Dear Customer...

Nastroflex strengthens its presence in Denmark From 2011 to the end of 2013, Denmark 3M distributed Nastroflex products, following the acquisition and the subsequent merge with Slipnaxos, former distributor of the Nastroflex group in the Scandinavian country. The non-strategic nature of this business to 3M and the need to provide customers with an appropriate level of service, led 3M and Nastroflex to sign an agreement whereby the


portfolio of customers using Nastroflex products will be under the direct management of the Italian company as of February 1, 2014.

Best wishes for 2014! 2013 was a year full of news for Nastroflex - new products, new quality tools, new collaborations in Italy and abroad, new image - and, above all, it was a year in which we worked to provide end users with the best service and quality. Trusting that what was done in 2013 will bring us all the benefits we hoped for in 2014, we want to wish our customers, suppliers and partners a new year full of satisfaction.

Applications with anti-static products

Do we really know about anti-static abrasives? As part of the rationalisation of its wide range of items for wood, Nastroflex is reviewing anti-static products in particular, which deserve further consideration due to their technical qualities. WHY ANTI-STATIC

PRODUCTS? The sanding process is definitely the main cause for the presence of dust in the wood processing industry (as well as all non conductor materials such as plastics, resins, etc), so much so that the presence

of particularly efficient dust exhaust systems is usually required. However, analysing the process allows to find ways to make sanding dust extraction easier.

The new abrasives designed for metal

Altac X6: lasting performance Altac X6 is a brand-new aluminium oxide abrasive applied to cloth backing and used on metal surfaces intended for chrome plating. It is without doubt the most popular innovation at the moment.

Applications with anti-static products

Do we really know about anti-static abrasives? (from page 1)

It all starts when, during the sanding process, the workpiece, wood chips, the sanding belt and some parts of the machine become electrostatically charged, especially in low humidity conditions. ORIGIN OF CHARGES Electrostatic charges are generated with a simple mechanism: friction between two objects can cause electrons to move from one object to the other; the material that gains electrons becomes negatively charged and the one that loses them becomes positively charged. We all remember how, as children, we would rub a plastic pen against a sleeve of our jumper to attract small pieces of paper to the pen. The amount of electrostatic charge depends largely on the electrical conductivity of materials: good conductors, such as metals, quickly lose their charge, while bad ones can keep it for a long time, even for weeks. When sanding wood, we are dealing with a non-conductive material, precisely wood, which is processed at a certain speed by an abrasive belt consisting of paper, resins and grit, which are non-conductive.

The electrostatic charges that develop on the workpiece and the wood chips have opposite polarities: the workpiece usually takes on a negative charge and the powder becomes positive.

reduce electrostatic charges, such as providing machines with small brushes or metal bars connected to the ground, which still do not solve the problem and are easily worn out by the abrasive.

PROBLEMS GENERATED Some of this dust sticks to the abrasive belt, causing it to "clog" and reducing its removal capacity; another percentage of dust settles on various parts of the machine, in the form of masses that can cause the belt to break, or cover the photocells responsible for adjusting the oscillation of the belt itself, causing it to break as well.

The best way forward is to prevent the development of electrostatic charges and this is why some manufacturers of abrasives, including Nastroflex, have developed various types of anti-static abrasive paper.

Finally, some sanding dust settles on the workpieces that have just been processed, forcing the operator to clean them again before moving on to painting. But the most noticeable phenomenon, since the dust particles have the same polarity, is that they tend to repel each other, and therefore they disperse. Particles that do not stick to the workpiece, to the abrasive belt or to the machine, tend to by-pass the suction drain and disperse in the air. THE SOLUTIONS Various attempts have been made to

Different methods are used to make them and they are often covered by patents, but they basically consist of the addition of substances with high electrical conductivity to the abrasive binders (e.g. graphite which, if used in the outer layer, gives the product a black colour) or to paper. These products are spreading rapidly due to the growing awareness of health in the workplace, the reduced price difference compared to conventional products and, often, a more favourable price-to-performance ratio. In fact, an anti-static abrasive belt clogs more slowly, ensuring greater durability and consistent performance, provided that ambient humidity does not exceed a limit of 50%, beyond which the electrostatic effect doesn't happen.

Naxomax R Antistatic: the evolution of the species From the vast range of Nastroflex products, we point out the evolution of a highly successful product like Naxomax, in its antistatic version called Naxomax R Antistatic. This product is mainly used for sanding compact fibre solid wood, hard and soft wood, and veneers. The innovative aspect of Naxomax R Antistatic is that graphite, which creates antistatic properties, mixed to the first of two layers of phenolic resin binders.

does not exceed 50%, higher performance in term of end result and better cleaning of the sanded piece, thus reducing even the side effects of the electrostatic charge, such as dust attraction and sparks. Naxomax R Antistatic has all it takes to replace competing products, such as Eka 1000, PS23, 1939 e BW114.

Looking carefully, this aspect will become apparent in the form of soft shades that darken the product's original colour. Using a magnifier, you will see a black colour near the abrasive grains. Compared to its standard version and competing products without antistatic substances, Naxomax R Antistatic guarantees, where relative humidity

The new abrasives designed for metal

ALTAC X6: lasting performance surface scratches, quite recurrent when using products with a mineral called "compact grain", which comes in agglomerates or even roughly spherical shapes.

(from page 1)

In the field of coated abrasives, it is quite rare to create revolutionary products. Altac X6 definitely is, because it uses a traditional mineral (aluminium oxide) in a new form.

Altac X6 is used for a process called fine satin finishing on metals intended for galvanic processes, which mainly involves the components for interiors.

A PERFECT SURFACE With its uniform "shell" structure, Altac X6 ensures a higher quality finish for sanded products. Its surface consists of small parts of compact abrasive material, structured in regular geometric shapes that wear

occurs when processing products like aluminium, as well as a good level of finishing, with low Rz values (roughness peaks).

It is particularly suitable for grinding and satin-finishing stainless steel and die-cast aluminium parts, including profiled pieces.

Most users of J859 use medium/fine grain belts over soft contact wheels without grooves.

The belt is often 1-2 cm wider than the wheel itself, which allows users to make the most of flexibility along the protruding edges and work even parts with accentuated curves. Photo. J859 in the processing of alloy wheels for motor vehicles.

The strengths of J859 in the processing of stainless steel include high -quality finishing and product durability thanks to the coolant contained in the resin, which also avoids the typical bluish "burning" resulting from this type of application. As regards the processing of aluminium, J859 features excellent resistance to clogging, which typically

Meetings with industry players

Technical meeting with ICLA Akzo Nobel In recent months, at the headquarters of ICLA (Akzo Nobel group), Nastroflex Sales Managers met with the entire technical and commercial staff from the wood division of the prestigious multinational company, to deal with certain issues of common interest.

This meeting is part of the technical dialogue we talked about in previous issues, which Nastroflex started back in 2010 with many players in the wood chain, with the aim to achieve, through a common pathway, improvements in the processing and finishing of wood pieces, and then offer these

measure the final level of finish (roughness), not only visually but also through appropriate tools. Nastroflex has long insisted on this issue and addressed it in previous seminars, dedicated to users who need glossy finishes. In addition to this aspect, participants agreed on the importance of using quality paints, the composition of which - especially in the balance between fine resins and solid contents has a significant impact on the success of the sanding process and the resulting finish.

Finally, all those present found that users in the industry are showing growing interest in the development of products and applications for alternative and innovative materials, such as PVC and other wood substitutes. The usefulness of the meeting was openly praised by all participants.

Applications on metal using products mixed with additives

Abrasive products with additives against overheating When using abrasives, it is normal for heat to develop. Heat tends to grow as the processing becomes more complex, when it is carried out at high speeds or using coarse grains. Heat and the presence of oxygen also cause chemical reactions which increase abnormalities on smooth surfaces. The effects of overheating on workpieces include the appearance of burn marks, difficult handling and even deformation. The same phenomenon can lead to crumbling or dulling of the abrasive product, thus reducing its life. In response to this problem, the most effective cooling system is undoubtedly the one that provides a flow of coolant (an emulsion of water and oil)

in the work area, which however requires more complex sanding machines, including a tank, a pump, a filter, a collection case and several protections from splashes. In addition, it requires a system for drying the workpieces after processing. As regards abrasives, a solution for dry machining was obtained by introducing some materials called "additives", which feature a special composition to prevent the heating of the metal particles removed and thus facilitate and extend the cutting action of the abrasive product over time. Currently, the most widely used additive is potassium tetra-fluoborate (KBF4), which is applied as a third layer over the two usual layers of

binder resin forming the abrasive surface together with mineral powder. Another additive used is cryolite, a complex salt consisting of aluminium, fluorine and sodium (trisodium hexafluoroaluminate) mixed in the second layer of binder.Compared to the previous additive, it features less effective cooling but makes the abrasive less expensive, avoiding the application of a third layer. The effectiveness of additives reaches its peak with coarse grains, up to P120. However, they prove less effective with fine grains (which are less prone to overheating), since the reduced space between the grains, where the additive can accumulate, forces it to reach the surface, from which it is easily removed.

Useful tips

How to best use zirconium belts When deciding to use zirconium belts instead of traditional aluminium oxide products to get the expected performance, some considerations should be taken into account.

requires high working pressure and contact wheels, preferably 2:1 grooved wheels with cutting tooth, rubber hardness of at least 70째A Shore.

Abrasives that are commonly referred to as "zirconium" are composed of a mixture of aluminium oxide and zirconium oxide. In the Nastroflex range, the most common zirconium-based products are Y986W, R205, Y988D and Y998D.

When using machines with wide belts, conveyor rollers should move at low speed to ensure prolonged contact. When using a product with a high percentage of zirconium, with a soft roller or for manual sanding, the abrasive will tend to blunt after some time and will no longer be capable of breaking down to form a new cutting edge.

The higher the percentage of zirconium (typically ranging from 10 to 50%), the greater the product's ability to remove material from very hard metals. However, there are some instructions to follow. Use of these abrasives

any material. In these cases, there are two alternatives: changing the contact wheels, increasing their hardness, or switching to an abrasive with a lesser percentage of zirconium oxide. Photo. A contact wheel for abrasive belts

As a result, the belt's life will be reduced and, even if the belt still looks like new, the abrasive grains will slip on the piece to be sanded without carving it, therefore without removing Nastroflex News, Jan 2014
