In the rapid development of laser cleaning technology today, new directions and trends also continues to emerge in the field, of which compound laser cleaning technology is one of the highly potential and promising directions: it can improve the cleaning efficiency two to three times based on the same price.
What is compound laser cleaning?
As we all know, in the high-end laser cleaning market, in the case of the same cost expenditure earlier, the efficiency of laser cleaning will be lower than the traditional cleaning methods. Such as paint removal work of ship overhaul. The paint area of ship's side is very large. Some use chemical cleaning, some use high-pressure water cleaning. There are many shipyards proposing to use laser cleaning, but laser cleaning is limited by the power, the efficiency of the cleaning area of the thick paint layer in a unit of time, and it can not meet the requirements of shipyards.
Of course, technically speaking, with regard to improve efficiency, a simple superposition of power can be achieved. But in this way, the cost will also be increased dozens of times or even hundreds of times higher, not cost-effective at all. This means that efficient ship laser cleaning can only stay in theory, not enter the industrial application.
At present, the maximum power of domestic pulse laser is only 1000w, 2000W pure pulse laser is still in the debugging stage.
Compound laser cleaning technology is able to use 4000W continuous + 500W pulse to achieve 1000W pure pulse laser cleaning machine efficiency, 6000W continuous + 1000W pulse to achieve 2000W pulse cleaning machine efficiency.
The cleaning efficiency is increased by 2-3 times through process improvement on the basis of the same price. It has the advantages of improving the cleaning quality, increasing the cleaning efficiency, stabilizing the cleaning process, and being applicable to the cleaning of highly reflective materials etc., avoiding the shortcomings and deficiencies of single pulse cleaning.
Given that there is no domestic 2000W pulse laser cleaning machine, so 6000W continuous + 1000W pulse can be said to be the highest power laser cleaning equipment that can be put into production and stable use.
