割膠是指從橡膠樹上收集膠乳的一個過程。首先在樹上劃一道口子，挖通膠乳的管道，這樣膠乳就能流動。 割膠對環境的影響很大。
過程[編輯]
膠農必須要每個晚上都清除掉 Each night a rubber tapper must remove a thin layer of bark along a downward half spiral on the tree trunk. If done carefully and with skill, this tapping panel will yield latex for up to five years. Then the opposite side will be tapped, allowing this side to heal over. The spiral allows the latex to run down to a collecting cup. The work is done at night or in the early morning before the day's temperature rises,[1] so the latex will drip longer before coagulating and sealing the cut. 割膠工每個晚上都必須在樹幹上按照螺旋形狀割去一層樹皮。如果這一工序是小心而且有技術的完成，那麼膠樹將能連續至少5年以上產出乳膠。然後反面再被割膠，以便讓原先那一面得到恢復。螺旋狀使得膠乳流入一個杯子。這些工作通常是在晚上或者凌晨完成，必須要在氣溫上升之前完成。
Depending on the final product, additional chemicals can be added to the latex cup to preserve the latex longer. Ammonia solution helps prevent natural coagulation and allows the latex to remain in its liquid state. Plastic bags containing a coagulant have replaced cups in many plantations in Malaysia. This form of latex is used as the raw material for latex concentrate, which is used for dipped rubber products or for the manufacture of ribbed smoke sheet grades. 根據形成的最終產品的不同，膠乳裡面會添加不同的化學助劑以是的膠乳可以保存得更加長久。氨水可以使得
信息技術[編輯]
在信息技術當中，『割膠』一詞通常被用作有計劃的工作部署的諷刺說法。這是由於工作部署的時間點是非常關鍵的。工作部署通常在夜間，客戶活動非常少的時候完成。
