In recent years, people's emphasis on healthy living has made the brown mattress made of natural materials popular among consumers. Recently, in the results of a mat comparison test published by the Zhejiang Consumer Rights Protection Commission, in the 20 batches of brown mattress products, the formaldehyde emission of 5 batches of brown mattresses exceeded the national standard, and the formaldehyde exceeded the standard rate. 1/4. Today, Xiaobian will take you to see why the brown mattress made of natural materials has excessive formaldehyde and the precautions for purchasing brown mats in daily life.
At present, the popular brown mat raw materials on the market are mainly mountain brown and coconut palm. The mountain brown is the mountain brown fiber extracted from the mountain palm tree. The coconut palm is the coconut peel fiber. The natural raw material is used by the consumers. An important source of this impression of environmental protection. Since the raw materials used are so natural, why do some of the mats made of natural materials exceed the standard? From a professional point of view, the formaldehyde mat exceeds the standard, most of which is due to the use of excessive glue to bond, this is formaldehyde. An important source. Everyone thinks that brown is a natural material and will be very environmentally friendly. But in fact, what brown fiber is, brown fiber is like a long weed in the mountains, so thick fiber, want to let them obey the post as a mattress, can only be glued with glue, this glue may contain formaldehyde.
Of course, chemical glues with excessive formaldehyde content are not the only choice for mat adhesives. There are currently two alternative adhesives that are widely used in large-size mat manufacturers. One is to use a natural latex that is cut from the rubber tree for bonding; the other is to use a low-melting fiber as a binder, and the brown fiber and the low-melting fiber are mixed and heated, and the low-melting fiber is melted and stirred to make the low-melting fiber. It is entangled with brown fiber and then cooled down. This is a purely physical process that does not involve chemical agents. Formaldehyde has the property of stabilizing glue and is widely used in chemical glue. At present, many big brands no longer use chemical glue as a binder.
In the Tmall flagship store, a brand with a serious formaldehyde standard also claims to use low-melting fiber as a binder. It may be because these brands incorporate chemical glue in the production process. In the process of low-melting fiber as a binder, the most expensive is the low-melting fiber, so it is suspicious that these brands are not doped with glue. In order to reduce costs, some small brands will use printed fabrics as fabrics. The dye on the surface of printed fabrics is also one of the sources of formaldehyde. The big brands are commonly used for knitted fabrics, and the price is about 10 times that of printed fabrics. "Hanging sheep head selling dog meat" may also be one of the reasons for the excessive formaldehyde in these brands. A domestically produced production line with low-melting fiber as a binder needs millions, and the price of imported production lines is more than 10 million yuan. In contrast, the cost of using glue as a binder is much lower and the process is simpler. Such high equipment investment may make some small brands discouraged and turn to "selling sheep's head to sell dog meat". The publicity uses a low-melting process, and in fact, chemical glue is still used as a binder.
Brown pad purchase tips
First of all
To see the product manual and logo, it should be marked with the trademark, Chinese factory name, factory address, and product name;
Second
At the time of purchase, the quality inspection report can be obtained, and the product safety factor of the quality inspection report and the qualified product will be higher;
Shopping should try to choose a reputable seller and ask for relevant shopping vouchers so that they can effectively protect their legitimate rights and interests after quality problems occur. The quality of online shopping mattresses is mixed, and consumers should be cautious in purchasing reputable online sales channels.
At last
Smell the smell of the mattress if there is a irritating smell. If there is a zipper on the side of the mattress, try to open it carefully and check the internal materials.
Most consumers have a misunderstanding. Consumers buy mats mostly because they are harder than spring soft mattresses, so the standard of purchase is “harder and betterâ€. In fact, most of these hard mats use urea-formaldehyde glue as a binder, but it is not safe. .
In addition, if you don't feel relieved after buying the mat, you can put it in the sun, because the volatilization temperature of formaldehyde is 19.5 degrees Celsius, and exposure can accelerate the evaporation of formaldehyde.
