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
