Quantitative analysis method for FTIR spectrum of each component of ABS material mixture

Abstract

The invention belongs to the technical field of material analysis of automobile parts and provides a quantitative analysis method for FTIR spectrum of each component of an ABS material mixture, comprising the following steps: obtaining an FTIR spectrum of a to-be-measured mixture, respectively providing the FTIR spectrums of standard substances and analyzing the FTIR spectrum of the to-be-measuredmixture to respectively obtain coordinate groups of the to-be-measured mixture and various standard substances in a multidimensional space; and introducing the coordinate groups of the to-be-measuredmixture and various standard substances into the following equation set. The method in the invention has the following advantages that through the analysis method, the mixture composed of any two ormore substances having the FTIR spectrums is quantitatively analyzed, the mass percentage of the to-be-measured substance can be measured quickly and accurately, the coordinate group in the multidimensional space is introduced into the equation set to solve the mass percentage of various standard substances in the to-be-measured mixture, and an important analysis control means is provided in material anatomy and quality monitoring.

Description

technical field [0001] The invention belongs to the technical field of auto parts material analysis, relates to an ABS material, in particular to an FTIR spectral quantitative analysis method for each component of an ABS material mixture. Background technique [0002] At present, the modified ABS (acrylonitrile, butadiene, styrene) copolymer is a kind of high strength, good toughness, and excellent processing performance, which is widely used in industries such as automobile parts, electronic appliances, and building materials. For large-scale enterprises, whether in product quality control or unknown sample analysis, how to quickly and accurately quantitatively analyze the ABS mixture has become an important issue. At present, titration is the most commonly used analysis method for quantitative analysis of materials. It uses a reagent solution (standard solution) whose exact concentration is known. However, due to its long reaction time, the test sample will be damaged due ...

At present, titration is the most commonly used analysis method for quantitative analysis of materials. It uses a reagent solution (standard solution) whose exact concentration is known. However, due to its long reaction time, the test sample will be damaged due to the sampling process. Therefore, it is impossible to accurately analyze the content of the sample components.
