Research on Absorption of Special Impregnated Paper for Plywood Formwork

Abstract:

Impregnated paper for plywood formwork is an important material for the production of plywood formwork. It was developing with plywood formwork and the market had been expanding. Absorption and wet strength are main factors which can effects on the property of impregnated paper. In this paper, mechanical chemical pulp and waste paper were used to make special impregnated paper for formwork. The ratio of EMP, dosage of aid, and operation conditions were discussed. The result showed that the absorption was improved by increasing ratio of EMP, adding agent, drying quickly, and lighter pressure. A certain ratio of AOCC is necessary to ensure strength. The paper also discussed the difference of white spot between bamboo plywood formwork and plywood formwork which indicated that white spot caused by waste paper .However, it wasn’t damage the quality of structures.
