Paraffin liquid

Paraffin, Cosmetric Grade, CAS : 8012-95-1

Paraffin liquid, also known as liquid paraffin or mineral oil, has various uses in secondary schools. Here are a few common applications:

1. Science Experiments: In science laboratories, paraffin liquid is often used in experiments related to density, buoyancy, and heat transfer. It can be used to create density columns, investigate the behavior of objects in different fluids, and demonstrate convection currents.

2. Lubricant: Paraffin liquid can be used as a lubricant for certain mechanical components in school workshops or science laboratories. It can help reduce friction and ensure smooth operation of machines and equipment.

3. Preservative: Paraffin liquid can be used as a preservative for biological specimens in biology classes. It can help prevent drying out and decay of specimens, allowing them to be preserved for a longer period of time.

4. Cosmetics and Personal Care: Paraffin liquid is sometimes used in practical lessons related to cosmetics and personal care. It can be used in formulations for lip balms, lotions, creams, or other skincare products.

It's important to note that the use of paraffin liquid in secondary schools should be done under proper supervision and following safety guidelines. Teachers and students should be aware of any potential hazards associated with its use and take necessary precautions to ensure safe handling and disposal.

Paraffin liquid 液體石蠟，也稱為液體石蠟或礦物油，在中學有多種用途。 以下是一些常見的應用：

1.科學實驗：在科學實驗室中，石蠟液體常用於密度、浮力、傳熱等相關實驗。 它可用於創建密度柱、研究物體在不同流體中的行為並演示對流。

2.潤滑劑：石蠟液可用作學校車間或科學實驗室某些機械部件的潤滑劑。 它可以幫助減少摩擦並確保機器和設備的平穩運行。

3.防腐劑：石蠟液可用作生物課上生物標本的防腐劑。 它可以幫助防止標本乾燥和腐爛，從而使它們能夠保存更長時間。

4.化妝品和個人護理：石蠟液有時用於與化妝品和個人護理相關的實踐課程。 它可用於潤唇膏、乳液、乳霜或其他護膚產品的配方中。


值得注意的是，在中學使用石蠟液體應在適當的監督下並遵循安全準則。 教師和學生應了解與其使用相關的任何潛在危險，並採取必要的預防措施以確保安全處理和處置。
