나) 비교시험B) Comparative test
원적외선 방사 세라믹분말 중 하나로서 시판하고 있는 상품명 라디에코 20g에 상기 가)용액 0.1ml를 혼합한 혼합액 A를 만들고 상기 라디에코 30g에 상기 가)용액 0.1ml를 혼합한 혼합액 B를 제조하여, 상기 혼합물 A,B각각을 부직포 1m2당 스크린 도포하였다.One of the far-infrared radiant ceramic powders was prepared, a mixed solution A obtained by mixing 0.1 ml of the a) solution in 20 g of a commercially available radico powder was prepared, and a mixed solution B of 0.1 ml of the a) solution was prepared in 30 g of the radio. Each of A and B was screen-coated per 1 m 2 of nonwoven fabric.
상기 용액이 도포된 부직포를 악취가 심한 화장실에 방치하여 정화도를 시험한 결과 혼합액 A를 도포한 부직포의 경우는 약 60분만에 완전 탈취정화가 되었고 혼합액 B를 도포한 부직포의 경우에는 약 40분만에 완전 정화되었다. 이상의 시험결과로 보아 탈취효과등은 원적외선 세라믹의 비율이 높을수록 더 효과가 크다는 것을 알았다.The solution-coated nonwoven fabric was placed in a odor-rich toilet and tested for purification. The nonwoven fabric coated with the mixed solution A was completely deodorized in about 60 minutes, and only 40 minutes for the nonwoven fabric coated with the mixed solution B. Cleansed completely. The above test results show that the deodorizing effect is more effective as the ratio of far infrared ceramic is higher.
