Environmental protection instrumentation market has great potential
Environmental protection has increasingly been taken seriously by people of all countries. While concentrating on developing the economy, China has also made environmental protection a basic national policy. As a result, the development and use of environmental protection instruments are increasingly being taken seriously. Experts in the industry believe that in the future, the environmental protection instrumentation industry product market will have a substantial increase with the focus on strengthening environmental protection law enforcement, accelerating the pace of environmental protection construction, increasing investment in environmental protection construction, and fostering the need for a new growth point in the national economy. Especially in environmental protection instrumentation, the demand for environmental monitoring automation control system products for atmospheric environment and water environment will be very strong.
The main market demand for environmental protection instrumentation
Environmental protection instruments are mainly used in environmental quality monitoring and pollution source monitoring. For our country's detailed national conditions, environmental protection is mainly to solve China's water environment, atmospheric environment, two strategic and overall environmental pollution problems. In detail, the main requirements for environmental protection instrumentation are as follows:
(I) Environmental Quality Monitoring. At present, the national environmental protection system and various parts, industries, and enterprises have built more than 4,000 monitoring stations, employ more than 60,000 employees, and many environmental research institutes. In recent years, it has been the period of environmental science and monitoring and analysis instruments, equipment replacement and progress. The National Environmental Protection Agency plans to equip the country with more than 400 national network monitoring stations; more than 350 environmental information centers: one hundred urban air ground automatic monitoring systems. Initial plans to invest 1.5 billion yuan, of which two-thirds of state investment, one-third of local investment. This does not include the investment in the capacity building of monitoring stations for industries, localities and enterprises. Each part and each locality has its own investment plan according to the needs of environmental protection tasks.
(II) Monitoring of pollution sources: The state must control and reduce the total amount of pollutants discharged from the sands of Vietnam's 180,000 key polluting enterprises in order to improve the quality of the environment. Therefore, 18,000 large-scale polluters are required to gradually install online continuous automation. Monitoring System. There are few mature domestic instrument systems, and the demand is much greater than the environmental quality monitoring, which is mainly purchased by polluting companies. The industries are mainly electric power, petrochemicals, building materials, metallurgy, paper making, food and urban sewage treatment plants, etc. The latent market has billions to tens of billions of yuan.
(III) Remote Sensing Telemetering Instrumentation: The state puts forward the principle of putting equal emphasis on environmental pollution prevention and ecological environmental protection. To strengthen ecological environmental protection, it is necessary to monitor the ecological environment in China. Including monitoring of deserts, grasslands, forests, oceans, and agro-ecological environments, it is also necessary to carry out remote sensing telemetry of air pollution, water pollution (such as ocean red tide, oil spill pollution) and pollution sources, and to establish satellite ground receiving systems and satellite image analysis. The system analyzes the current status and trend of environmental ecological quality and provides the scientific basis for the national environmental protection and construction plan.
At present, the urgent need of domestic environmental protection instruments and meters include: atmospheric environmental quality monitoring equipment and automatic monitoring systems; coal-fired power stations or boilers represented by the flue gas analysis instrumentation monitoring system; surface water environmental quality testing instruments and monitoring systems; to urban sewage treatment Plants and high-concentration organic wastewater represented by pollution source monitoring instruments and automatic control systems.
Composite Nylon Plastics Material PA66
Main Properties of PA6 and PA 66
PA6 & PA66 are by far the most used polyamides globally. Both Polyamide 6 (PA6) and Polyamide 66 (PA66) are widely used in many different markets and applications due to their excellent performance/ cost ratios. Their key properties are listed below.
High strength and stiffness at high temperature
Good impact strength, even at low temperature
Very good flow for easy processing
Good abrasion and wear resistance
Excellent fuel and oil resistance
Good fatigue resistance
PA 6 has excellent surface appearance and better processability than PA66 (due to its very low viscosity)
Good electrical insulating properties
High water absorption and water equilibrium content limits the usage
Low dimensional stability
Attacked by strong mineral acids and absorbs polar solvents
Proper drying before processing is needed
Although, they exhibit similar properties, slight differences do remain. PA6 has a slightly lower temperature resistance versus PA66 and is also slightly less expansive.
