分析了碳酸钙对PVC-U产品白度与色调的影响，讨论了控制碳酸钙白度与色调的重要性，指出了碳酸钙产品标准中白度测量方法的不足，建议采用甘茨白度或亨特白度代替蓝光白度作为PVC-U用碳酸钙白度的控制指标，以减少碳酸钙的白度与色调对PVC-U产品白度与色调的负面影响。

Influences of CaCO3 on the whiteness and laue or oi r v t.,-w V The importance of controlling the whiteness and hue of CaCO3 was discussed. Defects in the method for the measurement of whiteness of CaCO3 introduced in the product inspection standard were indicated. It was suggested that Gantz whiteness or Hunter whiteness should be adopted to substitute for the blue whiteness and to be used as the index for the control of the whiteness of CaCO3 for PVC,-U production, in order to decrease the negative effects of whiteness and hue of CaCO3 on the whiteness and hue of PVC,-U products.
