Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] A method for making a bamboo fiber molded product, comprising the following steps: fine grinding: the bamboo bamboo fiber directly enters a hot grinder for mechanical grinding, so that the fiber breaks and destroys the hydrogen bond inside the cellulose; dissolving: the ground The final bamboo fiber is dissolved in an organic solvent for hydraulic stirring to form a fiber slurry, so that the bamboo fiber can be fully stretched; vacuum adsorption: the fiber slurry is absorbed by a vacuum pump, and the absorbed bamboo fiber is adsorbed on the mesh mold; Shaping: Put the net mold into the shaping machine, and shape it by high temperature and high pressure.

[0014] In order to ensure its stability, the bamboo fiber can be fully finely ground. In step a, the thermal grinding temperature of the bamboo fiber at the thermal grinder is 110-125 degrees, and its...

Abstract

The invention discloses a manufacturing method of a bamboo fiber molding type product. The manufacturing method comprises the steps of: machining bamboo fibers through a machining process of accurate grinding, dissolving, vacuum-absorbing and shaping; enabling the fibers to take on brooming to the maximum extent by accurately grinding and hydraulically stirring the bamboo fibers for 30-50 min based on characteristics that the fibers of the bamboo fibers are long and thick, but not soft enough; and then enabling a surface of a finished product to be smooth and beautiful like a ceramic through vacuum absorption of moisture and high-temperature instant shaping. The manufacturing method of the bamboo fiber molding type product realizes 60-70% high-purity machining of the bamboo fibers, not only can realize green production of the bamboo fiber products, but also can be satisfied with requirements on production of environment-friendly tableware and packaging containers as the bamboo fibers obtained through the manufacturing method can be satisfied with the requirements on the bamboo fibers needed for the environment-friendly tableware.

Description

technical field [0001] The invention relates to a manufacturing method of bamboo fiber for molded products, and particularly relates to a method for manufacturing molded products of bamboo fiber materials used in the production of environmentally friendly tableware and packaging containers. Background technique [0002] Today's environmentally friendly tableware and packaging containers are made of alloys, ceramics and ordinary paper. However, such materials make the products expensive to manufacture, which is not conducive to environmental protection and is prone to bacterial contamination and other adverse phenomena; [0003] Existing bamboo fibers have the characteristics of good air permeability, instant water absorption, strong wear resistance and good dyeability, and at the same time have natural antibacterial, antibacterial, mite removal, deodorant and anti-ultraviolet functions. And the bamboo fiber on the market has following two classes: the one, the regenerated fi...
