But what are biologics? Instead of conventionally removing pollutants, a biological system uses bacteria substances upon their contact with the waste stream. By harnessing this power for nature, metal finishing manufacturers can remove key compounds such as: BOD/COD, macronutrients like nitrogen and phosphorus compounds, and micronutrients like trace metals and minerals.

And there鈥檚 several variations that manufacturers can use and tailor to their needs鈥攖hese masses of bacteria either in a fixed film or a conventional activated sludge system. While this method only acts as a final polish, working at the part per billion level, it鈥檚 a great way to keep pace with increasingly stringent regulations on pre-treat systems.

In surface treatment, it’s very common to use filtration on the paint line when you are doing an e-coat.聽 You use membranes to filter the paint pigment. 艳照门视频 has AquaEase Infinity聽 鈥� a membrane filtration system to remove oil from the cleaner.

When you’re talking about membranes, there are four different processes:

1. Reverse osmosis (RO). This is the most used in the plating industry and wastewater operation.聽 It’s very common to separate ions, aqueous salt, and fruit juice concentration. With this process, normal pores sizes: are 0.001icrons.
2. Nanofiltration (NF). This process can be used for softening and demineralization of water, taking dyes from some processes, or filtering sugar from processed food.聽 This is a really low number of pore sizes 鈥� 0.001-0.01 micros.
3. Microfiltration(MF). This is the process that is normally used to remove solids suspended in water, wastewater, clarification process, and also used to filter paint and resins. Also to remove bacteria The measurement for pores is usually 0.1-1 micron.
4. Ultrafiltration(UF). This is the size of the membrane pores used on the Aquaease Infinity. 0.01 to 1.0 microns. With ultrafiltration, you can select what you would like to remove, for example, some proteins from food, and emulsified oils captured from industrial cleaners without stripping off the surfactants or builders from the process.

Ultrafiltration is exactly where 艳照门视频 can help you. With AquaEase Infinity鈥� a membrane filtration system that traps all of the emulsified oils allowing the good cleaner to pass through.

A wastewater operator should receive training for more than just wastewater treatment. This person should receive first responder and spill response training. They should know how to handle if the plating line hexavalent chrome spills and hits wastewater. They know what to do and how to correct that problem, so you don’t have a pass-through event. They receive maintenance training, so they know how to rebuild pumps, and they receive plumbing training so they know how to pipe properly and how pipes should flow and how to repair leaky pipes. Lastly, IT training is important so they know how to handle the PLC or SCADA unit that your system may be operating under.

If 90% of the time they look like they’re not really doing anything, you can trust and believe they are. They’re going through a checklist in their head. They’re listening to the pumps to make sure that they’re pumping properly, because you can tell a difference in the sound pumps make when a pump doesn’t work correctly. They’re smelling the air to make sure that the air smells the way it normally does, because if there’s a spill on a line the air quality in wastewater changes.

A best practice is to give an operator a checklist to run through every hour 鈥� make sure the floc is forming, check the pH, make sure the chemicals are feeding right and that there are chemicals to last. This ensures the system has eyes on it a regular interval and helps prevent pass through events.

This person can also help your organization understand why wastewater works with your manufacturing processes.聽 For example, we had one customer who was able to calculate that for every gallon of wastewater that left the plant, 10 finished parts were produced.聽 For those 10 finished parts they were able to calculate cost of manufacturing them, what waste treatment cost was and what the profit was.

So, what do you do?聽 Do you make the investment, or can you work with what you have and even find cost savings and reduce chemical consumption?

In this case, our experts were able to help the manufacturer identify the proper PLC (Programmable Logic Control) unit that will control pH probes, pumps, water transfer pumps and chemical feed pumps.聽 This change is going to take a less hands-on human compatibility to run it because with the flip of a switch the computer’s going to run it.

Through a combination of virtual visits and being tank side, we took this manufacture from a very basic wastewater system with barely any control at all to a flow through system that鈥檚 now robust enough to double wastewater flow capacity and still meet the metal removal goals.

The next step is to add that programmable logic, so someone doesn鈥檛 have to be standing there turning pumps on and off. Or if they forget to turn off the chemical dose pump and they come in the next morning, they’re out of chemistry, now they can’t run. A computer will do that for them.

Within ASTM, several methods and rating schemes exist to objectively evaluate various aspects of paint performance, ranging from adhesion properties to resistance against corrosion. These methods frequently involve the use of humidity and salt spray chambers, calibrated to respective standards, in order to expedite the simulation of environmental conditions within a relatively short timeframe. Humidity testing (ASTM D2247) is a milder version of accelerated testing, where a continuous, stable water fog is applied to replicate humidity resistance. Alternatively, more aggressive assessments utilize salt-based solutions, either neutral or acidic, to replicate corrosive environments. Among these, neutral salt spray (ASTM B117) stands as the predominant approach for evaluating paint performance.

Across multiple standards, test specimens can be prepared using panels containing substrates, pretreatments, & paint applications representative of the actual part being evaluated. Once prepared, these panels can be evaluated via several methods, often integrating multiple standards to comprehensively measure specific performance aspects. Routine types of testing include:

• First Rust Evaluation: A straightforward approach involving the assessment of a painted part or panel within an accelerated environment until initial indications of rust manifest. This method can also be utilized to evaluate the tenacity of the paint itself.
• Creep from Scribe: This method consists of a set of panels scored with centerline scribe that are concurrently subjected to an accelerated chamber at periodic intervals. After exposure, panels are evaluated by scouring perpendicular to the scribe, with the average width of paint removed being quantified.
• Cross-Hatch Testing: This technique involves a series of parallel scribes intersecting another perpendicular set of scribes. These scribes can be assessed within an accelerated environment, or immediately tested by applying and removing tape over the intersectional area to evaluate potential paint removal.

Regardless of the chosen methods or standards, it is important to acknowledge that these tests function as relative indicators of performance and durability. Metrics and ratings often depend on customer specifications. Given the multitude of factors influencing performance 鈥� from surface geometry and pretreatment morphology to quality of paint applied 鈥� parameters can be tailored to the part and its intended application.

• Is the rust preventative being applied to the part during an in-process step or is this the final step in the production process?
• Will the part be stored indoors or outdoors?
• How much corrosion protection is required?
• Are there specific customer or military specifications that need to be met?
• What type of finish is desired on a part after treatment (oily, dry-to-touch)?
• How is the rust preventative being applied (immersion, spray, brush, etc.)?

Customers that need short-term temporary in-process rust protection between manufacturing steps, a Metal Guard 800 series water based rust preventative is typically preferred.聽聽 For example, parts that need rust protection prior to painting, plating, or powder-coating would benefit from this type of rust preventative.聽 Water based rust preventatives do not contain oil, therefore the parts are easily cleaned and do not contaminate the pretreatment processes on the paint or plating lines.聽 However, water based rust preventatives only provide a few days of rust protection.

For the cost-conscious customer wanting more rust protection than what is provided by a water-based product, a water-soluble or water emulsifiable oil such as Metal Guard 320 would be recommended.聽 These products are very versatile and are used heated, typically around 140^o F. They are diluted 5%-25% by volume in water, depending on the amount of rust protection desired, and the level of oiliness the customer prefers on the part surface.聽聽 These products typically provide 48-96 hours (about 4 days) of ASTM B-117 salt spray protection over a black oxide finish.

The best protection is provided by a water displacing rust preventative such as our Metal Guard 400 and 500 series of products.聽 These products are considered long term indoor rust preventatives and differ based on the type of final oil film left on the surface.聽 If the customer desires a drier final finish, they will use Metal Guard 450, however they would be accepting a reduction in corrosion protection in order to get that drier finish. 聽Conversely, if the customer desires up to 200 hours (about 1 week) rust protection, they will use Metal Guard 560, but the final finish will be oilier.

Customers that need outdoor rust protection will use Metal Guard 900, which is a viscous thixotropic liquid that forms a soft easily removed barrier to protect bare steel from corrosion in outdoor environments. A customer using Metal Guard 900 would apply this material via spray, immersion, or brush, and they can expect up to two months of outdoor rust protection.

1. What is the contamination? What kind of oil are you using that will need to be removed?
Do a deep dive into the process, look at the SDS of the products currently used to determine the oil that you are working with. Light oil or chlorinated/sulfonated oils are heavy and there are different methods depending on the oil. Knowing exactly what oil it is determines the type of cleaner used. Understanding the oil to be removed, will be easier to plan on what will be the best type of cleaning and equipment to be used.

2. What is the part you are treating?
Geometry and alloy determine the process and the size of the chamber and/or tanks needed. Without the proper process in place residual contaminates 鈥渂urn鈥� into the surface during the heat treat step 鈥� causing an increase in scrap and dissatisfied customers.

3. Polar or Non-polar?
This determines the effectiveness of the chemistry you use on various contaminants. Solvent cleaners such as chlorinated, hydrocarbons and modified alcohols are used on non-polar and water soluble are effective on resins and stearates. Aqueous cleaners such as alkaline and acidic cleaners are water soluble or polar and effective against most contaminants.

4. What is the current process?

The post Considerations for Proper Cleaning for Heat Treating. appeared first on 艳照门视频.

Trichloroethylene has long been hailed as a workhorse in the industrial realm, demonstrating exceptional cleaning and degreasing capabilities. Despite its effectiveness, TCE is not known for being environmentally friendly, making it a complex chemical to work with. However, it has been a staple in industrial operations for generations.

October 2023, one of the largest TCE manufacturers decided to cease production, resulting in a 50% reduction in global supply. This sudden drop in availability triggered a surge in prices and a scramble for alternatives, forcing businesses to reevaluate their solvent choices and practices.

In the wake of the shortage, confusion arose as businesses began substituting one TCE product for another without understanding the crucial differences. Not all trichloroethylene is created equal, as it requires stabilization for proper functioning. Unstabilized variants, often sourced from Asia, posed a significant threat, as they could turn acidic under stress, leading to machine degradation and potential damage.

Recognizing the need for a strategic shift, industry players have pioneered the development of double-stabilized solvents. The objective is no longer to replace existing solvents but to equip businesses with the tools to maintain and stabilize their current supplies. This paradigm shift marks a departure from the traditional volume-based industry approach to a more sustainable and intelligent solvent management strategy.

With the scarcity of TCE in the market, businesses are urged to adopt a proactive stance. Rather than resorting to the conventional practice of dumping and refilling machines with fresh solvent, the emphasis is now on testing and ensuring the viability of the existing solvent. This allows for restabilization, extending the lifespan of the solvent and reducing the need for constant replenishment.

The trichloroethylene shortage has catalyzed a transformation in the industrial cleaning and degreasing landscape. Businesses are compelled to be more strategic and resourceful in their solvent management practices, prioritizing stability and sustainability over sheer volume. As the industry navigates this paradigm shift, collaboration, communication, and innovation will play pivotal roles in ensuring a resilient and efficient future for industrial cleaning processes.

Understanding the Contaminant:
The first step in choosing an effective cleaning process is identifying the nature of the contaminant. Whether it’s a chlorinated oil, a viscous Cosmoline type substance, or light mineral oils, knowing what you’re dealing with is paramount. The ability of a cleaning agent to dissolve or remove the contaminant depends on its composition and the interaction between polar and non-polar constituents.

Chemistry Matters:
Manufacturers and suppliers play a crucial role in determining whether their chemistry can effectively dissolve or remove specific contaminants. This pivotal aspect sets the stage for the success of the cleaning process, he chemistry must be compatible with the contaminant for the cleaning process to be successful.

Boiling Point and Solvent Aggressiveness:
The boiling point of a solvent is a critical factor in the cleaning process. Additionally, the kauri-butanol value indicates how aggressive a solvent is. These characteristics influence the solvent’s ability to dissolve contaminants effectively. A lower surface tension facilitates the solvent’s penetration into tight spaces, making it easier to flush out contaminants from semiconductors or blind holes.

Considerations for Application Techniques:
Choosing the right cleaning technique involves weighing options such as ultrasonics, flushing, or spraying. The decision depends on the specific cleaning requirements and the nature of the contaminants. The conversation emphasizes that solvents may not always be the optimal choice, with water and surfactants proving effective in certain scenarios. Applicators should carefully evaluate their needs, considering factors like floor space, equipment setup time, and efficiency.

Solvent vs. Aqueous Systems:
The debate between solvent and aqueous systems revolves around practical considerations. Solvent systems offer a plug-and-go solution, requiring minimal floor space and rapid readiness. On the other hand, aqueous systems may demand more extensive setups, involving pre-rinse, cleaning, and drying baths, potentially limiting their viability based on available space.

Water, a Double-Edged Sword:
Aqueous systems introduce an additional challenge 鈥� the management of water and its contamination. Contaminants must be removed from the water before disposal, incurring additional expenses. In contrast, solvents can be recycled almost infinitely, provided proper maintenance and stability are upheld. This factor makes solvents an attractive option for those looking to minimize operational costs and environmental impact.

Choosing the right cleaning process involves a careful consideration of various characteristics, from solvent chemistry to application techniques and system practicality. Understanding the nature of contaminants and evaluating the specific needs of the application are key in making an informed decision. While solvents offer advantages in certain scenarios, water-based systems can be equally effective with their own set of considerations. Ultimately, finding the perfect balance between efficiency, cost-effectiveness, and environmental impact is the key to successful cleaning processes in diverse industrial applications.

Organic soils are the more commonly acknowledged contaminants in coating applications. These can include previous rust inhibitors, machining or stamping fluids, lubricants, and buffing or polishing compounds. In addition to having an effective cleaning process to remove these soils from the parts鈥� surface, we also want to ensure that are removed in a manner that prevents them from being carried over into subsequent process tanks. Cross-contamination, especially from organic-based products, can cause many frustrating and costly problems down the line. With cleaners, we tend to break them down into two camps: emulsifying and oil-splitting 鈥� each with its own pros and cons. Emulsifying cleaners are great in tying up the removed organics into the solution which mitigates the risk of them being carried into other process tanks, these are particularly effective in barrel processing. Oil-splitting cleaners shine for parts that are heavily contaminated. Since they are able to easily split the organics from the cleaner solution, they are easily separated and promote exceptional bath life for the cleaner.

Conversely, inorganic soils are also important to address when considering effective cleaning and activation steps. These include surface oxidation (rust), scale from welding or heat treating, carbon or smuts, and other various metallic compounds. Often, caustic cleaners with the right chelating package can address many of these issues; however, sometimes an acid pickle may be necessary to address these contaminates. In addition to cleaning the surface, acid treatments can aid further 鈥渁ctivating鈥� the surface which ensures the substrate is in an optimal state to undergo the conversion coating reaction.

Last, but certainly not least, rinses are critical to overall success in the application. Often overlooked, rinsing ensures the parts are free of residual chemistry and contaminates, and ready for the next stage in the application. Utilizing flowing and counterflowing rinses are a best practice in ensuring these tanks stay free of contaminates and in minimizing the net water use for the line. Maintaining these tanks, along with implementing effective cleaning and acid steps will ensure that your phosphating process continues to produce the right coatings for you.
