What is static electricity?
We all have experienced the effects of static electricity, static electricity is electricity does not flow or electrical charge-the charge is at rest. We certainly know when a ruler or plastic ruler rubbed on dry hair, then brought closer to small pieces of paper, then small pieces of paper will be attracted to and stick to the ruler. Why does it happen? Because plastic ruler that is rubbed on the hair, into an electric charge. The electrical charge that causes small pieces of paper can be attracted to the ruler. Living in the country four seasons makes us often exposed to electrostatic discharge during the winter when we comb the hair, out of the car, dressing, ironing, etc.
How could that happen ?
In general, during the winter, the air becomes dry, which means also filled with negatively charged electrical particles. Particles of electricity will continue to stick to our body in the long term and can accumulate until finally these particles are separated from the body when we touch something conductive (metal, water, and others), so that the electron excess of our body undrained to there and made us feel stung, the sound of crackling, sometimes visible spark api.Dalam normal conditions these effects, at most, only shocking but not dangerous. However, in industrial environments, the electrostatic effect may cause a spark that could detonate flammable gases, causing a dust explosion, or interfere with sensitive electronic equipment. The concrete floor is usually conductive enough for moisture from the pores of the concrete is enough to drown out the electrostatic charge on the surface. However, epoxy floor paint is often used to make the surface harder, cleaner or chemical resistance is an insulator that can cause major problems in some circumstances.
Where Epoxy Floor Paint Anti-Static Used? Every industry where dust can cause a problem or static manalistrik can result in unwanted effects is required to use Epoxy Floor Paint Anti-Static. Common examples are: the munitions industry, electronic industry, industrial tube TVs, industrial magnetic tape, industrisemi-conductor, industry micromechanics, industrial gyroscope, industry CD and DVD players, industrial optics, industrial photographic film, laser industry, biotechnology, industrial antibiotics, genetic engineering, pharmaceutical industry, operating rooms and medical devices, heart valve industry, the food & beverage industry, immunodeficiency therapy and industries that use combustible materials. How to Choose Paint Epoxy Floor Anti-Static? Needs of each industry to the floor Anti-Static course vary, the exact placement will maximize functionality and reduce the cost required. The following questions can help you to choose Epoxy Floor Anti-Static: · How many prisoners range do you need? (Conductive Range: 104 – 106ohm or Dissipative Range: 106-109 ohm). · How much of the weight that will be traversed the floor? (Light Duty, Medium Duty or Heavy Duty) · How often traffic that will pass the floor? (Normal or Very Dense) · Chemicals what will be on the floor surface? · What color will be used? (Epoxy Floor Anti-Static has limited colors). How Applications Epoxy Floor Anti-Static? The following are the technical requirements and application stages Epoxy Floor Anti-Static:
STANDARD TECHNICAL REQUIREMENTS:
Concrete strength of at least K-250, trowl finish (no acian)
Concrete has dried, have a minimum of 28 days old.
Maximum humidity has reached 5%
Concrete surface smooth, flat and not
Has a grounding point in each column ≤ 5 ohms (standard PUIL 2000)
Surface preparation is a very important factor to the adhesion of the paint to the concrete, the concrete surface must be clean from dirt, dust, grease and oil. Concrete surface should be cleaned of laitance (a layer of slippery concrete surface). Digurinda concrete surfaces using diamond concerete planner, dust cleaned with a vacuum cleaner, after a clean, mop the concrete surface with a solvent cleaner to clean oil and grease.
Concrete Epoxy Primer (MAXIFLOOR® MFP-250 HB)
Functioning as an adhesive penetration into the concrete so that the paint with a very strong glue. 1 x layer is applied at a dose of 150 g / m2 using a mohair roller.
Epoxy Body Coat (MAXIFLOOR® MFT-353 SL + Silica Sand)
Serves to form a solid layer, leveling the surface and increase the thickness of that power Anti-Static each part is relatively the same. MFT-353 SL mixture is stirred with a mixer at a dose of 1000 grams + 800 grams of 50/60 mesh silica sand, every square meter.
Serves to connect each part Epoxy Primer Anti-Static to every point grounding. Created shaped box the size of 5m x 5m like a chessboard, using 3M brand copper tapes with a width of 12 mm.
Epoxy Primer Anti-Static (MAXIFLOOR® MFP-390 WB)
Serves as a mediator who holds the static from the floor surface and will connect to the grounding (earthing) via copper tapes. 1 x layer is applied at a dose of 200 g / m2 using a mohair roller.
Anti-Static Epoxy Self-Levelling (MAXIFLOOR® MFT-395 SL)
Serves as the final layer is a hard, wear resistant and resistant to p certain chemical substances. Was applied at a dose of 1000 g / m² mixture, stirring with a mixer, poured and drawn with sweeze, leveled with a spike roller.
