YuFeng lime kiln insulation materials science environmental

Article source:

In building materials, metallurgy, chemical industry, environmental protection and many other manufacturing industries, the widespread use of rotary equipment device for solids, powders, gases and other materials for mechanical, physical or chemical treatment, such devices device known as the rotary kiln, rotary kiln general kiln shell divided in horizontal and rotary movement can be called the kiln, also known as rotary kiln. Another kiln shell is called the vertical position without rotating kiln. Rotary kiln shell is the main equipment, rotary kiln shell which is (kiln) the subject of the kiln shell plate thickness of about 40mm, kiln shell temperature to reach 1,000 degrees Celsius, the high temperature should reach 1600 ℃, so the kiln shell insulation to prevent heat loss has become the key to the rotary kiln. The traditional kiln shell for better insulation, interior masonry with a layer of about 200mm silicon carbide refractory bricks or tiles, this kiln shell weight ratio, kiln shell in operation, because of the relationship between temperature and load-bearing kiln shell will There are elliptical shaped deformation, which would put pressure on the brick kiln, kiln brick insulation material impact on life. Henan YuFeng Heavy kiln insulation materials, high temperature insulation coating, paint is water-based inorganic coating, using high temperature solution and choose a selection of nano-ceramic hollow microspheres, hollow beads, and other inorganic raw materials from finishing, resistance temperature in the range of -80-1800 ℃, the thermal conductivity is only 0.03W/mK, the proportion of small, light weight, can greatly reduce the weight of the object brushing. Temperature insulation and shielding coating can effectively suppress the infrared radiant heat and the heat conduction heat, heat insulation efficiency of about 90% inhibition, can inhibit the body temperature thermal radiation heat conduction loss, internal heat of the kiln can be to maintain 70% is not lost, another fire retardant coatings, wear pressure, insulation against wear, acid, light weight, easy construction, long service life.
