摘要
文章分别采用燃烧法、显微镜法、溶解法、红外光谱法、差示扫描量热(DSC)法,研究三聚氰胺纤维的燃烧特征、截面形态、溶解性能、红外特征峰、熔融峰温度等特性.结果表明:三聚氰胺纤维燃烧特征明显,靠近火焰不熔不缩,离开火焰立即熄灭,燃烧时略带鱼腥味;红外光谱特征峰有 1668 cm-1、1441 cm-1、1276 cm-1、808 cm-1 等;DSC 熔融峰温度为 370℃～380℃,都具有一定的特征.因此,采用燃烧法,结合红外光谱法或DSC法,可以准确定性三聚氰胺纤维.
Abstract
Combustion method,microscope method,dissolution method,infrared spectroscopy,differential scanning calorimetry(DSC)method were used to study the characteristics of melamine fi-ber about combustion characteristics,cross-section morphology,solubility,infrared characteristic peak,melting peak temperature,etc.The results showed that the combustion characteristics of mela-mine fiber were obvious,it did not melt or shrink when close to the flame,and it immediately extin-guished when it left the flame.burning with a slight fishy smell.The characteristic peaks of infrared spectrum are 1668 cm-1,1441 cm-1,1276 cm-1,808 cm-1,etc.The melting peak temperature of DSC is 370℃～380℃,which has certain characteristics.Therefore,the melamine fiber can be accu-rately determined with combustion method,combined with infrared spectroscopy or DSC method.
