The Five Sticking Point Restricts The Development Of Filter Materials

With the rapid development of the global economy and the increasing consumption of energy, serious environmental pollution is followed. The high temperature flue gas and dust in the power, steel, metallurgy, building materials, chemical industry, waste incineration and other industries are particularly polluting the atmosphere.

Therefore, the development and utilization of filter materials for environmental protection is extremely important. The market prospect of filtration materials is considerable.

Especially in recent years, in order to meet the requirements of various high temperature flue gas conditions, developed countries are actively developing various kinds of flue gas.

New filtering materials develop vigorously

In the field of flue gas filtration, China developed in the 70s of last century.

The development trend of high performance filter materials is to meet the requirements of high temperature resistance, oxidation resistance, acid and alkaline resistance, and antistatic. In some working conditions, functional requirements such as decomposition and removal of harmful gases such as dioxins must be satisfied. At the same time, it will also promote the development of new high-performance fibrous materials and upgrading of filter processing technology.

For the different environmental conditions of filter media and filtration conditions, the application market of high performance filter materials will be further subdivided, more optimized, targeted to adapt to and meet different filter environment conditions, thus further promoting the development of filter materials and improving the technology level of filter process.

At present, China has a certain foundation for the pformation of textile power, especially in the field of new filter materials for industry. In the past, China has been heavily dependent on imports in the field of high temperature and high performance filtration materials. Now China has basically the ability to produce high temperature resistant and high-performance filtration materials, and some of its high-performance fibers have also been industrialized in China.

The production technology of high performance filter materials in China has been developed from traditional two-dimensional woven fabric to three-dimensional non-woven filter cloth, from conventional products to high temperature resistant, corrosion resistant, multi-functional, high-quality filter materials.

The processing techniques and methods include needling, spunlacing, spunbonded + needle punched, spunbonded + Spunlaced, woven,

Five aspects need improvement

After entering the twenty-first Century, China has made remarkable progress in the development of high-performance filtration materials. It has been widely applied in various fields such as metallurgy, iron and steel, cement, coal-fired power plants, and so on. It improves the filtration efficiency and filtering accuracy of high temperature dust, reduces the emission of flue gas and dust, improves the atmospheric environment quality and improves the air quality in China.

However, due to the large number of enterprises, industries and fields involved in the control of flue gas and dust reduction in our country, the total amount of dust emission reduction in the air is still only the tip of the iceberg. The heavy and heavy work needs to be further expanded to expand the scope of application and Application of high performance filter materials.

The development and popularization of high performance filter materials in our country are imperfect, mainly due to several reasons:

First, the research and development of filtration materials and developers do not fully understand the requirements of the application industry and the working conditions of the field, and can not develop timely matching materials for production, resulting in poor results.

At the same time, there is also a lack of publicity in the application field, which makes the application area unclear and unclear, leading to no use.

Two, there is a lack of comprehensive understanding of the material properties of high performance filter materials in the application industry and field.

At the same time, there are some internal interest groups in the application industry driven by the interests of exclusion and hinder the application of high-performance filter materials.

The three is the shortage of research funds and the absence of organization and coordination.

Although the state has invested a lot of money in improving atmospheric quality in China, the development, development, popularization and application of new high performance filter materials will have considerable workload and technical difficulties. A large amount of research funds will be needed for research and development. At the same time, there will be more active coordination and coordination involving multi fields, multi disciplines and multi departments, so that the units and departments that can lead the organization and coordinated development of such a cross disciplinary and interdisciplinary research and development need to be absent.

This has resulted in a situation of self governance, mutual communication, and even some mutual impediment, resulting in the rapid development of high-performance filtration materials in some application fields.

Four, the high-performance fiber materials used for high-performance filter materials in China are still not perfect. The existing industrial products have defects in performance and defects in performance. The defects of materials usually determine the value of their use. For example, the poor acid resistance of aramid fiber can not be used in the bag dust collecting environment of coal-fired power plants. Polyphenylene sulfide fibers can not be used in the bag and dust collecting environment of iron and steel and metallurgy because of the poor heat resistance. Some high performance materials are expensive, resulting in high cost in the application field and not being used. Therefore, the high-performance fiber materials in China can not fully meet the application needs and market segmentation requirements in the field of.

Five, the evaluation system of filtration materials needs further establishment and improvement.

The evaluation of high performance filter materials in China is still needed to be established, perfected and perfected on the basis of comprehensive, authoritative and impartial.
