Full-Chain Quality Control and Stability Improvement Solution for Raw Materials

The quality stability of chemical raw materials directly affects the performance of downstream products. This solution builds a quality control system of “full-process testing + intelligent tracing + continuous improvement”. In the procurement link, it conducts full-index incoming inspection on raw materials provided by suppliers, including purity analysis, component content determination, physical and chemical property testing (such as temperature resistance, acid and alkali resistance, viscosity, etc.) and impurity content testing (such as heavy metals, harmful organic substances). High-precision equipment such as high-performance liquid chromatography and infrared spectrometers are adopted to ensure that raw materials meet procurement standards. Meanwhile, a supplier quality rating system is established to regularly evaluate the quality stability of suppliers’ products and optimize the supplier structure. In the production link, quality inspection points are set at key process nodes to monitor component changes, temperature, pressure and other parameters during the reaction process in real time, adjust processes in a timely manner and avoid the production of unqualified products. Automated sampling and testing equipment are used to reduce manual operation errors and improve testing efficiency. In the delivery link, batch sampling inspection is carried out on finished products, and detailed quality inspection reports are issued to ensure consistent performance of each batch of products. Meanwhile, a product quality tracing system is established to record raw material procurement batches, production process parameters, testing results and other information, realizing full traceability “from raw materials to finished products”. If quality problems occur, the causes can be quickly located and recall processing can be carried out. In addition, the solution includes quality problem rectification services, providing rectification suggestions such as process optimization and raw material replacement for problems found in testing (such as substandard purity and excessive impurities), helping enterprises improve product quality stability and reduce customer complaint rates.
