ASTM C533 TypeⅠ product
Water-Repellent, Anti-Corrosive Calcium Silicate Thermal Insulation Material
|
|
|
DAIPALITE-EiA
is a calcium silicate thermal
insulation material which is pre-formed
for pipe and block section and used for
facilities. DAIPALITE-EiA is inorganic,
asbestos free and noncombustible.
DAIPALITE-EiA 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-EiA
DAIPALITE-EiA is surface-treated with a special corrosion inhibitor containing soluble components (Na+, SiO32-). When the components are dissolved in water, the pH of the solution is more than 10, and a passive film is formed on the pipe surface, preventing iron corrosion.
|
- DAIPALITE-EiA is a water-repellent material, not water-proof. The functions of water-repellent and corrosion inhibition of DAIPALITE-EiA 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-EiA is under 250℃ of the
surface temperature of the facilities as the water-repellent function will be
lost over it.
