Why use a benzene concentration detector? Common toxic benzene gases in paint

Benzene: It is a highly toxic solvent, and even a small amount inhaled can cause long-term damage to the human body. Benzene can accumulate in the nervous system and bone marrow, causing damage to the nervous system and hematopoietic tissues, leading to a decrease in the number of white blood cells and platelets in the blood. Long term exposure can cause leukemia. According to research data, toluene and xylene will produce certain photoelectric reactions after entering the atmosphere, which have a certain destructive effect on the ozone layer.

During the production and painting operations in the paint warehouse, the air contains benzene compounds, which will evaporate into the air during the painting process. Benzene compounds are toxic and flammableGB6514-1995According to the Safety Regulations for Painting Operations, the hygiene standards for painting workplaces should comply withGBZ1-2002The relevant requirements in the "Hygiene Standards for Industrial Enterprise Design". The benzene volatile compounds in the air of its workshop are the largestAllowable concentration: benzene10 mg/m3, toluene100 mg/m3, Xylene100 mg/m3;So we need to install benzene detectors and gas alarm controllers to monitor the concentration of benzene volatile compounds in the paint booth at any time.

What harmful substances are in the paint

The harmful substances in paint are mainly benzene TheTVOC Total volatile organic compounds, etc., but it depends on the type of paint, such as phenolic, polyurethane, high polyester, nitro paint, etc. The most important ones are formaldehyde, heavy metals, etcTVOCBenzene substances, ethylene glycol ether solventsTDI(The Chinese name is toluene diisocyanate)Phthalate plasticizers, radon.

The East Japan Neng benzene concentration detector can24Real time online monitoring of its concentration on an hourly basis, with built-in display and sound and light alarm, conventional4-20MAandRS485Signal output, customizable wireless data transmission, high and low alarm values can be freely set. When the gas concentration exceeds the standard, it will automatically emit85dBThe above alarm sounds. Imported sensors from abroad have high accuracy, strong stability, and low error rate; Equipped with industrial grade aluminum alloy protective shell, sturdy and durable.
