摘要
影响乙二醇产品紫外透光率物理因素有空气、氮气和阳光照射,为探讨各物理因素对乙二醇产品紫外透光率衰减程度影响,利用氮气和空气分别对乙二醇产品做鼓泡实验、阳光照射和空气中静置乙二醇产品实验,结果表明,乙二醇产品在氮气环境中,紫外透光率衰减最慢,在空气鼓泡环境中,紫外透光率衰减最快。影响乙二醇产品紫外透光率化学因素有精馏系统加碱、精馏系统不加碱、乙二醇加氢反应、树脂质量提升,为探讨各化学因素对乙二醇产品紫外透光率衰减影响程度,对4种化学处理后得到乙二醇产品做空气鼓泡衰减实验,结果表明,乙二醇加氢后产品紫外衰减最慢,精馏系统不加碱紫外衰减最快。
Physical factors affecting the ultraviolet transmittance of ethylene glycol products include air,nitrogen and sunlight irradiation.In order to explore the influence of each physical factor on the attenuation degree of ultraviolet transmittance of ethylene glycol products,nitrogen and air were used to conduct bubble experiment,sunlight irradiation and static ethylene glycol products in air respectively.The results showed that,the uv transmittance of ethylene glycol products decays slowest in nitrogen and fastest in air bubbling.The chemical factors affecting the uv transmittance of ethylene glycol products include alkali addition in distillation system,alkali addition in distillation system,ethylene glycol hydrogenation reaction,and resin quality improvement.In order to explore the influence degree of each chemical factor on the attenuation of uv transmittance of ethylene glycol products,air bubble attenuation experiment was conducted on ethylene glycol products after four chemical treatments.The results show that the uv attenuation of ethylene glycol hydrogenation product is the slowest,and the uv attenuation of distillation system without alkali is the fastest.
