A PAPERMAKING PROCESS OF INCREASING ASH CONTENT OF A PAPER PRODUCT AND A PAPER PRODUCT OBTAINED BY THE SAME |
摘要 |
Provided is a papermaking process of increasing ash content of a paper product, comprising: adding a flocculant to a mixture comprising filler particles and water, wherein the flocculant has a reduced specific viscosity of 5-16dL/g, a molecular weight of greater than or equal to 1,200,000 and less than or equal to 7,500,000, and 5-50mol% of cationic charge; whereby a size distribution of a flocs formed by a flocculation of the filler particles and the flocculant has a median particle size in a range of 10μm to 150μm; wherein the filler is not precipitated calcium carbonate alone. Also provided is a rotating mixing apparatus used in the papermaking process. |
