Machinery identification

If you need technical assistance, spare parts… Contact us referring your machine and its serial number. You can find this information in the operator’s manual and the identification plate in the electric cabinet.

Equipment warranty

Machinery and devices manufactured by BCB have a warranty year (from the delivery date) against all manufacture or working defects. Warranty not includes the damages produced by a wrong use or lack in maintenance.

The components that are not made by us, will enjoy the guarantee granted by the manufacturer.

What is ultraviolet radiation?

UV light or ultraviolet radiation is a part of the electromagnetic spectrum below the visible light, with wavelenghts from 180 nm to 400 nanometers. It’s classifies in three ranges according their effects: UV-A, UV-B and UV-C:

UVA – From 320 nm to 400 nm, where visible lights begins. This radiation is capable of penetrating any substrate (paper, inks, coatings..) and in used frequently in the industry in deep curing processes. Our skin has developed UVA ‘control mechanisms’, and therefore is not very harmful if the doses are not superior to, for example, a normal exposure to sunlight. But we must remember that this radiation ages the skin.

UVB – Is defined as the radiation between 280 and 320 nm. In spite of having a major energy than UVA, it does not penetrate so deeply, but it produces curing faster. Our skin is not well protected against the UVB radiation due to the fact that only a small quantity comes to us across the ozone layer. The radiation UVB ‘burn’.

UVC – This is the section between 200 and 280 nm. This is a high-energy radiation that falls as soon as collides against any surface. Therefore in the industry is used to cure surfaces. Life on earth has no protection against UVC and therefore is highly dangerous. However, as a result, is widely used in germicidal applications effectively removing bacteria and viruses.

What are we talking about when we say UV curing?

UV curing is the process of polymerization of materials by exposure to ultraviolet radiation. The traditional drying is evaporation of moisture or solvents by oxidation, they are practically absent in the UV, so the more accurate definition would be ‘UV radiation curing’. In spite of the foregoing, the term ‘ultraviolet drying’ is a universally accepted term in the technical world.

Precautions working with ultraviolet radiation

The advantages of UV curing processes (speed, high gloss, hardness, absence of solvents, etc.), as well as any industrial process, can only be used taking into account the use of appropriate precautions to ensure a healthy and safe work. 

As a basic premise we must start with the fact that UV radiation has high eritemal effect (ability to blush and/or burn the skin). A prolonged exposure can have a cumulative effect on the cellular DNA, for that, is MANDATORY avoid looking directly at any ultraviolet emitter active, even for short duration to UV radiation.

What is an UV lamp? How it works?

The electrodes draws an electric arc between them, generating light once the gas is ionized. 

This arc defines the useful width of curing of the lamp.

Useful life of a UV lamp. Why change it when it is still in perfect condition?

The length and use depends of its doping and manufacture. We advice a good cleaning and maintenance of the equipment and ventilation system to ensure its life and prevent premature aging. 

Uv lamps have a constant wear that is increased exponentially once it reaches the recommended duration. Depending how is working this lamp, its duration will last more or less, influencing the conditions of the environment such as temperature, pollution, etc.

How should I replace the UV lamp?

This process may vary depending on the machine. See the operating manual of your equipment. Due to some components are harmful to the environment, exhausted or broken lamps should be disposed according to current regulations in your area.

What means infrared?

IR or Infrared radiation as the ultraviolet or the visible light is a portion of the electromagnetic radiation, ranging from 700 nanometers (beyond the visible light) to 10000. It is classified into several divisions, depending on their length: short wave, medium or long.

Infrared drying

This is the use of infrared light to dry inks or coatings in industrial processes. It consists in evaporate water of those materials by heating its surface with the IR emitters.
