Description; Kerapour is a cellular insulation material. It has an exceptionally high strength to density ratio and can be used as a structural member rather than just a filler. It has very low thermal conductivity due to its very fine structure. Kerapour has very low permeability due to its closed porosity. Kerapour is very easily mixed to a pourable consistency with +32% water, and flows right into the furthest corners, self-leveling.

Temperature C.C.S Density Porosity P.L.C Conductivity
110oC 11.2MPa 1.1 50% 0%  
400oC 11.9MPa 1.02 -0.38% 0.28Wmk  
800oC 11.7MPa 0.99 -0.38% 0.34Wmk  
1000oC 12.7Mpa 1.06 61% -0.90%  
1300oC 18.0Mpa 1.07 58% -3%  

Note; From the above data it is clear that Kerapour is exceptionally stable.

Particle size distribution; Very fine; 90% -0,85mm

Chemistry; Aluminosilicate.

Installation; Use 1,1tons per cubic metre. Mix with +32% water and pour it. Mixing can be done by hand in a bucket.

Applications;: All insulation applications, especially where structural strength is an advantage, or installation is difficult or impermeability is desirable.

ISCOR pilot plant code; QJO

KERAPOUR DEMONSTRATION

1. FLOW

Mix 500g Kerapour with 160g water to give a highly viscous ball, which flows slowly but continuously, self-levelling. At this very viscous consistency the flow is most impressive. On a real installation, it can can be made wetter, to flow faster. After doing the demo. once, no need to weigh out the quantities.

2. THERMAL SHOCK RESISTANCE AND INSULATION

Take two crucibles. Put one upside down on a clearing at least 4m diameter, with no combustible materials nearby. Place the other crucible on top of it, upright. The lower crucible is to keep the demo. one away from splashes, which could burn you or make it difficult to pick up the crucible after the reaction. The splashes also heat the outside of the crucible if it is on the ground. If you only have one crucible, substitute a brick or something.Pour thermit powder into the crucible, about half full. Make a depression in the thermit powder and place in it either about a teaspoonful of ignition powder or push in a starlighter. Over this, place about half a teaspoon of fuse powder. Light the fuse powder with a match and move up-wind of it.The fuse powder gives off a lot of smoke, and lights the ignition powder/starlighter. The ignition powder generates intense heat and ignites the thermit powder. The thermit powder splashes sparks up to 1m away. It reaches a temperature of over 2000°C. Once the sparks have stopped for at least 6 seconds, pick up the crucible in your hands. The outside will still be cold, and remain so for at least half a minute. You can now pour out some molten steel, if there is a completely dry surface available. Give the crucible to the customer to hold.

The purpose of the demonstration is;

1. To impress the hell out of the customer.
2. To show that Kerapour can withstand a thermal shock of ambient to 2000°C in seconds without cracking.
3. To show how good cellular insulation is.
4. To prove that Kerapour can withstand super hot molten metal in a breakout situation.

Kerapour demo. crucibles are prefired to 400°C.

In the event of a burn from a spark, apply Bactrazine Flammazine ointment to the burn. (It has never happened yet in about 50 demonstrations.)

The demonstration is very impressive and frequently misleads the customer into considering Kerapour for high continuous temperature applications. Most of the applications which the customer now thinks of can be satisfied by Kerapour, Hollocast castable, Keratuff/Keratuff 2 plaster, or Kerapump 1 to 5.

Now that you have the customer's attention and interest, you will find him very communicative.
