以聚酯HMA(热熔胶)、聚烯烃HMA和聚酰胺HMA为研究对象,建立了HMA熔融黏度的可编程控制式黏度计连续检测法,并对其进行了多种试验条件的对比试验和验证试验。研究结果表明:与传统检测方法相比,可编程控制式黏度计连续检测法具有(同等检测时间)多数据采集之优点,既可实现多温度、多时间点高密集数据采集,又可自动显示熔融黏度变化曲线;熔融黏度-时温曲线的综合分析结果,对新产品改性研制具有良好的指导作用。
Taking HMA (hot melt adhesive), polyolefin (HMA) and polyamide (HMA) as the research objects, a continuous and controlled method of viscometer with HMA melt viscosity was established and compared with various test conditions. Verification test. The results show that the programmable viscometer continuous detection method has the advantages of multiple data acquisition (same detection time) compared with the traditional detection methods, which can not only realize the multi-temperature, multi-time high-density data acquisition, but also automatically display Melt viscosity curve; melt viscosity - temperature curve of the results of a comprehensive analysis of new product development has a good guide.
