It is also used for lubrication of light machinery and precision instruments, mechanical lubrication of makeup, food industry and textile industry.

Petroleum jelly can also be used in many furniture, machinery, etc., to prevent rust, lubrication, repair cracks, etc.

Apply between two direct contact frosted glassware to prevent the glass from biting each other and becoming stuck. Most commonly, glass plugs in burets are coated with a thin layer of vaseline to increase twisting lubrication and seal gaps. To insert the glass tube into the hole of the rubber plug, apply some petroleum jelly to increase the lubrication and make the tube easier to insert.

In addition to the above, thinly applied to the camera lens may create a soft focus hazy effect.

Gịnị bụ ngwaahịa a?

Petroleum jelly is a semi-liquid mixture of alkyl hydrocarbons or saturated hydrocarbons, also called petrolatum, produced by fractional distillation of petroleum.The composition of petroleum jelly is between and, a polymer hydrocarbon obtained from petroleum fractions, and the distillation temperature is above 303 ° C. Its specific gravity is between 0.820 and 0.865, insoluble in water, but soluble in gasoline and pine oil.
