摘要
根据物理吸咐作用,在脲醛树脂中加入银杏木炭,测定和分析树脂中游离甲醛含量的变化,结果发现,当木炭与树脂质量比达到1:12.5,树脂中游离甲醛的含量可以降低50%左右,使其达到国家标准。
Free formaldehyde in the urea-formaldehyde resins was absorbed by the ginkgo-activated carbon. The change of free formaldehyde contents were measured and analysisd in the resin,as a result,we found when the charcoal and resin quality ratio attain 1:12.5,a content of leaving the formaldehyde to be as low as 50%, making it satisfies a national standard completely.
