技术领域Technical field
本发明涉及空气过滤领域,特别涉及一种核孔膜纱、核孔膜纱窗及核孔膜纱的制备方法。The invention relates to the field of air filtration, in particular to a method for preparing a nuclear aperture film yarn, a nuclear aperture film screen and a nuclear aperture film yarn.
背景技术Background technique
空气与人类的生存息息相关,它直接参与人体的气体代谢、物质代谢和体温调节等过程。一个人每天呼吸的空气约为1万多升,折合质量约为12.9kg,约为每天所需食物和饮水量的10倍。洁净空气是人赖以生存的必要条件之一,一个人在五个星期内不吃饭或5天内不喝水,尚能维持生命,但超过5分钟不呼吸空气,便会死亡。Air is closely related to human survival. It directly participates in the process of gas metabolism, substance metabolism and body temperature regulation. The air that a person breathes every day is about 10,000 liters, and the equivalent mass is about 12.9 kg, which is about 10 times the amount of food and water needed per day. Clean air is one of the necessary conditions for people to survive. If a person does not eat for five weeks or does not drink water for five days, he can still maintain his life, but if he does not breathe the air for more than 5 minutes, he will die.
然而随着现代工业和交通的迅猛发展,烟尘和汽车尾气等的排放量,超越了大气的自净界限,接踵而至的是一个十分严峻的问题——大气污染。近年来,国际上一些室内环境专家提醒人们,在经历了工业革命带来的“煤烟型污染”和“光化学烟雾型污染”后,现代人正进入以“室内空气污染”为标志的第三次污染时期。由于人们长期在室内工作,同时各国却普遍采取建筑节能措施,减少空调换气次数,以致有些人出现头疼、咽喉不适、咳嗽、平衡感觉失调、倦怠、红斑、皮肤干燥等综合症状,这种病理反应被称作“病态建筑综合症”或“办公室综合征”。However, with the rapid development of modern industry and transportation, the emissions of soot and automobile exhausts have surpassed the self-cleaning limit of the atmosphere, followed by a very serious problem - atmospheric pollution. In recent years, some indoor environmental experts in the world have reminded people that after experiencing the “soot-type pollution” and “photochemical smog-type pollution” brought about by the industrial revolution, modern people are entering the third category marked by “indoor air pollution”. Secondary pollution period. Because people work indoors for a long time, at the same time, countries generally adopt building energy-saving measures to reduce the number of air-conditioning changes, so that some people have headaches, throat discomfort, cough, balance dysfunction, burnout, erythema, dry skin and other symptoms. The response is called "sick building syndrome" or "office syndrome."
室内空气污染物主要来自于室外空气中的侵入污染物和室内建筑及装潢材料、现代办公设备和人体自身所产生的污染物,悬浮在空气中的固态粒子或液态小滴物质统称为气溶胶,气溶胶是大气不可或缺的组成部分,无论是室外污染物还是室内污染物,均以气溶胶形式存在于空气 中。室外空气中的污染物是通过房屋的门、窗进入到室内的,它主要来源于燃料燃烧、工业生产和交通运输,所产生的对人体有害的污染物是PM2.5、SO2、NO2和CO等。综上所述,室内空气中包含大量危害人体健康的气溶胶污染物,它们同时来自于室外和室内,主要包括可吸入颗粒物、各种有害气体及细菌和病毒。人体通过呼吸作用将污染物吸入体内,结果引发呼吸道疾病、癌症等。如何采取有效措施,降低室内污染源的发生,从而提高人的生存质量,是在当前大面积空气污染无法在短期内根治的背景下急需解决的重要问题。Indoor air pollutants mainly come from intrusive pollutants in outdoor air and indoor building and decoration materials, modern office equipment and pollutants produced by the human body. Solid particles or liquid droplets suspended in the air are collectively referred to as aerosols. Aerosols are an integral part of the atmosphere, whether in outdoor or indoor contaminants, in the form of aerosols in the air. The pollutants in the outdoor air enter the room through the doors and windows of the house. It mainly comes from fuel combustion, industrial production and transportation. The pollutants harmful to the human body are PM2.5, SO 2 and NO 2 . And CO and so on. In summary, indoor air contains a large number of aerosol pollutants that are harmful to human health. They come from both indoors and indoors, mainly including inhalable particulate matter, various harmful gases, and bacteria and viruses. The human body inhales pollutants into the body through respiration, resulting in respiratory diseases, cancer, and the like. How to take effective measures to reduce the occurrence of indoor pollution sources and improve people's quality of life is an important problem that needs to be solved urgently in the context that large-scale air pollution cannot be cured in the short term.
