ている。2. Description of the Related Art A mixture of sulfur and a filler material such as a mineral substance is in a fluid state because a sulfur component is melted in a specific temperature range. When the mixture is cooled, the sulfur is solidified and the filler material is bound by the sulfur. It becomes a strong cured product of the sulfur composition. Compared to those that harden through a hydration reaction such as cement, this sulfur composition can easily obtain a relatively strong cured body even if it contains a large amount of filler material corresponding to the aggregate component of mortar and concrete. In addition, those containing a large amount of filler material hardly shrink during solidification, so they are suitable for the production of large-sized molded members. Furthermore, they exhibit excellent acid resistance and corrosion resistance. Widely used for such purposes.

ましい。The mixing and kneading may be performed by a batch type heating and mixing tank or a continuous type heating and kneading machine. For example, a Henschel mixer, a kneader, a batch mixer or the like can be used. During the mixing and kneading, the inside of the kneading vessel is heated and maintained at 120 to 160 ° C. The kneading time is not particularly limited, but is 3-15.
A minute is enough. Next, when producing a molded product, the kneaded material in a high-temperature state before solidification is filled into a mold or the like to form a desired shape, and this is cooled and solidified (hardened). At the time of molding, it is desirable to fill the kneaded material into the mold heated to about 120 to 160 ° C. because the filling efficiency is increased, and it is more preferable to apply vibration with an output of about 1 to 1000 G at the same time.
Further, pressure molding may be performed. As for cooling, natural cooling is desirable, but a known rapid cooling method can also be performed on a relatively small shaped product. The demolding is desirably performed by cooling to near room temperature.

高密度硬化体を高精度で得ることができる。According to the present invention, in order to obtain a sulfur composition having higher strength, acid resistance and corrosion resistance, it is possible to sufficiently suppress shrinkage during curing even if the sulfur content in the sulfur composition is increased. It is possible to prevent the occurrence of cracks and voids. In addition, the kneaded material having a high sulfur content shows high fluidity at the sulfur melting temperature, so that when performing mold forming or the like, the kneaded material has excellent filling properties and can easily be uniformly and highly filled. Therefore, in combination with the effect of reducing shrinkage, a high-density cured product having a desired shape and size can be obtained with high accuracy.
