Three, product principle

In this experiment, the final aerobic decomposition capacity and disintegration degree of bio-based materials were measured by simulating aerobic composting.

Under the action of microorganisms, bio-based materials consume oxygen to decompose and produce inorganic materials such as carbon dioxide and water. The carbon dioxide produced is monitored in real time by high-precision infrared sensors. The biodegradation rate is the percentage of the actual carbon dioxide release of the sample and the theoretical carbon dioxide release of the sample.

When the experiment is over, it can be used to determine the disintegration degree of the experimental material and also to measure the mass loss of the experimental material.

Six, experimental examples

According to GB/T19277.1-2011 method standard, the test period is 70 days. As can be seen from Figure 1, the cellulose degradation rate reaches 81.88% within 45 days. Within 70 days, the degradation rate of cellulose reached 98.18%. At this time, the growth of each experimental group basically ended and the curve was flat.
