Abstract: A process for making cellulose hardboard in which a wet lap of cellulose fiber containing in excess of 25 percent water is subjected to a hot press at an initial high pressure step of 200 to 500 psi. The said cellulose fibers are then subjected to at least one intermediate pressure step of 60-150 psi to reduce the moisture content to less than 20 percent and finally subjecting the said cellulose fibers to a final pressure step of 5-20 psi to reduce the moisture content greater than 5 percent.
Abstract translation: 制造纤维素硬纸板的方法,其中在200-500psi的初始高压步骤中,将含有超过25%水的纤维素纤维的湿卷层压经受热压。 然后将所述纤维素纤维进行至少一个60-150psi的中间压力步骤,以将水分含量降至小于20%,最后使所述纤维素纤维进行5-20psi的最终压力步骤以降低水分 内容大于5%。
