3. ORGANIC FINISHES 有机面漆

WARNING :MANY OF THE STRIPPING SOLUTIONS ARE FLAMMABLE, POISONOUS OR CAN CAUSE CORROSION. DO NOT BREATHE SOLVENT AND STRIPPING SOLUTION VAPORS. THESE MATERIALS MUST NOT BE USED IN CONFINED SPACES WITHOUT SUFFICIENT VENTILATION. EXHAUST VENTILATION MUST BE SUPPLIED OVER OPEN SOLUTION TANKS. KEEP STRIPPING SOLUTIONS AWAY FROM SKIN. WEAR CHEMICAL-RESISTANT GLOVES. IF STRIPPING CHEMICALS COULD SPLASH, WEAR GOGGLES OR PROTECTIVE FACE SHIELD AND CHEMICAL-RESISTANT CLOTHING. IMMEDIATELY WASH OFF SOLUTION THAT GETS ON YOUR SKIN. FLUSH OUT WITH WATER ANY SOLUTION THAT IS SPLASHED INTO YOUR EYES, AND GET MEDICAL AID.

警告 :许多剥离溶液易燃、有毒或可导致腐蚀。切勿吸入溶剂和剥离液蒸汽。在没有充分通风的密闭空间内不得使用这些材料。必须在敞开的溶液罐上进行排气通风。让剥离溶液远离皮肤。戴上防化学腐蚀手套。如果剥离化学品可能飞溅，请戴上护目镜或防护面罩，并穿上防化服。立即清洗沾到皮肤上的溶液。用水冲洗溅入眼内的溶液，并寻求医疗救助。

CAUTION :DO NOT LET CHEMICAL STRIPPERS GET ON SEALS, SEALANT, OR FILLET SEALS, OR FLOW INTO FAYING SURFACES OF BONDED OR SEALED JOINTS.

注意 :不要让化学剥离剂沾到密封件、密封胶或圆角密封件上，也不要让其流入已粘合或密封接缝的接合面。

A. Organic finishes include paints, enamels, varnishes, lacquers and some elastomeric and polymerized resin finishes.

有机饰面包括涂料、瓷漆、清漆、油漆和某些弹性体及聚合树脂饰面。

B. Stripping Methods

剥离方法

(1) Immersion stripping is preferred for detail parts. Do not use on assemblies. A stripping solution with a water seal (aqueous seal) contains two layers. Stripping takes place in the lower (inner) layer, and the upper (outer) layer prevents escape of active stripper material.

细节零件宜采用浸泡剥离法。不得用于组件。带水密封（水密封）的剥离液包含两层。剥离在下层（内层）进行，而上层（外层）可防止活性剥离材料溢出。

(2) Spray or brush-on stripping can be used on unsealed assemblies and detail parts too large to fit in an immersion tank, and for areas not loosened during immersion stripping. These strippers contain thickening agents that slow down evaporation. These strippers can be applied to vertical or horizontal surfaces.

喷涂或刷涂剥离剂可用于未密封的组件和细节零件，这些零件太大，无法放入浸泡槽，也可用于浸泡剥离过程中未松动的区域。这些剥离剂含有增稠剂，可减缓蒸发。这些剥离剂可用于垂直或水平表面。

(3) Chemical wipe or squirt-on stripping is used to remove wax-type materials that can be dissolved in solvent and then wiped off. Examples are crayon marks, temporary coatings and overspray.

化学擦拭或喷涂剥离用于去除可溶解在溶剂中然后擦掉的蜡型材料。例如蜡笔痕迹、临时涂层和过喷。

(4) Dry abrasive stripping

干磨剥离

(a) Conventional abrasive blasting or dry sanding can be used for ferrous alloys, titanium, nickel, and magnesium. Use soft abrasive grains on metal surfaces. Use dry sanding on composite surfaces.

对于铁合金、钛、镍和镁，可使用传统的喷砂或干磨。在金属表面使用软磨粒。在复合材料表面使用干砂。

(b) Plastic media blasting can be usead (bare) aluminum 0.125 inch or thicker, ferrous alloys, titanium, parts plated with cadmium-titanium, cadmium, nickel, zinc-nickel, chrome, and copper, and chemically treated or anodized magnesium. Do not strip to bare magnesium. Plastic media blasting damages plating and surface treatments such as chemical conversion and anodized coatings. All plating (other than chrome plate) and surface treatments must be removed by the procedures for inorganic find on non-clishes specified in Paragraph 塑料介质喷丸可用于 0.125 英寸或更厚的无包层（裸）铝、铁合金、钛、镀有镉钛、镉、镍、锌镍、铬和铜的零件，以及经过化学处理或阳极氧化处理的镁。切勿将镁剥至裸露。塑料介质喷丸会损坏电镀和表面处理，如化学转化和阳极氧化涂层。所有镀层（铬板除外）和表面处理必须按照第 4 段规定的无机表面处理程序进行清除。

(c) Wheat starch blasting can be used for clad and non-clad aluminum 0.032 inch or thicker, bonded aluminum honeycomb sandwich parts with face sheets 0.012 inch or thicker, all other metals, including plated surfaces, and composites such as Kevlar, graphite and fiberglass. Complete removal of organic materials by wheat starch media damages surface treatments on the base metal such as chemical conversion and anodized coatings, and can remove plating. After removal of the organic finishes, remove the remaining surface treatments by the procedure for inorganic finishes specified in Paragraph 4.

小麦淀粉喷砂可用于 0.032 英寸或更厚的包层铝和非包层铝、面片厚度为 0.012 英寸或更厚的粘合铝蜂窝夹层零件、所有其他金属（包括电镀表面）以及Kevlar、石墨和玻璃纤维等复合材料。用小麦淀粉介质完全去除有机物会破坏基体金属的表面处理，如化学转化和阳极氧化涂层，并可能去除电镀层。去除有机饰面后，按第 4 段规定的无机饰面程序去除剩余的表面处理。

(d) Nanocomposite blasting can be used for aluminum 0.040 inch or thicker, and bonded aluminum honeycomb sandwich parts with aluminum face sheets 0.012 inch or thicker, ferrous alloys, titanium alloys, parts plated with cadmium-titanium, cadmium, nickel, zinc-nickel, chrome and copper, and chemically treated or anodized magnesium. There are three Magic types of nanocomposite abrasive media. Magic 1 is for general-purpose stripping. Magic 2 gives a faster removal rate. Magic 3 is used to remove cured sealant.

纳米复合喷砂可用于 0.040 英寸或更厚的铝，以及铝面片厚度为 0.012 英寸或更厚的粘合铝蜂窝夹层零件、铁合金、钛合金、镀有镉-钛、镉、镍、锌-镍、铬和铜的零件，以及经化学处理或阳极氧化处理的镁。纳米复合研磨介质有三种 Magic 类型。Magic 1 适用于通用剥离。Magic 2 的剥离速度更快。Magic 3 用于清除固化密封胶。
