Problems solved by technology

Usually the temperature of the high-temperature fixing roller is 180 to 190 degrees Celsius. After the paper is baked by the fixing roller at high temperature, it will expand due to the thermal effect and heat-set. This process usually causes the paper to warp after copying. Paper jams, difficulty in binding pages after copying, ugly appearance, etc.

Abstract

The invention relates to a Production method for paper warping control, production equipment and paper. The method comprises steps of mixing raw material pulp added with chemimechanical pulp, diluting the raw material pulp into flow pulp, dehydrating the flow pulp in the forming net to form a paper sheet, and controlling the dehydration amount difference value of two sides of the paper sheet to be not greater than a first preset difference value, enabling the dewatered paper sheet to be squeezed and then subjected to first drying, and conducting heat setting on the first face of the paper sheet, gluing at least one surface of the paper sheet, and calendering to obtain the paper. According to the method, the warping deformation of a paper sheet product due to external influence is reduced, and the warping effect of the copy paper in the thermal fixing process is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of papermaking, and in particular to a production method, production equipment and paper for controlling paper warpage. Background technique [0002] The current laser printing and copying technology uses static electricity to absorb toner on the copy paper according to the target image, and then melts the toner on the surface of the paper through a high-temperature fixing roller to form a firm image. Usually the temperature of the high-temperature fixing roller is 180 to 190 degrees Celsius. After the paper is baked by the fixing roller at high temperature, it will expand and heat-set due to the thermal effect. This process usually causes the paper to warp after copying. Paper jams, difficulty in binding pages after copying, ugly appearance, etc. [0003] Therefore, this application proposes a production method, production equipment, and paper for paper warpage control, so as to reduce the warpage...
