Problems solved by technology

However, the instruments used in this standard are relatively vague. At present, there is no relevant supporting testing equipment patent. Therefore, in order to help testing institutions carry out degradable testing and inspection activities, it is necessary to develop a degradable performance tester.

Embodiment Construction

[0024] Such as Figures 1 to 3 shown

[0025] The degradable testing device includes an air supply mechanism 100, a degradable testing mechanism and a processor.

[0026] Air supply mechanism 100 comprises air compressor 110, anti-suckback bottle 120, carbon dioxide filter bottle 130 and diverter 140, and the outlet of air compressor 110 is communicated with the inlet of anti-suckback bottle 120 by pipeline, and the inlet of anti-suckback bottle 120 The outlet communicates with the second intake pipe 131 of the carbon dioxide filter bottle 130, and the carbon dioxide filter bottle 130 has Ca(OH) in it 2 solution (depositing NaOH solution in the carbon dioxide filter bottle 130 can also reach the same effect), and the second inlet pipe 131 of the carbon dioxide filter bottle 130 stretches into Ca(OH) 2 In the solution, the carbon dioxide filter bottle 130 communicates with the inlet of the splitter 140 through the second air outlet pipe 132, the carbon dioxide filter bottle 1...

Abstract

The invention provides a degradability testing device under a controlled composting condition. The device comprises an air supply mechanism, a degradable testing mechanism and a processor, an outlet of an air compressor of the air supply mechanism is communicated with a flow divider through a pipeline, and compressed air generated by the air compressor is input into the flow divider. The degradable testing mechanism is divided into a sample testing assembly, a reference sample testing assembly and a blank testing assembly, each group of testing assembly comprises a reaction kettle, a stirrer, a carbon dioxide sensor and a transmission module, the reaction kettle is communicated with the flow divider through a first air inlet pipe, and a heating device for heating the reaction kettle is arranged outside the reaction kettle; a stirring rod of the stirrer extends into the reaction kettle; the reaction kettle is communicated with a gas inlet of the carbon dioxide sensor through a first gas outlet pipe; the processor receives signals transmitted by the transmission modules of the multiple groups of testing assemblies. The device completely meets the GB/T 19277.1-2011 standard, and the final aerobic biological decomposition capability and disintegration degree of a test material are measured under the simulated strong aerobic composting condition.

Description

technical field [0001] The invention relates to a degradable test device under controlled composting conditions. Background technique [0002] Bio-based materials are a class of new materials synthesized by biological or chemical methods using renewable resources as raw materials. They focus on the biological origin and renewability of raw materials. They are an important direction for current synthetic materials. , resource conservation and other characteristics, known as the "leading industry" to create green GDP, has become a strategic focus of governments at all levels to vigorously support development. [0003] On November 2, 2020, Anhui Province issued the "Implementation Plan for Further Strengthening Plastic Pollution Control in Anhui Province", which clearly states that by the end of 2020, it will take the lead in banning and restricting the production, sales and use of some plastic products in some regions and fields. By 2022, the consumption of disposable plastic...
