Decoating is a process in surface engineering in which existing coatings, paints or layers are removed from the surface of a substrate or workpiece. This process is often necessary to prepare the surface for recoating, repair, or some other form of surface treatment.脫涂層是表面工程中的一種過(guò)程，其中從基材或工件的表面去除現(xiàn)有的涂層、油漆或?qū)印＿@個(gè)過(guò)程通常是準(zhǔn)備表面進(jìn)行重涂、修復(fù)或其他形式的表面處理所必需的。

There are several reasons why stripping may be necessary:需要?jiǎng)冸x涂層的原因有多種：

1. Preparation for recoating: when an existing coating or paint is damaged, obsolete, or no longer functional, it must be removed before a new coating can be applied.重涂準(zhǔn)備：當(dāng)現(xiàn)有涂層或油漆損壞、過(guò)時(shí)或不再有效時(shí)，必須先將其去除，然后才能應(yīng)用新的涂層。

2. Repair: coatings that are damaged may need to be removed so repairs can be made to the underlying surface.修復(fù)：可能需要去除損壞的涂層，以便對(duì)底層表面進(jìn)行修復(fù)。

3. Quality Control: In some cases, removal of coatings is necessary to verify or test the quality or integrity of the substrate.質(zhì)量控制： 在某些情況下，需要去除涂層以驗(yàn)證或測(cè)試基材的質(zhì)量或完整性。

4. Environmental requirements: In some industries, particularly building refurbishment or aircraft maintenance, coatings must be removed to meet environmental regulations or safety requirements.環(huán)境要求： 在某些行業(yè)，尤其是建筑物翻新或飛機(jī)維護(hù)，必須去除涂層以滿足環(huán)境法規(guī)或安全要求。

5. Restore original state: Coated with a protective layer for confidentiality and transportation safety, it can successfully pass the security inspection machines.恢復(fù)原狀：涂有保密和運(yùn)輸安全的保護(hù)層，可順利通過(guò)安檢機(jī)器檢查。
   

The process of stripping can be accomplished in a variety of ways, depending on the type of coating and substrate. Mechanical stripping is often done by grinding, sandblasting or scraping. Chemical stripping uses special solutions or chemicals to dissolve or dissolve the coating. Thermal decoating uses heat to soften or burn the coating.剝離過(guò)程可以通過(guò)多種方式完成，具體取決于涂層和基材的類型。機(jī)械剝離通常通過(guò)研磨、噴砂或刮擦來(lái)完成。化學(xué)剝離使用特殊溶液或化學(xué)品來(lái)滲透或溶解涂層。熱脫涂層使用熱量來(lái)軟化或燃燒涂層。

It is important that decoating is done properly to avoid damage to the substrate and to ensure that the surface is prepared for the desired application. The choice of decoating method depends on several factors, including the material of the substrate and the type of coating to be removed.正確進(jìn)行脫涂層以避免損壞基材并確保表面為所需的應(yīng)用做好準(zhǔn)備，這一點(diǎn)很重要。脫涂層方法的選擇取決于幾個(gè)因素，包括基材的材料和要去除的涂層類型。
