Formaldehyde or VOC release amount test and pretreatment simple cabin

Abstract

The invention discloses a formaldehyde or VOC release amount test and pretreatment simple cabin including a cabin body; a cabin body door, an air inlet and an air outlet are arranged on the cabin body. The outer wall of the cabin body is equipped with at least one semiconductor refrigeration piece or liquid thermoregulation jacket which is capable of refrigerating and / or heating, the interior of the cabin body is equipped with a stirring fan, the outer wall of the cabin body is equipped with a temperature sensor located in a heat conduction zone of the semiconductor refrigeration piece or usedfor the liquid thermoregulation jacket to measure the temperature, the interior of the cabin body is equipped with a temperature and humidity sensor, and the exterior of the cabin body is connected with a filter air flue communicating with the interior of the cabin body; the filter air flue is equipped with an air inlet switch valve, an air outlet switch valve, a filter device and a filter fan. The cabin is simple in structure and low in cost, can provide the constant-temperature and / or constant-humidity clean cabin body with controllable temperature, relative humidity and background concentration, provides a stable standard test environment for testing and avoids the influence of environmental factors or other uncertain factors on test results.

Description

technical field [0001] The invention relates to the technical field of testing equipment, and more specifically, relates to a formaldehyde or VOC emission testing and pretreatment simple cabin. Background technique [0002] Formaldehyde, volatile organic compounds (VOC) and other volatile harmful gases that exist in existing materials such as furniture and automotive supplies will cause harm to the human body if the concentration of volatile harmful gases exceeds a certain range. Reasonable collection of formaldehyde, VOC and other volatile harmful gases in materials is one of the important links of detection technology. [0003] At present, there are also many equipments for testing the release of volatile harmful gases such as formaldehyde and VOC in the industry, but the existing testing equipment has the following shortcomings: 1. The structure is complex and the cost is high; 2. The temperature of the surrounding environment, Environmental factors such as humidity and ...
