Industrial cleaning agent product classification

In the precision processes of modern industrial production, industrial cleaning agents play an indispensable role. This kind of chemical preparation specially developed for the surface dirt of equipment, parts and products can efficiently remove stubborn pollutants such as oil, rust, carbon deposits, limescale, etc., and its performance directly affects production efficiency and product quality. According to different chemical properties, application scenarios and cleaning processes, industrial cleaningagents can build a multi-dimensional classification system, which will be elaborated below.

1. Classification framework constructed according to chemical properties

1. Water-based cleaners: A balanced choice between environmental protection and safety

Water-based cleaning agents are based on water, and a stable system is formed by compounding functional ingredients such as surfactants, cleaning aids, and corrosion inhibitors. Its core advantage is environmental compatibility – the biodegradation rate is usually more than 90%, which is much higher than that of organic solvent-based products, and it is non-flammable and explosive, significantly reducing the health hazard to operators.

In terms of decontamination mechanism, this type of cleaning agent mainly relies on the emulsification and dispersion of surfactants to decompose hydrophilic dirt, and the removal efficiency of water-soluble grease and dust can reach more than 95%. However, when dealing with hydrophobic contaminants such as high-viscosity mineral oils, the effect needs to be improved by heating to 60-80°C or extending the cleaning time. Since it uses water as the medium, it can be rinsed directly with clean water to remove residues after cleaning, making it particularly suitable for residue-sensitive scenarios such as electronic components and precision mechanical parts. At present, the use rate of water-based cleaning agents in the spray cleaning line of auto parts and the PCB board cleaning process of electronics factories has exceeded 70%.

2. Semi-water-based cleaning agents: optimization of efficiency and cost

Semi-aqueous cleaning agents are the product of the fusion of water-based and organic solvent technology, usually composed of 30%-60% organic solvents (such as glycol ethers, terpenes), surfactants and deionized water. This formulation design offers a dual advantage: it dissolves grease-based dirt as quickly as organic solvents, and disperses inorganic pollutants through aqueous components, resulting in 20%-30% higher removal of mixed dirt than a single system.

Compared with pure organic solvents, its volatility is reduced by more than 50%, and the flash point is generally higher than 60°C, greatly improving the safety of storage and use. In terms of cost, it is between water-based (about 8-15 yuan/liter) and solvent-based (about 20-50 yuan/liter), which is especially suitable for precision optical instruments, aerospace parts and other scenarios that require high cleaning accuracy and have limited budgets. Application data from an optical lens factory shows that the use of semi-water-based cleaners has increased the cleaning pass rate from 82% to 97%, while reducing the unit cost by 18%.

3. Organic solvent-based cleaning agents: professional choice for efficient stain removal

Cleaning agents with organic solvents such as hydrocarbons, chlorinated hydrocarbons, and alcohol ethers as the main body show strong oil dissolution ability by virtue of similar miscibility principles. Experimental data show that the extreme pressure lubricating scale generated by machining is removed 3-5 times faster than water-based products, and can be completely dissolved within 30 seconds at room temperature.

The rapid volatilization nature of these cleaning agents (boiling points below 80°C in some products) eliminates the need for washing and is particularly suitable for cleaning moisture-sensitive electronic components. However, the safety risks cannot be ignored: the occupational exposure limit for benzene solvents is only 50mg/m³, and most of them are flammable and explosive (flash point below 28°C). At present, it is mainly used in high-end manufacturing fields such as aero engine core components and semiconductor wafers, and needs to be equipped with explosion-proof cleaning equipment and exhaust gas recovery systems when used.

2. Professional categories divided by application scenarios

1. Metal cleaning agent: precise cleaning suitable for the material

Customized formulation of metal cleaning agents for the chemical properties of different metals: the special type for steel adds corrosion inhibition ingredients such as sodium nitrite, which can form a protective film of 2-5μm after cleaning, and the rust prevention period of salt spray test is more than 72 hours; The special formula for aluminum products adopts a weak alkaline system (pH 8.5-9.5) to avoid pitting corrosion; copper cleaning agents such as benzotriazole are added to prevent surface oxidation and discoloration.

In terms of decontamination ability, the ratio of surfactant and chelating agent can be adjusted to achieve targeted removal of different pollutants such as cutting oil, oxide scale, and welding slag. After using a special metal cleaning agent in an automobile transmission factory, the amount of oil stain residue after cleaning the parts was reduced from 50mg/m² to less than 5mg/m², and the assembly qualification rate increased to 99.5%. It is widely used in machining cleaning between processes, degreasing before and after heat treatment, surface pretreatment before spraying, etc.

2. Optical Glass Cleaner: The guardian of optical performance

The core technology of optical glass cleaners lies in balancing decontamination power and safety: nanoscale surfactants (particle size 5-20nm) are used to efficiently emulsify fingerprint grease, while abrasive additives such as colloidal silica are added to remove polishing powder particles below 0.1μm. Its low-foam formula (foam height below 10mm/5 minutes) ensures that the cleaning effect is not affected by the foam wrap during ultrasonic cleaning.

Protection of optical properties is a key indicator: the refractive index of the cleaning agent should be controlled between 1.45-1.50 to avoid residue leading to a decrease in lens transmittance; The pH level is strictly maintained in the neutral range of 6.5-7.5, and after a 48-hour immersion test, there are no signs of corrosion on the glass surface. It is mainly used for precision cleaning of optical components such as camera lenses, laser lenses, and LCD panels, and the product defect rate has dropped from 3.2% to 0.5% after a lens manufacturer has applied it.

3. Electronic cleaner: the guarantor of electrical safety

Electronic cleaning agents must meet strict insulation requirements, with a volume resistivity of ≥ of 10¹²Ω cm and a dielectric strength ≥ 30kV/mm to ensure that the electrical properties of electronic components are not affected after cleaning. Its rapid volatilization formula (drying time < 30 seconds) avoids the risk of short circuit due to moisture residue, and has no swelling effect on plastics such as ABS and PC (weight change rate <0.1%).

Develop special formulations for different electronic components: PCB board cleaning agent contains rosin solubility to remove flux residue; Connector cleaner adds lubricating ingredients to reduce plugging and unplugging wear while decontaminating. The chip cleaning agent uses ultra-pure solvent (99.99% purity) to avoid particle contamination. In 5G base station equipment maintenance, specialized electronic cleaning agents can reduce equipment failure rates by more than 40%.

4. Plastic cleaner: Gentle cleaning with compatible materials

The formulation design of plastic cleaningagents needs to take into account diversity: for non-polar plastics such as PE and PP, hydrocarbon solvents are used to enhance the solubility of oil stains; For polar plastics such as ABS and PMMA, alcohol ether solvents are used to avoid stress cracking. Specially added plasticizer stabilizer can prevent the plastic from turning white and brittle during the cleaning process.

Functional diversification: the degreasing type can remove the residue of injection molding release agent; The adhesive removal type contains special ester components, which can soften the label adhesive layer; The anti-mold type adds preservatives such as isothiazolinone to extend the shelf life of the cleaned plastic parts to 12 months in a humid environment. It is widely used in the cleaning and treatment of plastic shells of home appliances, plastic parts of medical devices, packaging containers, etc.

3. Special preparations designed according to the cleaning process

1. Spray cleaning agent: the core additive of the efficient assembly line

Spray cleaner is designed for high-pressure spray systems (pressure 0.3-0.8MPa) and its low foam characteristics (foam dissipation time < 10 seconds) prevent nozzle clogging; The special wetting agent formulation allows the liquid to spread over 5cm/s on the metal surface, ensuring adequate cleaning of crevices.

Concentration stability is critical to continuous assembly line operation: by adding a buffer, the concentration change rate of the working fluid < 5% after 8 hours of continuous use. The application of a spray line at an auto parts factory showed that a specialized cleaning agent increased the daily throughput of a single line by 20% while reducing chemical consumption by 30%. It is mainly used for continuous cleaning of large quantities of parts such as engine blocks, wheel hubs, and metal sheets.

2. Ultrasonic Cleaners: Solutions for microscopic cleaning

Ultrasonic cleaning agents form a synergistic effect with cavitation effect: the active ingredients in the formula can reduce the surface tension of the liquid to less than 25mN/m, and enhance the bursting force of the cavitation bubbles; The added rust inhibitor can evenly adhere to the surface of the inner cavity of complex parts under the action of cavitation, solving the blind spot problem of traditional cleaning.

Thermal stability is a key indicator: within the ultrasonic cleaning temperature range of 40-80°C, the active ingredient decomposition rate <3%, ensuring a consistent decontamination effect. For parts with micropores of 0.1mm, the amount of oil stain residue can be controlled below 1mg after cleaning. It is widely used in the deep cleaning of parts with complex structures such as precision bearings, fuel injectors, and surgical instruments.

3. Soaking Cleaner: Ideal for flexible treatment

The soaking cleaning agent uses a mild chemical system (pH 6-10) and has a corrosion rate of 0.01 g/m²·h < 0.01 g/m²·h, making it particularly suitable for vulnerable materials such as aluminum and magnesium alloys. By adjusting the concentration (5%-20%) and temperature (ambient to 80°C), it can accommodate different cleaning needs from light oil stains to heavy carbon deposits, with a maximum soak time of up to 72 hours without damaging the substrate.

After a mold shop used a special immersing agent, the cleaning time for complex cavities was reduced from 8 hours to 2 hours, while the surface roughness of the mold remained the same. It is mainly used for non-continuous cleaning of small tools, precision molds, maintenance parts, etc., especially suitable for cleaning scenarios with small batches and many types.

epilogue

The classification system of industrialcleaning agents reflects the development trend of refinement in the industry - from general to special, from single function to multi-functional integration. Choosing the right cleaning agent requires comprehensive consideration of multiple factors such as pollutant types, substrate characteristics, and process conditions, and achieving efficient, safe, and environmentally friendly cleaning goals through scientific matching. With the advancement of intelligent manufacturing, cleaning agents will form closer synergy with cleaning equipment and process parameters, promoting the development of industrial cleaning technology in the direction of digitalization and precision.
