Product principle

This experimental system simulates the aerobic composting conditions of bio-based materials, and determines their final aerobic decomposition capacity and disintegration degree.

Bio-based materials, under the action of microorganisms, consume oxygen to decompose and produce carbon dioxide, water and other inorganic substances. The generated carbon dioxide is monitored in real time by high-precision infrared sensors. The percentage of the actual carbon dioxide release of the sample and the theoretical carbon dioxide release of the sample is the biodegradation rate.

At the end of the experiment, it can be used to determine the degree of disintegration of the experimental material, and also to determine the mass loss of the experimental material.

Examples of experiments

This is the experimental result of a unit using M1200 compost method biodegradation instrument to test the biodegradability of a sample with reference to the method standard of GB/T19277.1-2011. The test period is 70 days. It can be seen from Figure 1 that the degradation rate of cellulose in 45 days reaches 81.88%, and the degradation rate of cellulose in 70 days reaches 98.18%. At this time, the growth of each experimental group is basically over, and the curve is flat. The experimental design is shown in the following table:
