DAIPALITE-Ei is a calcium silicate thermal insulation
material which is pre-formed for pipe and block section and used for facilities. DAIPALITE-Ei is inorganic, asbestos free and noncombustible.

DAIPALITE-Ei provides both water-repellent function and corrosion inhibition effect and is supplied to various industrial fields, such as refinery plants, power plants, petrochemical plants and others.

Special Effects of DAIPALITE-Ei

 DAIPALITE-Ei is attached a special liquid which contains soluble ingredients (Na+ , SiO32-) . When the ingredients dissolved in water, it cause the water pH to be 10.6 (surface part) and forms passive film. The passive film is slightly soluble in alkalinity environment and inhibits corrosion of iron.

Water-repellent performance

Materials were watered for 60 minutes
to measure water repellencies and
absorbencies.
The result is shown in the following figure.

5

Water absorbency(%) = (M2-M1)/(V×ρ)×100

M1: Weight of test piece before watering
M2: Weight of test piece after watering
V: Volume of test piece

ρ: Specific gravity of water (ρ=1)

  • DAIPALITE-Ei is a water-repellent material, not water-proof. The functions of water-repellent and corrosion inhibition of DAIPALITE-Ei will be effective with correct installation and keeping in good condition. It is not always a guarantee of your facilities and incorrect use may result in accidents.
  • The recommended temperature in use DAIPALITE-Ei is under 250℃ of the surface temperature of the facilities as the water-repellent function will be lost over it.
