High Quality for Duplex Paper Machine - Gypsum Board Paper Making Machine – Dingchen

1. Low weight: Gypsum board paper weight is only 120-180g/ m2, but it has very high tensile strength, which perfectly meets the requirements of high-grade gypsum board production. The board produced with gypsum board paper has very high performance in surface flatness, which makes it the best protective material for the production of large and medium-sized high-grade gypsum board.

2. High air permeability: Gypsum board paper has very large breathing space, which allows more water evaporation during the drying process of gypsum board production. It helps to increase production capability and efficiency.

3. Great heat permeability resistance: Gypsum board paper is more convenient for the control of shaping, slitting and turnover in gypsum board production, in production process, gypsum board paper keeps it’s strength and wetness, which helps to improve the yield of board production line.
