During the use of tunnel fireproof coatings, some fireproof coatings can achieve the expected effect, while others do not achieve the expected effect during the use in buildings. Some even affect the changes of the building that was originally attached to it. So, what are the reasons that affect the performance of fireproof coatings? Let's take a look together below.

The factors that affect the expansion and foaming of fireproof coatings are inorganic fillers and pigment fillers. The effect of inorganic fillers on fireproof coatings is to affect the foaming effect of the coating. Excessive pigment has a certain inhibitory effect on swelling. Affects the height and thickness of the expansion foam. Thereby reducing the insulation effect.

The impact of TiO2 application on the fire resistance of fire-resistant coatings.

 The optimal dosage of TiO2 in tunnel fireproof coating manufacturers is 7.5%, which forms a high carbonization protective layer and greatly improves the fire resistance limit. The foam layer formed by foaming has good fire resistance, and the foam layer is dense. When the dosage of TiO2 is less than 7.5%, the refractory time will be prolonged with increasing dosage. TiO2 can greatly enhance the strength of fire-resistant coatings, without producing gas, forming a stable expanding skeleton layer, which increases the strength of the formed carbonaceous layer and enhances the fire resistance of the coating. When the TiO2 content exceeds 7.5%, the fire resistance limit will be significantly shortened with the increase of dosage. This is because excessive addition of TiO2 increases the strength of the carbonaceous protective layer, but to some extent suppresses the expansion of the coating.

The above introduction makes it clear that attapulgite, rutile TiO2, and kaolin can all affect the performance of fireproof coatings. Therefore, the use of attapulgite, rutile TiO2, and kaolin materials must be controlled during construction. Enhance the effectiveness of fire-resistant coatings.

1. Cleaning agents can remove odors. You can go to the market to purchase some high-tech deodorizing cleaning agents, which can remove harmful gases emitted from newly renovated houses, new furniture, etc.

2. The fruit deodorization method also uses tropical fruits to remove odors, which is effective, cost-effective, and simple. Using jackfruit to remove the pungent odor of newly decorated houses, the effect is also very good. Newly decorated houses often have various pungent chemical raw material smells. Put a broken jackfruit in the house. Because jackfruit is large and has strong fragrance, it can remove the odor in a few days. 

3. Fill a container such as a basin or small bucket with cold water, then add an appropriate amount of vinegar and place it in a ventilated room, and open the furniture door. This can not only evaporate moisture appropriately to protect the surface of the wall top coating, but also absorb and eliminate residual odors.

4. Natural ventilation method, open the window on the side of the wall that is not directly dried to ventilate.

According to relevant sources, these deodorizing and cleaning agents use ammonia compounds to undergo chemical reactions with harmful substances, thereby playing a role in deodorizing and cleaning. In newly renovated rooms, this deodorizing cleaner can be poured into a dish and placed separately in each room. Combined with scrubbing and deodorizing methods, it can effectively remove unpleasant odors after several consecutive days. This not only reduces the harm of cleaning agents to our bodies, but also reduces the residual toxic gases. Jiangxi Tunnel Fireproof Coating
