| 中文摘要: |
| 以年产量超过10 000 m3的生产企业为研究对象，采用现场调研与采样检测相结合的方法，分析江苏省胶合板行业甲醛污染特征和排放系数。筛选60家典型企业，计算其甲醛排放系数R值（甲醛/胶粘剂）和K值（甲醛/产值）两个指标，结果表明，该省胶合板企业R均值为0.001 65 kg/kg，K均值为0.46 kg/万元。使用酚醛树脂胶的胶合板经济附加值最高，且对大气环境更友好，脲醛树脂胶的甲醛排放系数最高，应逐步减少使用。 |
| 英文摘要: |
| The pollution characteristics and emission coefficient of formaldehyde from plywood industry in Jiangsu were studied by site investigation combined with sampling and detection, taking the production enterprises with an annual output of more than 10 000 m3 as the research objects. Formaldehyde emission coefficient R value (formaldehyde/adhesive) and K value (formaldehyde/output) were calculated from 60 typical enterprises selected. The results showed that the mean of R value was 0.001 65 kg/kg, the mean of K value was 0.46 kg/(ten thousand yuan). Plywood with phenolic resin adhesive had the highest economic value added and was more friendly to atmosphere. Urea formaldehyde resin adhesive had the highest formaldehyde emission coefficient, which should be used less gradually. |
