The invention discloses a pulp spreading density adjusting system for gypsum board covering paper and a control method thereof. The pulp spreading density adjusting system comprises an upper paper density adjusting device, a first pulp distributing pipe, a second pulp distributing pipe and a lower paper density adjusting device which are arranged at a pulp spreading section of the gypsum board covering paper; and the covering paper is subjected to pulp laying and paper feeding through the first pulp distributing pipe, the upper paper pulp laying density is controlled through the upper paper density adjusting device, the covering paper subjected to paper feeding and pulp laying is subjected to pulp laying and paper discharging through the second pulp distributing pipe, and the lower paper pulp laying density is controlled through the lower paper density adjusting device. Two sets of pulp distributing pipes are led out of a mixing machine, different auxiliary materials are added at the same time, pulp is laid on upper paper and lower paper of a gypsum board, the pulp laying thickness of the pulp laying faces of the upper paper and the lower paper is adjusted through the upper paper density adjusting device and the lower paper density adjusting device, the corner density and the nail-holding power of the gypsum board are improved, up-down pulp laying and pulp laying density adjustment work of gypsum board covering paper can be completed at a time in the pulp laying working section, and the bonding performance and strength of the gypsum board are improved in a balanced mode.
Description
technical field [0001] The invention relates to the technical field of gypsum board production, in particular to a slurry density adjustment system for gypsum board face protection paper. Background technique [0002] Gypsum board is a common building decoration material. Since gypsum board is generally wedge-shaped, the thickness of the wedge-shaped edge is low and the density is small, and it is easy to overheat during the drying process, which will cause poor bonding performance of the edge protection paper and crisp edges, etc. problems, which in turn cause the problems of low strength of gypsum board and poor nail holding power. [0003] The strength and nail-holding force of gypsum board affect the joint firmness of gypsum board and keel, and adjusting the surface density and corner surface density of gypsum board can help improve the nail-holding force of gypsum board. [0004] In the existing technology, two sets of equipment are used to spread the slurry on the gyp...
