Dustproofing refers to the process of making an object or space resistant to dust accumulation. This is often achieved through the use of seals, barriers, or coatings that prevent dust particles from entering or settling on surfaces. Common applications include electronics, machinery, and buildings, where dust can cause damage or reduce efficiency. In many cases, dustproofing is essential for maintaining cleanliness and functionality. For example, electronic devices often have dustproof enclosures to protect sensitive components. Similarly, industrial equipment may be designed with dustproof features to ensure optimal performance in dusty environments, thereby extending the lifespan of the equipment.
