The Trending Paint Application Methods That Are Frequently Used

February 15th, 2018 Posted by blog No Comment yet

In lieu of the regulations issued by the government for reducing air pollution, industries are now using coatings that contain less organic solvent (volatile organic compounds or VOCs). These days, industrial paint equipment uses advanced application methods that improve transfer efficiency, reduce wastage and decrease efforts.

With transfer efficiency, it means the amount or percentage of coating material that actually coats the product versus that wasted in the form of overspray. High transfer efficiency not only helps meet environmental regulations and cuts costs but also it makes your workplace safe to work. Below are enlisted the basic methods used for applying paint in production installations.

Industrial Paint Equipment

Spray Methods

Industrial paint sprayers can be classified into three categories, namely air, hydraulic or centrifugal. These general types have been further divided into conventional air-atomized, airless, air-assisted airless, air electrostatic, airless electrostatic, air-assisted airless electrostatic, high-volume low-pressure (HVLP), and rotating electrostatic disks and bells.

  • Air Atomized Spraying – In the air atomized spraying technology, the paint under pressure is pumped into conventional spray guns so that it gets mixed with the stream of compressed air. The greatest asset of conventional air-atomized spray equipment is its versatility.
  • Airless Spraying – In the airless spraying process, paint under pressure is made to pass through a small orifice in the gun, atomizing it in the same manner as a nozzle attached to a garden hose. It always lowers the viscosity.
  • Electrostatic Spraying – Under the electrostatic spraying equipment, as the droplets pass through an electrode they become charged. But it has two disadvantages: First, the higher film builds on outside corners, edges and around cutouts. Second is the lower film build on inside corners and recesses.
  • Airless Electrostatic Spraying – Under the airless electrostatic spraying, high-pressure hydraulic spray guns are used. They also charge the atomized droplets. Air-atomized electrostatic spraying improves transfer efficiency.

Non-Spray Methods

Under the non-spray methods, there are different methods such as dip coating, flow coating, centrifugal coating, roller coating and electrocoating.

  • Dip Coating – In the dip coating products to be painted are immersed in a tank full of coating material. The excess of the paint is drained off in a solvent-saturated atmosphere and then it is dried or cured.
  • Flow Coating – Flow coating overcomes some of the limitations of dip coating. The paint is pumped from a reservoir over the upper surfaces of the products through hoses and nozzles. The paint flows over and down thus covering the sides of the products.
  • Centrifugal Coating – In centrifugal coating, firstly, the small parts are loaded into an inner basket. Thereafter, the tank is filled with sufficient coating material to cover the basket of parts, and then it is emptied. Also known as “dip-spin” coating it is used for finishing of small parts in large volumes.
  • Roller Coating – For finishing flat sheets and coiled metals, roller coating is the extensively used method. When the substrate and rollers travel in the same direction and at the same speed, the method is called direct roller coating.

To achieve the higher efficiencies and more production, new and trending industrial paint sprayers are being used. These are more efficient methods as compared to the conventional methods and equipment. The Kremlin industrial paint equipment reduces the material costs and makes the coating process easier.

Tips To Keep In Mind While Choosing Industrial Paint Sprayer

Industrial paint equipment can make a tremendous difference in your production and finish quality. To maximize your benefit from your industrial paint gun, it is advisable that you choose proper industrial paint sprayer which is very much suitable for your application needs. Always keep in mind the below-mentioned tips while choosing the industrial paint gun that meets all your finishing needs perfectly.

Tips To Keep In Mind While Choosing Industrial Paint Sprayer

WHAT EQUIPMENT WILL YOU PRIMARILY PAINT? The first and the main thing that will help you out in selecting the proper type of spray gun is Coating, whether it be HVLP or Conventional, Gravity, Suction, or Pressure-fed, and the proper fluid nozzle size to use. It is ultimately best to test the material with your spray gun to determine if it will work for you, you can also choose well by evaluating the following.

If the material is very heavy bodied, you will likely use a conventional spray gun. This will allow application of a lot of air pressure to atomize the material. Also, the conventional spray guns are cheaper than the HVLP Spray Guns which make them a good choice if you consider the cost of maintenance in future. If the material is of light viscosity, you can use HVLP Spray Guns. It has an advantage: it wastes less paint than conventional spray guns. For lighter bodied material, you can use suction or gravity fed spray guns in HVLP or Conventional application styles.

HOW MUCH ARE PRODUCTION YOU LOOKING TO ACHIEVE? This question will help you look for the answer as to which air cap and fluid nozzle setup would be proper to use the spray gun? Essentially, the larger the fluid nozzle the quicker the spray gun will apply coatings and the better it will be to apply heavy coatings. But if the spraying needs to be done over the heavy materials, then consider a large fluid nozzle.

For lighter coatings, a small fluid nozzle is best suitable. In addition to the fluid nozzle, the air cap needs to be properly matched to your spray gun. The more CFM an air cap handles, the larger the production ability of the air cap. If you have a large nozzle, you will need a large air cap and if you have a small nozzle you typically will want a smaller air cap.

YOU NEED THE SPRAY REGULARLY OR FOR SINGLE PROJECT? This question will help you decide whether a high-quality spray gun or a budget spray gun will be best suitable for your needs. Many times people end up buying the low-priced spray gun and continue replacing it year after year. But they do not tend to realize that this process is expensive in the long run. On the other hand, the high-quality industrial paint sprayer can be kept for a lifetime and require only occasional replacement of a part. Also, the higher quality industrial paint guns maintain a uniform spray pattern over multiple uses.

Keep the aforementioned three points always in mind as they will help you determine the proper industrial paint equipment for your facility.

The Advantages of Using Industrial AIRMIX® Spray Systems

August 9th, 2017 Posted by blog No Comment yet

Finalizing what kind of spraying system one should use for industrial finishing application often becomes a complicated task.

You essentially have four choices when it comes to conventional non-electrostatic spray painting: air atomizing, high volume, low pressure (HVLP), air-assisted airless and AIRMIX® spray. This blog details the advantages of AIRMIX® industrial paint equipment.

The Advantages of Using Industrial AIRMIX® Spray Systems

The AIRMIX® spray systems offer acceptable transfer efficiency, minimal material waste if set up correctly, decent finish quality, good one-pass coverage, and cost effectiveness. Other advantages have been listed below in detail:

LESS MATERIAL WASTE – The biggest advantage of using AIRMIX® spray systems over conventional air spray is the waste. Conventional air spray uses high-pressure air jets to send particles of atomized paint toward a surface. This leads to the creation of a “cloud” that disperses many of these particles into the air, creating overspray, which is highly wasteful. On the other hand, AIRMIX® spray systems hydraulically atomize the paint without the introduction of atomizing air, which not only minimizes overspray but also reduced solvent usage.

UNIFORM APPEARANCE – With industrial spray painting equipment, you can achieve a higher quality paint finish with a single application. This is because of the reduced compression associated with it. This also reduces the need for repeated touch-ups and resprays on the end product.

SUPERIOR CONTROL & EFFICIENCY – Instead of using pressurized air to atomize and deliver paint, AIRMIX® spray systems use hydraulic pressure through a specially designed spray tip to create the fan pattern. These tips come in a variety of sizes to accommodate many different applications. Also, instead of using solvent, inline fluid heaters can be used to lower paint viscosity. Using solvent to reduce paint viscosity directly affects coverage capability because the solid content of the material gets dissolved.

SUPERIOR FINISH AT A LOWER COST – When choosing the industrial paint equipment another thing that people take into consideration is the quality of the finish. AIRMIX® spray systems are capable of providing satisfactory finish quality in the right application. Overall, there is less material waste, and no need for compressed air atomization when an airless spray system is in operation.

VERSATILE APPLICATIONS – Industrial spray painting works with a wide range of liquid materials such as paints, stains and primers, and offers a high degree of control and uniform coverage on surfaces such as wood, metal, plastics and fiberglass.

HIGH TRANSFER APPLICATION – Industrial spray painting systems produce a superior finish at reduced costs, with maximum utilization of liquid painting materials.

The above-listed benefits largely outweigh any other commercial painting method, the reason being the mass production of commercial heavy duty products such as planes, trains, and automobiles. The industrial painting requires fast-paced industrial paint equipment that efficiently delivers exceptional results. Depending upon the needs, there are many advantages of using conventional air atomizing methods. But AIRMIX® spray systems have significant advantages in many applications.
