Description
技术领域Technical Field
本发明涉及环境污染的模拟检测领域，特别涉及一种模拟塑料制品有害物质释放和实时收集的装置及方法。The present invention relates to the field of simulation detection of environmental pollution, and in particular to a device and method for simulating the release and real-time collection of harmful substances from plastic products.
背景技术Background Art
近年来塑料产品的使用规模逐年递增几乎覆盖人类生活的各个领域。塑料制品作为高分子材料其生产过程中添加的塑化剂、阻燃剂、抗氧化剂等助剂多达数百种之多，这些助剂绝大多数都以被证实会直接威胁环境健康。在食品安全和医药卫生等领域塑料制品有害物质的释放已经被纳入政府监管体系并且有对应的检测方法和模拟装置。在环境监测领域塑料制品释放有害物质的检测和风险评估处于起步阶段但是已经收到广泛关注。In recent years, the use of plastic products has increased year by year, covering almost every field of human life. As a polymer material, hundreds of additives such as plasticizers, flame retardants, and antioxidants are added to the production process of plastic products. Most of these additives have been proven to directly threaten environmental health. In the fields of food safety and medical health, the release of harmful substances from plastic products has been included in the government regulatory system and has corresponding detection methods and simulation devices. In the field of environmental monitoring, the detection and risk assessment of harmful substances released from plastic products is in its infancy but has received widespread attention.
由于环境条件模拟和食品药品存储条件模拟差异较大，较为成熟的相关模拟装置和采集方式均达不到模拟环境条件的预期。主要原因有以下两点：第一，环境因素复杂多样。塑料制品在环境中的暴露周期长所以要求模拟释放装置要尽可能模拟实际环境因素，同时要具有加速塑料老化的能力以此来评估长期暴露于环境中的塑料制品释放有害物质的动态变化情况。第二，释放有害物质的收集方式无法通用。加速塑料老化的模拟释放方式往往伴随着高温度、高光强等极端气候条件。传统的累积采集方式目的是在反应区域累积固定释放有害物质，这会导致释放出的有害物质长时间停留在模拟环境中由此带来的转化、分解无法避免。因此既能满足多种类的环境因素模拟又可以有效避免释放有害物质的转化分解的模拟和采集装置，仍属于该检测领域的空白，亟需填补。Due to the large differences between environmental condition simulation and food and drug storage condition simulation, the more mature related simulation devices and collection methods cannot meet the expectations of simulated environmental conditions. The main reasons are as follows: First, environmental factors are complex and diverse. Plastic products have a long exposure period in the environment, so the simulation release device is required to simulate the actual environmental factors as much as possible, and at the same time have the ability to accelerate plastic aging in order to evaluate the dynamic changes of harmful substances released by plastic products exposed to the environment for a long time. Second, the collection method of releasing harmful substances cannot be universal. The simulated release method that accelerates plastic aging is often accompanied by extreme climatic conditions such as high temperature and high light intensity. The purpose of the traditional cumulative collection method is to accumulate and fix the release of harmful substances in the reaction area, which will cause the released harmful substances to stay in the simulated environment for a long time, and the resulting transformation and decomposition cannot be avoided. Therefore, simulation and collection devices that can not only meet the simulation of various types of environmental factors but also effectively avoid the transformation and decomposition of the release of harmful substances are still blank in this detection field and need to be filled urgently.
