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 present disclosure relates to a production method, production equipment, and paper for paper warpage control. Raw material pulp added with chemical mechanical pulp is mixed; the raw material pulp is diluted into flow pulp; The difference of the dewatering amount is not greater than the first preset difference; the dehydrated paper sheet is pressed into the first drying process, which is heat-set on the first side of the paper sheet; at least one surface of the paper sheet is coated with glue; calendered into paper. The present application reduces the warpage deformation amount of the paper product itself affected by the outside world, and reduces the warpage effect of the copy paper during the thermal fixing process.

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 paper warpage control. Background technique [0002] In current laser printing and copying technology, the toner is electrostatically adsorbed on the copy paper according to the target image, and then the toner is melted on the surface of the paper sheet by a high-temperature fuser roller to form a firm image. Usually the temperature of the high-temperature fixing roller is 180 to 190 degrees Celsius. After the high-temperature baking of the fixing roller, the paper will expand due to thermal effect and heat-setting. This process usually causes the paper to warp after copying. Paper jams, difficult binding of paper pages after copying, and unsightly appearance. [0003] Therefore, the present application proposes a production method, production equipment, and paper for paper warpage control, so as to redu...
