<p>mention formaldehyde, people the condition that coloured changes. In floor course of study, the formaldehyde that we say releases a quantity to exceed bid, basically be to be aimed at aggrandizement compound floor.anti scratch composite wood porch deck Because of the characteristic of aggrandizement floor structure, must use glue, and formaldehyde is contained in glue.</p>
<p>According to introducing, aggrandizement is compound the floor is comprised by 4 structures commonly, floor surface is wear-resisting layer, main by 3 oxidation 2 aluminium are comprised, have very strong wearability and hardness.how much does tongue and groove stockade fence cost It is adornment layer then, this is the paper of macerate of colophony of amine of a warp density. Still having is basic level, main structure is medium high density beaverboard, via high temperature, high pressure and agglutination processing. Finally is balance layer, it is a kraft, have particular strength and ply, and dip with colophony,plastic wood composite floor decking in Las Vegas moistureproof station reachs since board metabolic action. Plywood of solid wood is base material with plywood, rise veneer agglutinate.</p>
<p>Aggrandizement floor and solid wood joins a floor board Through agglutinate of glue sticky agent, can produce formaldehyde, glue sticky dose is little, formaldehyde of poor; of function of floor waterlogging caused by excessive rainfall is more, agglutinate prison is spent taller, the floor contains formaldehyde itself inevitable. the advantages of wood plastic decking center of building materials of chemistry of qualitative check courtyard to say, “ floor production is commonly used is Niao aldehyde glue and phenolic aldehyde glue, content of formaldehyde of phenolic aldehyde glue is low, but the price is high. The sizy quality that place of ” production company uses is uneven, the glue with poor quality can be made piec Formaldehyde releases a quantity Exceed the floor of mark.</p>
