ワセリン

ワセリンは、石油の分留によって生成される、ワセリンとも呼ばれるアルキル炭化水素または飽和炭化水素の半液体混合物です。室温では固体と液体の中間の状態であり、目的に応じて茶色、黄色、白の 3 色があります。

天然ワセリンはアルキル炭化水素重油などの石油残留濃縮物から得られます。人工ワセリンは、純粋な粉砕ワックスまたはパラフィンで増粘した鉱油とパラフィングリースの混合物から得られます。ワセリンは灯油臭ではなく鉱油臭があります。医薬品や化粧品の原料として使用でき、機械の潤滑にも使用できます。

ワセリンの成分は～で、石油留分から得られる高分子炭化水素で、蒸留温度は303℃以上です。比重は0.820～0.865で、水には溶けませんが、ガソリンや松油には溶けます。

ワセリンは、石油潤滑油蒸留物を高度に精製して得られる無色、無臭、無蛍光の透明な油状液体で、滴点は約 37 ～ 54 ℃ です。添加物、水分、機械的不純物は一切含まれていません。エーテル、クロロホルム、ガソリン、ベンゼンなどの有機溶剤に溶けます。水には溶けません。化学的安定性と耐酸化性に優れ、抗酸化安定性、安定性、光安定性に優れています。

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.

We have many high-quality factories with deep cooperation, which can provide you with high quality products and competitive prices. And we can also give discounts for bulk purchases.And we cooperate with many professional freight forwarding companies, can deliver products safely and smoothly to your hands.

この商品は何ですか？

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.
