The reporter learned from the Provincial Environmental Protection Department yesterday that Guangdong has implemented the national standard for motor vehicles in advance: since March 1, 2015, the implementation of the national standard for light gasoline vehicles in the Pearl River Delta region; since July 1, 2015, in eastern Guangdong In the northwest region, the national standard for light gasoline vehicles will be implemented; since July 1, 2015, the national standard for heavy-duty diesel vehicles will be implemented in the public transportation, sanitation and postal industries in the Pearl River Delta region. Since July 1 last year, 14 cities in Guangdong including Guangzhou have begun to supply “National Five Oilsâ€. Half-month transition period It is reported that the State Council has agreed to implement the fifth phase of national motor vehicle air pollutant emission standards in advance . According to the relevant requirements of the Regulations on the Prevention and Control of Motor Vehicle Exhaust Pollution in Guangdong Province (revised in 2010), the fifth phase of national motor vehicle air pollutant emission standards will be implemented in advance with the consent of the provincial people's government. From March 1st, light-ignited engine vehicles sold, registered and transferred in the Pearl River Delta region shall comply with the national emission standard “Light Vehicle Pollutant Emission Limits and Measurement Methods (China Stage 5)†(GB 18352.5) -2013) Emission control requirements, implementation of OBD system NOx monitoring and OBD actual monitoring frequency (IUPR) related requirements; at the same time, stop sales, registration and transfer to vehicles that do not meet the above requirements. The Guangdong-East-North region was postponed until July 1st to implement the above requirements. For the heavy-duty compression-ignition engine vehicles of the bus, sanitation and postal industries that are sold, registered and transferred in the Pearl River Delta region, the circular requires the implementation of the fifth phase of national motor vehicle air pollutant discharge standards from July 1. The notice also stipulates that from now until February 28, 2015, the transition period, vehicle sales during the transition period, registration of new vehicles, change registration of foreign transfer and transfer registration can still be implemented according to the original standards. More strict emissions standards Motor vehicle pollutant emissions are an important source of air pollutant emissions. In order to control motor vehicle pollution, Beijing and Shanghai have already implemented the fifth phase of national motor vehicle air pollutant emission standards. In February of this year, the Guangzhou Municipal Environmental Protection Bureau released the analysis of the source of PM2.5 in Guangzhou. In 2014, motor vehicle exhaust gas accounted for 21.7% of Guangzhou PM2.5 emissions, second only to industrial sources. Environmental experts said that the implementation of the fifth phase of national motor vehicle air pollutant emission standards in advance is very necessary for Guangdong and has been fully demonstrated. The national five emission standards have further improved the emission control requirements, in which the nitrogen oxide emission limit is strictly 25% to 28%, the particulate matter emission limit is 82% strict, and the number of particulate matter particles in the new pollution control index is increased, and the control level is equivalent. The fifth phase of light vehicle emissions regulations being implemented in Europe. According to the person in charge of the Provincial Environmental Protection Department, the public can log in to the Guangdong Environmental Protection Public Network to inquire about the model list of the fifth-stage national motor vehicle air pollutant emission standards. An insider of a domestic automobile manufacturer said that if a car manufacturer wants to produce a car that meets the national five standard, it must carry out a lot of technical improvements and install many cleaning equipment. Adding these equipment will inevitably increase the manufacturing cost of the car. As a result, the price of the car has risen, which may increase the cost of car purchase for consumers who are about to purchase a new car.
China 42Mm Friction Bolt,Split Set Bolt supplier & manufacturer, offer low price, high quality Mining Bolt,Split Set Rock Bolts, etc.
Split set bolt is also called "Split Set Stabilizer". It was successfully developed by American Professor Scott in the early 1970s. It was used as a patented product by Ingersoll Rand for mining support. In the early 1980s, the Beijing Institute of Well Construction conducted exploratory tests on slotted pipe anchors in the laboratory and achieved good results. Later, it was gradually promoted and applied in the coal system.
Split set bolt is a underground mining support product. It has simple installation process and convenient use. It has strong anchoring force and tensile strength in underground mining and shotcrete support. It has Large force, strong expansion force.
Split set bolt has good supporting effect. Bolt support conforms to modern rock mechanics and surrounding rock control theory in terms of support principles, and belongs to active support. After the bolt is installed, the stability of the surrounding rock can be mobilized and utilized, and the bearing capacity of the surrounding rock can be fully utilized, and controls the deformation of the surrounding rock of the roadway effectively.so split set bolt can protect the stability of the surrounding rock of the roadway and improve the maintenance of the roadway.
Split set bolt has simple installation and labor saving. It uses fewer supporting materials and lighter weight than other bolts. When tunneling, the transportation volume of supporting materials is reduced, and the labor intensity is greatly reduced, which is conducive to improving the efficiency of tunneling.
