Cellular glass blocks for heat insulation
Characteristics of the proposed material
The product key characteristics are the following:
Sizes
from 0.1 m up to 1.2 m in length (width)
and from 0.02 m up to 0.2 m in thickness
(the samples were obtained and the experience
of preparation the mentioned sizes is exist)
Shape
accuracy is ensured by the technology and
the resulted blocks shape is not need
in the additional sawing and the resulted
product is characterized with the homogeneity
of the surface
Density
from 250 kg/m3 up to 600 kg/m3
Heat conduction coefficient
from 0.067 W/(m•K) up to 0.12 W/(m•K)
The compressive strength
from 1.5 MPa up to 7.5 MPa
Color
any, according the customer's request
The product differences from analogues
The foamed glass plates are the nearest analogue of the proposed product. The technical characteristics and another information about foamed glass are available at the manufacturers' websites: Pittsburgh Corning www.foamglas.com and STES-Vladimir www.a-stess.com
- Possibility of colored material manufacture (not just black, as foamed glass) and the material applying as a facing one
- Material accurately specified size directly in the furnace manufacture is possible that eliminates the sawing of finished products and leads for the smooth surface
- Increased strength of the material allows its using as self-supporting
- The resulted product manufacture of exactly sizes and of relief and bulk share without additional machining, allows to release the shell, bas-reliefs and sculptures
The proposed technology differences of from analogues
- Various types of raw materials such as glass cullet (including off-grade) and natural silicate (diatomite, tripoli, flask, zeolites) are possible
- The metal forms absence during heat treatment significantly reduces the energy intensity and excludes the defect product
- Available and maintainable equipment is applied
- High cost and hard-to-reach components are absence in raw materials
- The relatively low cost of the products obtained in the range from 100 up to 160 €/m3 (it depends on raw materials type, manufacture productivity and type of products)
- The author's experience in installation and starting the manufacture of similar materials in combination with one of the highest h-index among the experts in this field
