First of all, although I am a mattress maker, there is no coconut palm and mountain palm material in Xingxi’s production line for a long time, so there is no interest in this article. I just hate this kind of panic caused by the general public. The behavior that brings traffic, and at the same time, I want to say a few words for the conscience of friends. As a creator of popular science in the mattress industry, I think careful verification and objectivity are two principles that a popular science writer must follow. You can not understand, but you can’t talk nonsense. Getting back to the subject, let’s talk about the title first. Have you seen the video about childhood leukemia caused by the frantically diverging palm mat on Douyin? The owner of the video inside was right, and the comments also caused widespread panic. Many mothers cut their own mattresses to find out and find peace of mind, and threw countless palm mats overnight, bringing them to the garbage disposal. Not a small trouble. Many people cut it and threw it away. Many people who don’t sell brown mats or sell so-called handmade mats started advertising, rubbing against the upcoming Double 11, another wave of merchants and consumers Carnival. But using the keywords “leukemia”, “Zongdian”, “children” to search, the only thing that seems to be true is that in 2017 a Zhenjiang girl was diagnosed with leukemia, and then the house was detected The old news of excessive formaldehyde has nothing to do with the mattress. The other is either a retelling and analysis of the incident, or similar reversal of old accounts in previous years. In recent years, many businesses have made a lot of money by creating “formaldehyde panics”: Has a miscarriage? Pot of formaldehyde! Terminally ill? Pot of formaldehyde! Can’t get pregnant? Pot of formaldehyde! Formaldehyde is really not a good thing, b Phenibut on sale ut he really doesn’t remember the leukemia pot. What is formaldehyde? Formaldehyde is a naturally occurring organic compound that exists in large quantities in nature. A small amount of formaldehyde will be rapidly metabolized by the human body. If the concentration of formaldehyde in the air exceeds 0.1 mg/m3, it will cause damage to the eyes and mucous membrane cells. In the body, formaldehyde may cause irreversible binding of proteins to DNA. Animal experiments have shown that exposure to large doses of formaldehyde increases the risk of nose and throat cancer. However, the concentration of formaldehyde in most buildings is not high enough to cause cancer. The US Environmental Protection Agency classifies formaldehyde as a possible carcinogen, and the International Agency for Research on Cancer (IARC) classifies it as a human carcinogen. (This paragraph is taken from the wiki)Key points: the eyes and mucous membrane cells, nose and throat are carcinogenic. The initial symptoms of formaldehyde stimulation are usually sore throat, itchy eyes, nasal inflammation, skin allergies, etc. Leukemia, as a blood disease, usually occurs in the bone marrow. A large number of abnormal white blood cells cause immune system problems. The initial symptoms are mainly lack of hematopoietic function, such as easy bruising, anemia, persistent fever, etc. . The causes of leukemia are complex, such as smoking, ionizing radiation, genetic factors, chemical volatile substances (benzene), etc. Overabsorption of formaldehyde may be the cause of leukemia, but whether it is the culprit causing leukemia, in fact So far there is no conclusion. (source network, thanks to the drafter)In home decoration, formaldehyde There are many sources: plywood, wooden products, wooden building materials, e China Phenibut tc. Mattress is only one part of it, is it important? important! I have also stressed the need to pay attention to the environmental protection of mattresses countless times. You can read my article on mattress purchase two days ago. But the more important thing is whether the combined concentration of all volatiles in the home meets the standard. As mentioned earlier, a small amount of formaldehyde can be metabolized by the human body, so there is no need to panic. In addition to formaldehyde, there are other chemical volatile substances in the decoration, such as benzene in paint, which is one of the real causes of leukemia. Therefore, we usually recommend to ventilate as much as possible for 3-5 months after the decoration is completed. If possible, use professional equipment to test before moving in. Let’s talk about palm mats. Cheap palm mats do use a lot of inferior glue to bond them. So every time someone asks me about a mattress of hundreds of pieces, I don’t recommend it. Cheap price definitely means cost reduction. The lower limit of the materials used after cost reduction is really not what you can imagine, but the rigorous and objective science popularization is still inferior to the alarmist rumor-defying rumors, and it is also helpless. The mats used in good mattresses are all made by 3D hot pressing process, and the fabrics have been encapsulated, basically controlling the formaldehyde emission of the entire mattress to one extreme There is no need to worry at all in the extremely low range. On the contrary, because the people who cut their own mattresses in this incident, they have to worry about other materials, such as sponge and latex, which are exposed to oxygen on a large scale. The oxidation time will be shortened sharply, which will not only af Phenibut powder wholesale fect its service life, but also may quickly Volatilize other harmful substances. Besides, how do you distinguish the quality of the mat? Many video bloggers said that after taking it apart, the fluffy ones with the white fiber structure are good, and the whole piece of hard and hard ones is glue. This is very one-sided. The white fiber structure is low melting cotton, and the fluffy is because the flat structure (layer by layer) is not stable enough. In order to save costs, such a hot pressing process usually does not use good low melting cotton. And it is very likely that in order to save costs, there may still be chemical glue in some parts. At the same time, due to the low manufacturing cost, the palm filament used is generally coconut palm with more impurities and poor quality, which is not recommended. The really good hot pressing process is 3D hot pressing. This process will form an S-shaped cross section. The picture shows that our jute is not coconut palm, but the cross section is similar. The brown mat bonded with pure chemical glue will feel the brown silk hard, and may also have white flocs, and the structure is loose. There is also the hand-woven mat that everyone suddenly starts to admire. Because the traditional process of sugar removal may not be complete, although this kind of mat does not have formaldehyde, it may be worms, so be careful. Actually speaking, it is difficult to judge purely by looking at pictures, even professionals like us, so when buying a mattress, you must confirm the craftsmanship and materials with the seller , It is the right way to ask for relevant certificates. I really don’t worry, you can choose 3D fiber, 3D fine jute and other alternatives. Formaldehyde is harmful, but it will not change the color of formaldehyde. I hope that all of us will deal with it carefully and actively, but we don’t need to panic too much and scare ourselves. Today’s decision to write this science popularization hastily, there may be mistakes, please correct me. See you next time.
