Product description：
High temperature furnace pump repair material is a water-based high temperature insulation heat pump injection material, containing special engineering ceramic fiber, inorganic filler, inorganic binder, and trace organic polymer and other components, so that the product has a high temperature adhesive and curing joint filling. The pump filler is a pre-made colloidal material, which can be applied by hand-held caulking gun, pumping equipment, spraying equipment or ash shovel. The material forms a hard lump after drying, and has good insulation, strength and vibration resistance. This pump is used for caulking and sealing of high temperature equipment. It can also be used for hot repair or cold repair of any aged backing insulation material in kilns, ovens, furnaces, boilers, and other high temperature equipment. It can also be used for hot surface repair of cracks caused by shrinkage of existing refractories, surface repair of refractories, and finish spraying for enhanced thermal insulation.
Product characteristics：
High refractoriness: good thermal shock resistance, up to 1600℃.
Corrosion resistance: Excellent resistance to chemical attack, excellent chemical stability.
High strength: moderate density after sintering, high bonding strength.
Good construction: good construction performance, ready to use.
Anti-cracking: dry shrinkage, high temperature for a long time without cracks.
Typical applications:
Thermal repair or cold repair of refractory backing insulation material;
Thermal or cold repair of boiler insulation layer, side wall and furnace top;
Thermal repair and cold repair of cracks in brick kiln roof and brick wall;
Thermal or cold repair of coke oven side walls and seals;
High temperature caulk for electronics and lithium battery packs.
Construction guide：
1. Construction of plastic barrel pumping repair material
The prepared plastic barrel can be loaded with a glue gun, and the use method is the same as that of ordinary glass glue; Apply glue to the surface of the cleaned object, and then smooth it with a spatula.
2. Construction of barrel-filled pump repair material
Barreled products can be manually constructed in the form of trowels, or pumped equipment can be used for construction; Small and medium-sized repair, it is recommended to use stainless steel caulking gun, choose different styles of gun head according to the site construction location needs, you can also make your own extension pipe according to the site needs; For large repairs, it is recommended to use a hop-type pneumatic pumping unit, which requires compressed air to operate (typically a maximum pressure of 5-7psi). The weight of the pumpable unit is approximately 20kg; You can contact the service personnel to recommend construction equipment.
3. Curing conditions
Pump repair material can be dried at room temperature, but it takes a long time; It is better to use it directly with the heating of the furnace or to use it after the strong exhaust heating and drying at 100℃. Some fog will appear at the temperature raised by the first ignition, requiring ventilation to allow steam to escape.
