Biological glue to achieve no formaldehyde, from the theory and technology can be done, formaldehyde is to increase the viscosity of glue, adhesion of the excellent material. Under the current technical conditions, the composite floor of the density, water swelling rate of technical indicators need to use formaldehyde to ensure quality and stability. The use of non-formaldehyde-free adhesive flooring products first cost higher, followed by leaving formaldehyde, the overall performance of the floor is difficult to stabilize, may not be able to meet the national standards of wood-based panels.
In theory, pure solid wood flooring does not contain formaldehyde, composite flooring if the use of non-formaldehyde glue can be achieved with natural solid wood flooring as aldehyde. But the actual detection found that natural wood may also contain less than 0.1 mg per liter of trace aldehydes. And the existing conditions can not detect formaldehyde content, can only show that its content is very low and not non-existent. "Even if the use of formaldehyde-free adhesive floor, can only show that it did not add formaldehyde in the production process, but does not mean that the product itself does not contain formaldehyde.
And wood flooring will be able to do this, come take a look at it.
