Corrosion Prevention Guide
Corrosion is defined as the alteration of a material by chemical reaction with an oxidant. It is characterized by the destruction, the weakening of the progressive deterioration of the material.
Corrosion occurs when a material deteriorates due to environmental factors. Corrosion is a natural process that occurs when three conditions are met :
Effects on the metal
Corrosion affects metals in many ways. By availing Corrosion protection spray when metal structures corrode, their integrity is weakened and they are more likely to collapse. Once corrosion begins, it can spread quickly, making it necessary to be vigilant and prevent it from the start.
Corrosion prevention methods
Here are the commonly used methods for preventing corrosion.
Choice of metal used
A simple measure of prevention against corrosion is the use of corrosion-resistant metal Marine protection spray is easily available. Aluminum and stainless steel are typical examples of these metals.
An economical method of preventing corrosion is to apply a coat of paint. The paint acts as a barrier between the metal and the elements that prevent the flow of the electrochemical charge that causes corrosion.
The powder coatings are economical solutions for prevention against corrosion. A dry powder is used to cover the surface of the metal. Then, the metal is heated, which allows the powder to fuse with the metal in a uniform coating. The various powder like Rust prevention spray compositions used are polyester, nylon, urethane, epoxy, and acrylic.
Master the environmental conditions
Corrosion is the result of a chemical reaction between the metal and certain gases in the environment. If the presence of these gases can be controlled in the environment, then Biodegradable Corrosion protection the occurrence of the reaction can be controlled. Simple measures in this regard include reducing exposure to rain or atmospheric moisture. Complex measures would consist of controlling the sulfur/oxygen/ chlorine content of the environment.
An example of a complex measure is the treatment of water in boilers using water softeners. Softeners remove calcium and magnesium from water, which are highly reactive metals that increase the risk of corrosion. In addition, softeners also help manage the oxygen content and alkalinity of the water.
Sacrificial coatings
Corrosion prevention can be achieved by coating Dielectric corrosion protection the surface of the metal with another metal that has a comparatively higher or lower oxidation potential. The sacrificial coatings are of two types: anodic protection and catholic protection.
Anodic protection
In the anodic protection, the surface to be protected is covered with a less reactive metal (for example in). In the example given, the tin is much less sensitive to corrosion, so that the surface on which it is applied will be safe as long as the coating is there. The reason why this anodic protection is called is that in this process, the metal surface to be protected becomes an anode.
Anodic protection is used to protect carbon steel storage tanks that are used for the storage of 50% caustic soda and sulfuric acid.
Catholic protection
The application of a zinc layer to an iron-alloyed steel surface is a common example of cathodic protection. This process is also called galvanizing. Since zinc is more reactive than steel, it corrodes. It will oxidize, which will prevent corrosion of the steel. The reason for this cathodic protection is that in this process the metal surface to be protected becomes a cathode.
Power and electricity have revolutionized human living standards exponentially in the recent past. The contribution of power cannot be compared to any other when it comes down to making a simple comparison. Power has revolutionized our industries, agriculture, space technology, communication, automobile industry, and the list can just go on and on in this regard. Scientists, engineers, and inventors have also worked immensely in the field of power to make it more accessible and especially in recent times, portable.
Batteries are basically nothing but portable packs of power. They function on the chemical reaction between the cells and the electrolyte solution to react an electric current which in turn provides power to our portable battery-operated devices through the electric circuit built in the battery to transmit stored power in form of electric current. In simplest terms, batteries are composed of chemicals which react to give electric current.
There are different compositions used for creating batteries such as Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-Mh), Lead Acid, Lithium-Ion (Li-ion), Lithium Polymer (Li-Po). These acronyms have become synonyms with the names for batteries commonly used in our homes, offices, transport and communication devices.
Batteries are everywhere around us today. They are in our smartphones, laptops, clocks, cars, security cameras and so on so forth. It is very easy to sometimes forget that they are in operation around us. But, rest assured they are providing the power to the devices, gadgets and equipment’s which dictate our lives today.
In the information below we shall provide information towards the basic security precautions related to LiPo batteries:
Authentic Charger:
There are many third-party chargers available in the market which claim ability recharge any type of batteries. But this should be avoided. You should use a compatible charger to recharge your LiPo batteries especially in the case of RC LiPo batteries.
Errors in Human Handling:
The most safety-related errors occur due to lack of knowledge and poor human handling. Batteries need to be handled with care with precautions. They need to store in an appropriate climate and temperature as prescribed by the manufacturer. They should be dropped, deformed, scratched. During traveling, make sure they are not stored in one place for too long. Be aware regarding charging them properly, not overcharging and not undercharging.
Storage
Storing is often a big question mark when it comes to understanding LiPo batteries especially 2s, 3s, and 4s LiPo battery. If you are someone who owns a lot of battery-related gadgets, buy an appropriate storage box for the batteries. While buying the storage box give preference to features like fireproof. It is also wise to keep a fire extinguisher handy in case of any fire incidents.
Most importantly store the batteries properly. Choose a special location on your premises where there is not too much heat and not too much cold including any temperature fluctuations. Remember! Batteries are constantly churning a chemical reaction. Safety of the battery is eventually your safety.
Discarding old batteries
Discarding or disposing of old batteries is another important safety issue. Recycling them or dropping them at government-sanctioned hazardous waste centers is the best option. It is very unsafe to just let them go in your regular garbage.
