Metallurgy and refractories


We offer mutually beneficial partnership in the supply of «NDP» component of our own production for the lining, as well as for the production of thermal insulation mixtures based on highly porous thin diatomite for this flame-resistant, durable (6-7 on the Mohs scale) and light (200-400 kg / m3) material based on amorphous silicon!

Thermal insulation products with diatomaceous earth used in the construction of furnaces in ferrous and non-ferrous metallurgy, chemical plants.


Formulations

Manufacturing method of molding and calcination of diatomite with burnable additives.
(such as sawdust for the formation of additional voids)

Production of thermal insulating products of asbestos amorphous blend (15%) and diatomaceous earth (85%)

For cords, use a dry milled
clay
in the ratio: diatomite 90-95%, 5-10% dry milled clay

The resulting mass is stirred well, shuts water and molded for subsequent drying and firing

Added sawdust during firing burn out, leaving a cavity

From the aqueous mixture of:

65%
diatomite

20%
of hydrated lime

15%
asbestos

produce calcium silicate heat-insulating material
of high strength and flame resistance
,
which can be given various forms steaming them
in an autoclave.



Advantages

porosity up to 88%

Specific surface
to 30,000 cm2 / g.

Excellent mixed due to
the fine dispersion of micron size.

Bulk density
200 kg / m3

The strength
of 6-7 Mohs units
