How to reduce the pollution of formaldehyde?

甲醛最重要的是预防，而不是治理。

Formaldehyde is the most important thing to prevent, not to govern.

也就是说装修过程中，要尽量少用存在甲醛释放隐患的建材。比如各种胶水、人造板材、复合地板、板式家具、腻子、油漆、乳胶漆等一定要选环保指标更好的产品。

That is to say, during decoration, we should minimize the use of building materials which have hidden dangers of formaldehyde. For example, all kinds of glue, man-made board, composite floor, plate furniture, putty, paint, latex paint and so on, we must select environmental indicators and better products.

甲醛哪里来的？为什么说会释放长达10年？甲醛的来源是酚醛树脂或脲醛树脂，也就是我们板式家具或板材里用的胶水。会在常温状态下慢慢分解出游离的甲醛。

Where is the formaldehyde coming from? Why is it going to be released for up to 10 years? The source of formaldehyde is phenolic resin or urea formaldehyde resin, that is, the glue used in our panel furniture or board. It will slowly decompose the formaldehyde when traveling at normal temperature.

民间偏方除甲醛：你可能听说过以下这些除甲醛的办法，水、醋、红茶、茶叶梗、柚子皮、菠萝等等，这些方法，基本有效性接近于0，别费力了。

Folk side side removal of formaldehyde: you may have heard of the following methods of removing formaldehyde, water, vinegar, black tea, tea stalk, pomelo skin, pineapple, etc. these methods, the basic effectiveness is close to 0, do not bother.

竹炭、活性炭、硅藻泥吸附甲醛：能不能吸附？能，但是有2个条件，一个需要空气流动让甲醛和这些吸附载体接触；第二是接触面积要大。但吸附存在的问题就是饱和之后又会释放出来。也就是说你买足够量的活性炭，每天换新的，理论上或许有点用。

Bamboo charcoal, activated carbon and diatomaceous mud adsorb formaldehyde: can they adsorb? Yes, but there are 2 conditions. One needs air flow to make formaldehyde contact with these adsorption carriers. The second is the large area of contact. But the problem of adsorption is that it will be released after saturation. That is to say, if you buy enough amount of activated carbon and replace it every day, it may be of some use in theory.

绿植吸收甲醛：有一些绿植对甲醛是有吸收功能，比如吊兰，有研究表明如果100平米，层高3米的居室内，甲醛浓度是0.5毫克/立方米的，1颗吊兰需要工作1年才能吸收游离的甲醛，这是不算板材源源不断释放的量。也就是说你家里养个几十上百颗吊兰理论上或许稍微能有点用。

Green planting absorption formaldehyde: some green planting on formaldehyde absorption function, such as Chlorophytum, such as Chlorophytum, studies have shown that if 100 square meters, 3 meters high in the room, formaldehyde concentration is 0.5 mg / cubic meters, 1 Chlorophytum needs to work for 1 years to absorb free formaldehyde, which is not a continuous release of the plate quantity. That is to say you have in your home a few hundreds of pieces of Chlorophytum theory, perhaps a little bit a bit of use.

光触媒分解甲醛：如果吸附不行，那分解甲醛总可以吧？光触媒（一般以纳米级二氧化钛为代表）可以把甲醛分解成水和二氧化碳。且不说这东西可能有二次污染，也不一定能买到真货，另外光触媒的工作条件是得紫外线照射，也就是说用光触媒治理时屋里得开启紫外灯照明。

Photocatalyst decomposes formaldehyde: if the adsorption is not enough, then the decomposition of formaldehyde is always okay? Photocatalyst (usually represented by nanometer titanium dioxide) can decompose formaldehyde into water and carbon dioxide. And do not say that this thing may have two pollution, and not necessarily can buy real goods, and the working conditions of the photocatalyst is ultraviolet radiation, that is to say, when using a photocatalyst in the house to open the ultraviolet light.

其实最最有用的方法，还是稀释。甲醛浓度低了就安全了，稀释最常用的办法，就是通风。通风其实分很多种，比如开窗、用新风系统、用排气扇等。

In fact, the most useful way is to dilute it. Formaldehyde is low and safe. The most common way to dilute is ventilation. There are many kinds of ventilation, such as windowing, fresh air system, exhaust fan and so on.
