浸渍胶膜纸饰面纤维板-甲醛释放量数据

浸渍胶膜纸饰面纤维板-甲醛释放量数据甲醛释放量测定-1m³气候箱法，将规定表面积的样品放入规定温度、相对湿度、空气流速和空气置换率的气候箱内，样品释放的甲醛与箱内空气混合。在规定的的各个时间段，以蒸馏水作为吸收液，吸收规定体积混合空气中的甲醛，直至箱内混合空气中甲醛浓度达到稳定状态。测定吸收液中的甲醛量及抽取空气体积。根据甲醛质量浓度和对应吸光度绘制标准曲线获得斜率f，以蒸馏水的吸光度为空白值Ab，以吸收液的吸光度为测量值As，则甲醛含量为G=f×（As-Ab）×Vsol，稀释倍数为1，甲醛释放量即为抽取空气体积内的浓度为c=G/Vair，最终结果为当气候箱内达到稳定状态时最后四次测定的浓度的平均值。GB18580-2017标准要求室内装饰装修材料人造板及其制品中甲醛释放限量值为0.124mg/ m³，限量标识为E1。合格率计算为不合格数据与全部录入数据比较取整得到。

Formaldehyde Emission Data for Melamine-impregnated Film-faced Fiberboard: Formaldehyde Emission Test via 1 m³ Climate Chamber Method. Specimens with specified surface area are placed into a climate chamber with controlled temperature, relative humidity, air flow velocity and air exchange rate. Formaldehyde released from the specimens mixes with the air inside the chamber. At specified time intervals, distilled water is used as the absorbing solution to collect formaldehyde from a predetermined volume of the chamber's air mixture until the formaldehyde concentration in the chamber's air stabilizes. The formaldehyde content in the absorbing solution and the volume of extracted air are measured. A standard curve is plotted based on formaldehyde mass concentration and its corresponding absorbance to obtain the slope f. The absorbance of distilled water serves as the blank value Ab, while the absorbance of the absorbing solution is the measured value As. The formaldehyde content is calculated as G = f × (As - Ab) × Vsol, with a dilution factor of 1. The formaldehyde emission concentration within the extracted air volume is c = G/Vair. The final result is the average of the concentrations measured in the last four tests when the climate chamber reaches a stable state. According to GB 18580-2017, the limited formaldehyde emission value for wood-based panels and their products for interior decoration materials is 0.124 mg/m³, with the limit label being E1. The qualification rate is calculated by comparing the number of unqualified data against the total number of entered data and rounding the resulting proportion.
