乒乓球手脚一项球类体育通顺，对球也有严格的条目，乒乓球呈圆球形，直径为40毫米，分量要在2.53~2.70克，神气呈白色或者橙色，统统来望望乒乓球是何如制造出来的。

成立材料

乒乓球的材料最初始是用一种合成纤维塑料（硝酸纤维塑料）制成，也叫赛璐珞，14年7月1日起新规初始用高分子团聚物为原料的新塑料球。

在材料厂就将原料制成直径44毫米，厚度0.8毫米的片材。

按照40%的乙醇，60%的水成立出溶液，将塑料片材放入其中，浸泡经由中让其软化，以便鄙俚均匀成型。 通过浸泡后的片材要用净水冲洗掉名义的溶液，并晾干名义的水分。

成型

领先需要用金属模具将塑料片材制形成半球形，将片材固定在模具上头，通过一边加压，一边浸入90多度的沸水中。

片材通过溶液浸泡和沸水后，将更有延展性，给模具内加压就会让片材渐渐的变成半球形。

片材制成半球型后，要用水让其快速冷却，从模具上取出后，乒乓球的一个半球就作念好了。

要通过机器将半球边际的毛边全部切削干净。

检测分类 要测量每一个半球的厚度，将不同厚度的半球进行分类，每组之间的厚度差也只消0.01毫米。

粘合

筛选后每组厚度接近的半球互相粘合在统统，将一个半球放在模具中通过加热后让边际收缩变小。

用另一个半球盖在减弱的半球上，通过机器点上胶水，胶水会跟着过错流到半球接口处。

通过机器在半球上用劲挤压，就会将两个半球统统粘合在统统，形成一个圆形的乒乓球。

加热成型 将乒乓球放入金属模具中，模具名义会有好多小孔，将其放入380度的烘箱内，让球中的空气扩展，从而让接缝处贴得更紧，也变得愈加光滑。

为了清洁掉乒乓球名义的胶水，让接缝处变得更光滑以及达到条目的分量，将乒乓球放入抛光机器中进行打磨。

检测 通过光照检测接缝是否完整，是否均匀，还要对乒乓球进行称重和旋转测试，并进行分级，高质料的用于比赛，而低质料的则用于检修。

临了在分好级的乒乓球上印上品牌和等第，这么乒乓球就制造好了。
