According to the present invention configured as described above, a sawdust obtained from wood, such as pine or poplar, which is harmless to humans or livestock, or mixed with pulverized powder and white clay crushed wood pulp of the pine or poplar, and mixed with the mixture to the human body A combination of harmless konjac or agar or starch and gluten is added to form an adhesive produced by gelatinization, and a mixture of powder, white clay and adhesive crushed by sawdust or wood pulp of the combined wood is formed into a predetermined shape. By pouring into a mold and solidifying and drying, a disposable product having a desired shape that is harmless to humans or livestock and does not cause environmental pollution is completed.

Hereinafter, the present invention configured as described above will be described in detail.

That is, the main raw material of the present invention is a sawdust of wood finely crushed pine or poplar trees, such as a strong odor and powder pulverized finely wood pulp of the pine or poplar trees, edible and harmless to humans and livestock Available clay is used.

Here, the powder obtained by crushing the wood sawdust or wood pulp finely is about 170 hours in the fresh water at room temperature to remove the gin or pigments remaining in the wood, and then the sawdust or wood pulp of the wood The boiled fresh water is boiled for about 5-6 hours and dried by purification to finally remove impurities.

At this time, potassium sulfite or sulfur dioxide composed of ingredients that are harmless to humans and livestock during the process of crushing such wood sawdust or wood pulp in fresh water or boiling fresh water in which the wood sawdust or wood pulp is immersed. It is also possible to add bleach such as these.

Then, the ground powder refined and dried by sawdust or wood pulp is mixed with white clay used as a main raw material, and the mixing ratio of powder and white clay of sawdust or wood pulp is 2: 1, respectively. It is mixed in the ratio of. However, the mixing ratio of the dust of the sawdust or wood pulp and clay is 2; The mixing ratio is not limited to 1, but the mixing ratio can be changed slightly depending on the use of the disposable product.

Here, it is necessary to adhere to each other by adding an adhesive to the powder and white clay pulverized the sawdust or wood pulp of the mixed wood, the adhesive is a konjac (ie, to make the underground stem of the old herbs It is a kind of food made by mixing lime oil, agar or a mixture of 20% Gluten with 80% starch. Boiling at a temperature of 90 ℃ repeat the stirring operation to form a gelatinous (糊化) state.

Here, in the gelatinization process of the adhesive, it is necessary to evenly stir with a stick or the like to ensure that the heating temperature is transmitted as a whole.
