Hanwen Fully Automatic Free Silicon Dioxide Treatment Instrument

——Pyrophosphate method

1Research and Development Prospects

The air environment in daily workplaces contains various types of dust, mostly respiratory dust. Dust containing free silica can easily cause various pneumoconiosis diseases and seriously endanger human health when inhaled. The higher the content of free silica in dust, the greater the harm to human health. Therefore, long-term control and monitoring of the content of free silica in air dust is particularly important. In the assessment and comparative experiments of occupational health blind samples, the determination of free silica content is also a mandatory item.

According to the national occupational health standard GBZ/T 192.4-2007 "Determination of Dust in Workplace Air Part 4: Free Silica Content" of the People's Republic of China, Shandong Hanwen Instrument has developed and researchedFully automatic free silica analyzerProcessing platform. There are three recommended methods for determining free silica in the standard, namely: pyrophosphate method, X-ray diffraction method, and infrared spectrophotometry method. Among them, the pyrophosphate method, as the first method, is the best analysis method for free silica.

two、Instrument Introduction

Fully automatic free silica analyzer/processorIt is a pre-treatment instrument used to determine the content of free silica in air dust in public places. The entire process is fully automated according to the national standard method; The instrument can achieve large-scale productionautomaticPreparation of pyrophosphate,Easy to operate, reduces labor intensity, eliminates the need for personnel to be on duty throughout the entire process, and safeguards the physical and mental health of experimental personnel.
