【 摘 要 】

The key factors for obtaining coloured calcium silicate bricks is the high degree of dispersion and precise dosage of the colouring matter, as well as its uniform distribution in the silicate mixture. Dust particles of a colour pigment pose the most harmful effect on the health of workers at the industrial shop. In the course of components mixing, a large amount of dust from sand, lime and pigment is released into the working zone air since the process of components mixing implies materials pouring while proportioning as well as vigorous mechanical mixing. For the purpose of the quantitative and qualitative analysis of the working zone air contamination in a components mixing shops, it is necessary to investigate the dust conditions at the shop, the particle size distribution of the mixture components, the concentration of hazardous substances in the working zone air, the aerodynamic properties of dust.
