InterWet provides solutions to replace metal in heavy-duty parts
Polieco successfully developed another industrial application for the Cannon InterWet technology: heavy duty manholes made by the co-injection of rigid Polyurethane and chopped glass fiber can replace the conventional steel and cast iron ones, with numerous advantages.
The InterWet technology features numerous interesting references in several fields of the industry, from transportation to industrial air conditioning The products developed by the Italy-based POLIECO stand for their originality and final use: round, square and rectangular manholes are manufactured at a very serious daily rate using a complete production island supplied by Cannon Afros.
The InterWet technology is the most suitable solution for producing glass-reinforced Polyurethane parts with complex shapes.
Attractive manholes made with Glass-reinforced Polyurethane are now commercially available
This allows the handling by one only man, fully respecting the safety laws that limit to 25 kg the maximum weigh of handled goods.
Several other advantages characterise these polymeric manholes: ·
of up to 40 Tons ·
Solidity and resistance: a standard model can stand the weight Electric insulation: it protects pedestrians from accidental
electrical shock in humid or wet environments and presents little interference with the radio frequency, satellite or cell phone signals
of modern transmission systems. ·
road traffic, avoiding any acoustic disturbance to the inhabitants. ·
Environment protection: the CO impact of a polymeric product is several times lower than that generated by a traditional
stations, also because they are completely spark-free. ·
Customization: the frames or the covers can be produced in different colours for different utilities/applications, personalising the upper part of the cover with the name of the customer,
metal casting operation, resulting in a "Greener" product. ·
service or sponsor. ·
Last but not least, these synthetic products are not appealing
for the thieves that steal and resell the metallic ones to the scrapyards!
Characterised by an attractive look and a perfect surface finish, the manholes manufactured under the KIO tradename are moulded is several shapes, dimensions and functions. Conventional flat covers or holed grills can be produced in sizes from 400x400 mm up to 700x700 mm or 800 mm diameter for the round ones.
Their main advantage towards conventional products made in steel or cast iron is their lightness, which makes the operations of installation and maintenance easier and safer: the weight of the KIO covers is 70% lower than the weight of European made cast iron ones!
STRUCTURAL ELEMENTS FOR THE
CONSTRUCTION INDUSTRY After the application of the adhesive the slabs go to the glass fiber application area, where a precisely cut-to-size piece of bi- directionally oriented glass fiber mat, is simply laid over the rigid support. A tooled antropomorphous robot then carries out the squeegeeing operation, to fully wet the glass mat with the still creamy Polyurethane adhesive, to ensure top bonding and to prevent any air spots from being left. Then, the curing step to harden the bonding agent is made in a vertical stacker/drier. The product stops here for several minutes, then the protective film is removed and the finished slab is loaded automatically on the unloading tray.
Two types of products can be obtained with this process: · LAMINA 3+, a 3 mm ceramic slab with a glass fiber structural reinforcement, for a total thickness of 3.5 mm.
· LAMINA 7, a sandwich of 2 Lamina 3+ with an interposed glass fiber mat applied with Polyurethane adhesive. Its physical features allow to pass the car crashing tests recommended for ventilated façades.
A triple laminate is also produced for special heavy-duty applications.
A single line can manufacture 70 standard slabs per hour, while the more complex one can produce up to 35 double and triple slabs per hour.
The stacks of finished slabs are brought to the central storage, where they stay parked until they are requested by the order processing software for a customized delivery. When tiles are ordered in sizes smaller than the large 3,000 x 1,000 mm, the slabs are sent to the automatic Laser-cutting area.
Noise reduction: these covers do not «clang and rattle» under Resistance to corrosion and to chemical agents: they are not
subject to rust, corrosion, condensate. They are particularly suitable for seaside resorts, food and chemical industry and petrol
The manholes can be easily personalised
The capacity of every press is from 150 pieces per day for the smallest square model to 100 pieces per day for the largest round one.
POLIECO is now planning to produce covers with a coloured surface, and to increase the range of products to new models and sizes. Cannon Afros will be happy to assist them further during this ambitious project!
Polyurethane-based KIO manholes are rust- and corrosion-free
These products are 70% lighter than the metal ones!
The Cannon equipment - one high-pressure metering unit and FPL InterWet head, the glass-dispensing system connected with the robot manipulating the head, two presses and all the relevant controls and safeties - started in December 2011and is now producing on three shifts for five days per week.
Various sizes and shapes are available
Being 3 m and just 3.5 mm thick, LAMINA can be used in the building sector to cover indoor and outdoor surfaces, new and existent walls and surfaces, ventilated and curtain walls, insulated walls, partition walls, tunnels and undergrounds; it can also be used in the ship building sector and in the healthcare, hospital and medical sector. Thanks to its lightness and excellent aesthetic quality, LAMINA is the perfect solution to enrich interior design projects and give life to new applications in bathrooms, kitchens, on cupboards, tables, desks and furnishings in general. LAMINA is the first surface that combines reduced thickness with large format, high resistance to mechanical stress, chemical attacks, scratching, deep abrasion and bending.
PRODUCT PERFORMANCES 2
The advanced technology adopted to produce the slabs makes them easy to clean and sanitise and resistant to frost, fire, mould and UV rays without altering colour, specifications and properties. LAMINA is the first graffiti proof ceramic surface; it is easy to clean and even the strongest paints can be easily removed.
The project jointly developed by Cannon and System Lamina has generated a Composite laminate characterised by outstanding mechanical and aesthetic properties. System Lamina welcomes inquiries concerning their turn-key package, that can be licensed worldwide to manufacturers of ceramic gres decorative tiles.
Cannon is proud of having once more cooperated with an innovative Company for the definition of new standards in a competitive field as it is the ceramics one, and will gladly discuss the needs for the application of Polyurethane, Silicone and Epoxy resins in difficult end uses.
7 LAMINA is available in a wide range of surfaces, colours and textures
