UV ovens
UV Ovens
Since 1970 Photo Electronics has been designing and manufacturing ovens for UV Curing and therefore has considerable specific experience in the use of UV technology applied to stone materials.
The company offers a wide range of UV ovens for curing and hardening mastics, resins and one-component putties, which adopt the best existing technologies and solutions. In the lining, grouting and surface finishing processes, single-component products are mainly used, which harden thanks to the ultraviolet rays emitted by special lamps.
Photo Electronics uses high pressure UV lamps with very high ultraviolet rays in its ovens, which allow you to make the most of the advantages offered by single-component products.
Metal Halde lamps instaled are available in 3 different UV radiations. for a perfect compatibility with the various types of resins available on the market.
Photo Electronics can recommend the ideal version of lamp to be installed, accordingly with the filler/resin used.
The operating principle of UV systems
The single-component mastic isn’t hardened by exposure to heat, but with invisible electromagnetic waves called UV rays, generated by special UV lamps.
The mastic applied on the surfaces of the raw material only hardens when the UV rays irradiate the surface and penetrate into the material.
Before going into the oven, the mastic remains in a liquid, semisolid or solid state just as it was in the tin, and can be worked and moulded at ease by the operator.
The temperature of the environment and the material has no effect on the hardening.
Then the material goes into the UV oven for “UVCuring”. During this process, the product starts to harden rapidly and the process takes just 30/40 seconds.
When the material comes out of the UV oven, the fully hardened surfaces can be polished immediately.
The single-component UV product doesn’t require an hardener. The product hardens
in just 30 seconds.
UV ovens are extremely compact and can be installed in existing lines.
