Plastic disintegration breathing apparatus

Plastic disintegration breathing apparatus

Disintegration pilot test

Conduct pilot scale experiments under composting conditions to determine the degree of decomposition of plastic materials.

■ Principle

The biological treatment of biodegradable plastic materials includes aerobic composting that meets the requirements and municipal and industrial biological waste treatment facilities. Determining the degree of decomposition of plastic materials in a pilot scale equipment is an important step in evaluating the industrial compostability test plan for this material.

●The disintegration test is conducted under determined and standardized composting conditions.

●The test materials are mixed with fresh biological waste at precise concentrations and introduced into a defined composting environment. A natural and ubiquitous microbial population spontaneously begins the composting process and temperature rise The compost clumps are regularly flipped and mixed. Regularly monitor temperature and O2 concentration.

■purpose

Determine the grade of disintegrated plastics in accordance with ISO 16929/GB/T19811 under pilot testing conditions and determined composting environment.

■explanation

●Database: Create a new or select an existing measurement database

●Measurement cycle: the time between two consecutive measurement cycles

●Sample flow: Select static or dynamic flow mode. In static mode, traffic remains constant; In dynamic mode, the flow rate is adjusted, so the output oxygen concentration is within the selected range.

●Starting flow: Set the flow rate between 0.3 and 6 liters per minute. Recommended setting is 3 liters per minute.

●Increase flow (lower limit): under the output oxygen concentration of flow regulationLimit,The lowestshouldAt around 12%, to maintain an output oxygen concentration above 10%.

●Increase flow (upper limit): The upper limit of oxygen concentration output for flow regulation should be below 20% to prevent constant maximum flow. The minimum should be 1 to 2% higher than the minimum limit.

●Flow regulation step (±): Flow change, recommended to be 0.1~0.5 liters/minute.
