Embodiment Construction

[0015] Film transfer among the present invention realizes the method for coating microcapsules and comprises: a. coating roll 15 runs, and coating roll 15 speeds reach running speed, and when paper tail draws through coater, open full-width spray water 10, cylinder Drive 8 actions to close the beam to make the metering rod 2 and the coating roller 15 fit together, the metering rod 2 rotates, the loading air bag 5 is pressurized to force the feeding pipe 6 to apply microcapsule coating to the roller surface, b. When the feeding pressure is stable and the roller surface When the coating layer is uniform, turn on the side spray water 12 to spray the roller surface, c. After the paper is placed in the full width of the coating machine, the two coating rollers are bonded together, and the full width spray water 10 is hit to the automatic position, d. The cloth amount banner curve is adjusted by the fine-tuning mechanism 4, and the air bag 5 is loaded to pressurize to adjust the coat...

Abstract

The invention discloses a novel method for coating microcapsules, and particularly relates to a method for realizing coating for microcapsules by film transfer. The method disclosed by the invention comprises the following steps of: a, running coating rolls and achieving a running speed, when the tail of paper is led through a coating machine, turning on full-width spraying water, driving an acting combined beam by a cylinder, rotating a metering rod, pressurizing by a loading air pocket, and charging a microcapsule coating by a charge tube; b, when a loading pressure is stable and coating layers on the surfaces of the rolls are uniform, and turning on edge-spraying water; and c, after paper is spread with a full width on the coating machine, bonding the two coating rolls, turning on the full-width spraying water to an automatic position, and adjusting a coating weight according to a coating weight horizontal curve, and via the adjustment of a fine adjustment mechanism and the pressurization of the loading air pocket. The method disclosed by the invention has the advantages that control on the coating weight is stable; the coating weight is convenient and fast to adjust by the fine adjustment mechanism; and a coating solid content is high, so that a requirement on the drying capacity after coating is low, thus reducing steam consumption, and the production cost of per ton of paper.

Description

technical field [0001] The invention introduces a new method for coating microcapsules, in particular relates to a method for coating microcapsules by film transfer. Background technique [0002] Coupled carbonless copy paper can be divided into: upper paper (CB paper), that is, the back of the paper is coated with a paint containing a color-developing agent; middle paper (CFB paper), that is, the front of the paper is coated with a paint that contains a color The coating of the color agent; the lower paper (CF paper) is coated with the coating containing the color developer on the front side of the paper. The color development mechanism of carbon-free copy paper is: when the good carbon-free copy paper is subjected to external pressure, the microcapsules coated on the bottom of the upper layer of paper are broken. , the colorless dye liquid in the microcapsules flows out and contacts the color developer on the front of the next layer of paper, reacts and develops color, an...
