How corrosion can affect the surface coating quality?

Corrosion is the deterioration of a material, usually a metal, caused by a chemical reaction to its environment. When iron or steel corrodes, the resulting product is iron oxide, which is commonly known as rust. Rust not only weakens the structure of the metal but can also cause the coated substrate to fail. There are many different types of coatings that can be used to protect against corrosion, but each has its own set of advantages and disadvantages. To make sure that the surface coating of your product will be corrosion resistant, you can make use of the Presto salt spray chamber. This is one of the amazing lab testing equipment that is useful in assessing the rust-proof ability of components to withstand corrosion due to atmospheric conditions. Here in this blog, we are going to provide you with information about how corrosion will affect the surface coating quality. We will also provide you with information about how the salt spray test chamber is helpful in testing the rust-proof ability of surface coatings. So, let us get started!

Effect of corrosion on surface coatings

Corrosion is the deterioration of a material, usually a metal, as a result of a chemical reaction to its environment. The process can produce both visible and invisible damage to the surface of the metal, and it can weaken the metal's structure. Corrosion is a major problem for many industries, as it can cause costly repairs and replacements. 

In some cases, corrosion can even be dangerous, as it can lead to structural failure. There are many different types of corrosion, but one of the most common is called rust. Rust can cause significant damage to metal surfaces, and it is often very difficult to remove once it has formed. Rust prevention is an important part of many metal-working processes. Testing the metal's surface coating or related elements beforehand can save you more amounts. Thus, with the help of the Presto salt spray chamber, you can easily assess the ability of rust-proofed components to withstand corrosion due to atmospheric conditions. It comes with a triple wall structure with glass wool insulation to make sure that you can easily perform the test using this lab testing equipment. You can easily test the corrosion properties of materials with a Salt spray chamber.

Over time, metal surfaces are susceptible to corrosion when exposed to salt water or other chemicals. In order to evaluate the performance of metal materials and coatings, manufacturers subject their products to salt spray tests. Presto salt spray chambers create an environment that simulates the corrosive effects of saltwater, allowing manufacturers to predict how their products will hold up over time. These chambers are easy to use and maintain, providing accurate and flexible results. By understanding the results of salt spray tests, manufacturers can make informed decisions about the materials they use in their products. Thus, you can easily remove corrosion from metal products with the help of this corrosion testing instrument. 

Features of Presto Cass cum salt spray chamber 

Corrosion-resistant paints and coatings are the keys to protecting metal surfaces from the deleterious effects of corrosion. In order to ensure that these products meet industry standards, it is essential to test their corrosion resistance in a controlled environment. This is where corrosion chambers come in. By simulating the conditions that cause corrosion, corrosion chambers allow manufacturers to assess the performance of their products and make necessary changes before they reach the market. As a result, these chambers play a vital role in ensuring the quality of corrosion-resistant paints and coatings.

Below we have listed the features of the Presto salt spray chamber.

• HMI-based Touchscreen Display for ease of operation
• Inbuilt PID temperature settings for accuracy
• Corrosion Resistant PT-100 sensor

Principles Of Laboratory Hot Air Oven

A Hot air oven is widely used in pharmaceutical laboratories and other material testing laboratories. With the rising awareness about the dry sterilisation process, the demand for laboratory hot air ovens is also rising. In this post, we will discuss the fundamentals of the machine.

Working principle

The working principle is based on fine gravity air convection in an electrically heated chamber. The machine is equipped with various components to ensure uniform heating throughout the chamber. Two jacket design, automatic control unit, PID controlled, PT 100 sensors, temperature preset, etc. allow the machine to work efficiently and return to normal temperature when the test process is over. It is designed to simplify the process of dry sterilisation and pre-treatment of different materials like rubber, plastic, etc. 

Inside the chamber, the air flows in a forced circulation manner, this allows the appropriate heat distribution inside the chamber. As the air inside the chamber becomes hot, it becomes lighter and moves in the upward direction. As it reaches the top, the fan inside the chamber pushes it back to the bottom. This creates a circular motion inside the cabinet and makes a consistent circular flow of the air. With this process, eventually, the optimum temperature is achieved. 

It is always to be taken care that articles kept for sterilisation should not be taken out immediately. Let the oven comes to a normal temperature and then the articles are taken out. 

Advantages of Using Laboratory Hot Air Oven

• Not all articles are suitable for wet sterilisation. It can be successfully used for materials like powder and oil which otherwise get spoiled during wet sterilisation.
• The articles do not need to be dismantled as the whole article is exposed to the high temperature for a good time.
• Even metal equipment is safe with dry sterilisation, which otherwise gets corroded in wet sterilisation.
• Dry sterilisation is safe for the operator. Unlike autoclaving, which uses a pressurised method for the wet process.
• Precautions to be taken
• It is not advised to keep the article directly on the floor and it is hotter in comparison to the chamber temperature. Perforated shelves are meant for keeping the articles that are to be sterilised.
• For the uniform heat distribution, there has to be space between the articles and ample distance from the walls.
• The glass apparatus should be wrapped with a clean cloth
• Do not load the chamber more than the prescribed limit.
