The new house bought by Mr. Zhang was renovated in June this year. After that, he participated in the free quality inspection of the city quality supervision bureau in September. Today, he received the test results.
The formaldehyde exceeded the standard twice, and Mr. Zhang did not dare to live. According to the results announced by the Quality Supervision Bureau, 330 households were tested, 204 were qualified, 126 were unqualified, and the unqualified rate was as high as 38%. Nearly 40% of new homes will have excessive formaldehyde, which is what is going on?
Chen Zhaogang, a quality inspection engineer in Xiangcheng: As long as it is a wood-based panel, it will use glue more, then it will have formaldehyde.
A large part of the original standard was caused by furniture. Nowadays, there are many kinds of plates in the furniture market, which are divided into high-density boards, medium-density boards, particle boards, ecological boards, etc. However, many merchants clearly say that they are formaldehyde-free boards. How can this problem occur?
Chen Zhaogang, the quality inspection engineer of Xiangcheng: This kind of three-plywood five-ply board, the glue is used more, the formaldehyde content is easy to exceed the standard. When we buy, we must pay attention to the bottom of the drawer, the back of the cabinet, the side panels, try to use less plywood, three plywood, five plywood.
In fact, these plates are glued with wood fibers, and the pressed plates need to use a large amount of glue containing formaldehyde, so once the production process is not enough, the test results will exceed the standard.
Chen Zhaogang, the quality inspection engineer of Xiangcheng: This bedside table, as our furniture inspection, has no veneer inside, which is not allowed, so it is unqualified to say that it is necessary to seal the sheet used in furniture. On both sides, both sides are sealed. This is a must in our national standards.
Experts said that if the panel furniture is just painted with a good seal and does not do any treatment inside, it will lead to excessive formaldehyde emission. In contrast, the test results of solid wood furniture are much better, and formaldehyde is basically not exceeded.
How do you distinguish between solid wood furniture and sheet furniture?
The sheet furniture is placed on two bedside tables. We look like wood from the outside. The material is similar, but we can see it when we turn it around. It uses a three-ply board for this backboard. It is very very thin and knocks. You can listen to this sound... When you knock it, you can see the obvious jitter on this backplane.
Therefore, you must be careful when you choose the furniture of Sioux City.
