随着我国高分子工业的迅速发展,塑料制品的应用非常广泛。对塑料生产,特别是县、社一级的中小型塑料厂,如何做好职业危害的预防工作,日益引起重视。本文介绍一种挤塑机使用的排气罩,由于这种排气罩设计比较合理,有效地控制了塑化过程产生的有害气体,防止了职业病的发生。潮安塑料厂,主要生产聚氯乙烯全塑凉鞋。塑化过程中,加热至180～195℃,塑化2～3次,由于增塑剂部分挥发及一些树脂分解,挤塑机出料的时候,同时排出大量的白色刺激性气体,主要含氯化氢、丁醇、辛醇、杂醇及增塑剂蒸气。对呼吸道有较强的
With the rapid development of China’s polymer industry, the application of plastic products is very extensive. For plastics production, especially the small and medium-sized plastic factories at the county and social levels, how to prevent occupational hazards has increasingly attracted attention. This article describes an exhaust hood used in an extruder. Due to the reasonable design of this exhaust hood, it effectively controls the harmful gases generated during the plasticization process and prevents the occurrence of occupational diseases. Chaoan Plastic Factory, mainly produces PVC plastic sandals. During the plasticization process, it is heated to 180-195°C and plasticized 2-3 times. Due to volatilization of some plasticizers and decomposition of some resins, a large amount of white irritant gas is discharged at the same time when the extruder discharges, mainly containing hydrogen chloride. , Butanol, octanol, fusel and plasticizer vapors.
