Embodiment

[0010] Embodiment: a kind of molding process that utilizes waste paper trim, operation steps are as follows:

[0011] (1) Take raw materials according to the following weight ratio: 12-18% of paper trim, 5-8% of dilute hydrochloric acid, 74-83% of water, crush and stir the above-mentioned raw materials with a pulper; add water to adjust to 0.8%- 2.9% pulp reserve;

[0012] (2) Make a mold according to the shape of the statue, align the upper and lower molds accurately, clamp it on the molding machine with a fixture, turn on the equipment, start the equipment to suck the pulp into the mold, the pulp is vacuum adsorbed on the lower mold, and the water is vacuumed After pulling out, close the lower mold and upper mold, and then take off the formed product;

[0013] (3) Put the demoulded product into the drying line for drying, heat the hot-press shaping mold with the same shape as the product to 120-220 degrees, heat-press and shape the product for 4-12 seconds, and then take ou...

Abstract

A molding process utilizing waste paper scraps, the operation steps are as follows: (1) Weigh raw materials according to the following weight ratios: 12-18% of paper scraps, 5-8% of dilute hydrochloric acid, 74-83% of water, The above raw materials are crushed and stirred with a pulper; then add water to adjust to 0.8%-2.9% pulp for later use; (2) Make a mold according to the shape of the statue, align the upper and lower molds accurately, and clamp them on the molding machine with clamps , turn on the equipment, start the equipment to suck the pulp into the mold, the pulp is vacuum adsorbed on the lower mold, the water is vacuumed off, the lower mold and the upper mold are closed, and then the formed product is taken off; Put the product into the drying line to dry, heat the hot-press shaping mold with the same shape as the product to 120-220 degrees, heat-press and shape the product for 4-12 seconds, and then take out the product.

Description

technical field [0001] The invention belongs to the technical field of waste paper treatment, and in particular relates to a molding process using waste paper trim. Background technique [0002] Existing sculpture works of art generally adopt materials such as stone, wood, and jade to be sculpted. This type of sculpture has the disadvantages of high labor intensity, long time consumption and high processing cost during processing. In addition, the existing sculptures have a single color. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a molding process utilizing waste paper trim. [0004] The present invention is realized through the following technical solutions: [0005] A molding process utilizing waste paper trim, the operation steps are as follows: [0006] (1) Take raw materials according to the following weight ratio: 12-18% of paper trim, 5-8% of dilute hydrochloric acid, 74-83% of water, crush and sti...
