calcium silicate production process

How Calcium Silicate Insulation Is Made Johns Manville

The entire process is relatively low-energy, as the highest temperature reached during manufacturing is less than 400°F (204°C). The cured calcium silicate insulation material consists of more than 90% air. Tiny air spaces separated from one another by low-thermal-conductivity walls give calcium silicate its superior insulating characteristics.

US4131638A Process for the manufacture of calcium

An improved "pre-autoclaving" process for the formation of fiber-reinforced calcium silicate hydrate bodies (such as thermal insulation) is disclosed. The improvement comprises first cooling the crystal slurry from the reactor in a heat exchanger and then metering the cooled slurry through a venturi to reduce the pressure and control the flow rate.

USRE32673E Process for the production of calcium

A process and apparatus is provided for the production of calcium silicate-containing stone blanks which are useful in constructing building walls. A crude mixture, of a granulated silicate-containing material, lime, water, a cement and a foaming agent, is subjected to no more than a minimum application of external pressure and is subsequently hardened in an autoclave.

Calcium Silicate Skamol

Calcium silicate consists primarily of two elements: quicklime and microsilica, where microsilica initially was a waste product from the production of silicon metal and ferrosilicon. Microsilica became a rather costly waste product and therefore, the desire to recycle the material arose in the silicon industry.

Calcium silicate Wikipedia

Properties. Calcium silicate is a white free-flowing powder. It can be derived from naturally occurring limestone and diatomaceous earth, a siliceous sedimentary rock. [citation needed] It is one of a group of compounds that can be produced by reacting calcium oxide and silica in various ratios e.g. 3CaO·SiO 2, Ca 3 SiO 5; 2CaO·SiO 2, Ca 2 SiO 4; 3CaO·2SiO 2, Ca 3 Si 2 O 7 and CaO·SiO 2
