GWR Nano Insulation

Liquid ceramic heat insulation coverages (LCHI), including TSM Ceramic, appeared on Russian
market at the beginning of 2000 years and their application on the objects of industry and buildings
construction is swiftly broadening. What are these ultra-thin heat insulations are about?

Composition of GWR Nano Insulation
 

GWR Nano Insulation consists of membrane forming material, ceramic filler and other special
purpose additions - bioprotective, antifoam and antifreeze agents.
Styrene - acrylic latex is used in material as membrane forming component. Styrene (about 20%)
gives hardness to material, and acrylic constituent (80%) - elasticity and weather resistance.
Membrane has all properties of acrylic binder, such as weather resistance (guarantee on coverage no
less than 10 years), elasticity bend (1 mm), wonderful adhesion, with hardness about 0,4 Н/м2 at the
same time, unlike acrylates (hardness 0,2 Н/м2) and ПФ of enamels (0,1-0,3 Н/м2).
Ceramic filler. It is microspheres, filled by discharged gas, most of it is in ready made coverage
(75% volume of dried-up material). It is this component, that gives high heat insulating efficiency to
material.
Material also contains bioprotective additions (biocide, preservative, antifungal and others).
These additions prevent the processes of fermentation, prolong period of material shelf storage, and
also prevent development of fungus on a surface.
Water-based material is ecologically pure and does not contaminate the environment.


Principle of action of TSM Ceramic

Thermo physical properties of GWR Nano Insulation substantially differ from similar properties


of traditional heat insulators.
As it is known, the process of heat transfer in nature is fulfilled by plenty of physical phenomena:
• by heat conductivity of material itself;
• by convective heat exchange;
• by radiation.
Therefore resulting heat conductivity of any physical body is determined as a sum of these three
constituents.
GWR Nano Insulation is a capillary and porous body. Its interporous space is filled by ceramic
spheres that are being in discharged state. The gas, contained in microspheres, practically, does not
conduct warm. In the process of heat transfer the wall of microsphere is heated at first, then gas inside
of microsphere, then opposite wall, further, the heat is passed to the nearby microspheres with a loss
of energy in every case. Taking into account that the diameter of sphere is microscopic (~10 mkm), a
thermal stream has to do a long and winding way, although the thickness of material is only 0,5-3
mm. Thus, the rarefaction of interporous space significantly reduces the convective part of heat
transition. It is known that at zero gravity convective heat exchange is absent at all.

GWR Nano Insulation, except heat transfer by heat conductivity, is semilucent for infrared (IR)
radiation, i.e. has absorbing, radiating and dispersive properties, that fundamentally change the
structure of thermal losses from a surface coverages, that consist of convective losses due to ablution
of surface with surrounding air and radiation losses due to «relighting» of wall with terrene and
welkin. For these reasons the heat emission coefficient of GWR Nano Insulation (1,29-2,2 W/of m2 0С)
is much below the level of other building and heat insulation materials (9-23 W/of м2 0С).
GWR Nano Insulation along with other hi-tech advantages possesses values, that practically do
not meet in one material:
- heat insulation;
- waterproof;
- anticorrosive;
- soundproof.
Research of liquid ceramic heat insulation (LCH) efficiency has some difficulties. Ultrathin heatinsulation
materials has not entered in operating СНиПы and GOST, there were no methodologies of
research for similar materials, both as suitable measuring equipment.
Optical descriptions of GWR Nano Insulatare coefficients of absorption, reflection, radiation,
that substantially differ from analogical descriptions for black metals, building materials or standard
heat isolations. Therefore sensors of thermal streams that are used in practice of technical control
should be applied with special calibration, because of high reflectivity and low level of GWR Nano Insulation
 coverage blackness, that result in substantial errors while using sensors, calibration of
which was carried out with use of model blackbody emitters only for the values of radiation ability,
that are close to 0.99, and are working in the spectral range of 7-18 mkm. Taking temperature probes
of surface without introduction of special methodical amendments to the results of measuring, both as
use of special filters to optical part of pyrometer, can result in substantial errors during fixing the final
description.
At the same time, researches of GWR Nano Insulation, conducted in Moscow, Saint Petersburg,
Kyiv, Minsk, Astana, Samara, Krasnoyarsk and other cities of Russia (based on energy saving at

maintenance of programmed temperatures after putting GWR Nano Insulation of different thickness
on enclosing structures, indicated high efficiency of material. According to these researches material

thickness of 0,25 mm gives 15% of heat economy , 0,5 mm - 25%, 1 mm - 40%.
