很多人知道甲醛只是因为甲醛来自于装修污染的空气。如果你是这么想的，再想想。事实上，甲醛不仅适用于某些装饰材料，还适用于许多其他方面。当然，我们也有自己对甲醛的认识，甲醛究竟是从什么方面来的呢?让我们互相了解一下。
Many people know that formaldehyde only comes from the air polluted by decoration. If you think so, think again. In fact, formaldehyde is not only suitable for some decorative materials, but also for many other aspects. Of course, we also have our own understanding of formaldehyde. What is the origin of formaldehyde? Let's get to know each other.
,空气
First of all, air
甲醛也是一种严重的环境污染。各种甲醛存在于用于墙板或天花板的装饰材料中。另外，这部分甲醛主要用于人造板或其他含甲醛的纤维板、刨花板装饰材料。它也能在室外蒸发，比如粘在墙上的布料或墙纸上的材料，以及其他他的颜料可能会释放出甲醛的材料。当然，这些家用产品也会蒸发掉所有的甲醛。燃烧时也会释放甲醛。一般来说，一些有机材料也会释放甲醛。一些香水或驱蚊剂也含有甲醛。我们必须一直非常小心。
Formaldehyde is also a serious environmental pollution. All kinds of formaldehyde exist in decorative materials used for wall panels or ceilings. In addition, this part of formaldehyde is mainly used for wood-based panel or other formaldehyde containing fiberboard and particleboard decoration materials. It can also evaporate outdoors, such as materials that stick to wall cloth or wallpaper, and other materials that his paint may release formaldehyde. Of course, these household products will also evaporate all formaldehyde. Formaldehyde is also released when burned. Generally speaking, some organic materials also release formaldehyde. Some perfumes or mosquito repellents also contain formaldehyde. We have to be very careful all the time.
其次,衣服
Secondly, clothes
甲醛可以在白色或无衬里的衣服中找到，特别是在一些牛仔裤中，可以100%抗皱。收缩服基本上是不含铁的，甚很多棉制品也含有甲醛，因为只有甲基醛更容易固定。
Formaldehyde can be found in white or unlined clothing, especially in some jeans, which can be 100% wrinkle resistant. Shrink suits are basically free of iron, and even many cotton products contain formaldehyde, because only methylaldehyde is easier to fix.
第三,食品
Third, food
白色冷冻食品可能含有甲醛，如新鲜或防腐剂。
White frozen foods may contain formaldehyde, such as fresh or preservatives.
通过以上的介绍，我认为我们应该对甲醛的来源有一个清晰的认识。要特别注意甲醛从生活的各个方面，所以想要甲醛，就有必要特别注意这些方面，并采取适当的预防措施。
Through the above introduction, I think we should have a clear understanding of the source of formaldehyde. Special attention should be paid to formaldehyde from all aspects of life, so in order to eliminate formaldehyde, it is necessary to pay special attention to these aspects and take appropriate preventive measures.
