Pickling and Passivation -- Sterilize Your Tools

When you're working in the medical field, cleanliness is not just next to godliness; it's everything. Back before sterilization became a normal part of practicing medicine, more people died of infection from treatment than from their original injuries or diseases. These days, sterilization is pretty commonplace, and almost reflexive. Passivation is a part of the process that helps with medical device cleaning. This is a process that forms a protective coating over metal in order to strengthen it and to improve its appearance and give it a smoother surface, giving bacteria less places to hide. It can prevent infection and promote sterility. 

The most common pickling and passivation technique is to use metal oxides to form a protective layer over the metal instrument in order to protect it from corrosion, to strengthen it against damage, and to make it easier to sterilize. This is an important step in medical device cleaning, to make sure that the instruments being used are effectively disinfected every time you clean them, so that they next patient that they're used on is not exposed to the germs and other contaminants that the previous patient was dealing with. Sterility is very important in the control and prevention of disease.

Passivation is not only important for the health of the patients, but also for the health of the physicians and medical personnel such as nurses and medical assistants. These are the people who are handling these tools all day, who have to perform the actual medical device cleaning. These are the people who are exposed to the most contaminants because they're dealing with multiple patients throughout the day. If you want to protect your own health, then you should be thankful that these procedures exist. They exist to protect you from infection, as well as to protect the patients that these tools are being used on.

Most laymen don't know much about passivation, but that doesn't mean that they don't benefit from it. It's good that such a technique exists to prevent the spread of disease, and not everyone has to know what it is in order for it to be effective. But if you have to do any medical device cleaning, you should be thankful for it, and for the protection it affords to you. And it also makes it a lot easier for you to keep your tools and devices clean and germ-free to prevent the spread of disease.To Know more about pickling and passivation please visit: http://www.astropak.com/pickling-and-passivation.php

Passivation – Proper Equipment Cleaning is Vital to the Medical Community

When it comes to medicine one of the most important things that needs to be cared for that is left in the background of the medical profession is making sure that equipment is clean. Passivation is often used for deep cleaning of the metal on medical equipment leaving no chance of an unclean surface being left behind. It is vital that the equipment be germ free and ready for use in the medical facility and this is one way to ensure that this is done. Patients rely on the medical equipment being safe for their use.

Using Passivation for cleaning of medical equipment is an impressive step that the medical community has taken to get the best results possible. Disinfecting the equipment is the only way to ensure that the patients are not being left at risk for infection or disease or the transfer of illness. Without these securities it would be impossible to ensure that each patient was safe from harm and able to undergo procedures that could save their lives. Sending out equipment for this process is costly but is certainly worth the payback.

Regardless of how the medical device cleaning is accomplished it is the facilities job to ensure the each patient is protected from risk and this is something many patients likely take for granted. Hospitals are an excellent example of a location where patients could easily be at risk for thousands of illnesses, disease and infection daily. Hundreds of people move through a hospital every day and not maintaining clean equipment would cause major havoc on the systems set up to help the patients. Not only do patients come in contact with the equipment but hundreds of employees, visitors and other passersby that go through the facility.

While doctor's offices and clinics have a much smaller volume of individuals at risk through the doors in a day it is still essential that the medical device cleaning procedures be set and adhered to on a daily basis. Clinics, in particular, are often faced with an overwhelming number of individuals with health issues that could be easily spread from patient to patient without proper cleaning of the equipment. Making sure that the time is taken to care for the equipment on a regular basis is all that stands between the patients and outbreaks of substantial potential. Taking the time to decide on a procedure and sticking with it is the only way of making it standard and a part of the routine ensuring it is consistently accomplished.For more information please visit our website:http://www.astropak.com/medical-device.php

Passivation – Getting Maximum Performance from Stainless Steel

Although the beauty of stainless steel is that you don't generally need to put any type of coating on it, when you are using this material in any sort of industrial process, it may be prone to free iron contamination. With a process known as passivation, you can remove these iron compounds with the use of a chemical dissolution, such as a treatment with acid solution. This helps enhance the performance level of stainless steel or other materials, preventing premature corrosion or deterioration and increasing the material's lifespan.

Passivation is a combination of a cleaning process, because it removes the iron compounds, and is also a protective coating at the same time because it prevents the buildup of any further iron compounds or oxidation. This process begins with a thorough cleaning of the material that is being treated, which is capable of removing coolants, grease, oil, or any other residues that are left behind on the surface of the steel. When steel is used in fabricating machines, they can leave behind their mark in minute amounts. Any type of cleaning can be used to start this process, whether it is soaking the steel in an alkaline solution, or cleaning it with solvents that are specifically designed for this purpose.

After these various residues are removed, the next step to passivate the steel is to place it into a passivating solution. These are usually based on nitric acid, although there are alternative options including citric acid for a more environmentally friendly solution. These will vary in terms of temperature, the concentration of the nitric acid or other passivating agent, and the time that the steel must spend in this immersion. In general the period will range for anywhere from 20 minutes to an hour, depending on the concentration. There are many different variables to include in this length of time. 

Another factor to consider when passivating stainless steel is the type of steel that you are using. Be sure to consult with an expert in this field if you have no experience with preparing industrial materials or using acid baths, because if you use the wrong solution or leave the steel in for too long of a time period, there could be negative results. This could include the entire piece of steel dissolving if you are not careful. For this reason, it's always important to get professional guidance or send off your mechanical parts for passivation by professional services.To know more about passivating stainless steel please visit:http://www.astropak.com/ultra-pass-passivation.php

passivation - Protecting Stainless Steel


Unless you work with stainless steel or have a number of stainless steel items in your home, you likely know little about protecting the material. Some people believe there is no way to really protect stainless steel and that protection is often unnecessary. Stainless steel is a strong material, which is why it is such a popular material for making appliances and durable goods. Luckily, there are ways to protect your stainless steel against damage. Passivation is a chemical process that creates a barrier on stainless steel, protecting it from damage. The process protects against corrosion and is an excellent way to maintain the value of stainless steel materials.

Some metals naturally form passivation layers without any assistance from man. Over time, a layer forms and provides protection from damaging elements. It is possible to recreate this layer when a person wants to keep their stainless steel items in like-new quality. The natural formation is usually stronger than the man-made version, but man-made versions of protection do offer some barrier to corrosion. Acid is often used in the passivation of stainless steel tanks. It is used when the tanks are cleaned, creating layers of protection inside of the tanks.

If you want to passivate stainless steel, you want to create a surface of protection. The film on the surface of the steel causes the surface to lose its chemical reactivity. This is why it is such a popular option for tanks that hold chemicals. It lowers the corrosion rate which means the tanks are going to last longer. Companies can use non-passivated tanks, but in the long run it ends up costing them a lot more than if they had their tanks treated.

Passivation occurs when free iron, oxide scale, metal chips, iron particles and various other deposits affect a metal. This corrupts the stability of the surface. When you put dangerous chemicals into a container and these chemicals cause a reaction and mix with the steel, it can create dangerous breathing conditions and even explosions. Even if the chemical is not originally dangerous, mixing the chemical in an uncontrolled stainless steel container can make it dangers. The chemical interaction leads to a separate substance that is often much different than the original. This is why passivating stainless steel is such an important part of working with the metal. In order to protect steel from corrosion and maintain a safe storage environment, you need to do everything possible to create a protective passivated layer.

Passivation - What You Should Know

Once stainless steel is cleaned, it needs to go through the passivation process. This is a chemical process that helps to eliminate oxidation and ensure that the stainless steel is in its best shape possible to be used for food and other manufacturing and transportation needs. This process is done to make the surface resistant to corrosion, or more passive, so that it can be used effectively and safely. Passivation is performed using materials like citric acid to ensure that the iron and iron compounds are removed from the surface, but the treatment ensures that the stainless steel itself isn't affected.

In some cases, passivation of stainless steel will include the process of electropolishing. This process allows for a much more effective result because it uses electrochemical technology to produce the best results. Between the chemical cleansing and the polishing stages, stainless steel can be kept cleaner and made ready for use in a variety of different situations. During the handling and processing of stainless steel, things can cause abrasive particles to become embedded in the stainless steel, which is where the process of polishing becomes so helpful to ensuring that the material is prepared accordingly for any type of situation that it may face.

In some cases, stainless steel is used to transport liquids and other materials that leave a greasy residue on it. This is when the vapor degreaser comes into play. This process includes using solvents in vapor form to remove the grease from the surface of the stainless steel, further cleaning it and making it more ready for the next task at hand. All together, these steps are designed to ensure that stainless steel is all ready to use for whatever it is going to be used for, no matter what type of situation that might be.

With passivation of stainless steel, a lot of things can happen. Companies that deal with any type of stainless steel materials for foods and liquid consumables need to make sure that these processes are always followed carefully for the best results. Of course, there is also a need for this process in some other applications. No matter what the process is used for, it is an effective one and a necessary step for proper use of stainless steel holding and processing containers of all types. There are a variety of ways to approach this situation, depending on a company's specific needs, but the basic process is always the same. For more details visit:
