Benefits of Electrostatic Enamel Powder Coating Line
 

Environmentally-friendly.
Electrostatic enamel powder will not produce pollutants and harmful gases during the production process, and meet the national production requirements, and promote the development of the electrostatic enamel powder coating line in the direction of functional innovation, healthy and environmentally-friendly, and ecological applications.

Reduce enamel surface defects.
Electrostatic enamel powder is coated by electrostatic spraying. Its working principle is that the electrostatic spray gun adopts the principle of high voltage generation. Under the voltage of 70~100kV, the gun head forms a negatively charged electrostatic field. The workpiece to be sprayed is grounded and the workpiece is in the spray room. When passing through the spray gun, the spray gun begins to spray powder, and the positively charged workpiece and the negatively charged powder are attracted to form a powder coating, which improves the gloss of the enamel surface and reduces the defects of the enamel surface at the edge.

Reduce the coating process.
Electrostatic enamel powder can be used directly without grinding into enamel slurry, and the drying process after spraying is omitted.

Reduce production costs.
After deep processing of enamel frit into electrostatic enamel powder, the utilization rate of enamel material can be as high as 97%~98%. In today's increasing production cost, increasing the utilization rate of raw materials will reduce production costs and bring huge value to enterprise production. At the same time, it can use "two coat and one firing" process, no special decarburized steel plate is needed. Everyone knows that most of the cost of enamel products is spent on steel plates. Compared with ordinary steel plates, the price of an enamel-specific decarburized steel plate is more expensive. The production of steel plates will directly reduce production costs.

Electrostatic Enamel Powder Coating Line: Powder Coating Coverage Formula

 

 

Now that you have all the data you need, you can apply the powder coating coverage formula.
Assumption: The Powder Coating Industry standard is 192.3 square feet of coverage per pound of powder. This pound of powder would be at 1.0 specific gravity and applied at a thickness of 1 mil with 100% transfer efficiency. In other words, this is how much surface a common powder could cover if no powder was wasted and you only needed a thickness of 1/1000th of an inch.
So the formula would be:
Actual Coverage Rate (ACR) = 192.3/Specific Gravity/Mils x Transfer Efficiency (as a decimal)
Example: Powder A has a 1.5 specific gravity and is being sprayed at 2 mils with 50% transfer efficiency. The powder cost is $5.00 per pound. The part being sprayed has 3 square feet of surface area.
ACR = 192.3/1.5 (specific gravity)/2 (mil thickness) x .50 (transfer efficiency)
ACR = 32.05 square feet per pound of Powder A
Next, take your cost per pound and divide it by your ACR.
Cost per square foot = $5.00 (cost of one pound of powder)/32.05(ACR) = cost is $0.16 per square foot of coverage by Powder A
Multiply this cost by the square footage of your part's surface area and you'll know the cost of the applied powder.
Cost Per Part = 3 (square feet of part) x $0.16 (cost per square foot) = $0.48 per part in powder cost.

 

Electrostatic Enamel Powder Coating Line: What Is the Best Thickness for Powder Coating?

 

The normal standard used in powder thickness measurement is the mil, where 1 mil is equal to a thousandth of an inch (1/1000"). So if the manufacturer's specified thickness is 2 to 5 mils, the final cured thickness of the powder should be between 0.002 and 0.005 of an inch. The metric unit of measurement is called the micron where 25.4 microns is equal to 1 mil. Applicators must apply the powder evenly and according to the product specification sheet.

The standard film thickness for a standard powder coating for optimum mechanicals is between 60 and 80 microns (~2-3 mils).

Thickness measurements of powder can be taken before and after curing. Substrate type, thickness range, part shape, and economics determine the best method to be employed.

For uncured applied powders, height measurement can be performed with powder combs and with magnetic gages employing special powder probes. These techniques are destructive and may require recoating the part. Coating powders generally diminish in thickness during the curing process so these procedures require a reduction factor be determined to predict cured film thickness.

Ultrasonic instruments also measure uncured powder, but do so without touching the surface. Instead of measuring powder height, they automatically display a predicted cured thickness result. For after-cure measurement, a variety of hand held instruments are available. These non-destructive instruments employ either magnetic, eddy current or ultrasonic principles depending on the substrate. Less common methods include micrometer measurement, destructive dry film methods such as cross-sectioning and gravimetric (mass) measurement.

Powder coating continues to be the fastest growing of all the finishing technologies. It is an attractive paint-like protective finish that is long lasting, and highly resistant to chips, scratches, and fading. It provides a seamless coating from a virtually unlimited selection of colors, textures and finishes.

Powder coating is a cost effective, one step process that doesn't require successive coats and long curing times. Powder particles used are a mixture of finely ground pigment and resin particles. Charged powder particles are transferred onto an electrically grounded surface. A variety of processes exist for powder application. These applications range from electrostatic spraying for thinner coatings (0.001" – 0.010") to dipping in a fluidized bed for thicker coatings (0.007" - 0.040").

 

Electrostatic Enamel Powder Coating Line: What Is the Difference Between Powder Coating and Enamel?

 

 

Powder coating done properly is tougher than stove enamelling and air drying paints. This means it will take more of punishment before chipping.
There are no solvents used during the application and so it is environmentally greener.
Requires factory processing making a better chance of the component being stripped and blasted, for better corrosion resistance and adhesion.
It produces a more waterproof barrier than liquid paint (for comparable thickness) and therefore offers better protection against corrosion.
To hide metal imperfections, a Powder coating finish can achieve in two coats, what stove enamelling requires in 15 or more coats.
Therefore the price is comparable, or even cheaper than stove enamelling.
Powder coating is more resistant to scratching and marking.
Good quality powder coatings are available in high gloss and have negligible orange peel.
Dirt is easily washed off.
Powder coating can be compounded, polished and waxed like any other paint.
