Degradable disposable paper pulp tableware and manufacturing method thereof

Abstract

The invention relates to the field of production of vegetation fiber tableware, in particular to degradable disposable paper pulp tableware and a manufacturing method thereof. The tableware consists of the following raw materials in percentage by weight: 20 to 70 percent of mechanical wheat straw pulp oven dry stock, 20 to 70 percent of cane syrup oven dry stock, 5 to 10 percent of softwood pulp oven dry stock, an oil-proofing agent in an amount which is 0.9 to 1.2 percent of the total weight of the mechanical wheat straw pulp oven dry stock, the cane syrup oven dry stock and the softwood pulp oven dry stock and a waterproofing agent in an amount which is 5 to 8 percent of the total weight of the mechanical wheat straw pulp oven dry stock, the cane syrup oven dry stock and the softwood pulp oven dry stock. The manufacturing method comprises the following steps of: soaking a mechanical wheat straw pulp plate, a cane syrup plate and a softwood pulp plate by using water; pulping by using a pulping machine until all the pulp plates are completely and uniformly changed into fibers; putting pulp liquid into a pulp batching pool; diluting by adding water; adding the waterproofing agent and the oil-proofing agent; conveying the pulp liquid into a quantification cup of a forming machine by using a pulp pump; after the quantification cup is fully filled, placing a 40-60 mesh screen mesh on a forming die; adsorbing under vacuum to form a wet pulp blank by using the forming machine; transferring the formed wet pulp blank into a hot-press mold of a setting machine by using the mesh screen; pressing the wet pulp blank to be dry by using temperatures, wherein irregular edges are arranged outside a set product; and removing irregular burrs to ensure that the excircle of the product is smooth and neat.

Description

Technical field [0001] The invention relates to the production field of plant-wood fiber tableware, in particular to a degradable disposable paper pulp tableware and a manufacturing method thereof. Background technique [0002] As we all know, in addition to plastic products, the disposable pulp tableware currently used on the market also has pulp products. Because plastic products are difficult to recycle and cause serious white pollution, the relevant departments have banned their large-scale use; pulp products as alternative products are generally made of tree pulp. Due to the high manufacturing cost, paper-making pollution and competition for raw materials with paper products, it is also difficult to promote and use. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned existing technical deficiencies and provide a degradable disposable paper pulp tableware and a manufacturing method thereof, using wheatgrass, bagasse, etc. a...
