Abstract

The invention discloses a paint concentration detecting device which comprises a machine body, wherein an air inlet pipe is fixed to the upper surface wall of the machine body; a warning light, a liquid crystal display, a control button and an alarm are arranged on the front surface wall of the machine body from top to bottom in sequence; an induced draft fan is arranged inside the machine body; afan impeller arranged inside the induced draft fan is fixedly connected with a main shaft of an air guiding motor; the air guiding motor and the machine body are fixedly connected by a motor fixing frame; an induced draft pipe fixed on the right surface wall of the induced draft fan and a color developing agent solution bottle are tightly connected by using a rubber plug; an infrared laser component arranged on the left side of the color developing agent solution bottle and the machine body are fixedly connected by an infrared laser component fixing bracket. The infrared laser component is arranged inside the paint concentration detecting device for irradiating a color developing agent solution with an infrared laser, so that the detection time is short, the reaction is carried out in onestep and the result is accurate, and other gases do not interfere with the detection.

Description

technical field [0001] The invention relates to the technical field of paint, in particular to a paint concentration detection device. Background technique [0002] Formaldehyde is a volatile organic compound with many pollution sources and is one of the main pollutants in the indoor environment. The formaldehyde content of indoor air stipulated by the state shall not exceed 0.08mg / m3. If formaldehyde is excessive in the air, it will seriously endanger human health. Formaldehyde is colorless and odorless, so it is not easy to be detected by people, so it needs to be measured with the help of instruments. [0003] There are currently four main methods for detecting formaldehyde. (1) Electrochemical detection method, formaldehyde undergoes an oxidation reaction at the electrode through a highly gas-permeable ionic membrane, and the generated current is proportional to the concentration of formaldehyde. The working baseline of this method is unstable, and is greatly affecte...
