Standard plate for detecting pollution release of decoration material as well as preparation and application of standard plate

Abstract

The invention discloses a standard plate for detecting pollution release of a decoration material as well as preparation and application of the standard plate. The standard plate comprises a sealing outer sleeve, a wood plate assembly, a sealing upper cover and a sealing plug, a hole is formed in the bottom surface of the sealing outer sleeve, and the wood plate assembly is composed of a bottom plate, a core plate and a top plate, nested in the sealing outer sleeve and pressed and fixed by the sealing upper cover; the core plate contains a porous material, and radial channels are formed in the core plate; through holes are formed in the centers of the top plate and the sealing upper cover; a sealing plug is inserted into the through holes for sealing. When the standard plate is used, target pollutants are dropped into the through holes, and the target pollutants are diffused and dispersed into the porous material and other interstitial substances in the core plate through the channels by centrifugation and oscillation, so that the standard plate capable of uniformly and stably releasing the target pollutants is obtained. By changing the types and concentrations of the added target pollutants, the pollution release conditions of different product control materials can be detected.

Description

technical field [0001] The invention relates to a standard product for verifying the pollution performance of decoration materials, in particular to a standard product of wood board that simulates a normal synthetic board structure and can stably and persistently release target concentrations and types of volatile organic compounds, and is used for verifying the detection and control of material pollutant release. The performance of the product belongs to the technical field of indoor pollution control. Background technique [0002] The health effects of various indoor volatile pollutants on the human body have attracted more and more attention in recent years. For example, chronic exposure to formaldehyde has been shown to be closely associated with neurological impairment, asthma, allergies, liver damage, pulmonary edema, cancer of various organs, and leukemia; chronic exposure to benzene may lead to dramatic changes in lymphocyte levels, and even subsequent Various types...

Problems solved by technology

[0009] (2) Even for decoration materials of the same type, manufacturer, and batch, due to production scheduling arrangements, the pollution content and release rate between batches are also different, so use the effect of actual decoration materials to evaluate and compare different pollution control products performance, it may be due to differences in materials used, resulting in inaccurate evaluation results

[0010] (3) The types of pollutants released by the actual decoration materials are uncontrollable and cannot be used to verify the performance of controlled products for targeted elimination of special pollutants

[0011] (4) The pollutant release gradient of actual decoration materi
