Abstract

Disposable plaster tableware, including chopsticks, spoons, lunch boxes, cups, bowls, plates. It is mainly made of gypsum and water-soluble adhesives through tableware molding technology. It includes the following raw materials in percentage by weight: 60-97% of gypsum powder, 3-40% of water-soluble adhesive, and the water-soluble adhesive is selected from polyvinyl alcohol resin, starch, gelatin, modified polyethylene, organic silicon A combination of one or two or more binders. In addition, 25-40% of water accounting for the total weight of the gypsum powder and the water-soluble binder is added. Its utensils have a waterproof coating on the surface. Gypsum chopsticks raw materials: gypsum powder 71-84%, polyvinyl alcohol resin 4-15%, starch 3-7%, talcum powder 3-7%, fiber 0-8%; add water accounting for 30% of the total weight of the above raw materials . The gypsum chopsticks of the present invention are free from bending and deformation, comfortable to the touch, practical and hygienic, and can be made into high, medium and low grade varieties. Gypsum is an edible natural non-toxic and harmless raw material with low manufacturing cost. It will not cause pollution and damage to the environment after being used and discarded.

Description
