　　Anti rust Strategy for Jinan Electric Complete Cabinet: Root Analysis and Long term Anti corrosion Process Analysis

　　机柜投入使用一段时间后，边角、接缝处悄悄出现锈迹，不仅严重影响外观整洁，长期锈蚀还会腐蚀柜体结构，降低柜体承重性与防护性，甚影响内部电气元件的稳定运行，这是很多用户都会遇到的运维痛点。看似不起眼的锈蚀问题，绝非小瑕疵，而是直接关乎电气成套设备使用寿命与运行的关键，绝大多数机柜生锈，并非使用损耗导致，核心根源在于**基材选型劣质**与**表面处理工艺不达标**，找准根源、选对材质工艺，才能彻底告别机柜生锈烦恼。

　　After the cabinet is put into use for a period of time, rust quietly appears at the corners and seams, which not only seriously affects the appearance cleanliness, but also corrodes the cabinet structure, reduces the load-bearing and protective capacity of the cabinet, and even affects the stable operation of internal electrical components. This is a pain point that many users encounter in operation and maintenance. The seemingly insignificant rusting problem is not a minor flaw, but a key issue directly related to the service life and operational safety of electrical equipment. The vast majority of cabinet rusting is not caused by wear and tear, but rather by poor substrate selection and substandard surface treatment processes. Only by identifying the root cause and selecting the right materials and processes can we completely bid farewell to the troubles of cabinet rusting.

　　电气成套机柜长期放置在车间、机房、地下室等场景，难免接触空气中的水汽、粉尘，部分潮湿、腐蚀性环境，更是会加速柜体锈蚀，而劣质机柜恰恰无法抵御这类环境侵蚀。从材质层面来看，普通冷轧板本身防锈性能极差，没有镀层防护的前提下，长期接触湿气，短短数月就会从边角、焊缝等薄弱位置开始生锈，这类板材成本低廉，是不良厂家压缩成本的常用选择，看似前期采购价更低，后期锈蚀返工、更换的成本反而更高。

　　Electrical complete sets of cabinets are placed in workshops, computer rooms, basements, and other environments for a long time, inevitably coming into contact with water vapor and dust in the air. Some humid and corrosive environments can accelerate cabinet corrosion, and inferior cabinets cannot resist such environmental erosion. From the perspective of material, ordinary cold-rolled plates have extremely poor rust prevention performance. Without high-quality coating protection, they can start rusting from weak positions such as corners and welds in just a few months after long-term exposure to moisture. This type of plate has low cost and is a common choice for manufacturers to reduce costs. It seems that the initial purchase price is lower, but the cost of rust rework and replacement in the later stage is actually higher.

　　表面处理工艺缺失，是机柜生锈的另一大核心诱因。很多低价机柜仅做简单喷涂，甚省略底漆工序，直接喷涂面漆，漆面附着力差、薄厚不均，使用过程中轻微磕碰就会掉漆，基材直接暴露在空气中，锈蚀会快速蔓延；还有部分厂家喷涂前未做好打磨、除油、除锈预处理，漆面与板材贴合不紧密，水汽轻易渗透漆面，形成内部锈蚀，从外观看短期内无异常，实则内部已经开始腐蚀，后期锈迹会直接鼓包、脱落。

　　The lack of surface treatment technology is another major cause of cabinet rust. Many low-priced cabinets only require simple spraying, and even omit the primer process, directly spraying the topcoat. The paint adhesion is poor and the thickness is uneven. During use, slight bumps can cause paint to peel off, and the substrate is directly exposed to the air, leading to rapid rusting; Some manufacturers have not done a good job of polishing, degreasing, and rust removal pre-treatment before spraying, resulting in poor adhesion between the paint surface and the board. Water vapor easily penetrates the paint surface, causing internal rust. From the appearance, there is no abnormality in the short term, but in fact, internal corrosion has already begun, and the rust will directly bulge and fall off in the later stage.

　　针对电气成套机柜的防锈需求，行业内成熟且长效的解决方案，是**优选镀锌板基材+底漆加粉漆双层喷涂工艺**，这也是电气成套厂家的标配工艺，耐腐蚀性相比普通板材工艺能提升数倍，从根源杜绝生锈问题。镀锌板本身带有锌层防护，锌层具备优异的防锈、防氧化性能，能在基材表面形成道防护屏障，隔绝水汽与空气，即便柜体表面出现轻微划痕，锌层也能起到牺牲阳极保护作用，延缓基材锈蚀，适配潮湿、半露天等各类复杂环境。

　　The mature and long-term solution for the rust prevention needs of electrical complete cabinets in the industry is the * * preferred galvanized sheet substrate+primer+powder paint double-layer spraying process * *, which is also a standard process for professional electrical complete manufacturers. Compared with ordinary sheet technology, the corrosion resistance can be improved several times, eliminating rust problems from the root. Galvanized sheet itself is protected by a zinc layer, which has excellent rust and oxidation resistance. It can form the first protective barrier on the surface of the substrate, isolating water vapor and air. Even if there are slight scratches on the surface of the cabinet, the zinc layer can serve as sacrificial anode protection, delaying substrate rust corrosion and adapting to various complex environments such as humidity and semi exposure.

　　底漆加粉漆的双层表面处理工艺，是第二道核心防护。先均匀喷涂专用防锈底漆，增强漆面附着力，进一步封闭板材孔隙，杜绝水汽渗透；再采用静电粉末喷涂工艺，覆盖面漆，粉漆漆面厚度均匀、硬度高、耐磨抗刮，附着力远超普通喷漆，不易掉漆、褪色，双重漆面搭配镀锌基材，形成“基材+底漆+面漆”叁层防护体系，阻隔腐蚀因素，即便长期在恶劣环境下使用，也能保持柜体完好，彻底告别边角生锈、漆面脱落的困扰。

　　The double-layer surface treatment process of primer and powder paint is the second core protection. First, evenly spray the special anti rust primer to enhance the adhesion of the paint surface, further seal the pores of the board, and prevent water vapor penetration; Using electrostatic powder spraying technology to cover the topcoat, the powder paint surface has a uniform thickness, high hardness, wear resistance, and scratch resistance, with adhesion far exceeding that of ordinary spray paint. It is not easy to peel off or fade. The dual paint surface is combined with galvanized substrate to form a three-layer protection system of "substrate+primer+topcoat", which comprehensively blocks corrosion factors. Even if used in harsh environments for a long time, it can keep the cabinet intact and completely say goodbye to the troubles of rust and paint peeling at the corners.

　　在电气成套设备领域，机柜作为核心载体，承担着保护内部电气元件、规整线路、保障设备运行的重要作用，防锈性能是衡量机柜品质的核心指标。选购时切勿只看重低价，忽略材质与工艺，优先选择镀锌板基材、双层喷涂工艺的机柜，提前规避生锈风险。

　　In the field of electrical complete equipment, the cabinet serves as the core carrier and plays an important role in protecting internal electrical components, regulating circuits, and ensuring the safe operation of equipment. Rust prevention performance is the core indicator for measuring the quality of the cabinet. When choosing, do not only focus on low prices and ignore materials and processes. Prioritize high-quality cabinets with galvanized sheet substrates and double-layer spraying processes to avoid the risk of rust in advance.

　　的电气成套定制，始终把材质选型与防腐工艺放在首位，从源头把控产物品质，拒绝劣质基材与简化工艺，针对不同使用环境，定制适配的防腐方案，确保机柜耐用性与性。对于已经出现锈蚀的机柜，也需及时做好除锈补漆处理，避免锈蚀范围扩大，影响设备正常运行。选对基材与工艺，才能让电气成套机柜长效耐用，省去后期运维烦恼，保障整套电气设备稳定运行。

　　Professional electrical complete set customization always puts material selection and anti-corrosion technology in the first place, controls product quality from the source, rejects inferior substrates and simplified processes, customizes suitable anti-corrosion solutions for different usage environments, and ensures the durability and safety of cabinets. For cabinets that have already been corroded, timely rust removal and paint repair treatment should also be carried out to avoid the expansion of the corrosion range and the impact on the normal operation of the equipment. Only by selecting the right substrate and process can the complete electrical cabinet be long-lasting and durable, saving the trouble of later operation and maintenance, and ensuring the stable and efficient operation of the entire electrical equipment.
