Atomization And The Science Behind It

Ever wonder how an atomizer works? We have heard it mostly from vapes and sprays but what makes atomization very interesting? Atomization is the process of reducing particles into atoms. These are extremely small in quantity. They can only be split into finer particles by using an atomizer, thus, atomizer disinfectants are widely adopted by the healthcare industry for this reason. However, atomizers can be of different processes, thus, producing different outcomes. For vapes, the atomizer produces the smoke that comes out like a cigarette, while for the industrial method it takes different types and differs in the transfer of energy. These commonly used atomizer types are pressure atomizers, centrifugal (wheel) atomizers, and pneumatic (two-fluid) atomizers. Over time, electrothermal (ET) atomizers were developed.

DeVilbliss And Liquid Atomization

Among these types, the high-pressure atomizer using an atomizer nozzle is commonly used in a liquid-based fine spray. Going back in the 19th century, the first atomizer nozzle, which was called the aspirator nozzle during that time, was invented by Dr. Thomas Devilbliss of Toledo, Ohio. It was based on the Venturi effect, the decrease in fluid pressure when liquid flows through a constricted section of a tube.

Liquid atomization is the method in which a liquid coating coming out on a solid surface is constrained to sufficient surface interference such that the liquid gets separated from the surface or splits into microdroplets like a fog or mist in the gas phase. This kind of method is widely important in spray drying, spray cooling, preparation for nano-size powders, film coating, and making emulsions.

The Smaller The Droplets, The Better

Atomizer's main function is to make isolated atoms in the gas phase efficiently. The important characteristics of atomizer for spray drying are uniformity and homogeneity of the spray. Higher pressure or centrifugal speed reduces the outlet temperature by producing a greater number of droplets with microdroplet size, thereby decreasing the final microcapsule particle size. The size of the droplets depends on the pressure and viscosity of the liquid, nozzle pressure, and speed. It also determines the particle size, the drying time, and how effective it is against germs for disinfectants.

The airDefender QDot Atomizer

What does this mean for the Qdot atomizer? Using high-pressure atomization, the intelligent Qdot atomizer spray gun gives better control on the size of the microdroplets it emits. The mist's microdroplet size is <8um compared to the commercial brands. This size traps the dust, bacteria, and viruses more effectively; and kills them before they even spread, with less chance of landing or staying on the coated surface and the skin.

Paired with the award-winning, patented antibacterial solution, it creates a powerful microdroplet coating that disinfects and adheres to the skin longer, giving longer-lasting protection for 10 to 24 hours. The blue-light sensor with its 3 pressure settings detects a motion when you move and targets the area and the germs on it with wider and fuller disinfecting coverage on your surroundings, so you never missed a spot.

Using the same atomization process, the Qdot sanitizer dispenser emits a powerful mist that is convenient to take wherever you go. It has motion and infrared sensors for a no-touch quick burst of disinfection that is automatically turned off when no motion is detected. Paired with an antimicrobial solution, you get sanitize for seconds but protected for hours.
