水泥粉尘的比电阻及其测量之二

SPECIFIC RESISTANCE OF CEMENT DUST ANDITS MEASUREMENT (Ⅱ)

水泥粉尘经分级，并经吸湿和吸油处理，对所得尘样分别测定比电阻，从而找出湿度等对比电阻的变化规律、分析其产生原因，为改进和合理使用电除尘器提供依据。

ement dust is classified into different particulate sizes followed by de--oiling and dehumidi-fication treatment. Specific resistances of dust samples are measured individually. Correlation ofspecific resistance with humidity or oil is found. Data obtained could provide parameters for im-proving and effective operation of the electrostatic precipitator.
