| With the development of economy and society,the number of cars keeps increasing,and the Automobile Exhaust of a large number of vehicles causes the deterioration of atmospheric environment.Nano-Ti O2 material has the characteristics of high efficiency,safety,and can be recycled,and used in the oxidation of pollutants in the exhaust gas of the automobile under the action of the sunlight purple light line,so as to play the role of air purification.Because the road surface is the first contact of the automobile exhaust,it is important to study the application of nano-Ti O2 material on the road surface for automobile exhaust degradation.This paper summarized the domestic and foreign research data,firstly summarizes the nano-Ti O2 automobile exhaust degradation mechanism and the method of modification to improve the degradation efficiency,and considering the deficiencies of the existing automobile degradation test equipment,developed new equipment can provide uniform illumination conditions and stable temperature conditions,determine its components,steps,test the condition and effect of degradation evaluation index;and then to car exhaust NO as an example,the influence of spreading amount on NO degradation effect of nano-Ti O2 particles using direct spreading,analysis and preparation of nano Ti O2 coating when shear rate,nano-Ti O2 dosage and dispersing agent on the removal effect of law;in addition,study nano-Ti O2 coating dosage of anti sliding properties of asphalt mixture,and analyzed by emery to improve its content to improve effect;finally,based on the The skid resistance,NO degradation effect and durability of nano-Ti O2 coating were studied by accelerated wear test. |
