陽光令二價鐵催化劑分解甲醛更快

數據記錄顯示自然紫外線促進二價鐵催化劑對甲醛的氧化分解

現在市面上新屋除甲醛服務用的觸媒,一般在工程完成那天,量度出來的效果都會很好。其實甲醛是溶於水的化合物,基本上你噴水喉水也會有效果。 觸媒藥劑的好壞比較,決戰位在其長期功效。這也是可以量度出來的,只要有合適的工具就可以,我就用我公司辦公室示範了這個做法:

  1. 就看上星期公司內的甲醛濃度記錄,每天七點鐘,太陽射入室內,甲醛濃度就開始懸崖式下跌,我們九點鐘才有人開冷氣的啊。
  2. 22-23 日沒怎麼跌,那兩天是周末,沒有人上班開冷氣,也打風下雨,那些潛在不同家俱內的甲醛,看着室內溫度高,觸媒沒太陽給他能量,都跑出來玩了。

現在市場上所有光觸媒都會自稱在可見光內有功效,無需紫外光照射。其實大部份的品牌,根據我看過的實驗室報告,在可見光之下的功效,都接近零。但只要不是零,說有功效就沒有騙你 。

UV on Ferrous Catalyst Decomposes Formaldehyde Faster

Data logs show natural sunlight promoted ferrous catalytic oxidation on formaldehyde

Charts Prove

Simple IAQ data logging can show effectiveness of those ferrite catalyst coating we sprayed all over our office. It also proves that UV light remains the best energy source to active metallic oxide molecules decomposing airborne chemical contaminants.

Sunlight Gives UV

Data charts we logged shows a sharp decline of formaldehyde (HCHO) level in office around 7am, two hours before our normal office opening hours aka air conditioning starting time. Thanks to our array of East facing windows. Even with vertical blinds installed the UV light just comes straight through empowering photocatalyst coating previously sprayed on windows and blinds.

Rainy Days

The drops on July 22-23 were less sexy simply because Hong Kong was in heavy rainy days over the weekend.
