Sectors that require sensitive cleaning services

Regardless of the industry, all companies want to run a safe operation and minimize production downtime. Even microscopic contamination of manufacturing equipment and parts - dirt, lime, corrosion, debris and corrosive contaminants on the components - can affect its performance. Equipment and parts become unreliable, prone to early wear and deterioration. This strikes an organization's productivity and efficiency.

As a result, it is a critical function when it comes to getting the most value from precise cleaning, production and maintenance. It is one of the most critical, time-consuming, costly and risky tasks for any organization. EUROLAB offers precision cleaning services for parts, assemblies, pressure vessels, pipes, heat exchangers and various other equipment.

However, management in the aviation industry should focus on the safety and quality of the aircraft and related components, including:

  • Landing gear
  • Jet engine assemblies
  • Aircraft bodies and structural components
  • Brake groups
  • Oxygen systems
  • Hydraulic and mineral oil systems

Whether you need to clean large structures, pipes or other components, proper cleaning system and expertise will determine your success.

Many small, medium and large businesses need precise cleaning services for critical processes and applications. These companies cover a wide range of industries, including:

  • Automotive
  • Telecommunication
  • Consumer electronics
  • Hospital equipment
  • Smart grid, solar panel and other clean energy systems
  • Health information systems

Depending on the industry, each component is different and requires special cleaning techniques, testing and cleaning verification.

What are the other sensitive cleaning methods?

Companies should identify the appropriate cleaning solution based on various factors, such as workpiece type, part geometry, type and degree of contamination, processing status, and degree of cleaning required by the customer.

The cleaning solution should be effective enough for the task and remove a wide range of contaminants. With the use of numerous cleaning techniques and different cleaning procedures, companies can achieve the desired level of cleaning for almost any cleaning task. EUROLAB technicians and engineers use a range of precision cleaning tasks, including:

Aqueous Cleaning - This method is for parts that need to be wet for a long time. It uses water treated with deionization or reverse osmosis and combined with detergent and surfactants. The process is effective for various soils, compatible with most materials and has a wide range of chemical options. The eco-friendly nature of the aqueous cleaning offers an attractive solution to achieve the desired level of cleaning.

Immersion Cleaning - For complex geometry parts such as undercuts and blind holes, parts need to be flushed in solvent work. After the component is immersed in the solvent, the chemical effects of the solvent remove the contaminants. Some applications use other procedures, such as immersion and ultrasound.

Ultrasonic Cleaning - In many sensitive cleaning processes, aqueous, semi-aqueous and solvent-based cleaning systems and ultrasonic cleaning are used with detergents. The technique, which works particularly well for complex parts, uses special frequencies or sound waves to clean particles and soil on a surface. Ultrasonic cleaning provides decontamination at almost microscopic levels, because ultrasonic shaking uses high frequency sound, which creates small bubbles that release and release significant amounts of energy in the cleaning fluid. As a rule, higher frequencies can remove thinner particles.

On the other hand, a very low frequency can break up sensitive materials or cause undetectable microcracks. Ultrasonic cleaning provides an effective method for cleaning teeth, rough surfaces, blind and drilled holes, sharp inner corners and similar cavities that other industrial cleaning methods cannot reach.

High Pressure Spray Cleaning - High pressure spray cleaning, often used with detergents or surfactants, uses the kinetic energy of the water jet to spray particles and dirt from a surface. The chemical effect of the cleaning medium partially removes or emulsifies the dirt and the high kinetic energy of the jet sprays the remaining dirt from the part. The quality of cleaning depends on the shape and configuration of the nozzles and the spraying power. The pressure used for cleaning depends on several factors, such as the type of material and contaminant.

Wipe Cleaning - This method works for sensitive surfaces that cannot withstand aggressive cleaning solutions. Typically, it uses special swabs or lint-free and particle-free wipes dipped in solvent or deionized water.

Injection Flood - With this method, the operator fills the part with cleaning fluid while the part is rotating. A jet generates currents and turbulent speed through pipes, blind holes, cavities and recesses. Fluid removes contaminants from equipment or parts. This method offers flexibility and does not require any adjustment to target each part. This technique removes particles and produces an excellent level of cleaning for components of all sizes and various shapes.

Vacuum Cooking - This procedure uses vacuum cooking to remove contamination of sensitive equipment, especially in pores. It reduces the degassing rates of instrumentation that may be sensitive to molecular contamination to acceptable levels.

CO2 Cleaning - This cleaning process is widely used for precise cleaning and surface preparation for high-tech components, optical devices, sensor cutting tools and aerospace parts.

Some sensitive cleaning services use two or more cleaning methods to achieve the level of cleanliness required for compatibility or to meet customers' specifications. EUROLAB provides the following services for cleaning in-process parts and finished products.

Descaler and Acid Cleaning of Iron and Carbon Steels - Whether for the initial use or restoration of the original surface condition of a component, EUROLAB has many years of experience in process development and increasing its expertise in acid use. We have an expert team for descaling, rust removal or removing embedded iron and unwanted oxides from metal surfaces. Depending on the amount and type of lime available, other pollutants and your project requirements, EUROLAB uses formulated solutions of acid cleaners. These solutions remove oxide, oil, grease and other contaminants to clean iron and steel. When necessary, we combine acid solutions with a wetting agent and detergent. We also use other techniques such as dipping, spraying, paste, washing and passivating to achieve precise cleaning results that meet our customers' expectations.

Commercial Oxygen Cleaning - Some customers may request that the equipment commonly used for O2 service be cleaned with oxygen. Exposure of the system to oxygen or oxygen-enriched service requires rigorous cleaning to remove surface contaminants such as oils, greases and particles. Although the customer does not specify a specific cleaning protocol, it typically requires a commercial cleaning for the oxygen service. When choosing a cleaning procedure, EUROLAB uses three commercial specifications to select process and acceptance criteria for oxygen cleaning: ASTM G 93-96, Compressed Gas Association (CGA) Brochure G-4.1 and CGA Brochure G-4.8.

Hydraulic Cleaning and Testing - EUROLAB provides the expertise required to clean and test hydraulic components and assemblies, including regulators, valves, pistons, accumulators, transducers, actuators, piping and piping, control and distribution manifolds, and servos and storage tanks. In our Class 10.000 cleanroom we use aqueous detergents, a large number of compatible solvents or system hydraulic test fluids, 50.000 psi (DI water or hydraulic fluid) and 20.000 psi (GN2) proofing and leak testing of components or assemblies. You can work with us to do your hydraulic cleaning and analysis in our clean room to eliminate concerns about on-site environmental or safety issues.

Maintenance and Repair Services - As a full service provider, you can count on us when you need additional technical support. We can overhaul and repair parts and assemblies before delicate cleaning. We can also clean detailed components and install them in our Class 10.000 clean room. EUROLAB will repair, overhaul, test, and precisely clean and regulate your regulators, pumps, valves, filter units, gauges, control / drain panels or other equipment. If you choose to do the job, you can either rent or rent our clean environment and run a pressure or leak test according to your needs.

Ultrasonic Cleaning - Our ultrasonic tanks range from 12 inches square and 8 inches deep to 48 inches square and 48 inches deep. EUROLAB technicians take into account factors such as part size, configuration and material type to determine the appropriate tank size, converter power output, frequency and cleaning solution to target specific pollutants and customize the cleaning process. Depending on how clean you want the part, we have the experience and expertise you can trust.

Total Hydrocarbon Analysis - This method measures the total amount of volatile and non-volatile residues in the waste water solvent sample to determine its cleanliness. Our technicians typically use Fourier Transform Infrared Analysis (FTIR) and Infrared Analysis (IR) to determine the total amount of volatile and non-volatile deposits remaining in the clean part. When you need to know the total amount of residue that can remain on the part after cleaning, total hydrocarbon analysis is the preferred technique.

Gas Sampling - Often, the technician cannot insert liquid into a clean system to determine the amount of loose particles remaining. With the gas sampling technique, the technician supplies a known certified gas to a pipe or pipe system at a given pressure and flow rate. The discharged particles are collected in a Millipore filter holder or gas bomb, which the technician can analyze for the number of particles.

Dryness Verification - Solvent residue or latent moisture can corrode the cleaned part in service or warehouse. EUROLAB uses a number of drying methods and follows the dew point verification to determine that the remaining moisture is at an acceptable level. Gas detection verification ensures that hydrocarbon or halogen residues meet the required criteria.

Sealing and Packaging for Preservation - EUROLAB takes sealing integrity and packaging performance seriously to keep contaminants and moisture out. The final stage of cleaning requires primary and secondary obstacles. Some components may require a third level of protection. We use a variety of packaging materials, such as Nylon, Aclar and polyethylene films, that have the same or better cleaning level than the actual parts they protect. EUROLAB can also accommodate customers with extra protection features. This requires additional steps in the sealing and packing process, such as vacuum packaging, cleaning the interior of parts and barriers with certified clean and dry nitrogen or adding dryers and moisture indicators to the final package.

Verification and Analysis

Cleaning verification is a critical stage of the sensitive cleaning process. EUROLAB uses three methods to meet even the strictest cleaning requirements:

Visually Cleaning - After pre-cleaning the parts, we do a visual inspection and an ultraviolet (black light) inspection to verify successful cleaning. Throughout the cleaning process, our technicians inspect accessible space and spaces for any contaminants, including:

  • Trap of foreign bodies
  • Rust, rust
  • Kir
  • Scale on welded surfaces
  • Fading
  • Su
  • Solvent

All parts must be visually inspected before the final cleaning. To verify the final cleaning of the components, most EUROLAB customers require us to apply quantitative analysis techniques. We typically use particle count analysis and non-volatile residue analysis to determine how clean the parts are.

Particle Count Analysis - We do this in our clean room. Our technician removes and collects a predetermined volume, such as water or solvent, depending on the amount of wet surface area of ​​the piece being cleaned. We use many industry and military standards and specifications that have been written specifically to address sampling and collection protocols. These include sampling and collection methods, the amount of fluid to be collected, and quantitative acceptance criteria for a particular level of cleaning.

Non Volatile Residue (NVR) Analysis - NVR analysis, typically the final step in cleaning, determines the amount of non-volatile residue or film that remains on the part after cleaning. To ensure that we only measure residue or film, the technician usually uses the gravimetric technique that filters particles from the sample before the wastewater sample test.

Most sensitive cleaning processes use NVR analysis of solvents to determine the compatibility of clean parts with liquid or gaseous systems and other service environments sensitive to organic film residues.
