[0002] Paperboard is the filter medium of deep filter, in the manufacturing process of paperboard, vacuum sheeting is one of the main ways of paperboard manufacturing. The specific steps of vacuum sheeting are as follows: after the fiber is beaten, standard defibration and beating are carried out, the paper pulp after beating is poured into the sheeting barrel, after stirring the paper pulp, rapid filtration forming is carried out to make wet paperboard, and then the wet paperboard is dried to make paperboard.
[0003] The thickness of paperboard is one of the important parameters of paperboard, and the paperboard used for filtration generally has specific thickness requirements. On the one hand, the thicker thickness of paperboard can increase the pollution capacity in the filtration process, increase the contact time of the material liquid and the paperboard, and increase the adsorption effect of the paperboard on impurities. On the other hand, for paperboard with the same grammage, too thick thickness of paperboard will affect the tightness of paperboard, and the paperboard will be more fluffy, which will reduce the tensile strength of paperboard and reduce the strength of paperboard against external force. Therefore, in order to ensure the pollution capacity and tightness of paperboard at the same time, the thickness of paperboard needs to be accurately controlled. The surface texture of paperboard can reflect the roughness of the surface of paperboard. According to the process requirements of paperboard, the roughness of the surface of paperboard is different, and the roughness of the surface of paperboard needs to be determined according to the use of paperboard. Therefore, the surface texture of paperboard needs to be controlled in the paperboard forming process. In addition, each manufacturer also designs specific surface patterns to distinguish the paperboard of other manufacturers.
[0004] The prior art mainly uses the following methods to control the thickness of wet paperboard:
[0005] (1) The thickness of wet paperboard is controlled by controlling the amount of paper pulp.
