Abstract
The environmental test cabin method was used to simulate the actual use environment of car mats to collect test gas, The formaldehyde content in the collected gas was measured by ultraviolet spectrophotometer, and the formaldehyde release rate was calculated. The results indicated that formaldehyde was released in all 30 batches of samples at a rate ranging from 0.02 to 0.13mg/ m2 (m2•h).
Highlights
As people's living standards are getting higher and higher, the number of cars in China is increasing year by year, and cars have gradually become the means of transportation for people's daily travel[1]
The problems of product quality and safety are reflected in the use safety and air pollution in the car
Determine the formaldehyde content according to the standard curve
Summary
As people's living standards are getting higher and higher, the number of cars in China is increasing year by year, and cars have gradually become the means of transportation for people's daily travel[1]. As an important automotive interior product, the quality of the automotive floor mat directly affects the automotive interior environment. Inferior floor mats emit toxic and harmful gases, which is one of the main causes of air pollution in the vehicle. GB/T 27630-2011 guidelines for air quality evaluation in passenger cars set corresponding requirements for the limits of eight volatile organic compounds such as benzene in the air in the vehicle, but for the car floor mats, There is no corresponding national standard. Formaldehyde can enter the human body through the respiratory tract It has the characteristics of long-term, latent and hidden. The production is mainly concentrated in Xinle City of Shijiazhuang and Nangong city of Xingtai. The problems of product quality and safety are reflected in the use safety and air pollution in the car. The environmental test chamber is used to simulate the actual use environment of automobile foot pad products, collect the test gas, test the formaldehyde content in the collected gas by UV-Vis spectrophotometer, calculate the formaldehyde release rate, and discuss the use risk of automobile foot pad products
