What is formaldehyde? Is solid wood flooring formaldehyde?
Solid wood flooring is the material that everyone often uses to decorate the house. But the solid wood flooring has formaldehyde. Many of my friends still don’t know. Let’s let the decoration of the home of the decoration network introduce it to everyone. Does the solid wood floor have formaldehyde? First understand what is formaldehyde, solid wood floor has formaldehyde? What is its test method, and solid wood floor with formaldehyde? Xiaobian will introduce some solid wood flooring with formaldehyde. First, the introduction of formaldehyde 1, formaldehyde, chemical formula HCHO or CH2O, the formula amount of 30.03, also known as formic aldehyde. A colorless gas with a special irritating odor that has a stimulating effect on the eyes and nose. The gas has a relative density of 1.067 (air = 1) and a liquid density of 0.815 g/cm3 (-20 ° C). Melting point -92 ° C, boiling point -19.5 ° C. Soluble in water and ethanol. The concentration of the aqueous solution is up to 55%, usually 40%. It is called formalin, commonly known as formalin, and is a colorless liquid with a pungent odor. 2, there is a strong reduction, especially in alkaline solutions. It can burn, and the vapor forms an explosive mixture with air. The explosion limit is 7%-73% (volume). The ignition temperature is about 300 °C. 3. Formaldehyde can be obtained by dehydrogenation or oxidation of methanol under the catalysis of silver, copper or the like, or by hydrocarbon oxidation products. Used as a pesticide and disinfectant, raw materials for phenolic resin, urea-formaldehyde resin, vinylon, urotropine, pentaerythritol and dyes. Second, the solid wood has formaldehyde 1, pure solid wood flooring Pure solid wood flooring is directly processed from the whole piece of woodwork. There are no other additives. In addition to the surface lacquer, it is also a favorite floor. The amount of formaldehyde released from this floor is almost negligible and can be considered as zero formaldehyde floor. 2, solid wood composite floor Solid wood composite flooring is now widely used in homes. It is made of three or more layers of solid wood chips, which are glued and pressed into a substrate, and the surface is pressed against a high-quality wooden veneer. The base material of the solid wood composite floor is multi-layer plywood, the adhesive is mostly urine aldehyde resin glue, and the formaldehyde release period is up to 15 years. The surface of the floor is painted with paint to prevent the release of formaldehyde. There is no formaldehyde release, but formaldehyde is released from the bottom and sides. 3, solid wood composite floor is now laminate flooring Reinforced laminate flooring When we buy, we must choose the big brand, because the formaldehyde content will be lower, it is made of high-density fiberboard as the substrate, the surface has decorative layer, wear layer, back layer plus balance layer, high temperature Pressed floor. The main material high-density fiberboard is made by pressing together the adhesive of wood fiber and urine aldehyde resin glue, and the urine aldehyde resin glue releases formaldehyde for a long time. Adhesives in high density fiberboard used as substrates are the main cause of formaldehyde release. If there is no furniture in the room, the formaldehyde detection value of the new room with laminate flooring is generally below 0.08 mg, and the formaldehyde detection value of the large brand of laminate flooring is even lower. Third, solid wood floor formaldehyde test method On the one hand: the formal flooring company's product packaging is printed or labeled with clear Chinese signs, such as the name of the manufacturer, the site, the implementation of the standard number, product name, specifications, wood name, grade, quantity and batch number, etc.; The above related information can be considered as inferior floor or triple-no composite floor, and it is more likely to embed "poisonous bombs". More care should be taken on the packaging, all in English, and it may be a "smoke bomb" that small manufacturers deceive consumers. On the other hand, consumers can ask the floor sales staff for a small sample before signing the bill. After going home, soak in boiling water for 3-5 minutes, and smell the smell. Good laminate flooring generally does not smell pungent odor due to low formaldehyde emission. Once the smell is more irritating, and even the eyes feel uncomfortable, it can be basically determined that the formaldehyde in the composite floor exceeds the standard. The above is the solid wood floor with formaldehyde, the above has already stated that there is a possibility that formaldehyde is present on the solid wood floor, and the solid wood floor has formaldehyde expression method we have already understood, so this solid wood floor has formaldehyde, we can still have some Solve and prevent. There are also a lot of decoration information that can help everyone, and friends continue to pay attention.
