| Popis: | 96 Study of the porosity ceramics is basically made up of Al2O3 and SiO2. Nano -covered material contains nano TiO2, SiO2 and Al2O3 particles. By using a different test prescription to figure out the best spreading condition, nano material could be covered on the board of ceramics through directly attached and naturally dried to achieve the function of the antiseptic and algae-removing. Experimental result revealed that thickness of nano-covered material is approximately 100nm. After 1000 times washing and brushing of sponge, thickness of nano-covered material is still nearly 80-90nm. On the antiseptic test aspect, when we took 18 hours to cultivate colon bacillus, the porosity ceramics covered with nano particle material can decrease fungus from 4.93´109 (cfu/mL) to 1.94´105(cfu/mL), completely attaining 99.99% rate of antiseptic. The porosity ceramics covered with nano particle material put into a fish tank, which is full of green algae. Sixty hours later, it could effectively eliminate algae growth in the fish tank and turn into clearness of water quality. With such a technique, porosity ceramics could be done with various accessories; consequently, it could be implemented for aquatic industries; additionally, it is appropriate to view and admire algae-removing fish tank. |
