Introduction ceramic foam ZIRCOFOAM

The ZIRCOFOAM Ceramic Foam replaces many applications of mineral wool but with theeasy to use and speeds typical of polyurethane foams in an employ range from -20C to1100C. Zircofoam have an instantaneous hardening makes it suitable for injection directlyon site or used in injection molding process. With a special pneumatic nebulizer can beused for spray application.

Zircofoam is designed to be used repeatedly operating with small waiting times, togetherlayers for injection spray you get a consistent manufacture.

The release of the product can be done manually with coaxial cartridges and special ma-nual or pneumatic dispensing guns. Mixing is obtained through the use of disposable staticmixer. Attention : during the preparation phase by shaking the product for at least 30rounds to allow suspended particles to a perfect distribution in the solvent.

The minimum thickness recommended by injection into a cavity is 10 mm, with thicknessless than you would have difficulties to penetrate the product to the bottom without beinghindered by the walls; for the spray application is recommended to operate from aminimum thickness of 1 mm to a maximum of 10 mm, thicker than is advisable forinjection.

The volumetric yield of the product is approximately 3:1 from a cartridge of 380 ml andthen you get 1.15 liters of ceramic foam, approximately 1 square meter of sprayed surface.

The curing time it's few seconds, then, there is a partial cure in which the material expelsmoisture free and strengthens the molecular bonds in a time ranging from 24 to 72 hours.

The complete polymerization of the material is obtained in 3 days per cm of thickness whe-re the material reaches the full of its own characteristics. is possible and advisable to shor-ten these times, however, subjecting the material to heat treatment by performing the firstheating ramp following a gradual increase in temperature, are sufficient for 50 C for 30-min for the first inch of thickness and other curing at 180 C for 30min cm thick for com-plete polymerization. After that, the material can be subjected to intense heating.

Zircofoam during the first heat will dry completely free from moisture (104 C) and water-related at the molecular level (175C) releasing water vapor. At the temperature of 313Cwe have a release of carbon dioxide due to pyrolysis of the organic binder contained in theceramic matrix (about 2% by weight) at this temperature, the ceramic foam take a gray co-

lor due to the presence of carbon particles in the ceramic body; at temperatures above 50-0C is the complete combustion of carbon particles by returning to a cream color pottery tobecome yellow at temperatures above 900C (sintering).

Warning: Zircofoam items may incur in deformations and cracks in the ceramic body if wassubjected to intense heat without having waited for the complete drying.

Recommendations for use

Metallic materials

Its important to remove any grease from the surfaces to be treated either by injection ifyou want to spray to ensure good adhesion of Zircofoam. Dust, rust and moisture in

principle no problem, and the adhesiveness of the foam ceramic is also good on thesesurfaces.

Zircofoam has an excellent adhesion on steel, stainless steel, galvanized steel, titanium.Good adhesion on copper, bronze and brass. Low adhesion to aluminum and aluminatesteel, which in this case can be increased after surface grinding with abrasive paper.

For painted surfaces it is recommended that a preliminary test to assess the degree ofadhesion because the paint on most of the ceramic foam has little power to member-ship, in this case we will require the complete removal of paint until you get to bare me-tal.

The temperature of the surface that must be applied Zircofoam must be between -5 Cand 150 C, at higher temperatures is not recommended for use in the early stages ofpolymerization occurs a release of highly flammable gases and vapors (ethyl acetate,acetylene) from the danger of self-injection and subsequent ignition of gas.

Building materials

Its important to remove any grease and paint from surfaces to be treated either byinjection spray if you want to ensure good adhesion of the ceramic foam. Dust, mold and

moisture in principle no problem, and the adhesion of the ceramic foam is also good onthese surfaces.

Zircofoam has an excellent adhesion to concrete, mortar, bricks, refractory materials,stone materials and all materials of mineral origin in general.Good adhesion to woodand wood products.

For painted surfaces require the complete removal of any paint and substrates of lowconsistency through the use of metal spatulas or brushes.

Zircofoam have a very low water vapor barrier and thanks to the large exchange surface

increases the ventilation of the building by implementing the dispersion of moisture tothe environment. The high resistance at moisture and mold makes Zircofoam suitable foruse on surfaces subject to deterioration.

The temperature of the surface that must be applied to the ceramic foam must bebetween 0 C and 150 C. It is not recommended for use higher temperatures becausein the early stages of polymerization occurs a release of gases and vapors of solventshighly flammable (ethyl acetate, acetylene) and danger of self-injection and ensuing firegas.


11/16

Fibrous materials

Excellent adhesion to mineral wool, glass fibers, mineral fibers, plant fibers in general. Goodadhesion to plastics, non-compact fibers.

Plastic materials

Adhesion grade almost absent. It was found a certain stickiness than plastics that have acertain affinity with water (nylon), obtained by following a particular process of preparation.

Spray applications:

small parts for industrial use. (1) Welding head forsealing plastic with complex geometry;

pipes, valves and fittings of industrial and domestic use(2);

heat insulation of metal surfaces in general (3); fibrous materials: containment effect; to eliminate the

effect dusting under air flowing effect or to make easiermaintenance operation (4);

Just one layer of 1 mm to lower the surface temperature of30% (depending on environmental conditions), for example,on piping hot water at 60C with ambient temperature of 25Cin still air, after applying a layer of 1 mm ceramic foamproduces a surface temperature of 38C, for example, or on ametal surface with a temperature of 240C, ambienttemperature of 18C in still air after application a layer of 1mm ceramic foam produces a surface temperature of 165C.

Applications on-site by injection :

Thermal insulation for filling cavities (1) Quick repair masonry refractory furnaces or

fireplaces (2) Pipe insulation (3) Injection moulding various items (4)

There are some examples of reduction of temperature withthe use of ceramic foam in filling a gap.

Ceramic foam thickness = 2 cm, hot face temperature100C to 36C cold face; hot 200C to 53C cold face; hot350C to 83C cold face; hot face 400C to 95C coldface; hot face 500C to 124C cold face.

Ceramic foam thickness = 3 cm, hot face temperature100C to 30C cold face; hot face 200C to 47C coldface; hot face 350C to 62C cold face; hot face 400C to73C cold face ; hot face 500C to 87C cold face.

Ceramic foam thickness = 8 cm, hot face temperature 850 C to 88 C cold face.

Example : we have an oven built with a multilayer wallwhere 3 cm thick refractory bricks + 100 mm ceramic foam

injected + 2 mm galvanized steel + 1mm ceramic foamsprayed on the outer surface will have a temperaturedifference of more than 1000 C. We have a temperatureinside the furnace chamber to 1100 C and the outer wallsurface of 60 C.

Safety advice :

Always use Zircofoam in ventilated ambient : danger of forming an explosive mi-xture due to evaporation of solvents and gases blowing (present only during the

early stages of expansion and hardening). The ceramic foam it's not toxic, but itis essential to use protective devices to prevent irritation to eyes, skin and respi-ratory tract. The smell is due to small emissions of solvents such as ethyl acetateand acetic acid (about 15 g per liter) and expanding gas (acetylene). This odorwill decrease and disappear in a few hours to totally dry.

Zircofoam ECO its a spray-on ceramic foam was crea-ted as coating of metals and building materials to offer

an insulanting material in combiantion of depollutingproperty in a temperatures range between - 20 C to700 C.The innovative feature of this ceramic foam it's thestrong resistance to moisture, weathering and normalmechanical stress , jointly the property offered by aparticular cristalline form of titanium dioxide (anatase)as catalyst to split some complex organic molecules inelementary form, or with redox reaction of nitrous oxi-des and water to obtein nitrates. All taht thanks to pho-tocatalysis property of Anatase under UV beams. WithZircofoam Eco we have increased the efficiency of thisprocess thanks to high exchange surface offered byceramic foam morphology
