Indoor Particle Contamination in Airlaid Papermaking Workshop

一现场基于八地点的空气采样测试在天津在 anairlaid papermak-ing 专题讨论会被执行，中国。由理论计算，在室内的静态的气流的超级吸收剂聚合物(树液) 尺寸和它的存在国家被获得。在取样的空中的树液内容通过化学分析方法被测试并且发现了是人，健康在生产区域限制的 3.0-7.2 时间。推迟粒子(TSP ) 和能呼吸的粒子的总数的集中被称完成。大多数担心的粒子为改变的功能区域不同。比 10 亩 m 小的粒子主要在主要生产过程，和在包装区域产生的 73%-90 百分比粒子被生产比 10 亩大 m。树液原料粒子罐头容易改变了到由不可避免的挤出和摩擦推迟形式。在能呼吸的粒子和 TSP 之间的关联在大气的环境与那同意很好。

An onsite testing based on eight-site air sampling was carried out in an airlaid papermaking workshop in Tianjin, China. By theoretical calculation, super absorbent polymer （SAP） size and its existent state in indoor static airflow were obtained. SAP content in the sampled air was tested through chemical analysis method and found to be 3.0-7.2 times that of the human health limit in production areas. The concentrations of total suspending particles （TSP） and respirable particles were achieved by weighing. Particles of the most concern differ for varied function areas. Particles smaller than 10μm are mostly produced in the main production process, and 73%-90% particles generated in packing areas are larger than 10μm. SAP raw material particles can easily changed to suspending form by inevitable extrusion and frication. Correlation between respirable particles and TSP agrees well with that in atmospheric environment.
