Laser cleaning is fast, efficient, and saves time. Although purchasing a laser cleaning system has a high one-time investment, the cleaning system can be used stably for a long time, the operating cost is low, and more importantly, it can be easily automated. Cost calculation: The cleaning efficiency of a single unit is 8 square meters per hour, and the operating cost is about 5 degrees per hour, which means that the cleaning cost is 4 cents per square meter. Excluding the initial cost, 4 cents per square meter is later.
