A cross-linker may be defined as a molecule having at least two reactive groups and engages into a chemical reaction, which forms a bridged structure among the polymer chains. Crosslinkers consist of a mixture of salts and guar gel slurry to provide viscosity used for proppant transport in stimulation applications or cleaning treatments in pipelines.
Various combination Substance Classification and Function
Cross-linker is the chemical used to create a cross-linked fluid system. When cross-linker is combined with a 20–30 lb linear gel system, cross-linked fluid is created.
