| Abstract;In the paper industry recent years, it advances toward the direction where use of recycled paper increases from the resource conservation and the rise of the concern to the environment. Recently, it is thought that a decrease in the quality of recycled paper used for domestic consumption is advanced from the thing that the recycled paper export ratio to foreign countries has risen. On the other hand, the amount of water used for papermaking is also advanced to go more closed from the environmental burden and the cost side. As a result, the development of the chemicals that demonstrates an excellent effect for such a change is demanded from the thing that is the environment that the chemicals for the extraction paper of the rise of white water electric conductivity and an increase of the number of anion impurities, etc. doesn't demonstrate the effect easily. Surface sizing agent performance is controlled by the effect of sizing of so on the internal sizing agent is understood, moreover, it is pointed out to cause the problem (It bubbles, and dirt) in operation etc. in the surface sizing though the effect corresponded to the defect by increasing the amount of use. In this lecture, the influence of the effect on internal and surface sizing agent and the design for sizing agent correspond to these changes are described. (author abst.) |
