The thin-coated steel structure fireproof coating refers to the steel structure fireproof coating whose coating thickness is greater than 3mm, less than or equal to 7mm, has a certain decorative effect, expands and thickens at high temperature, and the fire resistance limit is within 2 ਐਚ. This kind of fireproof coating for steel structure is generally composed of a suitable water-based polymer as the base material, and then composed of a composite system of flame retardants, fire retardant additives, fire-resistant fibers, etc., and its fire prevention ਸਿਧਾਂਤ ਅਲਟਰਾ-ਪਤਲੀ ਕਿਸਮ ਦੇ ਸਮਾਨ ਹੈ. For this type of fireproof coating, the water-based polymer required to be selected must have good adhesion, durability and water resistance to the steel substrate. Its decoration is better than thick fireproof coatings, inferior to ultra-thin steel structure fireproof coatings, and the general fire resistance limit is within 2 h. Therefore, it is commonly used in steel structure fire protection projects with less than 2 h fire resistance limit, and spray construction is often used. In one period, it occupied a large proportion, but with the emergence of ultra-thin steel structure fireproof coatings, its market share was gradually replaced.

Thick steel structure fire retardant coating refers to the coating thickness is greater than 7 mm, less than or equal to 45 mm, granular surface, small density, low thermal conductivity, fire resistance limit of more than 2 h steel structure fire retardant coating. Since the composition of thick fire retardant coatings is mostly inorganic materials, its fire performance is stable and the long-term use effect is good, but the particles of its paint components are large, the appearance of the coating is uneven, affecting the overall beauty ਇਮਾਰਤ ਦਾ, ਇਸ ਲਈ ਇਹ ਜਿਆਦਾਤਰ struct ਾਂਚਾਗਤ ਛੁਪਣ ਵਾਲੀ ਇੰਜੀਨੀਅਰਿੰਗ ਲਈ ਵਰਤਿਆ ਜਾਂਦਾ ਹੈ. This kind of fire retardant coating uses the granular surface of the material in the fire, the density is small, the thermal conductivity is low or the heat absorption of the material in the coating, which delays the temperature rise of the steel and protects the steel . This kind of fireproof coating is made of suitable inorganic binder (such as water glass, silica sol, aluminum phosphate, refractory cement, etc.), Then it is mixed with inorganic lightweight adiabatic aggregate materials (such as expanded perlite, expanded vermiculite, sea bouldering, floating beads, fly ash, etc.), fire retardant additives, chemical agents and reinforcement materials (such as aluminum silicate fiber, rock wool, ceramic fiber, glass fiber, etc.) and fillers, etc., which has the advantages of low cost. Spraying is often used in construction, which is suitable for indoor and outdoor concealed steel structures with fire resistance limits of more than 2 h, high-rise all-steel structures and multi-storey factory steel structures. For example, the fire resistance limit of the columns of high-rise civil buildings, general industrial and civil buildings supporting multi-layer columns should reach 3h, and the thick fireproof coating should be used to protect them.

 

 

  • ਦੂਜਾ, ਇੱਕ ਸੁਰੱਖਿਆ ਪਰਤ ਦਾ ਗਠਨ: ਇਹ ਹੈ, ਗੈਰ-ਧਾਤਰੀ ਜਾਂ ਧਾਤ ਦੀ ਸੁਰੱਖਿਆ ਵਾਲੀ ਪਰਤ ਨੂੰ ਕੋਟਿੰਗ:

ਧਾਤ ਦੀ ਸੁਰੱਖਿਆ ਵਾਲੀ ਪਰਤ ਮੁੱਖ ਤੌਰ 'ਤੇ ਪਰਤ ਵਾਲੀ ਧਾਤ ਦੇ ਆਕਸੀਕਰਨ ਅਤੇ ਪੈਸਿਵੇਸ਼ਨ ਇਲਾਜ ਲਈ ਵਰਤੀ ਜਾਂਦੀ ਹੈ. The non-metallic protective layer is mainly the coating of paint, plastic, enamel, mineral grease and so on on the metal surface to form a protective layer. The purpose of these two protective layers is to isolate the base material from contact with seawater, instead of reacting with seawater, thus forming protection
