In recent years, with the rapid development of laser related technologies in our country, the application of laser cleaning machines has become more and more common and has attracted widespread attention. But most people don't know much about laser cleaning equipment. What is the price based on? What are the advantages and disadvantages?
After reading this article, you will have a general understanding!
1. The Price Of Laser Cleaning Machine
The first concept to be clear is that it is difficult for laser cleaning machines to have a fixed price, only a general price range. This is because laser cleaning machines are generally custom-made.
The same is a 200W air-cooled handheld laser cleaning machine. Some manufacturers use it to remove rust, paint, and carbon deposits on tire molds, and some manufacturers use it to decoat chip PCB circuit boards. The former may need to be faster and more efficient, and the control system will It is required to install PIC, and the latter wants to be able to monitor relevant data in real time, so it will require the installation of PLC; whether it is Gaussian light or flat-top light, pulse or continuous, QCS or QBH, it must be determined in detail.
And in order to achieve the best cleaning effect on the corresponding substrate to be cleaned, it is usually necessary to adjust the corresponding parameters such as fiber length, field lens focal depth, output power, pulse width and scanning speed according to the characteristics of different substrates.
The prices of laser cleaning machines of the same model in the low-power section are often slightly different, let alone those in the ultra-high-power section: composite laser cleaning machines with a power of more than 8000W used to remove paint from large-scale equipment such as aerospace, ships, and high-speed rail Machines are generally redesigned and manufactured according to the customer's equipment site, use environment and other conditions, and the price is often determined only after on-site measurement.
It can be said that the laser cleaning machines purchased by different customers will not be exactly the same. That's why it's not priced exactly.
So you still have to communicate well according to your own needs, and don't be too obsessed with fixing prices.
2. What Are The Advantages And Disadvantages Of Laser Cleaning Machines?
So what are the advantages and disadvantages of laser cleaning machines compared with other cleaning methods?
The advantage is that it is superior to almost all traditional industrial cleaning methods in terms of cleaning ability technology and process;
The disadvantage is that the development time is too short and the development speed is not fast enough. At present, it has not yet covered the full scope of industrial cleaning.
Traditional industrial cleaning has various disadvantages:
Sand blasting will cause damage to the substrate and produce a large amount of dust pollution. If the sand blasting is carried out in a closed box with low power, the pollution will be relatively small. If sand blasting with high power is carried out in an open space, it will bring huge dust problems;
Wet chemical cleaning will have cleaning agent residues, the cleaning efficiency is not high enough, it will affect the acidity and alkalinity of the substrate and the hydrophilicity and hydrophobicity of the surface, and will cause environmental pollution;
The cost of dry ice blasting is high. For example, the tire factory in China, which ranks around 20-30, uses dry ice blasting technology to spend close to 800,000-1.2 million consumables a year. And the secondary waste it produces is inconvenient to recycle;
Ultrasonic cleaning cannot remove the coating, cannot clean soft materials, and is powerless to submicron particle pollution;
Generally speaking, these cleaning processes have various inconveniences and cannot meet the requirements of environmental protection or efficiency in the cleaning process of the manufacturing industry.
The advantage of laser cleaning is that it can realize non-contact, more precise cleaning at the technical level, remote control, selective removal, and semi-automatic or fully automatic unmanned workshop. For example, in the application of selective paint removal, laser cleaning can accurately remove a certain layer at the micron level, and the surface quality after removal can reach Sa3 level (the highest level), and the surface hardness, roughness, hydrophilicity and hydrophobicity can be maximized. Save as much as it is.
At the same time, the unit cost, energy consumption, efficiency and other aspects are better than other cleaning methods. For the environment, it can achieve industrial-grade zero pollution.
As for the disadvantages, the disadvantage of the laser cleaning machine is that the development speed is not fast enough. At present, it has not yet covered the entire scope of industrial cleaning, and the industrial fields with large-scale applications are basically concentrated in the mid-end markets such as molds and metal materials.
In some low-end markets where manual grinding is used, angle grinders, wire brushes, and scrapers are used to remove paint and rust, the laser cleaning machine is too bulky. At present, the smallest laser cleaning machine on the market is also the size of a suitcase, and the world's smallest laser cleaning machine The head is a fifth-generation laser head developed by Waterdrop Laser, which is as big as a cigarette box. It can basically meet the needs of manufacturers, but compared with traditional tools, it still needs further improvement.
In the high-end cleaning market, such as the paint removal work of ship overhaul, although many shipyards propose to use laser cleaning, the current laser cleaning is still unable to reach the shipyard's efficiency compared with traditional methods such as chemical cleaning and high-pressure water cleaning.
But the iteration of technology is rapid. In 2016, China's first laser cleaning machine came out; in 2018, the laser cleaning machine was still at the 100W level; in 2019, the fiber laser technology broke through 1000W; in 2020, the power of the fiber laser for cleaning only broke through 2000W.
Last year, the water droplet laser led the market and took the lead in breaking through the equipment technology of 6000W laser cleaning machine. At present, it has been able to achieve 8000W composite laser cleaning. It is believed that industrial cleaning covering the full range of power ranges will be within the past two years.
As the requirements for carbon emissions become more and more stringent, the red-headed documents for the transformation and upgrading of the manufacturing industry are becoming more and more clear. Green, environmentally friendly, efficient and energy-saving laser cleaning is gradually reducing the dimensionality of industries such as sandblasting and wet chemical cleaning.
I believe that in the near future, laser cleaning will replace the traditional cleaning industry and become a subversive in the field of industrial cleaning!
