对一种杨木PRC-APMP商品浆进行后打浆处理,探讨其配抄对铜版原纸性能的影响。结果表明,打浆处理降低了纤维束含量,提高了浆料的强度性能,但其滤水变慢,把打浆度提高到45°SR对配抄铜版原纸是合适的。PRC-APMP配抄铜版原纸时,需要重点关注浆料滤水、系统阳离子需要量、印刷表面强度、纸页表面遇水粗化等方面的问题。浆料的配比NBKP∶LBKP∶PRC-APMP=40∶30∶30时,可以抄造出合格的铜版原纸。
After a poplar PRC-APMP commercial pulp beating beating treatment to explore the copy on the copper-based base paper performance. The results showed that beating treatment reduced the content of fiber bundles and improved the strength properties of the slurry. However, the water filtration slowed down and the beating degree was improved to 45 ° SR. PRC-APMP Copying copper-based base paper, you need to focus on slurry drainage, system cation requirements, the printing surface strength, surface roughness of the paper surface and other issues. Slurry ratio NBKP:LBKP:PRC-APMP = 40:30:30, you can copy the papermaking qualified copperplate.
