Apart from chemical cleaning, laser cleaning is an alternative choice for industrial or household applications, where it can be used to remove resin, oil, stains, filth, and coating or plating layers. It requires no grinding and can be applied to various types of materials. ITRI’s Energy-Saving Laser Descaling Agent Technology uses innovative pico-nano second dual pulsed laser technology, which can be easily installed and ready to use when plugged in. It is pre-calibrated with a simple one-switch operation, and users may finish cleaning chores without using chemical reagents, working medium, or water.

ITRI’s laser cleaning technology has a simple operating interface and lightweight handheld design.

ITRI’s laser cleaning technology is based on the utilization of high transient peak power of 50 kW pulsed laser on the object surface, where the stains instantly vaporize thereby attaining the goal of cleaning. Through the innovative pico-nano second dual pulsed laser technology, the pulse width and repetition rate are regulated to enhance absorption rate for the main processing and enable adequate cleaning for various materials. Moreover, because of the difference of the intermolecular absorption rate and thermal diffusion coefficient for different materials, stain removal can be accomplished without damaging the substrate.

The Energy-Saving Laser Descaling Agent Technology can effectively clean submicron particles adhering to the object surface which are difficult to remove completely by other approaches. It is a type of dry cleaning without the use of chemical solvents and thus will not result in environmental pollution. The residuals produced from the cleaning are recycled through a vacuum cleaner, and will not float in the air to cause health risks. In addition, three mechanisms are incorporated to prevent the laser from accidentally injuring human eyes: 360-degree infrared cut protective shield, four sets of object sensors on all sides of the laser protective shield, and defocus divergence optical protective design.

Energy-Saving Laser Descaling Agent Technology is mainly developed for environmental protection, hoping to significantly reduce the amount of energy and chemical cleaning agent usage. The technology has high efficiency and low cost; moreover, it is free of consumables and causes no harm to the skin. It is suitable for cleaning various types of stains on different surfaces, including stains on kitchenware and dining ware, bathroom tile mildew, wall mold, tap scale and rust corrosion on furniture. With its simple operating interface and lightweight handheld design, the technology is easy to use, making cleaning no longer a time-consuming and labor-consuming drudgery.
