皮革和毛皮甲醛含量检测技术与控制要点研究

Techniques for Detecting and Controlling Formaldehyde Content in Leather and Fur

为了深入研究皮革和毛皮中甲醛含量的检测技术与关键控制点,文章运用文献资料法对甲醛的来源以及当前主流的检测手段进行了系统性的梳理与分析。通过严谨的试验分析,探讨了不同试验条件对检测结果的影响。研究结果表明,萃取温度和萃取时间是影响甲醛含量测定准确性的两大核心因素,对结果偏差的贡献最为显著。因此,在进行皮革和毛皮甲醛含量检测时,必须严格控制萃取条件,确保萃取液预热至40℃,并在(40±1)℃的恒温水浴中进行萃取。同时,振荡器的振荡频率应维持在(50±10)次/min,萃取时间精确控制在(60±2)min,以保证检测结果的准确性和可靠性。

In order to delve deeply into the detection techniques and critical control points for formaldehyde content in leather and fur,the article systematically examines and analyzes the origins of formaldehyde and the current mainstream detection methods using a literature review approach.Through rigorous experimental analysis,the impact of different experimental conditions on detection results is discussed.The research findings indicate that extraction temperature and extraction time are the two core factors affecting the accuracy of formaldehyde content determination,with their contribution to result deviation being most significant.Therefore,in the process of detecting formaldehyde content in leather and fur,it is imperative to strictly control the extraction conditions,ensuring that the extraction solution is preheated to 40℃and extraction is conducted in a constant temperature water bath at(40±1)℃.Additionally,the oscillation frequency of the oscillator should be maintained at(50±10)times/min,and the extraction time precisely controlled at(60±2)min,to ensure the accuracy and reliability of the detection results.
