<p>where to buy pvc plastic wall sheet for bathroom formaldehyde content What are the requirements & ldquo;? Formaldehyde-free floor & rdquo; do we really formaldehyde-free laminate flooring are formaldehyde-free?. Laminate flooring formaldehyde mainly from the industrial glue, now the state has a clear requirement floors formaldehyde content, flooring manufacturers are also more emphasis on this aspect. National standards are based on the business called "interior decoration materials and products Laminate flooring formaldehyde emission limits" in the relevant standards. Earlier local Consumers Association jointly launched the survey found that in 15 of laminate flooring samples, only two samples formaldehyde emission of less than & le; 0.5mg / L, most of them just meet the minimum standards that is & le; 1.5mg / L. And strengthen the floor, 13 parquet in 10 formaldehyde emission 0.3mg / L or less, far better than the existing national standards.</p> <p>This finding is also reflected in the market. Laminate flooring formaldehyde: Usually solid wood flooring composite floor than the formaldehyde content lower, mainly due to less use of plastic. But the price difference is also great flooring, laminate flooring one square meters priced at 100 yuan, while the lowest wood flooring have more than 200 yuan. Laminate profiles wood polymer, laminate flooring, parquet three. Among them, the hazards of formaldehyde wood flooring minimum, but there are high prices, complex installation and maintenance processes using more troublesome problems. Formaldehyde laminate flooring, solid wood flooring because of the production, the installation process requires adhesive glue, relatively speaking, the formaldehyde content will be higher.</p> <p>In laminate flooring formaldehyde in the standards, the detection method is not the same as the same type of product, the value of the unit is not uniform, not the same level of delineation. Since the standard and more standards are not uniform, coupled with the current implementation of sheet metal and flooring industry enterprise inspection system, which to some unscrupulous companies created hype the concept of marketing space. Laminate flooring manufacturers are the largest use of urea-formaldehyde glue, accounting for 70% -80%, while the use of urea-formaldehyde adhesive sheet is unstable and build a sun deck products formaldehyde emission factors. Some manufacturers to meet the inspection, but only short-term compliance, through some special chemical treatment means so that the sheet of laminate flooring in the short term is very low formaldehyde emission. However, formaldehyde release cycle plate for 8--15 years, after a period of time, formaldehyde emission has uncertainty will appear.</p>
