Physico-Chemical Characteristics and Thermal Stability of Oil Based Lubricating Fluids for Glassware Production
The investigation results about physico-chemical characteristics of I-40 and MS-20 commercial mineral oils are represented. It is shown that such oils may be the basis for the lubricating fluids used for press mold lubrication while glass containers production. Thermal stability of oils and their hydrocarbon fractions was studied. It was established that I-40 oil contains resins capable to form coke-like densification products while their burning. It is recommended to use MS-20 oil as the basis for lubricants.
