Heat transfer

1. Definition of THERMAL INSULATION
1
: the process of insulating against transmission of
heat trying to reduce it as possible
2
: material of relatively low heat conductivity used to
shield a volume against loss or entrance of heat by
radiation, convection, or conduction
3
A material providing high resistance to heat flow;
usually made of mineral wool, cork, asbestos, foam
glass, fabricated in the form of blankets, blocks, boa
rds, granular fill, and loose fill.

2. Some Types of Insulation Materials

3. How To Select The Insulation Material

4. AL single bubble
• Heat insulation made of two external pure
aluminum foil layers covering a single core
layer of polyethylene bubble air film.
• FOB Price:
• US $0.7 - 1.5 / Square Mete

13. Liquid Ceramic Heat Insulation

14. Video Indications
• Liquid ceramic heat insulating consists of high-
quality binder, specially developed
formulation of catalytic and fixing agents,
superfine ceramic microspheres with rarefied
air. The main composition of the material is
supplemented by special additives that
prevent development of corrosion on metal
surface and growth of fungus on concrete
surfaces in high humidity.

15. Some Uses Of Liquid Ceramic
• Liquid ceramic heat insulating is high-
performance material for heat insulation of
building facades, roofs, internal walls,
concrete floors, hot and cold water pipelines,
steam pipelines, air ducts for conditioning
systems, cooling systems, various tanks,
vessels, trailers, refrigerators, etc.
