    new market demands Besides the substrate mix demands also include ever more stringent environmental requirements rising cost pressure and also compliance with specific quality standards and tests of the automotive manufacturers Customized pretreatment boosts production The new Gardo Flex system from Chemetall consists of a large number of high performance modules around the zinc phosphating technology This state of the art process combines the traditional benefits of a conventional zinc phosphating with optimized process components and thus meets modern demands of the global automotive industry For every process step in zinc phosphating Chemetall offers adequate technologies that are coordinated to match each other from cleaning and degreasing to activation and phosphating through to the last rinsing step These modules are specifically combined to suit each individual production line This allows increasing the process efficiency and raising the production yield Modules are selected as a function of the substrate throughput the plant technology available local market conditions and legal regulations Chemetall can thus define an optimal solution for each pretreatment process in cooperation with the customer Modules allow for process economics With the new Gardo Flex system significant process cost economics can be achieved for example by reducing the temperature down to 35 C in the zinc phosphating bath Field experiences have shown that depending on the throughput energy costs in the six digit range can be saved All process elements are optimally aligned and together with a distinctly longer bath service life meaning lower water consumption and smaller effluent volumes contribute to the resource saving aspect of this technology The reduced coating weight and finer crystal formation on the metal surface require less replenishment solution and thus lead to a reduction in the chemicals consumption To give customers further benefits with regard to bath service lifes and maintenance costs Chemetall in addition also offers an effective demulsifying operation of degreasing baths The Gardo Flex technology can be used in existing plants and usually does not require any alterations of the plant Expensive cooling for activation or rinsing baths to suppress the formation of a phosphate coating on aluminum substrates is no longer required as the aim is to generate thin coatings No limit for aluminum For some years already the lightweight material aluminum has been gaining ground in automotive manufacture Up to 70 per cent are pretreated in the production plants of the automotive manufacturers a fact that may lead to technically most demanding application when using conventional zinc phosphating processes Gardo Flex by contrast is suited for multi metal applications without limitations This modern technology can be used for all standard metal materials used in the automotive industry No limits exist for the throughput of aluminum substrates and even non galvanized steel can be treated without any problem The process thus offers high flexibility with regard to the utilization rate of the customer s production plant On aluminium substrates Gardo Flex ensures a reduced pickling loss on the metal surface This significantly minimizes the consumption of fluoride containing additives

    always depends on how the raw materials were initially processed And so glass too has a past life everybody knows that luck and glass shatter easily and luck can rust easily but glass Dr Michael Emonds considers the possibilities The surface of freshly produced float glass is highly reactive While the glass is being stored or transported it may react with humidity that has penetrated the spaces between the layers of glass which can lead to highly adhesive blotches of corrosion If the corrosion is distinctive the glass cannot be processed any further The level of corrosion depends on the humidity temperature conditions of storage and transport and the quality of the glass composition hydrolytic class etc Furthermore corrosion in the early stages is not recognisable to the eye and only becomes visible when the glass is processed further eg by low E coating silvering or tempering In the Chemetall development laboratory corrosion protected sheets were compared to non protected sheets as to any reactions following application of a thin film coating figure 1 In stress tests the untreated sheets showed signs of flaking much sooner than sheets that were given an initial protective coating The disturbance in film build up that was responsible for this can during further processing into insulation glass also have a negative effect on the sealant on the glass surface Much can be done to protect glass from corrosion but it is not possible to exclude it completely While corrosion in the initial phases can be removed using suitable polishing agents visibly corroded glass can no longer be repaired to a reasonable standard As float glass available on the market can vary eg they can possess various hydrolytic qualities or the year of manufacture may simply be different polishing in order to clean the surface of the glass is surely a reasonable step to take prior to further processing of the glass into a higher quality product It must be pointed out once more that due to initial corrosion defects on the glass surface will be increased which may not become visible for some time after the end product has been completed unless silver layers start to flake off colour defects of low E glass or adhesion problems with insulating glass occur Chemetall s experience shows that corrosion can be reliably held back using tailor made anti corrosive interleavants However one must remember that the corrosion protection must be totally washable leaving no residue prior to further treatment The same applies to all other auxiliary agents such as cutting fluids separating agents or coolants and of course contamination of the glass surface due to dust fingerprints roller prints gloves etc This is no longer possible using just water alone special detergent used for treating glass is also required It must also be possible to wash this off completely To read the full article please click here This article has been published in the GLASS WORLDWIDE issue sixty one 2015 About Albemarle Albemarle Corporation headquartered in

    sheet thicknesses are largely constant in the field of agricultural and construction machinery the pretreatment technologies have to generate constantly good results on thin sheets in the same way as on extremely thick sheets on hot or cold rolled or on scaled steel This requires a high flexibility of the pretreatment technology and also of the subsequent baking process The different sheet thicknesses also lead to different reaction times Here care must be taken that thin sheets do not remain in the furnace for too long as otherwise there is a risk of paint embrittlement Reliable and suited for multi metal treatment Since the manufactures of agricultural machines nowadays also pay attention to a reasonable weight reduction a varied mix of materials is now common in this sector Although the axles cross members and heavy duty components continue to be produced from cold rolled hot dip or electrogalvanized steel light weight materials such as aluminum or magnesium alloys are also gaining ground This is why a state of the art pretreatment technology is characterized by its ability to flexibly react to such varying metal compositions Phosphating plants only offer limited flexibility as they require sometimes considerable setting up times The Oxsilan technology is suited for multi metal treatment Within just a few minutes time the baths are readjusted by adding products and special silane additives All standard metals such as steel stainless steel aluminum or magnesium alloys and cast steel can be pretreated in such baths in quick succession Comparative tests with various metal substrates demonstrate that Oxsilan affords the same corrosion protection as traditional technologies Test panels exposed to 24 month weathering with additional regular salt spraying show no differences The phosphate test panel of a cold rolled steel sheet even exhibited slightly stronger creepage Fast and simple analyses The chemistry of the Oxsilan technology is extremely robust This notwithstanding here too the baths require regular controls After all the bath conditions are subject to constant changes due to metal dissolution carry over and the actual substrate consumption Unlike phosphating this does not require time consuming manual titration free acid total acid or Karl Fischer Nearly all analyses can be performed directly on site using portable meters measurement of the electrical conductivity pH and fluoride content already gives a largely accurate picture Like with the phosphating technology the ICP analysis inductively coupled plasma can provide an analysis of all metal ions The quickest method for checking the coating quality is by means of an x ray fluorescence analysis XRF of the pretreated substrates The corresponding mobile XRF meters provide the results almost online and thus allow for a timely reaction in case of quality problems Technical economic and ecological benefits The Oxsilan process is free from hazardous heavy metals such as nickel or chromium As a result time consuming bath cleaning and expensive disposal of poisonous phosphate sludge are no longer required Since the process takes place under milder conditions the treated metals are barely corroded Per square meter
