Thermal insulation materials on the market today are many types and are usually distinguished according to characteristics such as surface shape, internal structure, types of materials for initial production, density, degree when compressive deformation (hardness), thermal conductivity, flammability, etc .. In this section, we distinguish the shape materials outside.
The external shape of the insulation is divided into:
. Bales materials (blocks, mats, rolls) product usually plates, coils, tubes (rockwool insulation, ceramic cotton)
. Heat insulation materials ropes, cushions (rope insulation)
. Heat-removable porous (cotton ceramic bulk, bulk vitreous)
The most common are hard insulation sheets of 1m in length - 1m2, 0.5m width, and a thickness of about 5-10 cm, depending on the density of the material. The thickness of the material is proportional to the thermal resistance value of the material, the smaller-sized panels are usually made from lower-strength materials.
Bulk material is usually inorganic materials, organic exist in the form of powder, and cotton, such as cotton yarn bulk ceramic pottery (cotton insulation), bulk glass wool, and rock perlite insulation...
insulation construction
When dry state bulk insulation material is used to backfill the hole's walls, or openings in the machinery, or insulate the roof ceiling tiles of the floor. Inorganic materials are commonly used for insulation on industrial equipment. The addition of bulk insulation material also forms the mortar mixture used to coat the surface at a high temperature. Effective thermal insulation depends on the stability of the material layer.
Heat- often shaped bales, dimension stability and the binder and of good quality, high reliability and long life and good insulation effectively than other types of materials. These events form insulation products manufactured on the closed industrial chain, quality control, and strict monitoring process. Commonly used to insulate the smaller surface curvature, or shaped like steam pipes, chimneys, or heating pipelines, the device has a high temperature and large surface curvature abruptly as tanks, furnaces steam, and silo.
The form of insulating material workability components and shipping faster than the bulk material, thus saving cost and construction time while ensuring the quality of the insulation, if not talk is over. Materials used for insulation rolls for the small details and complex branching tubes, gauges, openings, valves, etc ...
