Device for displaying volatilization rate and volatilization level of harmful substances of decorative materials

Abstract

The invention relates to a device for displaying the volatilization rate and the volatilization level of harmful substances of decorative materials, and belongs to the field of indoor environment treatment. The device comprises a test chamber, a heating plate, an indoor air pollutant treatment system, a temperature display and control device and a temperature sensor, a plurality of sampling openings are machined in the side wall of the test chamber, a heating plate and an indoor air pollutant treatment system are installed in the test chamber, the heating plate and the temperature sensor are electrically connected with a temperature display and control device, and the temperature sensor is installed in the test chamber. According to the device, the pollution emission condition of decoration building materials in a cold region indoor environment is simulated and detected; the pollutant emission levels of the building materials under different heating conditions are mastered, a corresponding pollutant treatment method is formulated according to specific environmental conditions and pollutant distribution conditions, and the device for displaying the volatilization rate and volatilization level of the harmful substances of the decoration materials is simple in structure, ingenious in design, convenient to disassemble and assemble and suitable for application and popularization.

Description

technical field [0001] The invention relates to a display device for volatilization rate and volatilization level of harmful substances in decoration materials, which belongs to the field of indoor pollution detection and air treatment. Background technique [0002] With the continuous progress of society and the continuous improvement of living standards, there are more and more new buildings in our country, and interior decoration has become a practical problem that every household must face. In the process of market research, we found that the environmental protection effect of decoration materials promotion is relatively ideal. However, in fact, the problem of IAQ decline in indoor air quality after renovation is becoming more and more serious. The survey results show that more than 90% of the newly renovated houses have the problem of excessive formaldehyde and volatile organic compound VOCs, and the multiple of the excess is 1-5 times, which is harmful to the health o...

AI Technical Summary

Problems solved by technology

[0003] The main reasons for this problem are: the concept of most people is still "decoration first, then evaluation, and then treatment", which leads to a long treatment cycle, and does not solve the problem at the source of pollution; consumers are blind when choosing decoration materials, Insufficient understanding of the emission characteristics and pollution levels of materials; there are multiple building materials used in the decoration process, and it is difficult for consumers to understand the indoor air pollution caused by building materials before decoration

[0004] At present, there are not many pre-evaluation methods for decoration pollution in my country, especially the research methods for the release of formaldehyde, VOC and other pollutants from building materials under the heating conditions of northern cold regions are rarely reported
