PROGRESS IN NONMETALLIC MATERIALS VOC EMISSION IN AIRTIGHT CONTAINER

Nonmetallic material has been used widely on airtight container because of its superior performance.However,nonmetallic material releases VOC while being used so that it has become the largest pollution VOC source in airtight container.This article introduces the studies of nonmetallic materials VOC emission characteristics in airtight container.Depending on different types of nonmetallic materials VOC emission characteristics,summarizes normal experiential models and theoretical models,and analyzes nonmetallic materials VOC emission characteristics in airtight container.We propose several advices to build up the nonmetallic materials VOC emission model in the typical airtight container-the long-term manned space craft cabin.
