the waterproof performance PTFE film is 1/5000-1/20000 of the diameter of water drops, so even the smallest raindrops cannot pass. The surface of the PTFE can be low, and the water droplets cannot be spread on the film, preventing the water droplets from passing through.
The pore rate of PTFE’s clothing film is as high as 80%, the average pore diameter is 0.2um, and the micropore diameter is 700 times greater than the water steam molecule. The water steam molecules can pass freely.
During the stretching process of windproof performance, the PTFE film forms a micropore structure connected to countless micro -fiber connections. The pores are formed between the microfiber, and the pores are connected to each other to form a unique network structure. The wind cannot pass directly, and the direction of the direction will be changed when it encounters a barrier, which effectively prevents the infiltration of the air, so it has excellent windproof performance.
The warmth performance PTFE clothing film has excellent humidity performance. It can timely transmit the steam discharged from the human body to the micro -climate in time, prevent water steam from being condensed into liquid water, and reduce the possibility of water transmission heat. Although the surface of the film is densely micro -holes, the wind cannot penetrate, which effectively prevents air flow.
Anti -nuclear and biochemical performance PTFE film pores are small (average pore diameter 0.2um), which blocks the penetration of some toxic gases or gas solids. The low surface can prevent the penetration of some toxic liquids. Apply a material with high porosity water steam on one side of the film to achieve the selective penetration of water steam and achieve the purpose of fully protection.
3. PTFE air purification film (sterilization film)
The air purification film is based on polytetrafluoroethylene as the raw material. After pushing, pressure, and two -way stretching, a thin -hole film is formed. The pore diameter is small (0.2-1.5um), which is evenly distributed and the pore rate is large (more than 95%). This thin film is covered with special processes on various fabrics and substrates, becoming a new type of filter material. While maintaining air circulation, while keeping air circulation， All dust particles including bacteria can be filtered to achieve the purpose of purifying and ventilation. It is widely used in pharmaceutical, biochemical, microelectronics, and laboratory consumables.
In the application of air purification film, the surface of the PTFE film is specially processed to make it have powerful bacterial resistance and anti -pollution capabilities. A layer of nanocarbulin resistant agent is prepared on the surface of the PTFE film through electrochemical or chemical methods. These bacterial resistant agents can well destroy the bacterial cell wall in the air, thereby achieving the effect of removing the bacteria. Secondly, the micro -pores of the PTFE film can adsorb and store harmful substances in the air, such as PM2.5 particles, harmful gases, etc., thereby improving the air quality.
PTFE air purification film has been widely used in various air purification equipment due to its excellent air filtration performance.
1. Air purifier: In the air purifier, the PTFE air purification film is used as a filter, which can remove particulate matter in the air, such as PM2.5, virus, and small bacteria.
2. Fresh air system: In the fresh air system, it is used to filter the atmospheric air introduced outdoors, remove the harmful substances, and ensure the cleaning and health of indoor air.
3. Air conditioning and ventilation system: In the air conditioner and ventilation system, the breeding of the bacteria and mold can be prevented, and the air is fresh and comfortable.
4, PTFE hydrophilic film
The PTFE liquid filter membrane has the characteristics of surface filtering mechanism and high pores, and has a high flux that is difficult to achieve by other filter membranes. For high -temperature liquid filtration, it has excellent biological safety, chemical inertia, low adsorption and high temperature resistance. Pore diameter 0.2um, large, high, high strength, and high temperature do not fall off. It is suitable for filtration of strong acid and strong alkaline solution, sterilization and filtration of medicinal solution terminals, high -temperature liquid filtration, water treatment and other filter materials that cannot be competent.
PTFE filter membranes can be divided into two types: hydrophilicity and hydrophobicity according to their surface treatment methods. The main differences between them:
Hydrophilicity: It has affinity for water and polar liquids, which is easy to absorb water molecules and substances containing polarity groups. After the surface of the PTFE filter membrane is treated with hydrophilicity, its coating has obvious glass transformation temperature (TG), the contact angle is less than 90 degrees, and can be in contact with water molecules.
Hydividity: Compared to water and polar liquids, it has strong exclusion force. The wavedrops are not easy to adhere to form spherical. After the surface of the PTFE filter membrane is treated with hydrophobic treatment, its coating has a high glass transformation temperature (TG), and the contact angle is greater than 90 degrees. Hydrophobic performance.
In terms of application
A hydrophilic PTFE filter membrane is usually used in the field of water filtration liquid, such as water treatment, biopharmaceuticals and other fields. Hydrophobic PTFE filter membrane is suitable for filtering organic solvents, oils, chemical reagents and other non -polar liquids, such as chemical and petrochemical fields, such as chemical industry, petrochemical and other fields
