When selecting fire-resistant coatings for construction, it is necessary to consider comprehensively in order to establish their rationality. Although the thicker the coating, the better the fire resistance, it is necessary to arrange the coating thickness reasonably from the perspectives of cost and building aesthetics.

The purpose of applying tunnel fireproof coating is to isolate the steel structure from fire, thereby enhancing the structure's fire resistance and protecting building safety. So when we apply fireproof coating, the thicker the coating, the stronger the fireproof ability? This is not comprehensive

Generally speaking, for non expanding fireproof coatings, it is their inherent flame retardancy and non flammability that hinder flame propagation. Therefore, the thicker the coating, the thicker the glaze formed at high temperatures, and its insulation effect is also improved.

Experts point out that for expansion type tunnel fireproof coatings, thick coatings can cause expansion and foaming when exposed to fire. The thicker the foam layer that isolates oxygen and insulation, the better the fire resistance performance. Therefore, when treating fireproof coatings, the thicker the coating, the better.

In addition, the thickness of fireproof coating also needs to be judged based on the material. For example, using high-quality fireproof coating materials has much better fire resistance than inferior products, so it needs to be carefully considered.

Fireproof coating has decorative functions similar to ordinary coatings, but it also has characteristics such as rust prevention, anti-corrosion, salt spray resistance, and acid alkali resistance. It also has a name, which is flame retardant coating, so why is it still a fire-resistant material? That's all because, in addition to possessing the above characteristics, it is inherently non flammable, so when a fire occurs, it can have a certain flame retardant effect, providing people with sufficient time for firefighting work. By now, I believe everyone knows why it is called fireproof coating.

In the early 1970s and between, our country had some fire-resistant coatings, one was inorganic fire-resistant coatings with water glass as the binder, and the other was fire-resistant products called chlorinated rubber fire-resistant paint, but the effect was not particularly good. So it wasn't until the late 1970s that research on fire-resistant coatings in our country began. Afterwards, our country made rapid progress in the research and development of organic expansion fireproof coatings, and also developed high-performance fireproof coating products.

As of now, the development of fireproof coatings in our country has formed an independent and mature systematic production and research and development chain. With the rapid development of industry nowadays, many buildings require specialized fireproof coatings for decoration, which can avoid the threat to people's safety after a fire occurs in areas with high pedestrian flow. For example, the country has regulations that require coatings used in many public buildings such as schools, cinemas, hospitals, etc. to have fire-resistant and flame-retardant functions.
