After the chemical pipeline has been used for a certain period of time, impurities are usually attached to the inner wall of the pipeline. Therefore, the inner wall of the pipeline needs to be cleaned after the pipeline has been operated for a certain period of time to ensure the quality of the medium transported by the pipeline. At present, the removal methods of sundries on the inner wall of the pipeline include chemical cleaning method and sand blasting derusting method. Because the chemical cleaning agent used in the chemical cleaning method contains harmful substances, many enterprises will choose sand blasting derusting method at present. However, the sandblasting method will make the inner wall rough and pollute the environment. After 2020, when China's environmental protection laws and regulations are increasingly strict and people's awareness of environmental protection and safety is increasingly enhanced, many enterprises need environmentally friendly and efficient cleaning methods.
Laser cleaning is an efficient and green cleaning technology, which has certain advantages over chemical cleaning and mechanical cleaning. It does not require any chemical reagent, no grinding, no stress, no consumables, non-contact, no thermal effect on the substrate, and so on; The laser can be guided by optical fiber transmission, and can clean the parts that are not easy to reach. It has a wide range of applications, including rust removal, paint removal, mud removal, and wafer surface treatment; High cleanliness is considered to be a more reliable and effective solution.
Multidimensional laser cleaning machine
Multi-dimensional laser cleaning machine is very effective when it uses nanometer laser radiation to clean the workpiece surface. Because the laser cleans the workpiece without contact, it is very safe to clean the precision workpiece or its fine parts, which can ensure its accuracy. It replaces the original manual grinding and scraping, greatly improving efficiency and solving labor problems. Therefore, laser cleaning has unique advantages in the cleaning industry.
When working, the laser pulse of multi-dimensional laser cleaning machine can remove the pollution layer in the pipe wall. If the contamination layer is thick, multiple pulses are required for cleaning. The number of pulses required to clean the surface depends on the degree of surface contamination. An important result produced by the two thresholds is the self-control of cleaning. The pulse with energy density higher than the first threshold will remove pollutants until it reaches the substrate.
However, because its energy density is lower than the damage threshold of the base material, the substrate will not be damaged. This laser cleaning principle can completely replace the traditional cleaning method, which is safe, environmentally friendly, reliable and efficient.
Application scope and field of multidimensional laser cleaning machine:
1. Remove the coating on the metal or glass surface and quickly remove the paint. 2. Rapid rust removal and various oxides. 3. Remove grease, resin, glue, dust, stain and production residue. 4.
