Product Description

A free-flowing white powder is calcium silicate. A siliceous sedimentary rock made of naturally occurring limestone and diatomaceous earth can be obtained. It belongs to a category of substances which can be generated through the reaction of calcium oxide and silica in different proportions, for example. Alite is composed of 3CaO·SiO2 (Ca3SiO5), while (Ca2SiO4) is made up of 2CaO·SiO2 and (Ca3SiO7) consists of 3CaO·2SiO2. Additionally, wollastonite (CaSiO3) is comprised of CaO·SiO2. Its physical water absorption is high while its bulk density is low.

The primary components of calcium silicate pipe are SiO2, CaO, and reinforcing fiber. The stirring, heating, gelling, forming, pipe hardening and drying process is utilized to make the products. This material is suitable for use in construction due to its light bulk weight, low thermal conductivity, and high bending and compressive strength. Thermal insulation for building partition walls, curtain walls, roofs, and building envelopes, as well as petroleum and electric power.

1. Obvious cooling : As a backing insulation materials,they have a very marked effect of energy consevation,as a result of less accumulation of heat and bigger heat protection.
2. Good durability: After long used,the boards do not shrink,out of shape and turning powder out,insulation performance does not decline .
3. High rate strength: The rate strength of calcium silicate tube is the highest in the thermo inorganic material.During the design,it can lighten the all-up weight of the kiln and stove greatly.
4. Easy construction: Using common woodworking tools can be cut to any necessary form,and can be glued and formed with other materials easily.
5. Environmental protection: No corrosives and toxicity,there are not exhaust gas and peculiar smell under the high temperature,will not cause the injury and pollution to the human body and environment.It’s belong to the products of environment protection.
