大型飛機(jī)模型是否會生銹主要取決于其制作材料。如果模型部分部件是金屬材質(zhì)，在一定條件下是會生銹的；如果是塑料、木質(zhì)或復(fù)合材料等非金屬材質(zhì)的模型，則通常不會生銹。以下是金屬材質(zhì)飛機(jī)模型生銹的原因及處理方法：

Whether a large aircraft model will rust mainly depends on its manufacturing materials. If some parts of the model are made of metal, they will rust under certain conditions; If the model is made of non-metallic materials such as plastic, wood, or composite materials, it usually does not rust. The following are the reasons and treatment methods for rusting of metal aircraft models:

生銹原因

Reasons for rusting

材質(zhì)因素：如果模型使用的金屬材料本身防銹性能較差，如普通的鐵制品，就容易生銹。而一些合金材質(zhì)，如不銹鋼、鋁合金等，具有較好的防銹性能，但在某些特定環(huán)境下，也可能會出現(xiàn)腐蝕生銹的情況。

Material factor: If the metal material used in the model has poor rust prevention performance, such as ordinary iron products, it is easy to rust. Some alloy materials, such as stainless steel and aluminum alloy, have good anti rust properties, but corrosion and rusting may also occur in certain specific environments.

環(huán)境因素：濕度是導(dǎo)致金屬模型生銹的重要因素之一。當(dāng)空氣中的相對濕度達(dá)到一定程度（一般認(rèn)為相對濕度超過 60%）時(shí)，金屬表面會形成一層薄薄的水膜，這層水膜會加速金屬的氧化反應(yīng)，從而導(dǎo)致生銹。此外，空氣中的污染物，如二氧化硫、氯化物等，也會與金屬發(fā)生化學(xué)反應(yīng)，加速生銹過程。

Environmental factors: Humidity is one of the important factors that cause rusting of metal models. When the relative humidity in the air reaches a certain level (generally considered to be over 60%), a thin water film will form on the metal surface, which will accelerate the oxidation reaction of the metal, leading to rust. In addition, pollutants in the air, such as sulfur dioxide and chlorides, can also undergo chemical reactions with metals, accelerating the rusting process.

輕度生銹

Mild rusting

物理打磨：可以使用柔軟的砂紙或鋼絲絨輕輕擦拭生銹部位，將銹跡打磨掉。在打磨時(shí)要注意力度，避免刮傷模型表面。對于一些細(xì)節(jié)部位，可以使用牙簽或棉簽蘸取少量除銹劑進(jìn)行局部處理。

Physical polishing: You can use soft sandpaper or steel wool to gently wipe the rusted area and polish off the rust. When polishing, pay attention to the strength to avoid scratching the surface of the model. For some details, a toothpick or cotton swab dipped in a small amount of rust remover can be used for local treatment.

化學(xué)除銹：市面上有專門的金屬除銹劑，將除銹劑噴在生銹部位，然后用干凈的布擦拭干凈。除銹后，要及時(shí)用清水沖洗干凈，并擦干模型表面，防止除銹劑殘留對模型造成進(jìn)一步腐蝕。

Chemical rust removal: There are specialized metal rust removers available on the market. Spray the rust remover onto the rusted area and then wipe it clean with a clean cloth. After rust removal, it is necessary to rinse with clean water in a timely manner and dry the surface of the model to prevent further corrosion of the model caused by residual rust remover.

重度生銹

Severe rusting

專業(yè)修復(fù)：如果生銹情況比較嚴(yán)重，可能需要將模型送到專業(yè)的模型修復(fù)店進(jìn)行處理。專業(yè)人員會根據(jù)模型的具體情況，采用更復(fù)雜的修復(fù)工藝，如電解除銹、化學(xué)鍍等方法來去除銹跡，并對模型進(jìn)行修復(fù)和保養(yǎng)。

Professional repair: If the rust is severe, it may be necessary to send the model to a professional model repair shop for processing. Professional personnel will use more complex repair processes, such as electrolytic rust removal and chemical plating, to remove rust and repair and maintain the model based on its specific situation.

重新涂裝：在除銹完成后，為了防止模型再次生銹，可以對模型進(jìn)行重新涂裝。先對模型表面進(jìn)行清潔和打磨，然后噴上底漆，待底漆干燥后，再噴上面漆。選擇質(zhì)量好、防銹性能強(qiáng)的油漆，可以有效延長模型的使用壽命。

Repainting: After rust removal is completed, to prevent the model from rusting again, it can be repainted. First, clean and polish the surface of the model, then spray the primer. After the primer dries, spray the topcoat. Choosing paint with good quality and strong rust resistance can effectively extend the service life of the model.

為了防止大型飛機(jī)模型生銹，在日常保養(yǎng)中，應(yīng)盡量將模型放置在干燥、通風(fēng)良好的環(huán)境中，避免陽光直射和潮濕的環(huán)境。也可以定期給模型涂抹一些防銹油或保護(hù)漆，增強(qiáng)其防銹能力

In order to prevent large aircraft models from rusting, during daily maintenance, the models should be placed in a dry, well ventilated environment as much as possible, avoiding direct sunlight and humid environments. You can also regularly apply some anti rust oil or protective paint to the model to enhance its anti rust ability
