Embodiment 1

[0099] Embodiment 1: Manufacture spherical shaped body

[0100] Using the device from the hopper 1 to the classifier 7, the thinned wood of cedar is used to prepare a vegetable fiber material powder with a particle size of 60-200 mesh and a moisture content of 8% by weight. Evenly mix 58 parts by weight of the vegetable fiber material powder and 17 parts by weight of the vegetable binder powder to prepare a mixed powder, add 25 parts by weight of water to the mixed powder evenly for humidification, and use a mixer 8 A molded body raw material was obtained. As the vegetable binder powder, a mixture of 97% by weight of cornstarch, 2% by weight of xanthan gum, and 1% by weight of tamarind gum was used.

[0101] After putting the above-mentioned molded body raw materials into the injection cylinder from the raw material hopper of the injection molding machine, the molded body raw materials were extruded into a mold according to a conventional method to make a spherical molded bod...

Embodiment 2

[0103] Example 2: Making a Soup Bowl

[0104] Using the device from the hopper 1 to the classifier 7, bamboo is used to prepare a vegetable fiber material powder with a particle size of 60-200 mesh and a moisture content of 5% by weight. 63 parts by weight of the powder and 20 parts by weight of the vegetable binder powder were uniformly mixed to prepare a mixed powder, and 17 parts by weight of water was uniformly added to the mixed powder for humidification, and a raw material for a molded body was obtained by a mixer 8 . As the vegetable binder powder, a mixture of 98% by weight of cornstarch and 2% by weight of xanthan gum was used.

[0105] After the above-mentioned molded body raw materials were dropped into the injection cylinder from the raw material hopper of the injection molding machine, the molded body raw materials were extruded into the mold according to a conventional method to make a soup bowl with a weight of 65 g. The injection pressure during molding was 83...

Embodiment 3

[0107] Example 3: Manufacture of pendant pendant (Pendanttoptop)

[0108] Using the device from the hopper 1 to the classifier 7, grass is used to prepare a vegetable fiber material powder with a particle size of 60-200 mesh and a moisture content of 7% by weight. Uniformly mix 73 parts by weight of the vegetable fiber material powder with 14 parts by weight of the vegetable binder powder to prepare a mixed powder, and uniformly add 13 parts by weight of water to the mixed powder for humidification, and use a mixer 8 to obtain a molding body raw materials. As the vegetable binder powder, a mixture of 98% by weight of potato starch, 1% by weight of xanthan gum, and 1% by weight of tamarind gum was used.

[0109] After putting the above-mentioned molding raw materials into the injection cylinder from the raw material hopper of the injection molding machine, extrude the molding raw materials into a star-shaped mold with 5 cavities according to the conventional method to make pen...

Abstract

The invention relates to the vegetal fibre molding material and the molding method. The vegetal fibre powder is mixed with the vegetal binding agent powder which is formed by mixing the starch powder and the pectin powder. Then the mixture is mixed with water and then the vegetal fibre molding material is generated.

Description

technical field [0001] The present invention relates to a method for manufacturing a biodegradable fiber material molding, in particular to a biodegradable fiber material characterized by mixing plant fiber material powder and plant binder powder, adding water therein, and molding Manufacturing method of molded body. Background technique [0002] So far, plastics made from chemically synthesized products have many advantages, such as being free to form, strong, and mass-produced. However, when it is discarded, it will not be biodegradable in soil, and at the same time, when it is burned, it will cause social problems such as harmful substances such as dioxin. Recently, technologies that require industrial waste to have little impact on the natural environment, such as waste in the soil, can be naturally decomposed by the action of bacteria, or technologies that do not produce harmful substances such as dioxins when burned. As such a technique, a technique for producing a b...
