Introduction
In modern industrial production, surface cleaning is a crucial step in ensuring product quality, extending equipment lifespan, and guaranteeing production process stability. With increasingly stringent environmental regulations and ever-increasing levels of production automation, companies' requirements for cleaning technology have gone far beyond simple decontamination; they now need to find the optimal solution between cleaning precision, production efficiency, environmental compliance, and total lifecycle cost.
Currently, mainstream cleaning methods in the industrial field include chemical cleaning, ultrasonic cleaning, high-pressure water jet cleaning, sandblasting/shot peening, dry ice cleaning, and the rapidly emerging laser cleaning. This article will systematically review the working principles, advantages, and limitations of these six technologies, and through multi-dimensional horizontal comparisons, highlight the unique value of laser cleaning technology in terms of precision, environmental protection, automation integration, and overall cost.
