Study of Culture Paper Making with P-RC APMP by Different Papermaking Process

Abstract:

Using Poplar P-RC APMP as raw materials for culture paper making, the effect of conventional papermaking process and P-RC APMP fines-calcium carbonate co-flocculation process on the P-RC APMP culture paper properties were studied. The result showed that, comparing to the conventional papermaking process, co-flocculation process can supply paper with better strength properties, bulk and whiteness. When precipitated calcium carbonate (PCC) or ground calcium carbonate (GCC) were added respectively in conventional papermaking process, the PCC supplied handsheets with better bulk and whiteness, while GCC supplied handsheets with better strength properties. In the co-flocculation process, the effects of PCC and GCC were nearly the same in strength properties and bulk of handsheets, but PCC was more beneficial for whiteness. SEM images showed that PCC distributed more evenly in the fiber network, and well-bonded with fiber network. The particle size of GCC is relatively small, mainly filled in the fiber network and wrapped on the fiber.
