The porous feldspar component may be a mixture of the first feldspar powder (Pb1) and the second feldspar powder (Pb2).

In the present invention, the first feldspar powder (Pb1) means a feldspar component having a relatively small particle size, and the second feldspar powder (Pb2) means a feldspar component having a relatively large particle size.

Here, the particle size is defined by the size of a sieve (Czech) used for sorting particles. The particle size may be an average particle size of the particles. Here, the particle diameter means the effective diameter of the particle that separates the particles.

Standard Mortar Layer and Test Concentration After 30 days of curing of the charged mortar layer using the porous feldspar, the mortar layer was dried for 5 days with hot water at 50 ° C for 24 hours to remove water remaining in the mortar layer. Thereafter, a heat conduction experiment was performed.

The boiler for the hot water supply was installed with the 3 kW electric boiler at the reference copper and the test copper respectively. In order to understand the amount of electric power generated by the operation of the boiler, a single-phase, two-wire integrated power meter was connected to the boiler. Also, in order to understand the temperature change due to the operation of the boiler, the mortar layer of each of the reference copper and the test copper was punctured at intervals of 80 cm and a thermometer was installed, and the temperature was remotely measured in real time.

5A shows the result of the temperature change in the heating process in which hot water at 50 DEG C was supplied into the hot water pipe at the heating floor for 5 hours.

On the other hand, the reference mortar layer (control model) shows a temperature increase rate similar to that of the test copper up to 20 ° C, but shows an average temperature rise rate lower than that of the test copper during the entire time period of the heating process.

Referring to Fig. 6, the power consumption of the boiler during the heating time of 3 hours is the same in the reference copper and the test copper. However, in order to reach the target temperature of 30 캜, the test copper boiler is operated for 120 minutes while the reference copper boiler is operated for 260 minutes (see A in Fig. 6). At this time, the power consumed until reaching the target temperature of 30 ° C was about 4.4 to 4.6 times larger than that of the test copper.

Referring to FIG. 6, in the heating process, the maximum temperature of the reference copper mordant layer (Control model) is 31.6 ° C and the highest temperature of the charged mortar layer (test model) using the porous copper feldspar for test is 36.8 ° C.

Referring to FIG. 7, after 100 minutes from the cooling process, the thermal image of the hot water piping of the reference model mortar layer (control model) becomes very faint. On the other hand, the thermal image of the hot water piping of the charged mortar layer (test model) using the porous fused silica of the test copper is clearly observed even at 100 minutes from the cooling heat treatment.

Referring to FIG. 8, the temperature of the reference copper and the test copper mortar layer in the second embodiment was measured every 30 seconds at a position 10 cm away from the hot water pipe. At 60 minutes of heating, the temperature of the charged mortar layer (test model) using the porous fused silica reaches 24.5 ° C and the temperature of the reference copper mortar layer reaches 19.7 ° C.

In the second experimental example, the cooling process progressed from a total of 75 minutes to a total of 200 minutes. At a total of 200 minutes, the temperature of the charged mortar layer (test model) using the porous fused silica decreased to 14.6 ° C, The temperature of the mortar layer (control model) is observed to be reduced to 12.3 ° C. Thereafter, the reference copper boiler is operated and heated until the temperature of the reference copper mortar layer reaches 14.6 ° C, and the additional power is required (refer to 2 and 4 in FIG. 8).
