Formaldehyde is a common problem in the newly decorated house. In order to avoid the harm caused by formaldehyde, ensure the indoor air quality. So we must pay attention to formaldehyde removal in new houses. Today, Ji'nan formaldehyde formaldehyde small series to take you to understand the indoor formaldehyde removal before you need to close the window.
冬天的空气中甲醛对人体的危害最大。我国家庭空气中的甲醛来源主要有以下几个方面：⑴用作室内装饰的胶合板、细木工板、中密度纤维板和刨花板等人造板材。生产人造板使用的胶粘剂以甲醛为主要成分，板材中残留的和未参与反应的甲醛会逐渐向周围环境释放，是形成室内空气中甲醛的主体。⑵用人造板制造的家具。一些厂家为了追求利润，使用不合格的板材，或者在粘接贴面材料时使用劣质胶水，板材与胶水中的甲醛严重超标。⑶含有甲醛成分并有可能向外界散发的其他各类装饰材料，如贴墙布、贴墙纸、化纤地毯、油漆和涂料等。
Formaldehyde is the most harmful to human body in winter. Formaldehyde in the air of our country's home mainly comes from the following aspects: ⑴ plywood, joinery board, MDF, particleboard and other man-made boards used as interior decoration. Formaldehyde is the main component of the adhesive used in the production of wood-based panel. The residual and non reactive formaldehyde in the panel will gradually release to the surrounding environment, which is the main body of formaldehyde in the indoor air. (2) furniture made of wood-based panels. In order to pursue profits, some manufacturers use unqualified plates, or use poor glue when bonding veneer materials. Formaldehyde in plates and glue is seriously over standard. (3) other kinds of decorative materials containing formaldehyde and possibly distributed to the outside, such as wall cloth, wallpaper, chemical fiber carpet, paint and coating, etc.
室内空气中甲醛浓度的大小与以下四个因素有关：室内温度、室内相对湿度、室内材料的装载度（即每立方米室内空间的甲醛散发材料表面积）、室内空气流通量。在高温、高湿、负压和高负载条件下会加剧甲醛散发的力度。通常情况下甲醛的释放期可达3~10年之久。
The formaldehyde concentration in indoor air is related to the following four factors: indoor temperature, indoor relative humidity, loading degree of indoor materials (i.e. surface area of formaldehyde emission materials per cubic meter of indoor space), and indoor air circulation. Under the condition of high temperature, high humidity, negative pressure and high load, formaldehyde emission will be intensified. Generally, the release period of formaldehyde can be as long as 3-10 years.
除甲醛关窗一个礼拜以后再开窗,只有充分的让它发挥才能起到去除甲醛的作用,不过这个也要看具体的情况,有的时间甚至更长.
In addition to formaldehyde, the window will be opened one week later. Only if it is fully played can it play the role of formaldehyde removal. However, it depends on the specific situation, some times even longer
1、视实际情况而定,像冬天,室内温度不高,甲醛的挥发速度慢,应每天开窗通风.而夏天,室内温度高,甲醛释放速度快，可关窗一个星期左右,让室内的甲醛全面挥发出来,再开窗进行通风。
1. Depending on the actual situation, for example, in winter, the indoor temperature is not high, and the formaldehyde volatilization speed is slow, so the windows should be opened every day for ventilation. In summer, the indoor temperature is high, and the formaldehyde emission speed is fast, so the windows can be closed for about a week, so that the formaldehyde in the room can volatilize completely, and then the windows can be opened for ventilation.
2、只要室内空间的温度不低于零下十九度的话,一般甲醛就会慢慢挥发出来,温度越高,它的释放速度就快,特别是温度超过二十五摄氏度.不过还需结合室内的污染情况来看，甲醛含 量越多的话,它的释放自然就多了.若室内属于高温度的话, -定要开窗通风,让空气中的甲醛排出室外.不及时通风,可能会导致室内的污染更加严重,就更 加难治理.
2. As long as the indoor temperature is not lower than - 19 ℃, formaldehyde will volatilize slowly. The higher the temperature is, the faster it will release, especially when the temperature is higher than 25 ℃. However, according to the indoor pollution situation, the more formaldehyde content is, the more it will release naturally. If the indoor temperature is high, windows must be opened for ventilation, Let the formaldehyde in the air out of the room. If not ventilated in time, the indoor pollution may be more serious and more difficult to control
3、在寒冷的冬季,我们往往会将窗户关起来,这样一来,室内空气将无法流通若空间有甲醛的话,容易让它挥发出来,而且还会产生别的有害气体,长时间居住,对人体会造成不小的损伤.
3. In the cold winter, we often close the windows, so that the indoor air will not circulate. If there is formaldehyde in the space, it will volatilize easily, and other harmful gases will be produced. Living for a long time will cause no small damage to the human body
4、而且将窗户关闭,空间和密室没有太大的差别,而甲醛的释放时间也要很久.而人造板材在使用过程中,往往都会源源不断的挥发甲醛,最大释放时间要十五年可见去甲醛工作是项艰巨的任务, 我们贸然居住进去,必然会造成诸多影响.
4. And close the windows, there is not much difference between the space and the secret room, and the formaldehyde release time will take a long time. In the process of using the artificial board, the formaldehyde will be constantly volatilized. The maximum release time is 15 years. It can be seen that formaldehyde removal is a difficult task. We live in it rashly, which will inevitably cause many impacts
5、我们在除甲醛的时候,虽然室内温度升高,可让甲醛释放出来,再开窗排出.但这一做法 ,只能释放大部分的甲醛,而甲醛是持续释放的,因此还需借助其他方法来治理例如摆放几盆绿植,美化空间,而且起到治理空气的作用,将有害物质转化为无机物.虽然效果不大.
5. In addition to formaldehyde, although the indoor temperature increases, formaldehyde can be released, and then discharged through windows. But this method can only release most of formaldehyde, and formaldehyde is continuously released, so other methods need to be used to control, such as placing several pots of green plants, beautifying the space, and playing the role of air control, turning harmful substances into inorganic substances. Although the effect is not good
相信大家看完以上问题，应该也了解室内去除甲醛前究竟需不需要关窗有了一定的了解了，希望会对大家有所帮助吧。
I believe that after reading the above questions, you should also know whether you need to close the window before removing formaldehyde indoors. I hope it will help you.
