Will aluminum react with 100-degree boiling water? Why will it explode?
Under normal circumstances, the reaction of aluminum with boiling water of 100 degrees was relatively weak. However, in processes such as aluminum processing (deep well casting), when a large amount of high-temperature molten aluminum (the temperature is much higher than 100 degrees, usually between seven or eight hundred degrees) comes into contact with water, it will explode, mainly including physical and chemical processes.
From a physical point of view, due to the huge temperature difference and the boiling point of water being much lower than the temperature of molten aluminum, when molten aluminum came into contact with water, the water temperature would quickly reach the boiling point and enter a state of superheating. The water would instantly evaporate into gas, and the volume would expand by more than 1000 times. In a relatively closed space (such as a narrow space in a casting well), steam would instantly evaporate to produce pressure waves, releasing shock waves, mechanical energy, light energy, sound energy, and other forms of energy, causing an explosion. However, the power of this physical explosion was relatively small.
In terms of chemical processes, aluminum was a metal element with a very active chemical reaction. When a large amount of high-temperature molten aluminum (such as in the processing process) came into contact with water, a chemical reaction would occur. The reaction equation was 2AI +6H ^O = 2AI (Ox)+3H ^. This process would release a huge amount of energy, causing serious explosion damage.

Does offset printing reflect light? Why doesn't it stick to paper?
Not all offset printing is reflective. For example, the metallic luster offset printing effect achieved by heating the imprinted silver foil had a reflective effect. This technology could bring a unique reflective effect to the printed matter, making it more noble and luxurious.
In the case of offset printing non-stick paper, after applying a layer of silicon oil on the paper, it would not be able to bond with the hot melt glue. These papers that had been treated with silicon oil were like insulated hot melt glue. No matter how hard they pressed, they could not stick to the hot melt glue because the silicon oil had an isolating effect.
