Instrumentation industry will see an inflection point in the industrial structure
Asbestos was added as an common ingredient to Brake Pads post-WWI, as car speeds began to increase, because research showed that its properties allowed it to absorb the heat (which can reach 500 °F) while still providing the friction necessary to stop a vehicle. However, as the serious health-related hazards of asbestos eventually started to become apparent, other materials had to be found. Asbestos brake pads have largely been replaced by non-asbestos organic (NAO) materials in first world countries. Today, brake pad materials are classified into one of four principal categories, as follows:
Non-metallic materials - these are made from a combination of various synthetic substances bonded into a composite, principally in the form of cellulose, aramid, PAN, and sintered glass. They are gentle on rotors, but produce a fair amount of dust, thus having a short service life.
Semi-metallic materials - synthetics mixed with varying proportions of flaked metals. These are harder than non-metallic pads, more fade-resistant and longer lasting, but at the cost of increased wear to the rotor/drum which then must be replaced sooner. They also require more actuating force than non-metallic pads in order to generate braking torque.
Fully metallic materials - these pads are used only in racing vehicles, and are composed of sintered steel without any synthetic additives. They are very long-lasting, but require more force to slow a vehicle while wearing off the rotors faster. They also tend to be very loud.
Ceramic materials - Composed of clay and porcelain bonded to copper flakes and filaments, these are a good compromise between the durability of the metal pads, grip and fade resistance of the synthetic variety. Their principal drawback, however, is that unlike the previous three types, despite the presence of the copper (which has a high thermal conductivity), ceramic pads generally do not dissipate heat well, which can eventually cause the pads or other components of the braking system to warp.However, because the ceramic materials causes the braking sound to be elevated beyond that of human hearing, they are exceptionally quiet.

The instrumentation industry mainly serves the petrochemical, thermal power, nuclear power, wind power, rail transportation and other fields. The prospects for the development of these industries are closely related to the development prospects of the instrumentation industry. In the National Twelfth Five-Year Plan, many industries have pointed out that the changes in market demand are relatively rapid, the adjustment of product structure is urgent, and the economic development rate is slowing down. However, whether other industries slow down the pace of development will affect the market demand for instrumentation and whether there will be a new turning point in the instrumentation industry. The answer is in fact affirmative. However, this inflection point does not mean that the instrumentation will be declining. On the contrary, the industry will make major adjustments to the industrial structure along with other industrial industries.
With rapid economic and fierce competition, the instrumentation industry has also exposed some of the current problems. We still face the lack of scientific and technological content, poor innovation capabilities, the market is more chaotic, not enough concentration, and lack of strong national major projects. Support.
At present, China is moving toward the ranks of industrialized countries. One of the issues is how to develop the instrumentation industry. China Instrument and Instrument Network pointed out that China's instrumentation industry can follow the requirements of the country's macroeconomic policies and "strengthen innovation, pay close attention to the basics, market orientation, broaden the scope, institutional innovation, optimize the structure, and continue to promote and revitalize the industry." For strategy. The instrumentation industry will target the high-end product market to improve the stability and reliability of products; aim at the country's strategic emerging industries, expand the traditional areas of service into emerging areas; and vigorously strengthen the adjustment of enterprise structure through certain joint In the form of mergers and other forms, we will strive to build a number of leading enterprises; strengthen the continuous advancement and long-term investment in the achieved results, maintain the continuous accumulation of core technologies, and form a mechanism for the sustainable development of the industry.
In this inflection point, the industry will enter into a new phase through adjustment and adjustment. It basically completes the autonomy of typical equipment control systems in petrochemical, thermal power, nuclear power, wind power, rail transit, etc., and basically meets the needs of key areas represented by environmental protection, food and drug safety, and emergency public safety handling.
