    Fire retardant coating is a special coating used on the surface of combustible substrates, which can reduce the flammability of the surface of the coated material, prevent the rapid spread of fire, and improve the fire resistance limit of the coated material
    .


    It can effectively prevent the spread of fire and protect the safety of life and property
    .
    There are two types of fire retardant coatings, one is intumescent fire retardant coating, and the other is non-expandable fire retardant

    .


    The following describes the respective characteristics of fire retardant coatings
    .

    NO.
    1 Features of fireproof coating

    As when you were young.


    Intumescent fire retardant coating is based on high molecular polymer, adding foaming agent, dehydration to carbon catalyst, carbonizing agent and other fire retardant components.
    The surface coating will melt, foam and bulge under flame and high temperature.
    A uniform and dense honeycomb or sponge-like carbon foam insulation layer is formed, and non-combustible gas is released

    .


    The thickness of this expanded sponge-like thermal insulation layer is often dozens or even hundreds of times the thickness of the original coating, which can well isolate the conduction of oxygen and heat, and the coating is generally thin, which is conducive to meeting decorative requirements
    .


    Non-intumescent fire retardant coating formulated with the flame-retardant resin, a flame retardant, fire filler
    .


    Inorganic salts can be used to make adhesives, with inorganic salts such as mica and borides, or halogen-containing thermoplastic resins can be mixed with halides and antimony white powder
    .


    This kind of paint has its own flame retardancy or non-combustibility to achieve the purpose of flame retardancy.
    The protective layer formed during combustion is relatively thin, the heat insulation is poor, and it can only resist instantaneous high temperature and flame, and the coating is thicker

    .


    From all aspects, intumescent fireproof coatings are more widely used, and their fireproof effect is good.
    It is the development trend of the fireproof coating industry and is also advocated by the country

    .


    Relatively speaking, we need to pay attention to what aspects of the application of fire-retardant coatings
    .


    With the rapid development of the construction industry, the requirements for decoration and fire protection are also getting higher and higher, and the demand for fire retardant coatings is also very huge
    .


    NO.
    2 Application field of fireproof coating

    As when you were young.


    1.
    The matrix material for improving the flame spread characteristics, including, for example and wood and other combustible materials as lining, insert, mat materials, etc.
    , separated

    .


    2.
    It is used to control the flame spread characteristics of non-flammable matrix materials and other reasons that need protection, such as ensuring the decoration, color stability, physical and mechanical properties stability and durability when used at room temperature

    .


    3.
    Used to improve the fire resistance of matrix materials and other materials, such as load-bearing and non-load-bearing structural parts, including steel structural parts, cast iron parts, structural parts on ships and offshore buildings, such as walls, walls, frames, partitions and other floor fire resistance, aluminum structural parts, metallic and nonmetallic cables or the like

    .


    4.
    It is used to reduce, prevent or prevent flames from damaging gas storage equipment (such as gas pipelines, storage tanks or storage tanks, etc.
    )

    .


    NO.
    3 Identify the authenticity of fireproof coatings

    As when you were young.


    Teach you a few tricks to uncover the "veil" of fire retardant coatings on the market that are both good and bad
    .


    1.
    The appearance of fire-retardant paint is very similar to that of ordinary paint.
    It is difficult to distinguish from the appearance, and it is also difficult to check the quality of fire-retardant paint on site

    .


    Consumers should pay attention to distinguish between fire-retardant coatings and ordinary coatings when choosing, so as to prevent enterprises from shoddy and failing to achieve the effect of fire protection, so as to prevent potential safety hazards
    .


    2.
    Don't be greedy for cheap when buying paint, be sure to choose well-known brand products

    .


    There are many “fire-resistant paints” on the market.
    Consumers must shop around when buying.
    Don’t be superstitious about the word “green” on the paint packaging.
    They must carefully read the product quality inspection report; observe the joints of the iron barrels.
    There is no rust or leakage; pay attention to whether the express signs on the iron bucket are complete to prevent buying counterfeit "fire-resistant paint"

    .


    3.
    When purchasing fire-resistant coatings, you can also check online whether the product has a qualified inspection report issued by the national fire quality inspection center

    .


    At present, fire-resistant paint implements a fire-fighting product type approval system, and the fire-resistant paints sold on the market should have a national fire product type approval certificate and a type inspection pass report
    .


     4.
    When the qualified fireproof coating is burned by a blowtorch or other strong fire, it will foam and expand in a large amount, and the surface will gather and bulge, and it will not burn out within a few minutes

    .


    Counterfeit and inferior fireproof coatings are basically non-foaming, and a large amount of slag will be scattered, and the wood substrate will also be burned and damaged quickly
    .


    5.
    According to national standards, in addition to meeting the requirements of fire resistance, the combustion performance of fire-resistant paint is divided into first and second levels

    .


    Under the specified experimental conditions, the flame-resistant time of the first-class fire-resistant paint is not less than 20 minutes, and the heat-resistant time of the second-class fire-resistant paint is not less than 10 minutes
    .
