为什么手机屏幕摸起来如此顺滑——大猩猩玻璃的科学原理

Most modern phone screens use chemically strengthened glass called Gorilla Glass.
Engineers dip ordinary glass into a hot potassium salt bath for several hours.
Smaller sodium ions in the glass surface get replaced by larger potassium ions.
This creates compressive stress that makes the surface much harder to scratch.
The process also prevents tiny surface cracks from spreading easily under pressure.
Unlike plastic coatings, this strengthening happens throughout a thin outer layer.
Each new generation improves resistance to drops, abrasion, and even oil stains.
Manufacturers test durability by dropping phones onto rough concrete from increasing heights.
Because it’s transparent and tough, Gorilla Glass enables thinner, lighter, and more responsive touchscreens.
Its invention shows how materials science solves real-world problems without users noticing.

Most modern phone screens use chemically strengthened glass called Gorilla Glass. 大多数现代手机屏幕采用一种名为‘大猩猩玻璃’的化学强化玻璃。
Unlike plastic coatings, this strengthening happens throughout a thin outer layer. 与塑料涂层不同，这种强化作用遍及一层薄薄的外层。
This creates compressive stress that makes the surface much harder to scratch. 这会在表面形成压应力，使其更耐刮擦。
