With the use of wooden door products indoors, paint pollution of various wooden door products has also been brought into the home life. Due to the fear of formaldehyde, consumers can't help but look at the "zero formaldehyde" wooden door "zero formaldehyde" furniture. Is there a "zero formaldehyde" wooden door? The industry insiders said that "zero formaldehyde" is actually a gimmick. According to the current manufacturing process, it is impossible to realize "zero formaldehyde" in the wooden door, so how to reduce the wooden door product during daily decoration and use. What is the amount of formaldehyde released?
Formaldehyde in wood products
At present, in the wood product research system, there are almost no research papers on the quantitative nature of formaldehyde hazard. The test methods for formaldehyde content are classified into various standards. There is no uniformity. The standards of China are based on Japan and Europe, referred to as e1 and e2. It can only be said that e1 is better than e2, but it is much better, and it has no effect on the degree of health. The testing process is also very complicated, and the results of different people's tests are biased. The current testing methods are not perfect. E0 is basically a concept hype, flickering, so if it is sensitive to formaldehyde, the best solution is to not use wood-based panels made of urea-formaldehyde glue.
There is a disconnection problem in the wood product supervision system. The control of woody formaldehyde is basically based on sampling and sample sampling: sampling, once a year, the factory will say hello, do a good job, prepare a "sample"; send samples, not to mention After processing the sample and then sending it to the sample, there is no end to it. Therefore, the general test report can not guarantee the formaldehyde problem of wood products (the test report will indicate that it is responsible for the "sample"), similar to a diploma, the actual number of materials is not easy to say, only to show that this company is still a bit Strength. Of course, this thing can still be used as a basis for a lawsuit.
The formaldehyde in the wooden door is distinguished from the material and structure, and the wooden door is divided into a wooden door and a composite door. In terms of formaldehyde, the composite door is much larger than the original wooden door.
For the original wood door, there are pure wood doors: all parts are made of a single wood board, without adhesive compounding (may use urea-formaldehyde glue), the parts are connected by gutter structure (such as with adhesive reinforcement, there is no error Use urea-formaldehyde glue, apply puzzle glue). Composite wood door: Adhesive bonding between the parts themselves and or parts (possibly with urea-formaldehyde glue).
Therefore, although the original wooden doors use natural raw wood, it is difficult to avoid the use of adhesives, and it is difficult to buy pure original wooden doors on the market, but the problem of formaldehyde is relatively easy to control.
For the demand of luxury, you can customize the pure wood door, reduce the chance of using chemical adhesives, such as glued with glue, requires the use of glue.
For the composite door, it is complicated. Because of the invention of urea-formaldehyde glue, it has designed and produced all kinds of wooden wood-based panels (MDF, plywood, particleboard), and there is a composite door. Therefore, formaldehyde has penetrated into the composite door. Inside the bones, the inevitable existence is only more or less.
Moreover, it is possible to use urea-formaldehyde glue in the composite door assembly process and the skinning process, so formaldehyde control is difficult.
In terms of the lethality of formaldehyde
MDF>Particle Board>Plywood
Choose composite doors made of plywood and natural wood, and pay special attention to the material of the door frame and door line is also plywood and natural wood. Write this to the order contract:
(1) To see the cross-section sample provided by the seller in the store, the door page and the door frame are seen together, and the cross-section can be used to know which materials are used.
(2) After the wooden door is delivered to the home, be sure to check it before installation, lock the hole, and assemble the hinge. You can see the internal structure of the door page. If you click on the bottom side of the door, you can see if it is used. Plywood. The door frame can be seen from the cut surface. If not, claim again from the merchant.
