Free silica analyzer in dust

Free silica analyzer in dustThere are many types of dust in the production environment of the power and coal industries, mainly including silicon dust, coal dust, boiler dust, asbestos dust, cement dust, welding fumes, etc. Its characteristics are that the content of free silica in the dust is high, and the dispersion of the dust is also relatively high, which is mostly respiratory dust. Therefore, it poses a greater risk to personnel exposed to dust. According to the physical and chemical properties of productive dust, the concentration in the air, the amount of dust entering the human body, and the affected areas, the hazards produced also vary, mainly including respiratory diseases such as rhinitis, pharyngitis, tracheitis, bronchitis, etc. The Chinese government, as well as the power and coal industries, attach great importance to dust prevention work. Therefore, strengthening the detection of free silica content in dust is a very important and urgent task. In the past, the detection of free silica content in dust was carried out using the "pyrophosphate gravimetric method" specified in the "Method for Determination of Dust in Workplace Air" (GB5748-85). This method has a series of problems such as complex operating steps, a wide variety of reagents used, long detection cycles, poor accuracy, and strict laboratory conditions, which make it difficult to meet the requirements of on-site batch testing. In order to improve the accuracy of detection and achieve the purpose of batch detection, the FC-2000D free silica analyzer for dust has been specially developed to detect the content of free silica in dust. To meet the needs of different customers, the FC-3000D (using * host) has also been launched Imported models have advantages such as high precision, faster speed, and more powerful software functions.
