Recently, the General Office of the Gansu Provincial Government issued the “Implementation Measures for the Elimination of Exhaust Emissions from Yellow Gas Vehicles and Old and Endangered Motor Vehicles in Gansu Province†(hereinafter referred to as the “Measuresâ€), and clearly stated that by the end of 2015, the basic phase-out before the end of 2005 Registered to operate the "Yellow Label Vehicle"; by the end of 2017, the "Yellow Label Vehicle" within the province of Gansu will be basically eliminated.
Acrylonitrile butadiene styrene AKA Abs Resin (chemical formula (C8H8)x·(C4H6)y·(C3H3N)z) is a common thermoplastic polymer. Its glass transition temperature is approximately 220 °F (104 °C). ABS is amorphous and therefore has no true melting point.
Abs Repair Resin is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene Rubber And Plastic. The proportions can vary from 15% to 35% acrylonitrile, 5% to 30% butadiene and 40% to 60% styrene. The result is a long chain of polybutadiene crisscrossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The acrylonitrile also contributes chemical resistance, fatigue resistance, hardness, and rigidity, while increasing the heat deflection temperature. Abs Plastic Resin gives the plastic a shiny, impervious surface Ethylene-Vinyl Acetate, as well as hardness, rigidity, and improved processing ease. The polybutadiene, a rubbery substance, provides toughness and ductility at low temperatures Pvc Resin, at the cost of heat resistance and rigidity. For the majority of applications, ABS can be used between −20 and 80 °C (−4 and 176 °F), as its mechanical properties vary with temperature. Abs Casting Resin properties are created by rubber toughening, where fine particles of elastomer are distributed throughout the rigid matrix.

The "Measures" clearly stated that Gansu Province will speed up the elimination of "yellow standard vehicles" and scrapped old vehicles. By the end of 2015, the “Yellow Label Vehicle†registered before the end of 2005 will be basically phased out; by the end of 2017, the “Yellow Label Vehicle†within the province will be basically eliminated; the old vehicles will be scrapped in advance; new production will be started from 2015. Low-speed trucks perform the same emission standards as light-duty trucks.
The "Procedure" proposes that motor vehicles that have passed the environmental protection inspections meet the national emission standards and are exempt from inspections, and the environmental protection departments issue green environmental protection inspection marks; for vehicles that fail to meet the national emission standards, they issue yellow environmental protection. Inspection mark. The environmental protection department can supervise and test the pollutant discharge status of the motor vehicles in use at the parking place of the motor vehicle. There is no charge for sampling of motor vehicles. At the same time, in accordance with the Ministry of Finance and the Ministry of Commerce, "Administrative Measures for Retirement and Subsidy Funds for Old Cars," appropriate subsidies will be given to car owners who meet the subsidy conditions determined by the Ministry of Finance and the Ministry of Commerce, handle old car scrapping procedures, and purchase new cars.
Governments at all levels should encourage the production of motor vehicles that use clean fuels such as compressed natural gas and liquefied petroleum gas, and promote the use of state-recognized vehicle exhaust pollution control technologies, devices, and automotive fuel additives. The municipal (state) and county (city, district) governments should actively coordinate and reduce the emission of nitrogen oxides from motor vehicles by improving fuel quality. Before the end of 2014, the province fully implemented the four national emission standards for motor vehicles, and fully supplied the national four-vehicle gasoline and diesel. By the end of 2017, it will fully supply the country's five-vehicle gasoline and diesel.
