凡士林

凡士林是烷基烴或飽和烴的半液體混合物，也稱為凡士林，由石油分餾生產。常溫下其狀態介於固體和液體之間，有棕色、黃色、白色三種顏色，用於不同的用途。

天然凡士林源自石油殘渣濃縮物，例如烷基烴重油。人造凡士林是由純地蠟或石蠟稠化的礦物油和石蠟油脂的混合物製成的。凡士林具有礦物油氣味，而不是煤油氣味。可用作藥品、化妝品的原料，也可用於機器潤滑。

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.

這個產品是什麼？

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.
