Recently, such a news spreads on the Internet, the standard of automobile brake pads has for the first time added environmental protection indicators, and the country’s first environmental protection brake pad standard will be introduced soon. However, the industry's focal point, the China Friction Materials Association, has not received any relevant application. In response, the reporter dialed the telephone of the Xiapu County Quality Inspection Bureau mentioned in the news and made repeated efforts to finally find the relevant person in charge. According to him, the standard is jointly formulated by the alliance of several local automobile friction fittings manufacturers and belongs to corporate standards. The person in charge said: "The introduction of new technical indicators, indirectly encourage manufacturers to reduce the use of asbestos raw materials, intended to reduce pollution while achieving the purpose of improving product performance."
As for asbestos brake pads should continue to use, has been debated in the industry for a long time. The reporter found that this controversy is still continuing. It is understood that in the field of passenger vehicles, the shadow of asbestos brake pads has basically not been seen. Asbestos brake pads are still widely used in commercial vehicles, especially heavy commercial vehicles. "Asbestos brake pads are low in cost and light in weight. This is why many commercial vehicle companies still use asbestos brake pads." Wang Yao, chairman of the China Friction Materials Association, told reporters.
Chrysotile has a comparative advantage
Asbestos is a collection of natural fibrous substances and is used in more than 20 industrial sectors such as automobiles, chemical industry, and electrical equipment. Asbestos is generally divided into three categories according to composition and structure differences: amphibole asbestos (blue asbestos), chrysotile and brucite asbestos. It is understood that the United States, European Union countries, etc. issue a ban and prohibit asbestos consumption. The reason is that if asbestos fiber is inhaled, it can cause asbestos lung, pleural mesothelioma and other diseases.
This is where the debate begins. Some experts pointed out that asbestos in asbestos is different from the other two kinds of asbestos, and the inhalable matter it produces is inhaled by the human body and can be automatically removed without damaging the human body. Some experts believe that as long as the dust density of chrysotile asbestos and the inhalation of personnel are controlled, chrysotile asbestos can be safely used. An industry source told reporters that chrysotile is resistant to high temperatures and high strength. It is a natural material for producing brake pads. Considering comprehensive cost performance, asbestos brake pads have a comparative advantage. Therefore, in the field of some low-priced cars and heavy-duty vehicles in China, chrysotile cotton brake pads also have a certain market. At present, China's asbestos brake pads are mainly made of asbestos as a reinforcing material, and phenolic resin is used as a friction modifier. It is made of film and plastic and is used in brake systems of trucks.
As many countries in the world have banned the use of asbestos products, the export of brake pads in China has been severely hindered. More and more companies are beginning to develop non-asbestos brake pads in order to adapt to the international market.
Asbestos brake pads encounter market bottlenecks
As a major exporter in the domestic brake pad industry, Shandong Jin Qilin Group has developed a third generation of improved low metal brake pads, NAO (non-asbestos organics) brake pads and high-end ceramic brake pads. Hu Qiang, deputy general manager of the group, told reporters: “Gold Kirin introduced North American technology from the very beginning of its construction and started to develop semi-metal brake pads, so it has not encountered the difficulties encountered by manufacturers of asbestos brake pads.†According to him, Jin Qilin Group can produce more than 2000 varieties of non-asbestos brake pads for passenger cars, light vehicles and trucks. The products are exported to North America, South America, Europe, Australia and other countries and regions, and the export volume accounts for more than 85% of the total output.
In contrast, Xiapu County, Fujian Province, automobile friction parts industry is due to the company more production of asbestos brake material in the market gradually in a weak competition, market share has been squeezed. In order to help local companies break through the development bottleneck, the Xiapu County Quality Inspection Bureau took the lead in carrying out visits and investigations to guide local companies to establish the Fujian Sansha Automobile and Motorcycle Fittings Alliance and organized a conference on alliance standards. The person in charge of Fujian Xiapu Zhengyang Friction Industry Co., Ltd. told reporters that because of their achievements in the development of non-asbestos brake pads, they led the drawing up of relevant corporate standards, prompting local companies to shift from asbestos brake pads to research and development of semi-metallic brakes. Tablets and non-asbestos brake pads.
Non-asbestos brake pads adapt to international market environment
“The cost of non-asbestos brake pads is actually 20%~30% higher than asbestos brake pads. Although the cost of asbestos brake pads is low, it has no international market. Once a company exported a batch of semi-metal brake pads to the United States. Due to the asbestos content of their products, they were all returned," Hu Qiang told reporters.
Asbestos brake pads are difficult in the international market. Therefore, in order to meet the needs of the international market, the development of non-asbestos brake pads is in line with the laws of the market. "Wang Yao said," What kind of products the market needs, what kind of products the company will produce, this is the market economy. â€
It is understood that there are several different brake pad technology technologies in the world. North America has the most successful research and application of semi-metal brake pads. Europe focuses on the study of less metal formulations, while Japan studies NAO (non-asbestos organics) formulations. Industry insiders told reporters that the formula of small metal and NAO formula have become the trend to guide the development of friction materials.
At present, the research efforts of non-asbestos brake pads by Chinese companies are increasing, and products have entered the international market one after another. Insiders pointed out that at present, China's asbestos brake pads still occupy a considerable proportion in the heavy-duty brake pad market, but with the semi-metal formula, the development of less metal formulas and the continuous advancement of NAO formula technology, heavy-duty brake pads The market is also constantly occupied by non-asbestos brake pads.
An air cooler turbine is a device used in an air cooler that increases air flow and improves air cooling efficiency. A turbine is a rotating piece made up of a series of blades that turn as air passes through the turbine, creating a powerful flow of air. This airflow takes heat out of the air, making it cooler. The air cooler turbine is usually driven by a motor and can be adjusted as needed for speed and air volume. It is widely used in automobile, robot, electronic equipment and other fields.
Air cooler, referred to as "air cooler", also called fin fan, commonly used to replace the water cooled shell - tube Heat Exchanger cooling medium. It is a device for cooling or condensing the high temperature process fluid inside the tube by sweeping the finned tube with ambient air as the cooling medium. Air cooler is mainly used in petroleum, chemical, metallurgy and other air cooler supporting use, with large air volume, high efficiency, low vibration, low noise, easy maintenance and other advantages.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.
