聚氨酯合成革绿色清洁化生产发展趋势分析

Analysis on Development Trend of Green and Clean Production of Polyurethane Synthetic Leather

我国部分合成革企业将优化工艺规范的重心放在了绿色清洁方面,并采取了物料运输通道、自动配料、车间全封闭生产等方面的清洁生产措施,从而有效降低了生产过程中废气废料的排放。生产过程中的废气对工作人员有一定影响,造成工作人员的身体健康问题。因此,为了让废气在烘干工序和涂台上挥发,可以在涂台上方装设吸风罩,或者将人工加料改为自动加料,以减少溶剂的挥发,实现溶剂的回收利用,保护生产工作人员的身体健康,提高资源的循环利用,减少对环境和空气的污染。

Some synthetic leather enterprises in my country put the focus on optimizing process specifications on green cleaning,and adopted clean production measures such as material transportation channels,automatic ingredients,and fully enclosed production workshops,thereby effectively reducing waste gas and waste in the production process Emissions.In the production process,exhaust gas has a certain impact on the staff,causing health problems for the staff.Therefore,in order to allow the exhaust gas to be used in the drying process and the coating table,a suction hood can be installed above the coating table,or manual feeding can be changed to automatic feeding.This way,the volatilization of the solvent can be effectively reduced and the solvent recovery can be achieved Utilize,protect the health of production workers,improve the recycling of resources,and reduce environmental and air pollution.
