Color steel plate can be divided into polyurethane (PU) color steel plate, rock wool color steel plate, glass wool color steel plate, paper honeycomb sandwich plate, foam color steel plate (chemical name is polystyrene (EPS) color steel plate), etc. according to different sandwich materials.
Polystyrene (EPS) foam color steel plate, also known as foam color steel plate, is an organic material with the characteristics of heat insulation, light weight and easy installation. It has been widely used in recent years. The disadvantage is that the foam color steel plate is very easy to burn and cannot meet the national fire protection requirements.
According to relevant data, polystyrene (EPS) foam sandwich panels will soften and have droplets when exposed to high heat or open fire, which will accelerate the spread of fire; Due to the presence of cyanide and chlorine in the ingredients, toxic smoke can be emitted, causing poisoning and suffocation of personnel. Foam color steel plate is easy to cause heavy property losses and casualties due to its rapid spread after fire and high toxicity of combustion products.
Polyurethane color steel plate is composed of upper and lower layer color steel plates and foam polyurethane in the middle. It is one of the widely used building materials in the current construction industry, and has good insulation, heat insulation, and sound insulation effects. Many people often mistake foam color steel plate for polyurethane sandwich plate.
Rock wool color steel plate is a new type of fire-resistant plate in the color steel plate series, which is made of natural rocks, blast furnace iron ore slag, etc., melted into silk at high temperature, and then solidified into shape. Rock wool color steel plate meets the secondary fire protection requirements of clean workshops and is an ideal structural decorative plate for indoor ceiling and activity room construction. It has a fire resistance of 600 ℃ and a fire resistance rating of Class A.
The domestic rock wool product market is plagued by a large number of mixed pearls and inferior products. A large number of slag wool with substandard weather resistance, acidity coefficient, tensile strength, slag ball content, hydrophobicity, moisture absorption rate, bulk density, etc., impersonating qualified rock wool, seriously disrupting the market, and reducing the service life and performance quality of rock wool and related application products.
The glass wool of the glass wool colored steel plate is an artificial inorganic fiber with a diameter of less than 6 microns, which is made by melting minerals such as lime and quartz powder in a furnace, centrifuging or spraying at high speed, and then forming various products using molding equipment. The main glass wool colored steel plates include three series: glass wool board, glass wool pipe, and glass wool felt. This product has a series of advantages such as low thermal conductivity, small bulk density, stable chemical properties, non aging, and non flammability. It has good construction performance, is easy to cut and process, has no on-site losses, does not produce harmful gases, and its long-term performance remains unchanged.
