The strength and chemical resistance of the filter media are increased

After impregnation, the strength and chemical resistance of the filter media are increased, and the air permeability is reduced. PTFE fiber At present, under some relatively complex high temperature conditions, the service life of pure PPS or aramid fiber is affected, such as waste incineration, dust removal from power plants, and cement dust removal. PTFE emulsion is the most used for glass fiber filter media, because glass fiber has no cohesive force. 


PTFE sewing thread PTFE sewing thread has high strength and good chemical resistance.1. 3. 2. Now many customers use PTFE sewing thread (glass fiber bag, PPS bag, Aramid bags, P84 bags). % PTFE fiber below. PTFE emulsion PTFE emulsion impregnation is also a post-treatment process for high-temperature filter media. 

PTFE base fabric The PTFE base cloth is woven from PTFE filaments, and its main function is to enhance the strength and chemical resistance of the filter bag, and the purpose is to increase the service life of the filter bag; the combination of PTFE base cloth + PPS surface layer is widely used in power plant dust removal. 

At present, many filter material manufacturers have used automatic sewing machines, and only PTFE sewing thread is almost endless. PTFE membrane High-temperature filter materials often add a finishing process in special working conditions, that is, the filter material is treated with PTFE coating, the purpose is to resist condensation, easy to clean dust, and corrosion resistance; currently polyester, glass fiber, PTFE Fusing Belts Manufacturers PPS, aramid And P84 filter media are both useful. Customers often add 50% to ensure the service life of more than 3 years.

The material can even have enough conductivity to be used as an antistatic coating

Unique electrical properties of Teflon spraying. In a fairly wide frequency range, Teflon coatings have high insulation strength, low dielectric constant, and extremely high surface resistance. Teflon spraying heat resistance Teflon? Industrial coatings can work continuously under temperature conditions up to 260°C/500°F; under the condition of sufficient ventilation, the short-term use temperature can reach 315°C/600°F . 


 Industrial coatings can be used at low temperatures as low as -270°C/-454°F.html Teflon spray, Teflon spray,.kytfl.Teflon spray non-wetting property Since the surface coated with Teflon® is both oleophobic and hydrophobic, it will not be easily wetted. The only two chemicals known to affect Teflon, industrial coatings are molten alkali metals and highly reactive fluorinating agents. Cleaning is easier and more thorough—in many cases, these surfaces can be self-cleaning.

Coating type.20, depending on the load, sliding speed and the specific Teflon used. Teflon spray chemical resistance PTFE Coated Fabric Generally speaking, Teflon is not affected by the chemical environment. Low temperature stability of Teflon spraying Many industrial Teflon coatings can withstand harsh extreme temperature conditions without compromising their physical properties.

Low friction coefficient Teflon? The friction coefficient of the coating is generally in the range of 0. Through special technology, the material can even have enough conductivity to be used as an antistatic coating

A large number of technical personnel retired

In the middle and late 1990s, due to economic benefits, a large number of technical personnel retired, which affected the in-depth research and development of fluoroplastics processing. After 40 years of development, the fluoroplastics processing industry is gradually transitioning from the production of semi-finished products to the production of auxiliary products in the automotive, electronics, chemical, machinery, building materials, environmental protection, textile, and food industries. 


Development of fluoroplastics 2. It has been widely used in aerospace, atomic energy, electronics, electrical, chemical, machinery, construction, textile, pharmaceutical and other industries. 

The products that have been industrialized and sold on the market include polytetrafluoroethylene (PTFE), Polyvinylidene fluoride (PVDF), ethylene-tetrafluoroethylene copolymer (ETFE), ethylene-chlorotrifluoroethylene copolymer (ECTFE), polyvinyl fluoride (PVF), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer There are about 100 brands of more than ten varieties, including PFA, tetrafluoroethylene-hexafluoropropylene copolymer (also known as polyperfluoroethylene propylene FEP), and polychlorotrifluoroethylene (PCTFE). 

 In the 1980s, on this basis, my country's fluoroplastic processing enterprises (mainly township enterprises) were established, especially in Jiangsu and Zhejiang provinces, which greatly promoted the growth of my country's fluoroplastics processing industry. Sector, and increasingly penetrate into people’s daily lives. In recent years, China's sustained and rapid economic growth has provided a broad market space for fluoroplastic products.1 Historical review of fluoroplastic molding process research and product processing in China The history of the development of the fluoroplastics processing industry in China is a typical epitome of the Shanghai Plastics Research Institute. S.. 

It was the earliest established research institute mainly engaged in the research of fluoroplastics molding process in China. Some products have replaced imports, and some A large number of products go to the international market. In the late decade, a series of process technologies such as compression molding, push molding, blow molding, injection molding, (spiral) extrusion molding, dipping, coating, and surface treatment of fluoroplastics have been researched, and corresponding technologies have been established. 

It is difficult to replace other conventional plastics, so its economic benefits are much higher than conventional plastics. Although processing is relatively difficult, they have high thermal stability, low dielectric constant, low moisture absorption, low flammability, low surface energy, excellent weather resistance and excellent chemical resistance. 

Since Plunkett synthesized polytetrafluoroethylene, the development, production, processing and application of fluoroplastics have been greatly developed, so there are many varieties. Since 1938, American scientist R. Test, test methods, and theoretical basis BBQ grill mat Manufacturers for the design of molds and non-standard molding equipment. Fluoroplastics are polymer materials with excellent performance.1 Introduction Fluoroplastics are an important type of plastics with excellent performance. It was established in 1958 and was formally established in 1963
