As shown in Table 1 above, the composition of the No. 1 mixture contains only powdered cleansing. This is a conventional powder cleaning composition. Compositions 2 to 6 are related to the powder-blended base according to the present invention. The content ratio of the powdered cleansing paper was fixed at 55% by weight based on the total weight of the composition, and experiments were conducted while controlling the mixing ratio of the white porcelain and acid cleansing paper.

Experiment of measuring your bending strength

Table 2 below summarizes the experimental results of measuring the bending strength by making six test pieces for each composition using the compositions 1 to 6 above. Here, the experimental conditions were conducted within a range in which the substrate can maintain plasticity. The range of maintaining plasticity may mean that the test piece is hardened after the test piece is manufactured using the base material, and before it becomes a state in which its shape cannot be changed even when an external force is applied. The firing temperature was performed at 1250 ° C, and each test piece was prepared by preliminary roasting. However, if necessary, it is possible to proceed from primitive roasting to chaebol roasting.

As described in Tables 2 to 7 above, 6 specimens using each composition from No. 1 to No. 6 were manufactured to have width, thickness, length, and load within a predetermined range, respectively, to measure the bending strength and to measure the bending strength. A correction value considering the average value and standard deviation of was derived.

As described in Tables 2 to 7 above, the correction value of the bending strength of the six types of compositions can be grasped from the composition No. 4 in Table 5, the value of which is significantly increased to 519 kg / cm ² . That is, in the case of the 4th to 6th composition, it can be seen that the bending strength is significantly increased compared to the conventional one. Therefore, based on the total weight of the composition, it can be seen that 55% by weight of the powder-cleaned paper, 25 to 35% by weight of the white porcelain, and 10% to 20% by weight of the acid-cleaned paper show significant characteristics in the bending strength.

In addition, the test piece having the highest bending strength was made of the composition No. 6. As shown in Table 7 above, the average value and the correction value of the bending strength of the composition No. 6 were derived the highest. The composition No. 6 is characterized in that 55% by weight of cleansing paper, 35% by weight of white porcelain and 10% by weight of acid cleaning paper based on the total weight of the composition. In other words, the weight ratio of each component included in the composition, such as powder-cleaned paper, white porcelain, and acid-cleaned paper is 11: 7: 2.

Six test pieces produced using the composition No. 6 can be manufactured to fall within a range of 4.96 to 5.47 mm in width, 50 mm in length, and 4.54 to 4.87 mm in height. The bending strength of the six test pieces produced based on the composition No. 6 is 438 to 630 kg / cm ² Can be In addition, the average value of the bending strength of these six test pieces is 510 kg / cm ² , and the correction value considering the standard deviation is derived as 536 kg / cm ² .

Compare your color

Referring to Figure 1, Figure 1 is a photograph of a test piece made using the six types of compositions in Table 1 above. However, only two test pieces (for example, 1-1, 1-2) with the highest number per each composition were arranged to take pictures. Referring to the drawings, it can be seen that each test piece was split in half, which was split in the course of the experiment for measuring the bending strength.

If you compare the color of the composition from 1 to 6, in the case of No. 1, it can be seen that it is a test piece that contains only powdered cleansing, which is close to brown and contains a yellow color. However, as the content ratio of white porcelain becomes higher and the content ratio of acid cleansing becomes lower, it can be seen that brown and yellow colors gradually disappear and become light gray or blue gray. In the case of 6, it is expressed in a light grayish-blue color when compared to other compositions 1 to 5. That is, it can be understood that the color of the test piece of the composition 6 is a gray-blue color that expresses a luxurious natural beauty that goes well with the work.
