UV curing is adaptable to printing, coating, decorating, stereolithography, and in the assembly of a variety of products and materials. UV curing is a low-temperature, high speed, and solventless process as curing occurs via polymerization. [2] Originally introduced in the 1960s, this technology has streamlined and increased automation in many ...
The next type of curing light developed was the quartz-halogen bulb; [4] this device had longer wavelengths of the visible light spectrum and allowed for greater penetration of the curing light and light energy for resin composites. [3] The halogen curing light replaced the UV curing light. The 1990s presented great improvements in light curing ...
UV LED Nail Lamp. Featuring a near-perfect rating on Amazon and over 49,000 customer reviews, this best-selling nail lamp uses a built-in sensor and adjustable timer to cut down on drying time.
A 175-watt mercury-vapor light approximately 15 seconds after starting. A closeup of a 175-W mercury-vapor lamp. The small diagonal cylinder at the bottom of the arc tube is a resistor which supplies current to the starter electrode. A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce ...
Halogen lamps with fused quartz envelopes are used as inexpensive UV light sources in the near UV range, from 400 to 300 nm, in some scientific instruments. Due to its black-body spectrum a filament light bulb is a very inefficient ultraviolet source, emitting only a fraction of a percent of its energy as UV, as explained by the black body ...
A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. [1] These changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light.
UV-B lamps are lamps that emit a spectrum of ultraviolet light with wavelengths ranging from 290–320 nanometers. This spectrum is also commonly called the biological spectrum due to the human body's sensitivity to light of such a wavelength. [1] UV-B light does not tan the skin very much, compared to the UV-A lamps that are used in tanning beds.
The completed cans are sent to the UV oven, that operate over 100 F and contains between six and eight 300 watt/inch UV lamps. Both inside and outside of the can are exposed to the light to ensure proper ink curing.
