本文提出了用滤膜采样,CDCL_3为溶剂,用红外光谱仪定量测定车间空气中环氧树脂粉剂和相对分子量高的环氧树脂的热降解产物的方法。仪器:用Pye Unicam SP 2000双光束红外光谱仪(具有参比池)测定环氧树脂的芳香基团及热降解产物相对分子量高的部分。用1cm光程长度的封闭的KBr池。利用芳香化合物在1510 cm~-处具有强吸光度进行分析。在
In this paper, a method for the quantitative determination of the thermal degradation products of epoxy resin powder and high molecular weight epoxy resin in the air of workshop by using CDCL_3 as solvent and CDCL_3 as solvent was proposed. Instrument: The aromatic groups of the epoxy resin and the portion of the thermal degradation product with a relatively high molecular weight were determined using a Pye Unicam SP 2000 dual-beam infrared spectrometer (with a reference cell). Closed KBr pool with 1 cm path length. Aromatic compounds with strong absorbance at 1510 cm ~ - were analyzed. in
