Pulp tableware pulping process

In order to improve the strength and other properties of pulp tableware, we use short-fiber pulp such as imported sugar cane pulp as the main raw material, and mix it with related auxiliary materials according to a certain degree of pulping and a certain concentration to form a pulp tableware raw material slurry. The preparation process of the raw material slurry is firstly a foaming slurry, and then the raw material is broken by a hydro-turbine beater to saponify the fiber to increase the fiber binding ability. During this period, it is necessary to add relevant excipients in order to improve the high temperature and water resistance of the formed pulp tableware. Finally, the concentration of the puree is adjusted horizontally to about 2% so that the puree is dehydrated and formed on the net mold.

Pulp tableware forming process

Molding is to make the raw pulp into a certain shape of the semi-wet pulp tableware blank, that is, the pulp obtained by the pulping process is dehydrated on the metal mold to form the wet pulp tableware prototype, which is the key procedure in the pulp tableware production process, the pulp About 95% of the water is removed during molding. Therefore, this process plays a decisive role in product quality, energy consumption, production efficiency, and breakage rate. The quality of the molding depends on factors such as the molding machine, the molding method, the structure and quality of the mold, and the quality of the puree.

Pulp table molding and drying process

The process of molding the special shape molding machine to remove the moisture removed from the prototype of the pulp tableware during the molding process to reduce the cost of drying and dewatering is called molding. Simultaneous molding increases the bonding force between the fibers and increases the strength of the wet paper mold. Drying is to heat and evaporate the prototype of the pulp tableware by means of preheating the upper and lower shaped pure copper mold heat to remove the remaining water after the molding of the pulp tableware, and at the same time play a sterilizing role.

Pulp tableware shaping and trimming process

The process is formed by hot stamping and calendering to eliminate the web marks left in the table forming process, so that the inner and outer surfaces are smooth and smooth. It is also possible to press some text and graphics according to different customers and usage requirements. At the same time, the burr at the edge of the quick cutlery is cut off, and the indentation which is easy to fold and open the lid is pressed.
