<p>智能手機現在越做越精致,質量越來越好,不過價格也是越來越高,新款手機更是要掏出自己省吃儉用的幾千大洋才能買到。所以保護好我們珍貴的手機是很件重要的事情。市面上<a href="https://www.ow.com.tw/">手機殼</a>數不勝數,大體分爲兩種,硬殼和軟殼。</p> <p>那麽這兩種不同材質的矽膠殼我們應該如何選擇呢?</p> <p><img src="https://www.ow.com.tw/wp-content/uploads/2023/09/硅膠手機殼.webp" width="800" height="502" /></p> <p>首先來了解一下<a href="https://www.ow.com.tw/silicone-case">矽膠手機殼</a>的優點。它比較突出的優點就是防摔,因爲矽膠制品本身具有一定的彈性,在手機落地的時候能起到緩沖作用。還有矽膠無毒無味,不會産生有害物質,不會對人體造成傷害。<a href="https://www.ow.com.tw/silicone-case">液態矽膠手機殼</a>的使用壽命長,矽膠耐磨,耐氧化,正常使用可以用很久。</p> <p>它的缺點也比較明顯,就是太厚,易髒,不易散熱,矽膠殼做的太薄起不到緩沖作用。易髒是因爲矽膠有一定的吸附性,灰塵汗漬都容易附著在上面。矽膠耐熱性好,但是導熱性不強,手機長時間工作,熱量不容易散發。</p> <p>硬殼的<a href="https://www.ow.com.tw/">手機保護殼</a>一般材質是用的PC工程塑料。它的優點是價格便宜,質量輕,保護殼的厚度較薄,防摔性能也很不錯,而且散熱性好于矽膠保護套。</p> <p>缺點是使用壽命不如矽膠保護套。</p>
