Embodiment 1
[0082] 1. Cleaning and equipment confirmation before the test
[0083] (1) Check the tightness and other functions of the airtight chamber; use tire 1.
[0084] (2) Clean all surfaces in the airtight chamber that are in contact with volatile organic components. The specific cleaning method is as follows: Use mechanical cleaning methods (such as industrial vacuum cleaners) to remove residual particles and impurities from the previous test, then use high-temperature baking to age the cabinet, turn on the mixing fan in the closed room, and clean the closed room for several minutes. Until the background total hydrocarbon concentration drops below 1ppm at the hot soak temperature and remains stable (at least 30min), bake and clean related accessories such as sealing rings.
[0085] (3) Monitor and record the background concentration in the airtight chamber before the test starts after cleaning.
[0086] (4) Before the test starts, remove the tire from the package, and place it in...
Embodiment 2
[0105] The test method is the same as in Example 1, except that tire 2 is used.
Embodiment 3
[0109] The test method is the same as in Example 1, except that tire 3 is used.

The invention provides a test and traceability rectification method for hydrocarbon pollutants of an automobile tire. The method comprises the following steps of: S1, carrying out cleaning and equipment confirmation before a test; S2, carrying out a hot dipping test; S3, performing normal-temperature sample soaking in a closed chamber, and setting the closed chamber to be in a maximum ventilation state; S4, performing a day and night ventilation test; and S5, calculating the results of day and night ventilation and hot dipping stages in various evaporative pollutant discharge tests described according to a test program, and analyzing carbide to determine the substance information of hydrocarbon. According to the test and traceability rectification method for hydrocarbon pollutants of an automobile tire, an efficient tire hydrocarbon pollutant test method based on the national VI emission standard is formed, the test efficiency of the test method is improved by nearly 50%, the main hydrocarbon pollutants are analyzed and traced through sampling, the types of the main hydrocarbon pollutants are determined, accurate directional data are provided for adjustment of a tire formula, and the problem on reduction of hydrocarbon pollutants of a tire is essentially solved.
Description
technical field [0001] The invention belongs to the field of inspection and chemical analysis of automobile tires, and in particular relates to a method for testing and rectifying hydrocarbon pollutants of automobile tires. Background technique [0002] At present, the impact of pollutants produced by automobiles on the atmospheric environment is becoming more and more prominent and serious. According to research, volatile organic compound (Volatile organic compound, referred to as VOC) emissions in my country cause 20% to 30% of PM2.5 and 47% One of the main sources of VOC emissions is the carbon and hydrogen emissions of vehicles. my country has a large number of cars, which can produce about 1.1 million tons of carbon and hydrogen emissions every year, and they are concentrated in urban areas, directly causing 7% to 12% of PM2.5 and 15% to 20% of smog, which has a significant impact on the environment . [0003] The carbon and hydrogen emissions of automobiles have attrac...
