鍵盤用久了又油又滑？PBT 與 ABS 鍵帽材質到底差在哪

滿心歡喜買了一把超帥的 RGB 機械鍵盤，結果每天高強度打了幾個禮拜的遊戲後，發現最常用的 W、A、S、D 鍵變得油光煥發，手放上去還會滑掉，像剛吃完炸雞沒洗手一樣？

這在鍵盤圈被稱為「打油」。罪魁禍首通常不是你的手汗，而是鍵帽的「材質」。

1. ABS 鍵帽：原廠的最愛，打油的元兇

市面上 80% 的原廠鍵盤（即使是幾千塊的大廠牌）都配備 ABS 鍵帽。為什麼？因為它好加工。

優點： 顏色可以做得很鮮豔，RGB 透光效果極佳，剛買來的時候手感很細膩滑順。
缺點： 硬度很低。只要你的手指每天摩擦，不出一個月，表面的微小紋路就會被磨平，變成反光又滑溜溜的「打油」狀態。

2. PBT 鍵帽：硬派玩家的救贖

如果你受夠了黏膩的手感，請去買一套 PBT 鍵帽換上。這是一種硬度極高的塑料。

優點： 表面有一種像細沙一樣的「磨砂感」，非常乾爽。重點是：超級耐磨，幾乎永遠不會打油。
缺點： 加工困難，所以價格通常較貴。而且因為材質特性，如果要做成字體透光的款式，邊緣有時候會有一點不夠銳利。

💡 換鍵帽就像換新鍵盤

老玩家都知道，別被原廠鍵帽綁死。花個幾百塊買一套好看的 PBT 鍵帽自己拔插換上，不但手感煥然一新，爽度完全不輸買一把新鍵盤。

換完鍵帽，記得測試！

在拔鍵帽的過程中，有時候會不小心把下面的機械軸體弄鬆。換完記得全按一遍檢查看看。

Shiny and Slippery Keys? PBT vs. ABS Keycaps Explained

You bought a sick new RGB mechanical keyboard, but after a few weeks of intense gaming, the W, A, S, and D keys look incredibly shiny and feel greasy, like you've been eating fried chicken while playing?

In the keyboard community, this is called "Shine." And the culprit usually isn't your sweaty hands; it's the "material" of the keycaps.

1. ABS Keycaps: The Default Choice, The Shine Culprit

About 80% of pre-built keyboards (even expensive flagship models) come with ABS keycaps. Why? Because it's cheap and easy to mold.

Pros: Vibrant colors, excellent RGB backlight transparency, and a smooth, refined feel right out of the box.
Cons: Low hardness. With daily friction from your fingers, the micro-texture on the surface wears completely flat in under a month, creating that glossy, slippery "shine."

2. PBT Keycaps: The Hardcore Gamer's Salvation

If you're sick of the greasy feel, buy a set of PBT keycaps. It's a much harder, more durable plastic.

Pros: It has a satisfying, dry, slightly "sandy" texture. The best part? It's incredibly wear-resistant and practically never shines.
Cons: Harder to manufacture, making it more expensive. Also, getting perfect transparent shine-through lettering is difficult with this material.

💡 Swapping Keycaps = A New Keyboard

Veterans know you don't have to stick with stock keycaps. Spending a few bucks on a fresh set of PBT keycaps can completely transform the feel and look of your board, making it feel brand new.

Check your keys after swapping!

Sometimes pulling off keycaps can accidentally loosen the mechanical switches underneath. Make sure to test every key.
