A method for measuring the key parameters of svoc release in building decoration materials

Abstract

The invention provides a method for determining the key parameters of semi-volatile organic compound (SVOC) release in building decoration materials. The method uses heating to accelerate the release of SVOC in building decoration materials, and calculates the amount of SVOC released by measuring the change of SVOC content in the material. parameters (internal diffusion coefficient D and two-phase partition coefficient K), and finally convert the key release parameters obtained under heating conditions into key release parameters at room temperature or other target temperatures according to the functional relationship between the key release parameters and temperature. The method has the advantages of simple and quick operation, short test period, accurate and reliable measurement results, and is suitable for the determination of key parameters of semi-volatile organic compound release in various building decoration materials such as leather, curtains, carpets, paints, wood, plastics, rubber, etc., and can be widely used For laboratory testing and practical engineering applications.

Description

technical field [0001] The invention belongs to the field of material analysis and environmental inspection, and mainly relates to a method for measuring key parameters of release of semi-volatile organic compounds in building decoration materials. Background technique [0002] In order to improve the use or processing performance of building decoration materials, it is often necessary to add various additives such as plasticizers, flame retardants, preservatives, softeners and antistatic agents to the materials. These additives contain a large amount of phthalo Semi-volatile organic pollutants (SVOCs) such as acid esters, polycyclic aromatic hydrocarbons, and halogenated compounds. These SVOCs are highly toxic and will be continuously released during production and use, and have become the main source of SVOCs in the environment, especially in indoor environments. [0003] The release of semi-volatile organic compounds from the inside of the material to the environment is ...
