What is salt spray test used for?
Salt spray testing is a laboratory simulation of a corrosive saline environment. It is used as an accelerated means of testing the ability of surface coatings to withstand atmospheric corrosion.
What is SST in paint?
Salt Spray Test (SST) is a really widespread corrosion method, applied in order to check materials and surface coatings corrosion resistance.
What is a salt spray rating?
A salt spray test is a standardized and popular testing method conducted to evaluate corrosion resistance of materials and protective coatings. The test mimics corrosive environments in an accelerated time frame, allowing you to compare the relative corrosion resistance of various coatings.
Is spray liquid or gas?
In a typical aerosol, some of the propellant exists as a gas under pressure above the product. This gas pushes down on the liquid, forcing it up through the dip tube and out the valve when it is opened. The liquid is a mixture of product and liquified gas.
What are sprays made of?
Most everyday, household aerosols are made from a thin sheet of steel coated with another material to stop it rusting or reacting with the product or the propellant. Traditionally the coating is tin, often applied by electroplating, which turns the steel into a material called tinplate.
Why is spray drying used?
Spray drying offers a gentle method of drying by exposing substances to only a short burst of extreme temperature, then providing a cooling effect via the evaporation process, which protects spray dried pharmaceuticals from higher bulk temperatures.
Do female cats spray?
Urine spraying is more likely to occur in both male and female cats when they reach sexual maturity, around 6 months of age. While spayed and neutered cats can also spray, it's less likely if the cat is in a stress-free environment and feels that their social and emotional needs are being met.
What is a spray of flowers?
Sprays are large, flat bouquets of long-stem plant material. They are either carried or placed on caskets or at tombs as commemorative offerings. If the plant material used is short-stemmed, wire is used to add length.
What is dog spray?

What is a spray system?
A spray system effectively suppresses dust and odor in certain commercial and industrial applications. A spray stream product produces a column of air that projects a dense spray of atomized water. The water can travel distances of 150 feet or more, and are engineered for industrial applications.
What is the process of water absorbing particles?
If properly dispersed in large quantities, water droplets can absorb individual dust and odor particles and completely remove them from the air in a process known as adhesion.
Why is misting water important?
Misting systems take advantage of both the liquid and gas properties of water to achieve effective dust and odor control, reduce ambient temperature in cooling applications, and increase relative humidity levels.
How does mist cooling work?
Mist cooling systems operate through the process of converting streams of water into tiny droplets about 15 microns in diameter. This is just the right size for absorbing and getting rid of airborne dust and odors in industrial settings. The droplets also evaporate quickly, reducing the temperature by up to 40 degrees Fahrenheit, allowing you to stay cool without getting wet or feeling damp. The best results are seen when the temperature is over 80 degrees Fahrenheit with a steady air flow and humidity level lower than 50%.
Why do misting systems leave water everywhere?
This is because of poor design and inconsistent water pressure, which make water droplets bead rather than form micron-sized water droplets.
What happens to humidity when water evaporates?
When water is evaporated and the air exchange is limited, relative humidity increases. By controlling the amount of moisture and the air flow, any relative humidity level can be artificially created and precisely maintained. This is how humidification systems are designed. They utilize the same basic components of a cooling system, ...
