By creating a water-based foam system, the "liquid sealing effect" of water and the "detour effect" of forming foam are used to provide a "mass transfer barrier" for the volatile gases in the matrix to inhibit the escape of volatile gases. In addition, the highly permeable foam can infiltrate the soil and degrade and repair pollutants in the soil. This product can inhibit VOCs emissions during its validity period, and can maintain a VOCs barrier rate of 95% for more than 17 hours while excluding interference from temperature, wind intensity and humidity. The half-life of the material is increased to more than 10 hours, and the barrier time t90 when the barrier ratio is higher than 90% is greater than 8h, and t80 is greater than 12h. Controls the spread of volatile organic pollutants or odors. Compared with traditional HDPE film barriers, it reduces carbon by 10.5kg/month per square of barrier, and has a pollutant restoration effect that traditional barrier materials do not have.
