研究硅酸钙填料(FACS)对AKD浆内施胶的影响,并对施胶障碍的产生原因进行了分析。结果表明:FACS用量的增加能够增大纸页的吸水值;硅酸钙加填纸页的吸水值随AKD用量的增加而逐渐降低,但总体上FACS的Cobb值高于PCC和GCC;利用紫外-分光光度法研究FACS对施胶剂AKD的吸附,发现FACS对AKD的吸附量和吸附率较高且远大于PCC和GCC填料。在考察用量范围内,FACS对AKD的吸附率在43.9%～88.4%之间,GCC对AKD的吸附率在1.09%～29.9%之间,PCC的吸附率在13.6%～35.1%之间,FACS加填纸施胶障碍的产生,主要是由于FACS填料对AKD施胶剂有较强的吸附性。
The effect of calcium silicate filler (FACS) on the sizing of AKD slurry was studied, and the cause of sizing disorder was analyzed. The results showed that: the increase of FACS dosage can increase the water absorption value of paper; the water absorption value of calcium silicate plus paper pad decreases with the increase of AKD dosage, but the Cobb value of FACS is higher than that of PCC and GCC as a whole; - Spectrophotometric Determination of AKD sizing agent FACS adsorption and found FACS AKD adsorption capacity and adsorption rate higher and much larger than the PCC and GCC packing. The adsorption rates of AKD by FACS ranged from 43.9% to 88.4%, the adsorption rates of AKD to GCC ranged from 1.09% to 29.9% and the adsorption rates of PCC ranged from 13.6% to 35.1% Adding filler sizing disorders, mainly due to FACS filler AKD sizing agent has a strong adsorption.
