Description of the invention--This creation is a method for manufacturing a container that can be naturally decomposed. In short, the invention uses natural fiber to add colloid and foaming agent to mix, and finally uses a mold to form a container manufacturing method. Can be naturally decomposed into fertilizer, lightweight, heat-resistant, waterproof, non-toxic container products. At present, the widely used Polyurethane container utensils on the market. The raw materials of Polyuron are polystyrene (Ps) foamed into distyrene. It is a plastic raw material extracted from petroleum. It is composed of stone hate and hydrogen. Polyurethane appliances are made of polystyrene and a foaming agent, and then heated to form I. Depending on the expansion ratio, they can be made into disposable tableware and raw materials; noodle bowls, burger boxes, and other containers. ; Although the above-mentioned conventional Polyuron appliances have the advantage of waterproofing, 'but' due to the age of Polyuron tableware is buried; Zhao I ^, and it will be born after it flows into a landfill or incinerator! , I will not decompose in 1 year ', it will affect the normal of the plant on the soil surface, though, although the Polyuron tableware is a kind of plastic which is difficult to decompose, it is the culprit of life-saving; The "improvement" ticket, and the two above-mentioned people developed the solution that this case expects. Ϊ́The main purpose of this helmet is to provide a kind of manufacturing technology for finished products that are resistant to water, water, and decomposable containers, and are manufactured by the ownership system (...,% guarantee formula), which is', ·, σ Material properties, can be self-decomposed into materials in a short time ',' ,,: water, non-toxic colloid and foaming agent mixed and foamed to produce unique, and the present invention also uses various manufacturing methods' its finished product 572817 five, Description of the invention (2) Light weight and meet the requirements of food containers. The present invention is a secondary-objective, which is to provide a naturally decomposable manufacturing method of the innocuous material of the present invention (the non-toxic environmentally friendly formula glue η: after the agent is mixed and foamed), and after being buried for a period of time, it is more easily hydrolyzed. And others please refer to the following: rice straw, high-grade, "material" package, which is placed in the material (approximately four 5% of the implementation of this book ~ the purpose, the details of the manufacturing steps used and the map The system shown below takes a variety of lengths, coconut husks, and wheat husks to use natural agricultural beer residues; moreover, it can be used to detect substances in the feeding step, such as potato flour, soybean flour, and so on. Between the meshes). 〇), after crushing the stearates of the family, the proportion is 5% ~ 30%, the technology and means are described later; the first production process is shown, the stem plants, including, wheat stems, cotton waste Materials, such as temple powder materials. Selected materials Divide. After the steps are completed, the material required by the mesh ruler is formed into the material, PVA glue, and the raw material 3 is crushed and fully related to the creation of this case. In order to achieve the effect, the production steps shown in the figure shown in the figure of the present invention are listed. Including, reclaiming steps (10) straw, straw hulls, forage beams, pods, etc .; also can be stalks, slag, bagasse, including: corn flour, stirrup, detection steps (20), Does it contain heavy metals and other toxic, crushing and screening steps (3 in the crusher, and through the gel blending step from 10 mesh to 400 (4 amount of additives: such as fat, Pv A gum is 70% for example, Another eight glue 6 572817
