Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glaze for a salt tile containing metal silicon and a method for manufacturing a salt tile using the glaze,

The present invention relates to a glaze for a salt tile containing metal silicon which can increase the solar absorption and thermal conductivity by coating the surface of the tile with a glaze containing metal silicon in order to produce the glaze from the seawater, The present invention relates to a method for manufacturing a salt tile using the same.

Sea salt production facility refers to sea water of salinity of 23 degrees with the salinity of 27 (sea of salt) by the heat of the sun, wind power by the wind, It refers to a facility to evaporate and concentrate to a degree.

There are various rusts, debris, grit, pests and other pollutants from the infrastructure for compaction in the ground, pollutants from coastal tidal flats and tidal flats, and contaminated seawater. In order to prevent these substances from being mixed with seawater or salt obtained for the purpose of saltification, it is used as a floor covering material such as a plate made of a synthetic resin material or a tile such as a porcelain to cover the ground of the determined paper.

In order to concentrate sea water and produce sea salt, the temperature of sea water has to be raised to high temperature. In order to improve the heat absorption from the sun, the coloring material added as a flooring material is added. When the flooring material is scratched by using a rubberized material, the flooring material is flawed and the generated flaws cause the harmful substances to be dissolved PVC, and flooring materials containing coloring materials are shaved and mixed in the salt of the sun. In addition, since the structure formed on the side of the salt front is fixed by using a nail or a screw in order to fix the base, there is a big problem that it is contained in the salt produced by the oxidation of the nail or the screw during long use.

PVC, one of synthetic resin materials widely used as a flooring material in a tidal flat, is a plastic material widely used in daily life because of its low price and excellent chemical resistance. They add a large amount of plasticizer, such as phthalate compound, to improve elasticity and adhesion, but most of them contain endocrine disrupting substances, making them susceptible to carcinogenesis, namely, by the International Agency for Research on Cancer (IARC) 2B group. In Korea, it is prohibited to use according to the standards of Food Sanitation Act and container packaging.

Metallic silicon is a material with 99% or more of silicon produced by the redox reduction method from raw materials such as silica and carbon reducing agent. It is the lower quality of polysilicon which is the most basic material of the photovoltaic material. The thermal conductivity (K) was 170.0 w / m ° C, and copper (397w / m ° C), gold (315w / m ° C), aluminum (238w / m ° C), magnesium (155w / m ° C) ) With very high values. Higher thermal conductivity increases heat flow and, conversely, lower thermal conductivity is used as an insulation material to interfere with heat flow.

When Al 2 O 3 is a representative of oxide ceramics, SiC is a non-oxide ceramics Is widely used as a representative. SiC fibers have been actively used as reinforcing materials for ceramic and metal composite materials, and boron fibers are mainly used as high-performance epoxy reinforcing materials.

Especially, SiC with excellent physical properties will be used as a reinforcing material if it is solved only by a price problem which is much higher than other reinforcing materials.

(Experiment result)

1. Changes in sea water temperature with the salt tile of Example 5 and the salt tile of Comparative Example.

As shown in Table 1, the seawater temperature of the container containing the salt tile prepared in Example 5 started to rise after 10 minutes at the initial temperature of 11 占 폚.

In the tile of Example 5, the heat absorbed from the lamp by the tile itself was 41.5 ° C and 39.4 ° C after 4 hours, respectively, as compared with the tile tile of Comparative Example. This was not very large, although there was a slight difference in the ability of the tile itself to absorb heat from the lamp. However, the temperature of seawater at the same time shows a significant difference between the two experimental conditions.

Under the condition that the salt tile of Example 5 was installed, the temperature of seawater was 38.3 ° C,

The temperature of the seawater at the condition that the salt tile of the comparative example is installed is 32.8 ° C, and it can be seen that the temperature difference of the seawater at the two conditions is very different.

This can be interpreted as the effect of the thermal conductivity of the salt tile (using the metal silicon glaze) of Example 5. In other words. The absorption heat absorbed by the tile salt tile of Example 5 having a very high thermal conductivity was easily conducted to the sea water to increase the temperature of the sea water while the temperature of the sea water at the place where the tile salt tile of the comparative example was installed was lower than that of the comparative example tile tile It can be concluded that the salt tile of Example 5 was not increased by the temperature of the seawater.

Therefore, it can be seen that the salt tile of Example 5 can be a very effective means for raising the temperature of the crystal paper in comparison with the salt tile of the comparative example.

2. Characteristics of salt germination

There is also a large difference at the starting point of salt production in each condition in which the salt tile of Example 5 and the salt tile of Comparative Example are installed. The salt which started to germinate on the surface of the tile at the place where the salt tile of Example 5 was installed was visually different from the amount of salt which starts to germinate on the surface of the salt tile of the comparative example. These results ultimately contributed greatly to the difference in salt production produced in both conditions. (See Fig. 3)

3. Salt production

As shown in Table 2, after 72 hours, the amount of salt produced under the condition that the salt tile of Example 5 was installed was 23.68g on average, and the average amount of salt produced under the condition that the salt tile of Comparative Example was installed was 18.22g, It is confirmed that the amount of salt produced in the condition that the salt tile of 5 is installed is increased by 5.46 g and the salt production is increased by about 30%.
