Superiority Of Laser Cleaning Machine
Jul 23, 2018

The traditional cleaning industry has a variety of cleaning methods, mostly using chemical and mechanical methods for cleaning. Today, China's environmental protection regulations are becoming more stringent, and people's awareness of environmental protection and safety is increasing. The types of chemicals that can be used in industrial production cleaning will become less and less. How to find a cleaner, non-damaging cleaning method is a problem we have to consider. Laser cleaning has the characteristics of no grinding, non-contact, no heat effect and cleaning of objects suitable for various materials, and is considered to be the most reliable and effective solution. At the same time, laser cleaning can solve problems that cannot be solved by traditional cleaning methods.

The physical principle of laser cleaning

The beam emitted by the laser is absorbed by the layer of contaminants on the surface to be treated. The absorption of large energy forms a rapidly expanding plasma (a highly ionized unstable gas) that generates a shock wave. The shock wave turns the contaminants into pieces and is rejected.

Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid solid impact cleaning, high frequency ultrasonic cleaning, laser cleaning has five distinct advantages:

Environmental advantages: Laser cleaning is a “green” cleaning method. No chemicals or cleaning liquids are needed. The wastes washed are basically solid powders. They are small in size, easy to store, recyclable, and have no photochemical reaction. It will cause pollution. Environmental pollution problems caused by chemical cleaning can be easily solved. 2. A blower can often solve the waste problem caused by cleaning.

Advantages of the effect: The traditional cleaning method is often contact cleaning, which has mechanical force on the surface of the cleaning object. The surface of the damaged object or the cleaning medium adheres to the surface of the object to be cleaned, cannot be removed, and causes secondary pollution, no laser cleaning. Grinding and non-contact, no thermal effects do not damage the substrate, making these problems easy to solve.

Control advantage: The laser can be transmitted through optical fiber, cooperate with the robot and the robot, and can easily realize long-distance operation. It can clean the parts that are difficult to reach by traditional methods. This can be used in some dangerous places to ensure the safety of personnel.

Convenient advantage: Laser cleaning removes all types of contaminants from the surface of various materials to the level of cleanliness that cannot be achieved with conventional cleaning. It is also possible to selectively clean contaminants on the surface of the material without damaging the surface of the material.

Cost advantage: laser cleaning speed is fast, high efficiency, saving time; although the laser cleaning system is purchased at a high level in the early stage, the cleaning system can be used stably for a long time, the running cost is low, and more importantly, the automatic operation can be conveniently realized. Cost calculation: a single cleaning efficiency of 8 square meters per hour running cost of about 5 degrees of electricity, that is, cleaning costs of 4 cents per square meter, in addition to the initial cost, the latter 4 cents per square meter.

Introduction to the use of laser cleaning in various fields

Laser cleaning technology is a new type of cleaning technology that has developed rapidly in the past 10 years. It has gradually replaced traditional cleaning processes in many fields with its own advantages and irreplaceability. Laser cleaning can be used not only to clean organic contaminants, but also to clean inorganic materials, including metal rust, metal particles, dust, etc. Here are some practical applications. These technologies are very mature and have been widely used.
