Description of anodising process
Anodising produces a high-quality finish which resists corrosion, abrasion and exposure to industrial, marine and other severe environments. The choice of either clear or coloured anodic films varying in thickness from 10 to 25 microns, covers a diverse range of applications. The aluminium fabricator, builder or architect can select the natural lustrous clear anodised finish or incorporate any of the wide range of coloured finishes. Anodising is an electrolytic manufacturing process that makes it possible to build a heavy inert oxide film INTO the metal surface.
Aluminium is placed in an electrolyte, (acid/water solution) and an electric current passed through the aluminium which becomes the anode (positive terminal). Under the influence of the electric current, oxygen forms on this anode and immediately produces a porous oxide film on the aluminium surface. Extending the duration of this process increases the thickness of the anodic film.
Once the required thickness of the anodic film is obtained, the aluminium is removed from the electrolyte and “sealed”. Sealing is carried out using hot de-ionised water, steam or room temperature nickel fluoride solution. A reaction occurs between the water (or steam) and the porous oxide film. The resultant film is smooth hard and translucent.
The new Anodising Standard (AS1231) was released on 19 Juy 2000. The standard specifies requirements for anodic oxidation coatings on aluminium and its alloys for general application and for external architectural applications.
Clear anodised is the original process developed that enhances the surface appearance. Clear anodising is often called natural, satin or silver.
Ideal for interior applications such as partitioning trim, suspended ceilings, etc. Kolona is an anodic film thickness of 10 microns and should not be used in external applications.
A high quality tough finish developed in strict accordance with AS 1231.2000. Optimal film hardness is established to ensure extra-long life and abrasion resistance. As colour is not dependent on the anodic film thickness the most economic film can be specified for the particular application.
The colours for both Kolona and Anolok are produced by the same electrolytic deposition technique. Stable inorganic metal/oxide pigments are “locked-in” at the base of the anodic film prior to “sealing”. Hence, when surface abrasion occurs, the colour is protected by the hard-transparent anodic film above. As the colour is created by inorganic metal/oxide pigments which are permanently stable and unaffected by ultra-violet radiation, the finish is colour fast and will not fade.
As with timber, brick and other traditional building materials, no two pieces of anodised metal look exactly alike. Slight colour variations are inherent in all colour anodising processes.
Description of powdercoating process
Aluminium’s good resistance to corrosion and its ability to develop a natural protective oxide surface film, contribute to its outstanding properties as a base for organic coatings.
When the metal is properly cleaned, deoxidised where necessary to remove objectionable residual oxides, then chemically treated to convert its surface to an inert film, it provides an ideal substrate for such finishes.
Thorough cleaning of the aluminium surface and its proper chemical pre-treatment are always of critical importance.
In most cases, a five-step pre-treatment process is used. Firstly, a thorough clean and etch is used to remove such contaminants as coolants, fingerprints and general shop dirt.
After the metal is rinsed, a chromate conversion coating is applied before passing through two more rinsing processes, the last one having the total dissolved solids content adequately controlled so no residues are left on the aluminium.
The metal then passes to the spray booth where banks of electrostatic spray guns reciprocate the full height of the booth. This ensures all critical faces and edges have an even coating of powder. The electrostatic charge serves two purposes:
- By charging the powder, it is attracted to the nearest non-charged surface, this being the object to be coated.
- It forces the powder particles to repel each other, similar to the like poles of a magnet, thus aiding atomisation.
The excess powder that has not adhered to the substrate is removed from the booth by a sophisticated vacuum system. It is then cleaned and re-used.
The powdercoated metal moves out of the booth into the baking oven where the powder fuses and cures to a durable finish.
Powdercoating produces colours which are consistent, have an excellent finish and the system has superb covering characteristics even on complex shapes such as the extrusions.
The powders are available in two grades, depending upon the application.
- Standard polyester powders are the products most commonly used, with a service life of up to 10 years.
- High durability polyester powders have higher grade resins and pigments and offer a service life of up to 15 years.
- PVF2 fluorocarbon wet paint coatings are available in a limited range of colours and gloss levels. They are also available with a metallic appearance and have a life expectancy I excess of 25 years.
It is recommended that glass be protected from contamination caused by building materials and methods during construction as this will greatly simplify the glass cleaning task at the end of the project. If the glass is not protected during construction then the glass and frames should be cleaned frequently during construction.
Construction dust, leachate from concrete and rusting from steel can contribute to the formation of mild chemicals, which may stain or otherwise damage the glass. Glass installations which are adjacent to concrete (e.g. concrete slab floors) require extra care and cleaning due to the abrasive nature of concrete dust. Temporary screens should be installed if welding, sandblasting, floor sanding, cuffing or other potentially damaging construction practices takes place near the glass.
Extra care is necessary where high performance reflective glass is installed. The coated surface can be susceptible to stains and scratches and therefore requires vigilance during the full construction process. Some tapes or adhesives can stain or damage glass surfaces. Avoid using such materials unless they are known to be easily removed.
All tradesmen should be advised to be aware of damaging glass and windows and to leave in place any materials protecting the window or glass. Do not store or place other material in contact with the glass. (This can damage the glass or create a heat trap leading to thermal breakage).
CARE AND MAINTENANCE
ALUMINIUM PAINTED AND ANODISED
The majority of the aluminium supplied for architectural products has its natural erosion resistance further enhanced by additional surface protection. These finishes produce a surface that is both attractive in appearance and low in maintenance. Alliance Windows extrusions and products have been designed and produced using premium grade components and materials to ensure extended product life with minimal maintenance.
The products made from this material being in a finished condition require suitable packing to prevent damage from abrasion during delivery. On site, they should be stored in a clean dry area away from cement, lime, paint, acid etc. During installation, they must be protected from building fall-out such as wet plaster, mortar, paint and welding splatter. Wet plaster and mortar should be removed immediately and the soiled area washed down with clean water. Acid used for cleaning brickwork must be prevented from dripping onto aluminium. Should this occur, the acid must immediately be washed off with clean water.
If strippable coatings or pressure sensitive tapes are used to protect5 exposed surfaces, care must be taken not to damage the finish during their removal. Prolonged exposure to sunlight can make them increasingly difficult to remove.
The basic requirement is to keep the system clean and free from deposits which may hinder the operation and appearance of the system.
Both painted and anodised finished surfaces should be regularly washed down with water to maintain their appearance. The aluminium frames of windows and doors should be washed whenever the glass is cleaned.
Cleaning is desirable if the fine finish of powder-coated aluminium is to be preserved. Deterioration of the coating occurs mainly as a result of grime deposition and attack by contaminated moisture, which in a coastal environment contains chlorides and sulphur compounds. Deposited grime absorbs contaminated moisture like a sponge and holds it against the powder-coated surface; this permits the attack to proceed thereby damaging the coating, which cannot be restored without removal.
The frequency of washing is determined by the desired appearance of the structure and by the local environment but should occur every 6 months. Areas close to the coast or subject to industrial fall-out and having limited rainfall require more frequent cleaning i.e. every 3 months.
A cleaning log of frequency and dates must be kept in order for the warranty to remain valid.
Where regular maintenance does not remove all the dirt which may be adhering to the surface, the following procedure should be followed:
Wash with warm water and a non-abrasive kitchen detergent, using a soft cloth or a soft bristle brush. To prevent shiny spots do not press too hard and to minimise streaking wash from the bottom up. Rinse with fresh clean water immediately afterwards to remove all traces of detergent.
Washing as recommended for paint finish should be first tried. If this does not remove all dirt build-up, a solvent cleaner such as kerosene, turpentine or white spirit may be used. Failing this, mild oil-base abrasive car cleaner or mild soap-based abrasive bath cleaner can be used. Thoroughly rinse and dry with a soft cloth after cleaning.
A coat of liquid wax may be used to enhance the gloss finish.
Do not use highly caustic or highly abrasive cleaners on any type of finish
Do not use solvent cleaners on paint finishes.
- To avoid the possibility of corrosion, only aluminium, stainless steel or galvanised steel fasteners should be used for fixing aluminium.
- In a marine environment, stainless steel fasteners must only be used.
- Water running off copper or lead roofing or flashing materials may have a corrosive effect on aluminium. Avoid installing copper or copper alloy products if water may run from them onto aluminium.
- Insulate and protect aluminium for unseasoned timber as the sap can cause stains which are almost impossible to remove.
- Aluminium products should be isolated from permanent contact with mortar as corrosion can occur. Caulking gaps between frame and wall or aluminium angle trims are preferred for contact rather than the frame member.
Flexible profiles such as PVC, Neoprene, Santoprene, EPDM etc. are used for glazing gaskets and weather seals.
Initial installation will be assisted by a smear coating of a lubricating solution such as Dow Corning Emulsion No 8 (available from Ajax Chemicals) and weather seals should be treated with the same solution in service i.e. 6 monthly.
Operating hardware such as pivots, locks, rollers and rotating handles should be checked for tightness of fixing screws and lubricated six monthly with a spray-on product such as silicon spray.
Installation on or close to the coast should be lubricated more frequently.
The bottom rollers are produced from self-lubricating nylon and rotate on stainless steel shoulder pins. As noted previously no additional lubrication is required but it is important not to allow the build-up of dirt, which may impede the operation of the roller.
It is recommended that cleaning is carried out using a soft brush and/ or vacuum cleaner at regular intervals of 3 months.
It may be necessary to thoroughly rinse tracks with water after cleaning, especially where crevices are present to ensure removal of all residues.
A cleaning log of frequency and dates must be kept in order for the warranty to remain valid.
Glass should be cleaned using only cleaning materials which are free of grit and debris (to avoid scratching and marking of the glass surface). Only detergents and cleaning solutions which are recommended for cleaning glass should be used. Mild detergents are preferable. Abrasive cleaners, powder based cleaners, scouring pads or other harsh materials should not be used to clean windows or other glass products. Do not use cleaners which contain Hydrofluoric or Phosphoric acid as they are corrosive to the glass surface. Do not clean the glass when the glass is hot or in direct sunlight.
Avoid causing extreme temperature changes to the glass as this may lead to thermal fracture of the glass, i.e. do not splash hot water on cold glass or freezing water on hot glass.
