In industry, the feeling of equipment is so intuitive and solid. However, environmental factors are one of the important causes of product failure. Any equipment works in a certain environment, and humidity, salt spray and mold will reduce the insulation strength of the material, causing leakage and short circuit, resulting in failures and accidents. The three-proof design is an important guarantee for the normal operation of the product in various environments, mainly referring to the moisture-proof design, salt spray-proof design, and mold-proof design.

In the field of three defenses, waterproof design is very critical, for example, the strength of the overall rubber shell should meet the grade requirements; The fixing screws are evenly distributed and the stress on the shell should be uniform. The design of the sealing surface ensures the plane as much as possible, and the arc transition at the corner is ensured. The sealing surface ensures smooth and clean surface. This requires strong adhesion.

The adhesion is very important to the selection of materials. To achieve material protection, it mainly refers to the correct and reasonable selection of materials. At the same time, the internal structure of metal materials is improved through cold, hot processing and heat treatment measures, and the modification of non-metal materials further improves the material Corrosion resistance.
Anti-corrosion design When starting structural design, it is first necessary to understand or locate the working environment of the product and the service life of the product, determine the types of structural parts in the product, and then make detailed selection and design according to the functional purpose of the parts. In the detailed design process, each part needs to be considered from the structural shape, stress state, material, outer protective layer, production and processing, assembly, storage and transportation, working life and other environmental conditions related to it, so that the parts can not only meet the functional requirements, but also achieve the optimal anti-corrosion state.

When selecting materials, we should understand the compatibility of materials, master the corrosion mechanism of materials, destruction type, etc. In order to ensure that the structural design can avoid some dangerous forms of corrosion, to prevent different materials from interacting with each other, mutual influence caused by corrosion, aging, etc. Therefore, it is extremely important to reasonably select coatings and different types of metals according to the compatibility of materials.

In the design of industrial equipment, designers also need to carry out various tests in strict accordance with industry standards, such as common waterproof tests, anti-corrosion tests, shockproof tests, etc., so that the products have excellent performance in waterproof and shockproof, such as IP67 industrial grade, which can adapt to various complex working environments. In terms of human-computer interaction, the user interface design of the three-proof equipment needs to conform to ergonomics, reasonable layout, clear and clear signs, and comfortable keys, so that users are easy to operate, easy to read information, and improve work efficiency.
