Surface cleaning - Import export

Laser technology is a unique and remarkable tool for architectural restoration and conservation. Laser cleaning has turned out to be the most delicate and efficient way of restoring the beauty of historic architectural treasures, including sculptures, bronze statues, ornate terracotta and the entire façades of buildings. Laser cleaning removes harmful and unsightly deposits without chemical products, abrasives, dust or residues that could pose a risk to humans and the planet.

Practically all types of materials can be marked with laser marking systems: metals, plastics, semi-conductors, glass and ceramic sheets, as well as organic surfaces such as wood, paper and leather. Depending on the intensity of the laser beam on the substrate, the desired marks can be produced by the change of colour, engraving or micro-fusion.

Laser technology can be very precisely adjusted for the surface treatment of metallic materials. This allows powerful, high-intensity laser pulses to be applied to create different types of precise micro structures for visual and mechanical effects.

The process for cleaning precision moulds by laser is an excellent economic, automated and ecological alternative to traditional methods. This ecological process quickly and safely removes stubborn residues without producing chemical or abrasive waste.

Laser is also an excellent way of selectively cleaning surfaces that will need to be treated such as painting, coating, welding, brazing, plastic or metal coating, or joining. In addition, the correct setting of the laser beam allows the substrate to be textured resulting in considerably better adhesion and application quality.

Due to the combination of materials forming them (polymers, glass, metals etc.), composites have complex surface properties. Atmospheric plasma opens the way to a high-quality surface finish as it allows cleaning and activation in a single stage, facilitating processes such as painting and varnishing. As an ecological and efficient technique, plasma is able to replace the most common toxic treatments. Advantages: - Uniform treatment easily integrated into both automatic and manual production. - delicate care of the part to be treated - Easy to implement, rapid treatment - Complete elimination of wet chemical products in the cleaning process - No neutralisation of the waste water, no elimination costs - No heat or steam generated in the workplace - Highly reliable and efficient cleaning process - Marked improvement in hydrophilic properties - Less staff required

The aim of the activation process is to alter the nature of a surface or its energy. More often than not, this allows the wettability of a surface to be increased (by adding polarity) or encouraging the adhesion of a coating (paintwork, ink, glue, varnish). Plasma activation is a simple process that allows a wide range of improvements. Plasma pre-treatment allows, in one single, simple and cheap stage, a significant improvement to the surface to be achieved.
