Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a new material composed of konjac powder and non-toxic metal powder that can be used for fishing weights, shotguns and other bullets, and a method for producing the new material.

[0002]

2. Description of the Related Art Recently, as one of the leisure sports, sea fishing, mountain stream fishing, and shooting have become popular. Usually, lead weights are always used for fishing, and clay shooting Bullets made of lead are also widely used. However, lead weights and bullets can cause lead poisoning if left undisturbed in the natural world. Recently, there have been problems with their use by wild bird conservation groups, etc. We are considering a total ban on the use of lead weights and shots.

[0003]

From such a background, the present inventors are abundant in nature, can be obtained at low cost,
Furthermore, focusing on glucomannan, which is the main component of food-grade konjac that returns to harmless substances when left in the natural world, as a result of diligent research on materials containing glucomannan as an alternative to lead weights and bullets, It was discovered that a new material obtained by drying a mixture of konjac powder and non-toxic metal powder can be used for fishing weights and shotgun bullets.

By the way, glucomannan, which is the main component of konjac, is contained in a large amount in konjac potato, which is the underground corm of plants belonging to the family Araceae, and glucose and mannose are combined in a chain at a ratio of 1: 2. A natural polysaccharide having a chemical structure in which an acetyl group and a phosphoric acid are ester-bonded as a side chain, specifically, particles called atypical cells having a long diameter of 0.5 to 1.05 and a short diameter of 0.37 to 0.5 mm. Is forming. The konjac is usually made by adding 20 to 50 times (weight) the amount of water to the konjac flour containing glucomannan as the main component, and leaving it for about 1 to 2 hours at a temperature of about 30 degrees Celsius to sufficiently swell After that, an alkaline solution such as lime milk or sodium carbonate is added to the mixture, mixed and allowed to stand for about 20 to 60 minutes to coagulate glucomannan. The konjac made in this way is widely edible for food, but konjac for food is low in viscosity and hardness because it is made in consideration of texture and chewyness, like lead bullets used for fishing and guns I couldn't make it hard.

The present inventors added a predetermined amount of metal powder having a specific gravity or more to glucomannan (hereinafter referred to as konjac powder), which is the main component of konjac, and produced a weight, a bullet and the like from a material which was further dried. Successful development. The new material according to the present invention dissolves glucomannan when left in the natural world, and the metal powder oxidizes and disintegrates without being poisoned. There is no need to worry about environmental pollution like the weights and bullets.

[0006]

[Means for Solving the Problems] The technical means taken by the present invention to achieve the above-mentioned technical problems are konjac flour and a bullet or fishing consisting of a predetermined amount of non-toxic metal powder with respect to the konjac flour. It is a material that can be used for work weights, etc.
Konjac powder, a predetermined amount of non-toxic metal powder, and a predetermined amount of water are mixed, and this mixed solution is left for at least a predetermined time or more,
Stir the mixed liquid left to stir evenly to solidify the glucomannan, then pour the solidified konjac powder into a predetermined mold and mold it, put the molded product further in a dryer to remove water and shape it. It is a method for producing a material that can be used for bullets, fishing weights and the like, which is characterized by containing konjac powder and non-toxic metal powder.

[0007]

The new material used for the bullet and the fishing weight according to the present invention is basically made as a composition containing konjac flour as a main component. If konjac flour is used as it is, it is not sufficient in hardness and its specific gravity is too light so that it cannot be munged or crushed. Therefore, in the present invention, in order to supplement the above-mentioned properties of konjac flour, tungsten powder is mixed and further dried to increase hardness and weight, thereby making it a new material that can be used for bullets and fishing weights. Bullets and weights molded from this material are polished to improve accuracy, and if necessary, coated on the surface to improve water resistance.

[0008]

[Examples] Details of a new material in which metal powder is mixed with konjac made of konjac powder will be described below. Example 1 1 kg of konjac powder, 0.3-5 kg of tungsten powder and 5-45 kg of water were mixed, and this mixed solution was mixed for a predetermined time or longer, preferably for about 1 hour or longer, more preferably for about 2-hours.
Leave for about 3 hours. At this time, the longer the standing time, the finer the texture of konjac can be made. The tungsten powder added at this time is used to increase the specific gravity of the konjac bullets and weights. The konjac solidified in step (2) is molded with a mold such as a circle, a disc, or a cone. The product molded in step 1 is dried in a dryer to remove moisture and polish to improve accuracy. If necessary, coating treatment is performed.

Since the amount of shrinkage when drying konjac is roughly about 1/5, the amount of tungsten powder and konjac powder is adjusted in consideration of this, and the bullets and weights of the required size and weight are adjusted. To manufacture. Also, the tungsten powder used is JIS H2116, permission number 465034,
Furthermore, as coating materials, algin, carrageenan,
Oils and fats other than minerals (palm oil, animal oil, oils that return to nature, etc.) are desirable. When the finished bullets and weights are left in the natural world, they will decompose in about 3 to 30 days and return to soil and water,
Moreover, since the mixed metal powder is non-toxic, there is no fear of causing pollution.

Next, a method of manufacturing bullets and weights will be described with reference to a flow chart. Prepare a predetermined amount of konjac powder, tungsten powder and water to make a water mixture of konjac powder and tungsten powder. Then, this mixed liquid is left for several hours, and the mixed liquid after standing is kneaded and solidified. The solidified konjac powder is molded and then dried in a dryer. After that, it is polished, and if necessary, coated with a film to make it waterproof. The bullets and weights manufactured as described above are comparable in quality and performance to the currently used lead bullets and weights, and since they are pollution-free, they can replace the current bullets and weights. it can. The present invention can be implemented without departing from the spirit and essential characteristics of the invention.

[0011]

As described in detail above, according to the present invention, since the completed weights and bullets are products containing konjac powder as a main component, the bullets and weights are all natural materials and nontoxic. Since it is made from materials, it will rot and return to soil in about a week if left unattended. Also, the bullets and weights that flow into the river return to water in about 5 to 30 days. Therefore, even if unnecessary weights or bullets are ejected, the treatment is easy, and there is no concern about pollution even if they are left in the natural world after use. In particular,
Even if a bird eats a weight or a bullet, or if the bullet hits the body of a wild bird, there is no fear of lead poisoning as in the past, and it is extremely beneficial from the perspective of environmental protection.
