Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "vertical", "horizontal" etc. used in this specification is based on the orientation or positional relationship shown in the drawings, It is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the device or element referred to must...

Abstract

The embodiment of the invention provides an emission detection device, which comprises a cover body, a sealing ring and a sensor, wherein the cover body defines a first accommodating space for accommodating an emission emitted by a to-be-detected material; the sealing ring is arranged on the cover body and is used for forming sealing between the cover body and the surface covered by the cover body; and the sensor is arranged on the cover body and is used for detecting the emission in the first accommodating space. According to the emission detection device provided by the embodiment of the invention, the cover body and the sealing ring can be buckled on the surface of the material to form the closed cavity, so that an environment cabin can be replaced, air with temperature and humidity controlled does not need to be continuously introduced, and pollutants emitted from the surface of the material can be quickly accumulated in the closed cavity, and a concentration curve of pollutants accumulated for a certain period of time is detected by utilizing a sensor in the cavity. Furthermore, the highest concentration rising curve slope can be calculated according to the concentration curveand converted into the material pollution emission rate. In the way, the embodiment of the invention can screen and judge whether the pollution emission rate of the material meets the requirement ornot.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of detecting the environmental protection performance of materials, and in particular, relate to an emission detection device. Background technique [0002] In newly renovated rooms, the pollution emission of materials such as building decoration and decoration is the main cause of indoor air pollution problems, and the pollutants emitted in the indoor air can be called emissions or volatiles. In decoration projects, it is very important to detect and control the pollution emission performance of materials. [0003] At present, the commonly used material pollution emission detection method is the environmental chamber method, which includes: putting the material into the environmental chamber, simulating the situation of the real room by the environmental chamber, and measuring the pollution concentration in the environmental chamber, so as to characterize the pollution emission perform...
