Quality Inspection for Construction Grade Polyvinyl Alcohol(pva) - CNPC Kunlun Paraffin Wax – Haitung
Quality Inspection for Construction Grade Polyvinyl Alcohol(pva) - CNPC Kunlun Paraffin Wax – Haitung Detail:
Paraffin waxes are separated from crude oil during the production of light(distillate) lubricating oils. These waxes are categorized by oil content and the degree of refinement. The crudest versions fall into the slack wax category and contain between 5% to 20% oil. Next on the step of refinement are scale waxes containing between 1% to 5% oil. The highest grade of refinement is the fully refined wax. Fully refined paraffin waxes contain less than 0.5% oil and have been hydro treated or clay treated to remove impurities and color. The resulting waxes are water clear, odor free, and normally food grade.
Process
This is a full refined paraffin wax product made from natural crudeased oil containing wax through the process
steps of solvent deoiling and hydrotrating.
