Application of 100W Laser Cleaning Machine on bronze cultural relics

The cleaning of bronze cultural relics is one of the main problems in the protection and restoration of cultural relics. It is of great research value and significance to use advanced laser technology to clean bronze cultural relics without damage. At present, laser cleaning technology, as a new cleaning technology, can quickly and effectively remove the dirt on the surface of cultural relics on the basis of protecting the cultural relics themselves, compared with the traditional technology has great advantages. The following describes the application of laser cleaning machine on bronze cultural relics.

100W Laser Cleaning Machine as a new cleaning technology has been more and more widely used in various fields. Laser cleaning is the use of laser beam characteristics, through the concentrating system can make the laser beam gathered into different sizes of spot diameter, under the same laser energy conditions, different spots of the laser beam, the energy density or power density is different, so that you can easily control the cleaning required laser energy. Lasers can achieve high concentration in time and space. Laser cleaning is the use of these characteristics to effectively remove pollutants. Wuhan Ruifeng photoelectric laser is one of the first batch of laser equipment production enterprises, with more than 10 years of R & D production experience, leading peer enterprises in technology and integration. Since its establishment, the company always pays attention to the research and development of laser technology and the development needs of customers, is committed to providing perfect material processing solutions for each customer.

The traditional cleaning methods include mechanical cleaning method, chemical cleaning method and ultrasonic cleaning method. Although they are widely used in the cleaning industry, their application is greatly limited under the requirements of environmental protection and high precision. Mechanical method can not meet the requirements of high cleanliness cleaning, and chemical cleaning method is easy to lead to environmental pollution, cleanliness is also very limited; Especially when the composition of dirt is complex, a variety of cleaning agents must be used to repeatedly clean the surface to meet the requirements of cleanliness. Ultrasonic wave can not clean submicron particles, the size of the cleaning tank limits the scope and complexity of cleaning parts, and the drying of the workpiece after cleaning is also a big problem. Laser cleaning technology is a new cleaning technology developed rapidly in recent ten years, and is gradually replacing the traditional cleaning technology in many fields. It can adapt to all kinds of surface dirt cleaning, minimal environmental pollution, but also can do not damage the matrix.

At present, this method has become the supplement and extension of traditional cleaning method and has broad application prospect. Compared with traditional cleaning methods, laser cleaning technology has some unique advantages:

(1) laser cleaning is a kind of selective cleaning, that is, to clean the object can be selective, this technology can make the matrix surface intact. For different dirt on different substrate surface, it can selectively clean dirt by setting laser parameters (such as spot size, single pulse energy, pulse width, repetition frequency, etc.) without damaging the substrate.

(2) the environmental protection of laser cleaning. Laser cleaning waste is basically solid powder, small volume, easy to store, basically does not cause pollution to the environment, is a "green" cleaning process.

(3) Accurate positioning. The laser beam can be precisely positioned on the surface of the material to be cleaned, and the spot area can be adjusted from a few tenths of a millimetre to one centimetre. Can be used to clean irregular or concealed surfaces. The laser head, or the fiber conducting the laser, can be placed on a movable three-dimensional platform to position the laser beam on the surface of the material to be cleaned. Computer control can be used to make the positioning more accurate and automatic.

(4) non contact of laser cleaning. The traditional method is often close to the operation, cleaning the surface of the object has mechanical force, easy to damage the surface of the object. And laser cleaning is a kind of non-contact processing, can easily achieve remote operation, can be transmitted through optical fiber, and robot or manipulator joint, can clean the traditional method is not easy to reach parts. Transfer energy in the form of light without mechanical contact. This allows you to clean surfaces of very fragile materials.

Above is the laser cleaning machine in bronze relics on the cleaning applications, laser cleaning technology at home and abroad have been successfully applied in bronze derusting experience, as long as according to the actual corrosion of bronze ware, suitable for laser and laser process parameters, the effect of removing the rust is more ideal, also won't cause damage to bronze substrate. At the same time, it can form a dense layer of passivation and rust removal effect is ideal, and will not cause damage to the bronze matrix.
