凡士林

凡士林是石油经分馏而制成的一种半液态烷基碳氢化合物或饱和碳氢化合物混合物，又称矿脂，常温下状态介于固态与液态之间，有棕、黄、白三种颜色，以适应不同用途。

天然凡士林是由烷基烃重油等石油残渣浓缩物制成的。人造凡士林是由纯磨制蜡或石蜡稠化的矿物油与石蜡脂的混合物制成的。凡士林有矿物油气味，不是煤油气味。可用作药物和化妆品的原料，也可用于机器润滑。

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.

凡士林是由石油润滑油馏分深度精制而得的一种无色、无臭、无荧光的透明油状液体，滴点约37-54摄氏度。不含任何添加剂、水分和机械杂质。溶于乙醚、氯仿、汽油和苯等有机溶剂。不溶于水。有良好的化学稳定性和抗氧化性，具有良好的抗氧化稳定性、安定性和光稳定性。

Vaseline can be used for medical purposes: Vaseline is primarily a chemically inert hydrocarbon and has no bactericidal power; But it is not hydrophilic, will not be absorbed, smeared on the skin can form a film on its surface, so that water is not easy to evaporate and lose, can keep the skin moist, block bacteria from the air and skin contact, thereby reducing the possibility of infection.

In addition to being used as infiltrating and filling capacitors, Vaseline can be used as rust and water repellent. When making waterproof film, it will produce a waterproof film after repeated coating 2-3 times after drying.

Electricians apply Vaseline between the cable and the junction box to lubricate it.

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.

这是什么产品？

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.
