在通過式清洗機的眾多部件中，內膽堪稱關鍵 “角色”，它如同清洗機的 “心臟”，不僅關乎清洗效果，更對設備的耐用性與安全性有著深遠影響。內膽材質多種多樣，每種都有獨特 “性格”，適配不同應用場景。

　　Among the numerous components of a through type cleaning machine, the inner liner can be considered a key "role". It is like the "heart" of the cleaning machine, not only related to the cleaning effect, but also has a profound impact on the durability and safety of the equipment. There are various types of inner liner materials, each with a unique "personality" that is suitable for different application scenarios.

　　不銹鋼：清洗機內膽的 “中流砥柱”

　　Stainless steel: the "backbone" of the cleaning machine liner

　　不銹鋼家族在清洗機內膽材質中占據主導地位，其中 304 和 316 型號最為常見。以 304 不銹鋼來說，它具備良好的耐腐蝕性，能從容應對大多數清洗環境，普通工業清洗場景中，其耐腐蝕特性確保內膽在長期使用中不會輕易被侵蝕，穩定性極佳。同時，304 不銹鋼還擁有不錯的耐熱性，在一些需要高溫輔助清洗的工藝里，也能保持穩定性能，不發生變形等問題。在食品加工行業的通過式清洗機中，304 不銹鋼內膽憑借無毒無害、易清潔的優點，保障了食品接觸的安全衛生，且日常清洗維護輕松便捷，表面光滑不易殘留污垢。

　　The stainless steel family dominates in the material of cleaning machine liners, with 304 and 316 models being the most common. For example, 304 stainless steel has good corrosion resistance and can easily handle most cleaning environments. In ordinary industrial cleaning scenarios, its corrosion resistance ensures that the inner liner will not be easily corroded during long-term use and has excellent stability. Meanwhile, 304 stainless steel also has good heat resistance and can maintain stable performance without deformation in some processes that require high-temperature assisted cleaning. In the through type cleaning machine of the food processing industry, the 304 stainless steel liner ensures the safety and hygiene of food contact due to its non-toxic, harmless, and easy to clean advantages. Daily cleaning and maintenance are easy and convenient, and the surface is smooth and not prone to residual dirt.

　　而 316 不銹鋼則更勝一籌，它在耐氯離子腐蝕方面表現卓越。在有鹽水或海水參與清洗的工業環境，如海洋設備清洗、部分化工產品清洗等場景中，316 不銹鋼內膽能有效抵御氯離子的侵蝕，大大延長設備使用壽命，減少因腐蝕導致的頻繁更換內膽的成本與麻煩。

　　316 stainless steel is superior in terms of resistance to chloride ion corrosion. In industrial environments where saltwater or seawater is involved in cleaning, such as cleaning marine equipment and some chemical products, 316 stainless steel liners can effectively resist the erosion of chloride ions, greatly extending the service life of equipment and reducing the cost and trouble of frequent replacement of liners due to corrosion.

　　塑料：應對特殊清洗需求的 “多面手”

　　Plastic: A versatile solution for special cleaning needs

　　塑料材質的內膽在特定領域也有出色表現。像聚丙烯（PP），具有良好的耐熱性和化學穩定性，面對一些對金屬材質有腐蝕性的化學物質清洗任務時，PP 內膽能發揮優勢。在電子元件清洗中，部分電子元件可能會與金屬發生化學反應，此時 PP 材質內膽的通過式清洗機就能安全清洗，避免元件受損。

　　Plastic inner liners also perform well in specific fields. Like polypropylene (PP), it has good heat resistance and chemical stability. When faced with cleaning tasks that are corrosive to metal materials, PP liner can play an advantage. In the cleaning of electronic components, some electronic components may undergo chemical reactions with metals. In this case, the PP material inner liner can be safely cleaned using a through type cleaning machine to avoid component damage.

　　聚四氟乙烯（PTFE）材質內膽同樣不可小覷，它以極低的摩擦系數和超強的耐腐蝕性著稱。雖然成本相對較高，但在一些高端精密儀器清洗、特殊化工產品清洗等對材質要求極高的場景下，PTFE 內膽能提供可靠保障，確保清洗過程不會對被清洗物品造成絲毫損傷，同時自身能耐受各種強酸強堿等極端化學環境。

　　The inner liner made of polytetrafluoroethylene (PTFE) material should not be underestimated, as it is known for its extremely low friction coefficient and super strong corrosion resistance. Although the cost is relatively high, in some high-end precision instrument cleaning, special chemical product cleaning and other scenarios with extremely high material requirements, PTFE liner can provide reliable guarantee, ensuring that the cleaning process will not cause any damage to the cleaned items, and at the same time, it can withstand various extreme chemical environments such as strong acids and alkalis.

　　陶瓷：耐高溫強腐蝕場景的 “首選”

　　Ceramics: the "first choice" for high temperature and strong corrosion resistance scenarios

　　陶瓷材質內膽憑借耐高溫和耐腐蝕性的突出特點，在特定清洗場景中占據重要地位。當清洗工作涉及高溫溶液，如某些金屬加工行業中需清洗高溫處理后的工件，或者清洗含有強酸堿溶液的物品時，陶瓷內膽能穩定應對。在高溫環境下，陶瓷內膽不會像部分金屬或塑料材質那樣發生變形、軟化等問題；面對強酸堿侵蝕，也能保持結構完整，維持良好的清洗工作狀態，保證清洗機在惡劣條件下長期穩定運行。

　　Ceramic material inner liners play an important role in specific cleaning scenarios due to their outstanding characteristics of high temperature resistance and corrosion resistance. When cleaning work involves high-temperature solutions, such as cleaning workpieces that have undergone high-temperature treatment in certain metal processing industries, or cleaning items containing strong acidic and alkaline solutions, ceramic liners can stably cope. In high temperature environments, ceramic inner liners will not deform or soften like some metal or plastic materials; In the face of strong acid-base erosion, it can also maintain structural integrity, maintain good cleaning working conditions, and ensure long-term stable operation of the cleaning machine under harsh conditions.

　　碳鋼：簡單清洗場景的 “經濟之選”

　　Carbon Steel: The 'Economic Choice' for Simple Cleaning Scenarios

　　碳鋼材質成本較低，在對腐蝕性要求不高的簡單清洗應用中能發揮作用。例如，在一些對清洗精度、材質耐腐蝕要求不高的粗加工行業，如普通建筑材料表面簡單污垢清洗等場景下，使用碳鋼內膽的通過式清洗機可滿足基本清洗需求，且能有效控制設備成本投入，為企業帶來一定的經濟效益。不過，由于碳鋼耐腐蝕性較差，在濕度較大或有腐蝕性物質的環境中易生銹，所以適用場景相對受限。

　　Carbon steel material has a lower cost and can play a role in simple cleaning applications that do not require high corrosiveness. For example, in some rough machining industries that do not require high cleaning accuracy and material corrosion resistance, such as simple dirt cleaning on the surface of ordinary building materials, the use of a through type cleaning machine with a carbon steel liner can meet basic cleaning needs and effectively control equipment cost investment, bringing certain economic benefits to the enterprise. However, due to the poor corrosion resistance of carbon steel, it is prone to rusting in environments with high humidity or corrosive substances, so its applicability is relatively limited.
