Application of Different Analytical Methods Used in the Study of the Cross-linking of Resins in Intermediate- Product Used in Manufacturing of Abrasive Articles

摘要

Determining the degree of the crosslinking of resins in intermediate-product used in the manufacturing of abrasive articles is difficult and complicated because of the presence of different components in the material. The abrasive articles consist of abrasive (e.g., fused alumina), filler (e.g., potassium fluoroborate_KBF4, pyrite_FeS2), wetting agent (e.g., resol), and binder (e.g., novolak). Proper hardening of intermediate-product is a very important stage during production of abrasive tools. The hardening process depends on crosslinking of resins. Following were used to study crosslinking of resins: IGC, washing away method, NMR broad line, DSC, and FTIR methods.
