Cell phone protective film on the small label to tear off the top, as well as how to remove plastic glue?

Don't eraser, this will make the screen of mobile phone very wear off. You go to buy a mobile cleaner, and then quickly wipe with the eye wipe gently wipe it
The physical properties of ethanol are mainly related to the properties of low carbon straight chain alcohols. The hydroxyl radical in the molecule can form hydrogen bonds, so the viscosity of the alcohol is large, and the organic compounds with similar molecular weight are not so great
Ethanol is also used as a solvent in the reaction, so that both the organic and inorganic substances in the reaction can dissolve, increase the contact area and increase the reaction rate. For example, in the saponification reaction of oils and fats, the addition of ethanol can dissolve NaOH and dissolve oil, so that they can contact fully in the homogeneous phase (the solution of the same solvent) and accelerate the reaction rate.
