Unit 3: electricity in nails

Electricity

a form of energy that

produces light, heat and magnetic and

chemical changes.

Electric current

the flow of electrons

conductors

Materials that transport electricity easily

insulator

a material that doesn’t allow a current to

pass through it.

source

provides the force necessary to move the electrons in the conductor.

When too many

appliances are put on one circuit and are operated at the same time:

Overload

Overload

Occurs when more current flows than the line is designed to carry

Short Circuit

Occurs when a foreign conductor (such as liquids spilled on

electrical wiring) comes in contact with a current, interrupting its path

fuse

will heat up and the wire will melt, breaking the circuit and cutting the

flow of electricity

circuit breaker

reusable device that breaks the flow of current when an overload

occurs

GFCI

a building code requirement for

installation in any area where water and electricity could come into contact,

GFCI can sense

current leakage in an electric circuit and will

interrupt power if there is contact with water, preventing electric shock

Visible light

Portion of the

electromagnetic spectrum humans

can see

Ultraviolet light

invisible to the eye

o Creates energy that cures gel

product on the nail plate

UV light triggers

the photo initiator contained in the gel

system.

photo initiator

uses the absorbed UV light energy to link the molecules into

long chains, creating polymerization.

UV lights wavelength is

Shorter than violet

Shorter wavelength creates

Energy that helps cure gel products

UVA light is only one able to

Use for curing lights

Fluorescent lamps have a

Slower curing time

LED lamps have a

faster curing time

LED lamps emit light with

Diodes (bulbs)

Wavelength is measured in

nanometers (nm)

Intensity

how much energy is delivered each second onto the UV

gel

Time

The longer the exposure time, the more energy delivered to the UV gel Product

Distance

How close the bulbs are to the nail also determines the amount of energy

delivered to the UV gel

Light-cured gel product will never

cure

100% fully

Hardening

surface is

cured enough to resist indentation

or scratching (Doesn’t have full polymerization)

Improperly cured UV gel is a common

cause

allergic reactions

Curing products to __ is strong and does not cause allergic reactions

90%

E files help prevent

professional from straining their

hands, arms and wrists, which could lead to issues like carpal tunnel

syndrome

E-files are used to

shape, rebalance and remove nail

enhancements and improve speed

Handpiece

holds bits that rotate to file the nail, and contains the motor

Control box

Controls speed and direction of the bit

Electric file bits

Removable abrasive tips

Industry standard size of a electric file bit is

3 /32" (2.38 mm)

Speed in E-files

how fast the bit rotates; it’s important to have a variable speed control to provide maximum control of the file

E-file speed is measured in

RPM revolutions per minute

Natural nails use ____ RPM

2,000-4,000 RPM

Nail enhancements use ___ RPM

8,000-15,000 RPM

Shortening tips of nail enhancements use ___ RPM

35,000 RPM

Torque in E p-files means

the amount of resistance on the e-file while the bit is in motion and in contact with the nail or nail enhancement product

Torque is measured in

Pound per square inch

High torque will keep

the bit spinning evenly when pressure is put on it

Single actions airbrush

Releases the air and paint at the same time

Dual action airbrush

Ability to control air and paint separately, Airflow is varied by pressing down on lever

Gravity fed airbrush

Paint is poured into a small cup on top of the handle

and gravity pulls the paint into the nozzle

Compressor in airbrush is

Source of air pressure needed to push paint out of the gun in a fine mist

Moisture trap in airbrushes is

Reservoir to catch or collect moisture produced by compressed air traveling through the gun

Hose in a airbrush is what

Attaches airbrush to the compressor
