Formwork apparatus for solidified sulfur product

Abstract

The invention provides a formwork apparatus for a solidified sulfur product. The cavity of a formwork body (1) wherein the inside of an outer shell (6) provided with a sealable cavity is heated to a designed temperature range higher than the melting point of sulfur is fully packed with a sulfur-containing material. As the sulfur-containing material becomes cold and thus shrinks within the cavity as described above, a lid is put on the top opening (11). Thus, the inside becomes sealable and a definite pressure is applied thereto. At the same time, replenish sulfur-containing material containedin a replenish tank (2), the inside of which has been heated to the designed temperature range as described above, is supplied into the cavity due to the pressure applied to the above-described replenish tank (2).

Description

technical field [0001] The present invention relates to a mold device for solidified sulfur products, which fills sulfur-containing materials in a molten state into the cavity of the mold body and cools and solidifies them, thereby forming solidified sulfur products. Specifically, the present invention relates to a solidified sulfur product. A mold device for a sulfur cured product that replenishes the sulfur-containing material in a pressurized replenishment tank into the cavity as the sulfur-containing material filled in the cavity cools and shrinks. Background technique [0002] Generally speaking, concrete mixed with aggregate and cement is used as a material for civil engineering or construction. On the contrary, in recent years, focusing on the properties of sulfur, which is solid at room temperature and melts when heated to about 119~159°C, some people have tried to mix specified samples with this sulfur and use it as a kind of sulfur for civil engineering or construc...

AI Technical Summary

Problems solved by technology

Conventionally, when a sulfur-containing material in a molten state is solidified, the part in contact with the mold is cooled rapidly when it flows into the mold, so there are problems such as cracks on the surface of the sulfur solidified body after the mold is removed.

[0012] In addition, since the molten sulfur-containing material filled into the mold shrinks during cooling and solidification, even if it is fully filled to the upper surface of the mold, the sulfur-containing material sinks and creates voids in the upper part of the product. , there are cases where the required style as a product cannot be met

In this case, although there is a method of applying a sulfur-containing material to the product that is divided into two and taken out from the mold to repair it, it takes too much work, and the appearance is poor and the value of the product is low.

Moreover, when the gap is large, there is also a situation that cannot be repaired

[0013] In addition, if the sulfur-containing material is injected into the mold without a cap on the filling port of the above-mentioned mold, and when the upper surface of the sulfur-containing material filled in the mold sinks to form a void, the sulfur-containing material will be replenished. The surface of the sulfur-containing material begins to solidify to form a hardened layer, which weakens the strength of the product

In this case, there are cases where the required performance as a product cannot be satisfied
