Determination of the extraction method is bone dry wood-based panels extracted amount of formaldehyde measured results are almost independent of temperature; decoration wall panel material distributor measured climate box method is the amount of formaldehyde released specimen of the steady state of the air, which is measured at room temperature get on. Similar drier climate chamber's principles and laws, to reflect the actual use can release formaldehyde emission, but the temperature is not the same, formaldehyde and test results actually released a difference. "That is our country there is no clear standard for best wood fence pickets for sale formaldehyde emission testing standards wooden floors is carried out at room temperature, formaldehyde emission temperature after." Chen Xiaofeng said that in different regions, different families of non-uniform temperature geothermal for geothermal floor again setting standards is difficult. |
