AI Technical Summary

Technical Problem

There is a lack of systematic methods in the prior art to identify and isolate the types of hydrotalcites in calcium-zinc stabilizers, resulting in strong empirical and fuzzy identification process.

Method used

By dissolving calcium -zinc stabilizers samples with mixed solvents of second metalia and cycloidone, heating and centrifugal treatment, collecting sediments, and Fourier transformed infrared spectrum (FTIR), X -ray diffraction (XRD), and Synchronous thermal analysis (STA) test to identify the existence and type of water talc.

Benefits of technology

The systematic separation and identification of water talcium in calcium zinc stabilizers can be achieved, and it can accurately determine whether there are slippery stones in the stabilizer, and determine its type to improve the appraisal efficiency and accuracy.

Abstract

The present invention belongs to the field of chemical separation and identification, and specifically relates to a method for separating and identifying hydrotalcite in a stabilizer. The present invention obtains a pure precipitate sample (if hydrotalcite exists, the precipitate is a hydrotalcite with a high purity) by separation and treatment from an original calcium zinc stabilizer sample, and can successfully determine whether hydrotalcite exists in the stabilizer and identify the specific type of hydrotalcite in the stabilizer by methods such as FTIR, XRD, and STA. The present invention solves the problems of empiricism and ambiguity in the identification of hydrotalcite in the stabilizer.
