Mechanism of decoagulant

A depressant is a chemically synthesized polymer or condensate that generally contains polar groups (or aromatic nuclei) and alkyl chains similar in structure to paraffin hydrocarbons. Point depressant can not prevent paraffin from crystallizing out at low temperatures, that is, the turbidity point of the oil is unchanged, it is through the adsorption on the surface of the wax crystal or with the wax eutectic to change the shape and size of the wax crystal, prevent the wax from forming a three-dimensional network structure, so that it still maintains the flow ability of the oil at low temperatures. It should be emphasized that the coagulant can only take off and fall in the oil containing a small amount of wax, and the oil does not contain wax or contains too much wax. The most commonly used depressant is methyl dimethacrylate.
