Laser Cleaning Helps Cast Aluminum Door Handles Look New Like

With the continuous advancement of science and technology, laser cleaning technology, as an emerging cleaning method, has gradually received attention in recent years. Laser cleaning uses high-energy laser beams to instantly evaporate or peel off dirt, rust and other contaminants on the surface. It is not only highly efficient, but also has almost no damage to the cleaned surface. This technology has shown great application potential in many fields such as industrial manufacturing, art restoration, and environmental protection, and has become a highlight of the modern cleaning industry.

Among many applications, cast aluminum door handles, as one of the common building hardware, often face problems such as surface dirt, oxidation and corrosion. Due to the particularity of cast aluminum materials, its surface will gradually lose its luster, become dull and fragile during long-term use, affecting the appearance and service life of the product. Traditional cleaning methods, such as using chemical cleaners or physical abrasion cleaning, often have some limitations. Not only may it cause scratches and damage to the surface, but it also requires the use of a large amount of chemicals, which may have a negative impact on the environment. In addition, the efficiency of traditional cleaning methods is relatively low, and the cleaning effect is not satisfactory. Therefore, it is particularly important to explore a more efficient and environmentally friendly cleaning method, and laser cleaning technology happens to provide a feasible solution.

Laser cleaning technology is an advanced method that uses the high energy density of laser beams to clean the surface of an object. It uses the focusing characteristics of lasers and the principle of interaction with matter to remove dirt, rust, coatings and other contaminants on the surface through high temperature and high energy. This cleaning method has been widely developed and applied in recent years and has become an important technology in the field of industrial cleaning and maintenance.

1. Definition

Laser cleaning is an advanced technology that uses high-energy laser beams to clean the surface of an object non-contactly. The basic concept is to focus the laser energy on the surface of the object, instantly heating and removing contaminants such as dirt, rust, coatings. Laser cleaning is widely used in many fields such as industry, art restoration, and environmental protection.

2. Working principle

The working principle of laser cleaning mainly depends on the following processes:

Laser absorption: When the laser beam contacts the surface of the material, the laser of a specific wavelength can be absorbed by dirt, rust and coating. The substrate (such as aluminum, steel, etc.) can usually reflect the laser and is therefore not easily damaged.

Thermal effect: The added heat causes the contaminant to heat up rapidly to the critical point of evaporation or melting. This process is extremely fast and can be completed within a time scale of microseconds to nanoseconds.

Gas expansion: Due to the increase in heat, the gas generated after the pollutant evaporates expands rapidly, forming a shock wave, which removes dirt and coating from the surface of the substrate.

Non-destructive substrate: Since the positioning and energy of the laser can be precisely controlled, in most cases, the substrate will not be damaged and its performance and appearance will be maintained.

3. Technical advantages

● Environmental protection

No chemical solvents: Laser cleaning does not require the use of chemicals or cleaning agents, which reduces the risk of environmental pollution and toxicity and meets modern environmental protection requirements.

Low waste generation: Laser cleaning process hardly produces wastewater, waste gas and other pollutants, and the treated waste is usually discharged in the form of gas, which is easy to manage and handle.
