Process for preparing original ecological plant fiber molded product from plant straws

Abstract

The invention discloses a process for preparing an original ecological plant fiber molded product from plant straws, and the process comprises the following steps: (1) spraying a bio-enzyme preparation and a softening agent to the plant straws, mixing evenly, naturally stacking to obtain mature pulp, controlling mature pulp pH to 7 + / -1 by adjustment of dosage of the bio-enzyme preparation and the softening agent, meanwhile controlling the mature pulp to remove only 5% of lignin and retain 95% of the lignin; (2) washing and screening the mature pulp, and directly beating the pulp to obtain finished pulp; and (3) using a pulp suction net mould for molding the finished pulp, then demoulding, drying, and finally thermally forming, stamping trimming and sterilizing. The process has the advantages that the production process is not only simple in route, short in production cycle, low in energy consumption, low in cost and free of requirement for production sites, the produced original ecological plant fiber molded product is good in toughness, strong, not easy to break, and the shape of the plant straws is clearly visible.

Description

technical field [0001] The invention relates to a process for making molded products, in particular to a process for making original ecological plant fiber molded products by using plant straws. Background technique [0002] With the development of industry, a large amount of fluorine-containing substances have risen into the atmosphere, causing extensive damage to the ozone layer on which human beings depend. Thousands of kilometers of ozone holes have been formed in the Antarctic and the Arctic, causing extreme damage to the ecological environment of the earth. great harm. To this end, the United Nations Environmental Protection Agency held a world-wide environmental protection conference. In 1998, it passed the "Vienna Convention" for the protection of the ozone layer and the "Montreal Protocol" on substances that deplete the ozone layer. of fluorine-containing substances. [0003] In recent years, many disadvantages of plastic products (especially expanded polystyrene ...

AI Technical Summary

Problems solved by technology

[0006] 1. Pulp molding: It is molded from pulp, and pulp needs to be produced first. The production process will not only discharge waste liquid and bring black pollution, but also have high production costs and lack of market competitiveness.

[0007] 2. Materials using whole starch as raw material: the production process is pollution-free, and the product is beautiful and hygienic. It is an ideal environmental protection catering utensils, but the price of raw materials is high and the investment in equipment is large, so it is difficult to have a market prospect.

[0008] 3. Decomposable plastic products: After being discarded, they can be decomposed into fragments, but they cannot continue to be degraded into harmless substances. The accumulation of fragments in the soil can still cause land compaction and affect the growth of crops

Disadvantages: Coating and drying equipment has large capital investment, high cost, complex process, long production cycle, high energy consumption, and requires a large production site

[0013] 3. Add a large amount (accounting for 25% of the total weight) of high-priced waterproof glue to the raw materials, and use wet high-temperature and medium-pressure molding to produce 4 fast food boxes of 60 grams at a time. However, during the pressing process, due to moisture in the raw materials Many, need to deflate multiple times, the aging time is more than 1 minute each time, need to be dried after forming, high energy consumption, and poor waterproof
