Vaseline implementation standards trait role

Vaseline is a semi-liquid mixture of alkyl hydrocarbons or saturated hydrocarbons, also known as petrolatum, which is prepared
by fractionation of petroleum.
Its state is between solid and liquid at room temperature, and has three colors
of brown, yellow and white due to different uses.
Vaseline (petroleum grease) according to the scope of use, physical and chemical properties and production requirements, the use of international common product standards divided into three categories, and in China has been added to the formulation of ordinary petroleum jelly national standards, four are: pharmaceutical petroleum jelly (GB1790-86), industrial petroleum jelly (GB6731-86), ordinary petroleum jelly (GB6732-86), capacitor petroleum jelly (GB6733-86).

。 Medical petroleum jelly: is a uniform ointment-like substance with a certain drawing property and very short brushing, odorless, which is divided into medicinal white petroleum jelly and medicinal yellow petroleum jelly according to the depth of refining, white, light yellow to light yellow, respectively; Suitable for pharmaceutical ointments, raw materials of creams and skin care ointments; It is prepared by mixing paraffin grease with mineral oil or mixing with fragrance oil and molten white paraffin or ozokic wax, which can be used to make medical ointment, in the textile industry to make emulsions, and can also be used as anti-corrosion grease for
measuring instruments and surgical instruments.
Highly refined to medicinal grade can be used as an ointment, and petrolatum-jellied for pharmaceutical use may be accompanied by other substances
.
Industrial petroleum jelly: is a solid hydrocarbon-based grease used to protect metal products; It can also be used
as a friction reduction grease under the condition that the temperature is not higher than 45°C and the load is not large.
It is suitable for anti-corrosion and anti-friction lubrication
of metal objects, metal parts and machinery.
Vaseline (petrolatum) is used in lubrication and rubber and resin formulations, when used for lubrication, it should only be filtered and refined and not treated with acid, and should not be doped with paraffin, and its melting point should be between 46-54 °C; O-grade petrolatum, which is used as a rubber softener, is a light yellow odorless semi-solid with a specific gravity of 0.
84 and a melting point of 46-48 °C
.
Ordinary petroleum jelly: divided into two types: ordinary white petroleum jelly and ordinary yellow petroleum jelly; Suitable for lubricating rubber products softener, glass fiber drawing molding emulsion, etc.
; Yellow petroleum jelly is a yellow uniform ointment, prepared by mixing spice oil with paraffin and ozokitol (yellow); It can be used in veterinary medicine and as an alternative to
medical petroleum jelly.
Capacitor Vaseline: is a white to light yellow uniform ointment; Suitable for impregnating capacitor insulation materials and depositing capacitors
