Although fire-resistant fabrics and fire-resistant coatings have certain fire-resistant effects in terms of function and use, there are obvious differences between them, mainly reflected in the following aspects:
1, Definition and Material
Fireproof fabric: also known as flame-retardant fabric, it is a special fabric with functions such as fire resistance, flame retardancy, thermal insulation, insulation, and sound insulation. It has a variety of materials, such as silicone rubber coated fiberglass cloth, basalt fiber fireproof cloth, acrylic cotton fiber fireproof cloth, etc. These materials have undergone special treatment, giving them excellent high-temperature resistance and flame retardancy.
Fireproof coating: It is a special type of coating that forms a protective film by brushing on the surface of an object to reduce its flammability, prevent the rapid spread of fire, improve the fire resistance of the coating, and thus protect the safety of the object. Fireproof coatings are mainly composed of fire-resistant resins, flame retardants, etc., and are divided into two types: expansion type fireproof coatings and non expansion type fireproof coatings.
2, Working principle
Fireproof cloth: mainly prevents the spread of flames through its high temperature resistance and flame retardant properties, while its insulation performance can effectively slow down the transfer of heat.
Fireproof coating: It forms a protective film to block the erosion of flames and high temperatures on the substrate. This protective film can have functions such as insulation, heat absorption, and flame retardancy, thereby preventing flames from spreading to surrounding objects. For intumescent fire-retardant coating, its surface coating will melt, bubble and bulge under flame and high temperature, forming a uniform and dense honeycomb or sponge foam insulation layer, releasing non combustible gas, further isolating oxygen and heat conduction.
3, Application field
Fireproof fabric: Due to its excellent fire and thermal insulation performance, it is widely used in various fields such as construction, automotive, aviation, military, chemical, etc. In the field of construction, fireproof cloth can be used for the manufacturing of building components such as fireproof doors and fireproof rolling shutters; In the field of automobiles, it can be used for thermal insulation protection of parts such as exhaust pipes and engines.
Fireproof coatings are mainly used in building structures, wooden furniture, floors, partitions, cables, vehicles, and other fields. In building structures, fireproof coatings can be used for steel structures, concrete structures, etc., to improve the fire resistance level of buildings; In the fields of wooden furniture, flooring, etc., fireproof coatings can prevent flames from spreading to the wood; In the fields of cables and vehicles, the application of fireproof coatings can prevent fires caused by electrical equipment.
4, Construction and Maintenance
Fireproof cloth: The construction is relatively simple, usually just cover or wrap the fireproof cloth on the object that needs protection. However, it should be noted that fireproof cloth may be worn or contaminated during use, so regular inspection and replacement are necessary.
Fireproof coating: During construction, it is necessary to apply or spray on the surface of the object, and ensure the uniformity and thickness of the coating. After construction, it is necessary to wait for the coating to dry and solidify before use. In terms of maintenance, fireproof coatings generally do not require special maintenance, but care should be taken to avoid scratching or damaging the coating.
In summary, there are significant differences between fireproof cloth and fireproof coating in terms of definition, material, working principle, application field, construction and maintenance. When choosing to use, it is necessary to choose appropriate fireproof materials based on specific application scenarios and needs.
