Performance characteristics of waste hydrocarbon cleaning agent recycling:
1. Good cleaning performance: Carbon hydrogen cleaning agents, along with most stamping oils, rust proof oils, and machining oils, are petroleum fractions. According to the principle of similar solubility, the effect of carbon hydrogen cleaning agents on cleaning these mineral oils is better than that of halogenated hydrocarbons and water-based cleaning agents.
2. Low evaporation loss: The boiling point of hydrocarbon cleaning agents is generally above 160 ℃. During use and storage, the evaporation loss is much smaller than that of halogenated hydrocarbons at 40-80 ℃, and the sealing requirements for packaging and equipment are very low.
3. Good material compatibility: Carbon hydrogen cleaning agents, along with most stamping oils, rust proof oils, and machining oils, are petroleum fractions. Based on the principle of similar solubility, the effect of carbon hydrogen cleaning agents on cleaning these mineral oils is better than that of halogenated hydrocarbons and water-based cleaning agents.
4. Volatile without residue: Carbon hydrogen cleaning agents are very pure refined solvents that can completely evaporate at room temperature and heating without residue.
5. Environmentally friendly: Carbon hydrogen cleaning agents can naturally degrade, and the cleaning waste can be incinerated in coal-fired or oil fired boilers. The main products of incineration are CO2 and water, which do not pollute the air. Carbon hydrogen cleaning agents do not contain chlorine and have a zero ozone depletion coefficient.
6. Short term rust prevention function: Workpieces cleaned with hydrocarbons have a certain rust prevention function, with a rust prevention time of ≥ 48 hours.
Quickly becoming an industrial service industry covering various fields of the national economy, including petroleum, chemical, energy, power metallurgy, construction, machinery and electronics, transportation, aerospace, etc., including technical categories such as chemical cleaning, physical cleaning, microbial cleaning, etc. With the continuous introduction of various new technologies and mechanical equipment, the technological progress of the cleaning industry has also developed rapidly, providing great assistance to industrial enterprises in energy conservation and consumption reduction, extending equipment service life, improving product quality, reducing pollution emissions, and making huge contributions to the development of industrial economy.
All people related to industrial cleaning can participate, jointly build and share, and benefit together. Form a new development model of resource sharing and resource sharing, and work together to promote the rapid and healthy development of China's industrial cleaning industry. In order to ensure the quality of subsequent processes and the entire product processing, many industrial products use laser cleaning to remove oil stains, dust, rust, or other residual solvents, adhesives, and other debris from the product surface before electroplating, spraying, welding, phosphating, integration, and packaging.
Compared with laser cleaning, traditional cleaning methods include ultrasonic cleaning, chemical cleaning, and mechanical cleaning. Usually, sandblasting, scraping, wiping, and other methods are used to remove surface contaminants. Chemical cleaning uses chemical cleaning agents to remove surface attachments through spraying, rinsing, soaking, or high-frequency vibration, while ultrasonic cleaning requires parts to be completely immersed in the cleaning agent and uses high-frequency vibration of ultrasonic waves to remove dirt.
The principle and method of laser cleaning: The principle of laser cleaning technology is to use a high-energy density laser beam to irradiate the surface of the workpiece to be cleaned, causing the oil stains, rust spots and other substances on the surface to evaporate or fall off instantly. It can quickly and effectively remove the attachments or excess layers on the workpiece, achieving the purpose of cleaning the workpiece. Laser cleaning is a cutting-edge technology based on the interaction effects between laser beams and other substances.
Compared with traditional cleaning methods such as mechanical cleaning, chemical corrosion cleaning, solid-liquid mixed strong impact cleaning, and ultrasonic high-frequency cleaning, laser cleaning has significant advantages such as high efficiency, fast speed, and low cost. Moreover, the heat load and mechanical force generated on the workpiece are very small, and it will not cause damage to the workpiece. Moreover, waste can be recycled in a timely manner, which will not pollute the environment and harm operators. It can also achieve remote automatic remote cleaning.



The characteristics of laser cleaning: The laser beam has high density, high coherence, high directionality, and monochromaticity. In the process of laser cleaning, the following characteristics of laser are mainly used: 1. Laser beams can achieve high concentration of light energy in time and space, and focused laser beams can generate high energy around the spot, causing dirt to quickly evaporate, evaporate, or peel off. 2. The scattering characteristics of laser beams are small and the directionality is stable. Through the focusing system, the laser beam can form light spots of different diameters as needed.
By controlling the laser beam spot with different diameters, the energy density of the laser can be adjusted to cause changes in the dirt during heating. When the expansion force of dirt is greater than the adsorption force of dirt on the substrate, the attachment will separate and fall off. 3. Laser cleaning beams can generate high-frequency ultrasonic waves on solid surfaces, resulting in mechanical resonance and rapid breaking and detachment of dirt. Metal cleaning agents are widely used in industrial production.
They are commonly used for surface degreasing and descaling before and after metal processing, as well as for cleaning processes before assembly or packaging of finished products. In the electronics industry, it is also necessary to use cleaning agents to remove harmful residues after PCB soldering. In addition, metal cleaning agents are commonly used for the maintenance of mechanical equipment. In the field of metal surface treatment, cold-rolled steel plates or metal workpieces require anti-corrosion treatment during storage, that is, the surface is coated with grease. Therefore, degreasing and surface cleaning are required before use.
The purpose of metal degreasing cleaning is to remove grease from the metal surface and provide a clean metal surface for electroplating, coating, or other metal protection treatments. Therefore, the selection and cleaning effect of cleaning agents are not only related to the performance and quality, corrosion resistance, and service life of metal workpieces, but also to energy consumption and environmental protection, directly affecting the smooth progress of various processes in the production process. Solvent based metal cleaning agents are gradually being replaced by semi solvent and water-based metal cleaning agents.
Water based metal cleaning agents are used to clean oil, grease, and wax on metal surfaces with the help of surfactants, alkaline detergents, complexing agents, solvents, corrosion inhibitors, defoamers, and solubilizers through functions such as wetting, emulsification, permeation, dispersion, and dissolution. Water based metal cleaning agents are detergents composed of water as the solvent, composite surfactants as the main cleaning agent, and various additives.
