A fine mist sprayer is a device that atomizes liquid into micron-sized fine particles. It is widely used in many industries such as cosmetics, medicine, agriculture, cleaning and disinfection. The design and function of the sprayer determine the type and performance of its applicable liquid. The physical and chemical properties of different liquids have a direct impact on the spray effect, equipment durability and safety of use.
Applicability of water-based liquids
Water-based liquids are the most common spray objects of fine mist sprayers, including pure water, floral water, toner, liquid medicine, etc. Water-based liquids have low viscosity and strong fluidity, and are easy to achieve efficient atomization in the nozzle. The sprayed droplets are uniform and small in size, covering a large area and can evaporate quickly, which is suitable for facial care and medical spraying. The material requirements of the sprayer for water-based liquids are mainly anti-rust and anti-microbial contamination. Water-based liquids are less corrosive to nozzle materials and have a longer equipment life. Sprayers suitable for spraying water-based liquids are mostly made of plastic or stainless steel to ensure safety and hygiene.
Spraying characteristics of oil-based and mixed liquids
Oil-based liquids such as essential oils, aromatherapy oils, and skin care oils have higher viscosity than water-based liquids, poorer fluidity, and greater difficulty in atomization. Fine mist sprayers require specially designed nozzles and delivery systems to overcome the adhesion and flow resistance of the oil and prevent nozzle clogging and dripping. In terms of materials, nozzles and pipelines must use oil-resistant corrosion materials, such as Teflon coatings or polymer composites. The droplet size formed after the oil-based liquid is sprayed is usually large, which is suitable for local moisturizing, aromatherapy diffusion, and other needs. For mixed liquids, such as water-oil emulsions, the stability of the two-phase liquid and the uniformity of the spray need to be considered, and the sprayer is required to take into account the atomization effect of different components.
Spraying adaptability of highly volatile liquids
Highly volatile liquids such as alcohol, acetone, and disinfectants are widely used in disinfection, cleaning, and medical scenarios. When spraying such liquids with fine mist sprayers, it is necessary to ensure that the equipment has good sealing and chemical corrosion resistance. Highly volatile liquids evaporate quickly, and the spray particle size is fine and uniform. They can quickly cover the surface and reduce liquid residue, thereby improving disinfection efficiency. Sprayers are usually made of corrosion-resistant plastic or stainless steel to prevent solvents from damaging the equipment. At the same time, the spray design needs to avoid uneven spraying caused by excessive evaporation of the liquid. The safety of highly volatile liquids also needs to be considered to avoid flammable and explosive risks in the spray area.
Restrictions on the spraying of viscous and high-concentration liquids
High-viscosity liquids such as honey, syrup, and concentrated essences are difficult to spray through traditional fine mist sprayers due to their poor fluidity. High-viscosity liquids require higher pressure and specially designed conveying mechanisms, otherwise they are prone to nozzle blockage and inadequate atomization, resulting in large drops of liquid dripping, which is a serious waste. Some high-end sprayers are equipped with heating functions or ultrasonic atomization technology to help reduce liquid viscosity and improve spraying effects. In general, the application of viscous liquid spray is limited, and appropriate spray equipment needs to be selected according to the specific characteristics of the liquid.
Spray applicability of liquids containing solid particles
Some liquids contain suspended particles, such as medicinal suspensions, agricultural pesticides, and certain beauty serums. Fine mist sprayers need to have sufficient channel diameter and anti-clogging design to ensure that particles pass through the nozzle smoothly. Ultrasonic atomizers are suitable for spraying liquids containing particles because of their lack of mechanical wear and wide channel design. The limits on particle size and concentration must be strictly controlled to avoid equipment damage and uneven spraying. Material corrosion resistance and wear resistance are also key to ensure long-term stable spraying.
