Embodiment Construction
[0028] The invention combines papermaking production with cylinder screen printing, performs online screen printing in the existing paper production process, and realizes online screen printing for continuous paper production. The specific process steps are as follows
[0029] pulping. Garden net papermaking forming. press. Pre-dry. Surface sizing, surface sizing can be trough sizing, roller sizing or spraying, etc. The trough sizing process is simple and low in cost. Air cushion drying, hot air drying can be used for drying, but UV curing is generally used, which has high drying efficiency, short time, less water loss for online paper production, and small footprint. Soft calendering. Moisture scan detection. Printing process: There are two links of printing and drying. Specifically, printing processes such as screen printing, offset printing, gravure printing or missing printing can be used. Carry out roll paper and put it into storage. Before rolling the paper, it c...
