Claims (6)
- 하천이나 호소 등에서 조류를 제거함에 있어서, 이산화티탄 박막을 표면에 코팅한 중공 유리구를 수면에 띄우거나 수중에 부유시켜 햇빛에 의한 광화학 반응에 의하여 과다 증식된 조류를 제거하거나 조류의 증식을 억제하는 방법.
- 이산화티탄의 전구체로 티타늄 알콕사이드를 무수 알코올에 희석하고 산 수용액을 적하하여 솔 용액을 제조하는 과정과, 솔 용액에 중공 유리구를 침적하여 천천히 끌어올려 건조시키는 과정과, 건조된 중공 유리구를 소성온도까지 천천히 승온시켜 소성하는 과정으로 이루어지는 것을 특징으로 하는 중공 유리구에 이산화티탄 박막을 코팅하는 방법.
- 제2항에 있어서, 솔 용액 제조과정에서 티타늄 알콕사이드를 티타늄테트라이소프로폭사이드, 티타늄테트라에톡사이드 또는 티타늄테트라부톡사이드에서 선택되는 것을 특징으로 하는 중공 유리구에 이산화티탄 박막을 코팅하는 방법.
- 제2항에 있어서, 솔 용액중에서 중공 유리구를 끄집어 내는 속도를 20㎝/분 이하로 하는 것을 특징으로 하는 중공 유리구에 이산화티탄 박막을 코팅하는 방법.
- 제2항에 있어서, 건조과정이 마이크로웨이브를 조사하는 방법에 의하여 이루어지는 것을 특징으로 하는 중공 유리구에 이산화티탄 박막을 코팅하는 방법.
- 제2항에 있어서, 소성과정이 1∼20℃/분의 속도로 승온하여 300∼600℃의 온도에서 30분 내지 10시간 유지시키는 방법으로 진행되는 것을 특징으로 하는 중공 유리구에 이산화티탄 박막을 코팅하는 방법.
