Whether the board is good or not, mainly depends on the environmental protection grade. Good sheet metal has a good home environment, and formaldehyde emission must be within the national standard. After all, health is priceless!
Many owners and friends are recommended to be called Ou Song board when they are renovating. The custom company is very recommended. The so-called environmental protection material is similar to logs. The emerging board made of European pine is formaldehyde-free and pollution-free. The texture is beautiful and beautiful, and it is used to make the wall background beautiful and natural.
Osong board, its internationally known name is OSB, the full name of Oriented Strand Board oriented strand board, is a kind of building decoration material, which is processed by special equipment with small diameter material as raw material to grow 40-100mm, width 5-20mm, thickness 0.3- 0.7mm flank, made by drying, screening, sizing, directional paving, continuous hot pressing and other processes. The surface flank is arranged in the longitudinal direction, and the core flank is arranged in the horizontal direction. This criss-crossing arrangement reorganizes the wooden texture structure, completely eliminating the influence of the internal stress of the wood on the processing, making it extremely easy to process and moisture-proof. Sex. Since the interior of the Ozon board is oriented, there are no joints, no gaps, cracks, good overall uniformity, and the internal bonding strength is extremely high.
But is the Ozon board really zero pollution? I am going to say something today, I am afraid I will let everyone down. Even though the merchant recommended the sky, but after all, the Ou Song board is also a wood-based board. As we all know, formaldehyde is not a necessary direct product in the decoration, paint and adhesive. In the production process of wood-based panels, it is necessary to use the adhesive. The most commonly used adhesive is urea-formaldehyde resin. There is a large amount of formaldehyde residue in the production process of urea-formaldehyde resin. It is called free formaldehyde. This part of free formaldehyde is used in paint operation. Will be released, this is the direct source of formaldehyde damage. Of course, many merchants will say that the Ou Song board wardrobe does not contain formaldehyde, because the Ou Song board wardrobe does not use urea-formaldehyde resin. But in fact there are too many formaldehyde-free adhesives, such as polyisocyanate resin MDI, but these things now seem to be unable to quickly replace urea-formaldehyde resin.
Of course, we do not deny that Ou Song board has solved many problems of blockboard, plywood and fir finger joint plate, and made up for its defects such as aphids, deformation and instability. However, when building a house abroad, it is only used to make the wall lining, or the wooden structure of the base of the house. Domestically, the lining of OSB board as a decorative material at least faces two problems. First, is the domestic manufacturer strictly using environmentally friendly glue? Second, the inner liner is used as a decorative material for the skin, and if it is contaminated, it is more volatile and pollutes the air.
Secondly, the so-called Ou Song board, only China called him Ou Song board, in fact, the name "Ou Song" is a Chinese building materials (group) registered in the China Trademark Office, and fabricated a story "using European pine as a "Ingredients", in fact, is that the Chinese made a name by themselves and made a story to lie to the Chinese. It sounds like it is tall. It is just a common building material outside China. That is to say, this thing is a kind of thing. Common building materials like sandstone, cement and gypsum board, there are also a large number of manufacturers in China, imported and domestic, imported OSB (Ou Song board) raw materials for perennial pine, domestic OSB is 3- 5 years old poplar. Of course, these are indeed used for interior decoration, house construction, furniture production, and packaging materials, but they are excessively used as high-grade decorative materials to promote their value.
And this so-called Ou Song board, which is the principle of particle board, is a bit more popular. It just puts all kinds of fast-growing wood shavings together with glue. It was first invented by Armin Elmendorf in California in 1963 because of his The performance is relatively stable and practical, so it has been popular in the world for many years, and has been continuously improved to become a popular product with certain waterproofness, insect proof, and easy processing and cutting. At present, the world's largest output of OSB is produced by the United States. Produced in the Canadian region because these two North American countries are rich in timber resources. And implement strict environmental standards.
No matter how the board is decorated, the air quality problems such as formaldehyde pollution should be given priority attention. As long as the adhesive glue and spray paint are used, there will be formaldehyde, which has to be paid attention to. 70% of the diseases are related to air quality. Formaldehyde can also cause cancer to be the number one stealth killer in the home. It is recommended to use formaldehyde detection kit to test the formaldehyde concentration before check-in.
What should I pay attention to when choosing the Ozon board? Choosing a flat surface, it is better to pick up a certain amount of Ou Song board. The pressure strength of this kind of sheet production is high, the internal gap is small, compact, and the structural strength is naturally good. In addition, the larger the blade of the Ozon board, the better, and the upper and lower layers are oriented in a criss-crossing orientation.
