The invention relates to a composting box for measuring the disintegrating degree of a polymeric material. The composting box comprises a box body, a material frame, a water tank and an air blowing system, wherein the material frame is placed at the middle part of the box body and used for placing the polymeric material; the water tank is arranged at the bottom of the box body and used for providing water; a supporting frame is arranged at the middle part of the box body; the material frame is placed on the supporting frame; the air blowing system comprises a fan, an air supply coiled pipe and an air blowing pipe which are connected with one another sequentially; the air supply coiled pipe passes through the water tank; the air blowing pipe is arranged at the bottom of the material frame; a heating device is arranged in the water tank to guarantee that the temperature in the experiment process meets requirements. Compared with the prior art, the composting box provided by the invention can simulate the conditions of the natural world well, can meet the conditions of temperature, water, oxygen content, pH and the like required by disintegration of the polymeric material, can effectively measure the disintegrating degree of the polymeric material, takes the use convenience of an operator into consideration, reduces labor intensity and is convenient to clean.
Description
technical field [0001] The invention relates to the field of degradation testing, in particular to a compost bin for measuring the disintegration degree of polymeric materials. Background technique [0002] With the development of the times, people pay more and more attention to the environment. Soil pollution is one of several common pollutions, including inorganic pollution and organic pollution. Inorganic pollution mainly refers to soil acid-base pollution or heavy metal pollution. Second organic pollution mainly refers to non-degradable organic substances in soil. These difficult-to-degrade organic substances are generally polymeric materials. Therefore, the degradation of polymeric materials must be considered during the production process. If it is a refractory material, its production must be reduced or stopped to reduce the cost of post-pollution treatment. However, the disintegration test of polymeric materials is difficult, and there is no device for measuring th...
