MAT 125

 

  1. Short Description: Insulating gunning material, to be used as insulating lining. Insulating gunning materials are categorized in different categories according to their density.

 

  1. Packaging-Storage
  • These refractory materials are packed in special paper sacks, of about 20 Kgr, in wooden pallets.
  • Shrink foil wrapping protects the refractory materials against moisture.
  • These refractory materials should be stored in dry place and cool warehouse (shelf life is indicative to the Technical Data Sheets).
  •  Pallet stacking is admissible and the max loaded pallets must not exceed 2 pallets. If the shelf life has been exceeded, our Technical Service Department should be contacted before use.
  • “First in – First out” management of stored materials is advisable.
  • The material has to be stored above freezing temperature.
  • Due to high humidity and strong solar radiation in tropical countries, storage in a dry, covered place is recommended.
  • The shrink wrapping should be removed only prior to mixing.

 

  1. Tools and Machnery/ Preparation before casting
  • Gunning machines, accessories and surrounds must be clean and free from foreign material.
  • The area for gunning must be clean.

 

 

  1. Water required (lit/100 kg) (EN 1402-4): 40-50

 

 

  1. Material Required at kg/m3 : 1000

 

 

  1. Installation-Casting
  • Insulating gunning materials are fed to the hopper of the gunning machine.
  • The compressed air pressure and the added water must be carefully adjusted.
  • The mixing of the gunned material with the potable water takes place at the gunning nozzle, which is equipped with a water control valve.
  • Good communication between the nozzle and gunning machine operators is required at all times to ensure the installation is correct.
  • The control of the added water is critical for the stickiness, the rebound and the generated dust.
  • If the gunning mix sticks to the wall with the smallest rebound, the amount of water used is correct. If the gunning mix is too wet, it will slide down the wall.
  • The rebound contains set cement and can not be reused anymore.
  • The processing quality depends on striking angle, gunning pressure, gunning mix thickness etc.

 

 

  1. Anchoring and Supporting
  • Depending on the dimensions and the location of the refractory lining it is necessary to use anchors; for temperatures up to 1200°C, steel anchors can be used and over 1200°C, ceramic anchors must be used.
  • Refractory grade anchors can be selected depending on the highest temperature, the corrosion environment and the specific project conditions.
  • Steel anchors can be selected depending on the highest temperature. They must be painted with bitumen or insulated with tape to avoid cracking.
  • Steel anchors have to be protected with 30 mm of refractory material against the hot face.

 

 

  1. Drying and Heating up
  • Cement based gunning materials must be dried before starting pre-heat.
  • All gunning materials have to be compatible with the pre-heat schedule for the whole kiln.
  • The drying and pre-heat temperature is available on request from our Technical Service Department.

 

 

  1. Winter precautions
  • If the temperature at the point of installation is below 5°C, pre-heating is strongly recommended.
  • Temperature during setting should be above freezing point.
  • In case of, out of temperature limit conditions, please contact our Technical Service Department.

Important Note: The above instructions are suitable for the most of uses. The final User must follow carefully the instructions of Designer of each specific project.

  • Steel anchors have to be protected with 30 mm of refractory material against the hot face.

 

 

  1. Drying and Heating up
  • Cement based gunning materials must be dried before starting pre-heat.
  • All gunning materials have to be compatible with the pre-heat schedule for the whole kiln.
  • The drying and pre-heat temperature is available on request from our Technical Service Department.

 

 

  1. Winter precautions
  • If the temperature at the point of installation is below 5°C, pre-heating is strongly recommended.
  • Temperature during setting should be above freezing point.
  • In case of, out of temperature limit conditions, please contact our Technical Service Department.

 

Important Note: The above instructions are suitable for the most of uses. The final User must follow carefully the instructions of Designer of each specific project.

Thank you for choosing our products.

 

The following instructions will help you make the most out of our quality.

 

MAT 124 G

  1. Short Description: Insulating gunning material, to be used as insulating lining. Insulating gunning materials are categorized in different categories according to their density.

 

  1. Packaging-Storage
  • These refractory materials are packed in special paper sacks, of about 20 Kgr, in wooden pallets.
  • Shrink foil wrapping protects the refractory materials against moisture.
  • These refractory materials should be stored in dry place and cool warehouse (shelf life is indicative to the Technical Data Sheets).
  •  Pallet stacking is admissible and the max loaded pallets must not exceed 2 pallets. If the shelf life has been exceeded, our Technical Service Department should be contacted before use.
  • “First in – First out” management of stored materials is advisable.
  • The material has to be stored above freezing temperature.
  • Due to high humidity and strong solar radiation in tropical countries, storage in a dry, covered place is recommended.
  • The shrink wrapping should be removed only prior to mixing.

 

  1. Tools and Machnery/ Preparation before casting
  • Gunning machines, accessories and surrounds must be clean and free from foreign material.
  • The area for gunning must be clean.

 

 

  1. Water required: mixing at nozzle

 

 

  1. Material Required at kg/m3 : 1250

 

 

  1. Installation-Casting
  • Insulating gunning materials are fed to the hopper of the gunning machine.
  • The compressed air pressure and the added water must be carefully adjusted.
  • The mixing of the gunned material with the potable water takes place at the gunning nozzle, which is equipped with a water control valve.
  • Good communication between the nozzle and gunning machine operators is required at all times to ensure the installation is correct.
  • The control of the added water is critical for the stickiness, the rebound and the generated dust.
  • If the gunning mix sticks to the wall with the smallest rebound, the amount of water used is correct. If the gunning mix is too wet, it will slide down the wall.
  • The rebound contains set cement and can not be reused anymore.
  • The processing quality depends on striking angle, gunning pressure, gunning mix thickness etc.

 

 

  1. Anchoring and Supporting
  • Depending on the dimensions and the location of the refractory lining it is necessary to use anchors; for temperatures up to 1200°C, steel anchors can be used and over 1200°C, ceramic anchors must be used.
  • Refractory grade anchors can be selected depending on the highest temperature, the corrosion environment and the specific project conditions.
  • Steel anchors can be selected depending on the highest temperature. They must be painted with bitumen or insulated with tape to avoid cracking.
  • Steel anchors have to be protected with 30 mm of refractory material against the hot face.
