NTRODUCTION
Energy conservation via lowering building energy
consumption is one of the most crucial and urgent
problems in the current construction sector. One
of the priority is, in particular, the effective use of
thermal energy in structures, heat pipelines,
energy networks, and other sectors. This is
because there aren't enough energy supplies
available, it's expensive, and producing it has a
bad effect on the environment.

The Fergana Polytechnic Institute's Youth Center
for Innovative Technologies is conducting
research to enhance the procedure for calculating
the thermal conductivity of heat-insulating
coatings.
This paint is used for internal heat retention and
protection, heating and engineering networks,
process pipes, thermal energy and capacity
equipment, waterproofing, corrosion protection,
and construction of facades of residential and
commercial structures. made with building in
mind.
Acrylic binders, hollow microspheres in the form
of entire fillers, and other materials are used to
create the paint.
Thermal insulators that contain hollow
microspheres as part of their composition
operate very differently from "classic" heaters in
terms of how they work. The material has a
considerable energy-saving effect even at a
thickness of 1 mm because of its special qualities.
Waterproofing also contains anti-corrosion
features in addition to its heat-insulating
qualities, which include compounds that are
water-resistant (impermeable). The coating is
made waterproof, flexible, and resistant to UV
rays, temperature changes, moisture, and
environmental conditions thanks to the
components.
As soon as the coating is applied, air reacts with it
to create a long-lasting polymer covering that has
great thermal insulation qualities that lessen heat
loss. One coating's drying layer creates a film with
a thickness of 0.1 to 0.5 mm.
At both low and high temperatures, our paint has
a high viscosity and is flexible. Throughout its
lengthy service life (up to 15 years), the paint
does not split or undergo chemical changes, nor
does it contain any base material remnants.

Picture 1. Results from the experiment
The paint has excellent adhesion (glass adheres to
concrete, brick, cement-sand plaster, metal,
plastic, wood, and other materials), inhibits
corrosion and condensation on chilly surfaces,
and is mechanically and atmospherically impact
resistant without the need for extra protection.
Ceramic or silicone balls are vacuumed inside.
They are inorganic pigments, acrylic polymers,
and suspended components in liquid synthetic
rubber. After drying, it takes on the appearance of
a light gray suspension and creates an elastic, thin
coating. A special material with flexibility,
lightness, elasticity, and the capacity to properly
attach to surfaces of any shape and practically any
chemical composition has been made possible by
the combination of such components.
The paint has the following advantages:
→ Easy to apply (can be done by spraying wi
th a
brush, roller and compressor);
→ Small size, compactness;
→ Environmentally friendly;
→ Does not contain harmful substances;
→ Good resistance to both alkalis and acids;
→ Fire resistant;
Areas of application
→ Residential and industrial buildings (ex
ternal
and internal insulation);
→ Easy
-to-install structures;
→ Metal structures (garages, containers,);
→ Heating mains, pipes, ventilation ducts;
→ Shut
-off valves (valves and valves);
→ Industrial containers;

Temperature and humidity resistance as well as
resistance to UV radiation are two additional
types of resistance to liquid insulation. Liquid
thermal insulation can be utilized both indoors
and outdoors, in childcare facilities, public dining
establishments, etc., with no functional
limitations due to the composition's usage of
solely ecologically benign components.
Even in challenging situations, simple to apply.
You can apply liquid thermal insulation in a
number of methods to the surface of your choice.
Simply select the option that best matches your
needs. There are many tools you can use,
including brushes and rollers.
Concrete surfaces should have dust, mold, and oil
removed using a brush; metal surfaces should
also be cleaned and degreased. It is advised to use
a phosphating agent to cure any rust stains on the
metal. The wood needs to be primed with primer
and biocides before the insulation is applied.
→ If you are reworking a brick surface, you must
first prime it and then plaster it.
Metal, concrete, brick, wood, plastic, and many
other surfaces are coated with thermal insulation.
Pre-cleaning, priming, diluting with water of the
same composition (not more than 5%), or using
the surface as a primer can be utilized for any
acrylic paint or liquid glass mixture.
Pushing the mixture on a wet, icy surface is not
advised. There are multiple layers of mixture set
down. Depending on the objectives, the tasks will
define how many layers are needed. With drying
breaks, the layers can be applied more than once.
Depending on the heat carrier temperature and
the desired surface temperature, the final coating
thickness is chosen.
Any geometric shape's surface can simply have
the coating applied to it using a brush, spatula,
roller, or sprayer. No hazardous substances are
released into the atmosphere by the coating.
When working indoors, it is advised to use a
standard respirator; however, when working
outside or in a ventilated space, no respirator is
necessary. 750

1000 g/m2 is the typical
consumption for producing a dry coating layer
with a thickness of 1 mm.
The inspection took place outside. Three layers
make up the coating. 3 mm was the final
thickness. The total amount of coating used was
0.9 liters.
