This invention discloses a quality testing method for refined PLAH composite plasticizers. By integrating Raman spectroscopy-attenuated total reflectance infrared dual-spectral fusion, simultaneous thermorheological characterization, accelerated migration micro-model testing, and a multi-dimensional index model, this method overcomes the shortcomings of existing technologies that only detect chemical content, cannot reflect functional performance, and lack rapid evaluation capabilities. This method achieves integrated and rapid detection of molecular structure matching, phase stability, migration risk, and long-term performance of refined PLAH composite plasticizers, with a total testing cycle of ≤8 hours and a correlation between the test results and actual application performance ≥0.92. This method requires no complex pretreatment and combines the advantages of both destructive and non-destructive testing, making it suitable for online quality control in industrial production, warehousing acceptance, and application performance prediction. It provides key technical support for the optimization of the refining process and quality control of composite plasticizers for bio-based polylactic acid (PLA) materials.

This invention relates to the field of thermal spraying technology, and more particularly to a method for spraying a high-strength cermet undercoat onto a metal roller substrate. The method determines the initial spraying process and parameters based on the chemical content, length, diameter, and oxide film thickness obtained from testing the metal roller substrate, and performs pre-spraying to generate a pre-coating layer. Based on the unmelted particle area ratio and interface stiffness in the pre-coating layer, it determines whether to adjust the initial parameters, the corresponding adjustment amount, and the transition spraying process to generate a transition coating. Based on the transition coating, it determines the bonding strength, cohesive strength, and microcrack density. Based on the bonding strength and cohesive strength, it calculates the coating quality index and determines whether repair adjustments are needed. Based on the microcrack density, it determines the adjustment amount of the repair adjustment parameters. This invention significantly improves the anti-stripping performance and long-term stability of the cermet undercoat by online detection, adjustment, and correction of spraying quality parameters during the spraying process.
