Beijing Tongzhou builds air pollution online source analysis super station
In recent years, with the continuous strengthening of air pollution control in my country, my country's atmospheric environment monitoring network with urban ambient air quality monitoring stations, regional air quality monitoring stations and background value monitoring stations as the main body has been continuously improved, and many places have begun to build Atmospheric monitoring super station. since“Blue Sky Defense”Since its inception, Tongzhou District has increased investment in environmental detection technology, and has established monitoring networks such as automatic monitoring of atmospheric particulate matter, online monitoring of oil fume in the catering industry, online monitoring and supervision of dust on construction sites, and vehicle navigation monitoring. The above monitoring systems are targeted, but there are still some pollution sources that cannot be monitored in real time, and some pollution components are not yet grasped, such as vehicle exhaust emissions and residential pollution. in order to implement“fourteen five”The green development goal in the plan is to comprehensively evaluate the current situation of ambient air quality, and grasp the composition and changing trend of pollution. Tongzhou District Ecological Environment Bureau has specially built a super station for online source analysis of air pollution, which can quantitatively analyze the pollution composition and air pollution in Tongzhou District through component monitoring. Its contribution rate guides the government to implement precise policies. Compared with the existing air quality assessment stations, the super station has added monitoring capabilities such as source analysis, VOCs, and OCEC. The source component spectrum can quantify the source of pollution, accurately analyze the proportion of pollution in various industries, the impact of meteorological factors, and the impact of regional transmission, and accurately grasp the source, composition, and classification of particulate matter in key areas.“speak clearly”,“see clearly”. Strengthen the management of controllable pollution sources, and grasp the pollution proportion of uncontrollable pollution sources in real time. Provide data support for regional and structural research on prevention and control measures. The atmospheric environment monitoring super station is equivalent to the super station in the monitoring station.“special forces”, ordinary monitoring stations can“caught”common air pollutants, for elusive“stubborn enemy”just need these“special forces”out. The establishment of the super station in Tongzhou District further meets the needs of atmospheric environmental pollution control, conducts in-depth observation of atmospheric environmental quality, and provides basic scientific data for the prevention and control of atmospheric pollution in Tongzhou District.
Ball Burst Method (ASTM D3787): Steel ball penetration for textiles/films using testers like GT-C02-2.
Hydraulic Method (ISO 13938.1): Fluid pressure on rubber diaphragm for industrial fabrics via GT-C12A.
Pneumatic Method (ISO 13938.2): Compressed air for breathable materials tested with GT-C12B.
Results are influenced by raw materials, yarn properties,
1. ISO 5402-1: Specifies the flexometer method for testing leather flex resistance under repeated bending.
2. ISO 17694: Defines test methods for footwear upper and lining flex resistance, simulating real-world bending stress to assess long-term durability.
