Basic information
1859, the inventor RobertChesebrough first extracted vaseline from petroleum. Its original name was "petroleumjelly", in which "Petroleum" was petroleum and "jelly" was a gelatinous substance, which was later named vaseline ['v? Gigi Lai: n]), and said in the American patent book of the product: "I, Robert Chesenberg, invented a brand-new and very helpful product from petrochemical industry, named Vaseline."
This word comes from the combination of the German word "wasser" and the Greek word "elaeon".
Vaseline is a transliteration of vaseline, which is an oily petroleum product. Mineral oil smell is allowed from white to yellow brown, but kerosene smell is not allowed. The impact point is about 37-54 degrees. It is refined from petroleum residue with sulfuric acid and clay, and can also be prepared from solid paraffin and mineral lubricating oil. Chemical composition of vaseline: long-chain alkanes.
The scientific name of vaseline is petrolatum. Its main raw material is wax paste extracted from the residual oil after atmospheric and vacuum distillation of crude oil. At the same time, it is necessary to mix different amounts of high and medium viscosity lubricating oil as needed. The yellow wax paste extracted from petroleum residue contains many impurities, which are not allowed to contain any substances harmful to human body or have peculiar smell, whether for medicinal or cosmetic purposes, and can only be used after deep refining and full removal. According to different requirements, it can be divided into ordinary vaseline, medical vaseline, cosmetic vaseline, industrial vaseline and capacitor vaseline.
Besides being used as lubricant, insulating agent, cosmetic, ointment, wetting and filling capacitor, it can also be used as antirust agent and waterproof agent. When making waterproof membrane, it is suggested to mix vaseline and tung oil and smear it on the surface of the object that needs waterproof. After drying, it is repeatedly brushed for 2-3 times to form a waterproof film.
