Problems solved by technology

However, it will be more difficult to crush the stems, stems, roots, etc. of plants into fine powders of about 60 meshes, and the cleaning and storage of these raw materials will also be a problem.
On the other hand, this product also needs to be sprayed on the surface, so the negative effect of the tape still exists
[0013] In addition, the results of specific tests and tests of products are rarely disclosed in the above prior art, so it is difficult to obtain the actual practical effect of the prior art

Embodiment Construction

[0028] The following are embodiments of the present invention and relevant detection data:

[0029] Raw material composition ratio is:

[0030] Corn flour 70.0-75.0%, starch 5.0-7.0%, wheat flour 4.5-6.5%,

[0031] Food-grade resin 8.0-12.0%, lithopone 3.0-5.0%.

[0032] After the above raw materials are well proportioned, stir them to make them uniform, and the raw materials at this time are still in powder form. Then put the material into the mold cavity, pressurize, and vent the mold at the same time. The temperature of the initial pressure is 150-200°C, and the pressure is 200-250 tons / 50×50cm 2 , Keep the pressure for about 1 minute and then release the mold. At this time, the product is slightly soft, and it can harden naturally after being left for a while. After the product is naturally hardened, it can be finished by edge grinding and disinfection, and it can be packaged for use.

[0033] The test situation of the product (the food-grade resin used in the followin...

Abstract

A process for preparing the disposable dining utensil (or tool) includes such steps as mixing wheat flour, starch and food-class resin, and die pressing at 150-200 deg.C.

Description

technical field [0001] The present invention relates to a method of manufacturing disposable tableware, and tableware manufactured by this method. In the present invention, food-grade resin is added into starch and the like, and after mixing, molding is carried out at 150-200°C to form disposable tableware. Background technique [0002] Due to environmental reasons, it has been inclined to no longer use disposable tableware made of foamed polymer materials, but to use degradable materials. In order to solve the problem that polymer materials are difficult to degrade, a solution was proposed to add a certain amount of starch to the foamed polymer chains to promote the degradation of materials in the future. However, it still takes a long time for the degradation of the network polymer residue formed after starch degradation of this kind of material, so its effect is not ideal. There is also a technical scheme of using paper disposable tableware, but in order to make this pa...
