Free silica analyzer in dust There are many types of dust in the production environment of the power and coal industries,Mainly includes silica dust, coal dust, boiler dust, asbestos dust, cement dust, welding fumes, etc,Its characteristic is a high content of free silica in the dust,The dispersion of dust is also relatively high,Most of them are respiratory dust,Therefore, the harm to personnel exposed to dust is significant. Based on the physical and chemical properties of productive dust, concentration in the air, amount entering the human body, and the affected area,The harm caused also varies,Mainly including respiratory diseases such as rhinitis, pharyngitis, tracheitis, bronchitis, etc. The Chinese government, as well as the power and coal industry sectors, attach great importance to dust prevention work,therefore,Strengthening the detection of free silica content in dust is a very important and urgent task. Previous detection of free silica content in dust,All adopt the "Method for Determination of Dust in Workplace Air"(GB5748—85)required“Pyrophosphate gravimetric method”,This method has a series of problems such as complex operation steps, various types of reagents used, long detection cycle, poor accuracy, and strict laboratory conditions requirements,Difficult to meet the requirements of on-site batch testing.

In order to improve the accuracy of detection,To achieve the purpose of batch testing,DevelopedFC-2000DThe free silica analyzer for dust is used to detect the content of free silica in dust. To meet the needs of different customers, it has also been launchedFC-3000DFree silica analyzer in dust(The host adopts an imported spectrometer). In 2017, on the basis of the original FC-2000D, a new FC-4000D was launchedFree silica analyzer in dust, testing speed has been upgraded from the original ten minutes per sample toIn 10 seconds, the accuracy has also increased by an order of magnitude.
