Anticorrosive coatings can be used in corrosive environments. Specifically, for example, in the construction of cross-sea bridges, metals on docks exposed to harsh conditions such as seawater are coated with anticorrosive coatings, which can extend the lifespan of the metals by more than 10 years. The harsh environments we are referring to are also chemical atmospheres or marine environments.

Thick films adhere to stringent standards. Typically, the standard for thick films of anticorrosion materials is around 100m or 150m, while the anticorrosion layer should exceed 300m. In this standard, its anticorrosion effect is deemed effective.

 Anticorrosive coatings are efficient and convenient. When the operating temperature is not higher than 20 degrees Celsius and the humidity is similar, their linear drying speed is fast. Painting that takes one or two days can often be applied to other projects, such as treatment or cutting. Some anticorrosive coatings can also be combined with other industrial coatings to enhance construction efficiency.

The construction site should have adequate brightness or lighting conditions. However, to avoid direct sunlight, construction under the scorching sun is not ideal and can easily lead to film defects. The atmospheric temperature and humidity have a significant impact on the application and drying performance of coatings. The application requirements for fire-resistant coatings should clearly specify the limits of air temperature and humidity during the application process. Generally speaking, when the temperature is below 5°C and the relative humidity is above 85%, the application effect is not ideal. Various coatings have their specific application temperature and humidity requirements, which should be strictly adhered to during application. Construction in rainy weather often results in poor performance. For example, the ultra-thin intumescent steel structure fire-resistant coating made of amino acid and epoxy resin stipulates that it is not suitable for application when the air humidity exceeds 90%; it cannot be used outdoors; and it is not suitable for application on steel component surfaces or fire-resistant coatings when there is dew on the surface. The applied coating should not be exposed to rain before it is fully cured, and it should not be affected by fog or surface condensation. The applied coating should not be hollow, etc.

Dust in the air has a serious impact on the coating effect. Dust prevention measures must be taken. Different coatings require different dust prevention standards. Ventilation effects not only affect the quality of the coating, but also the safety and health of the building. When the adhesion force is greater than 3, the application of outdoor steel structure fireproof coatings should be avoided. There are personnel health protection measures in place. Construction should be carried out in a well-ventilated environment. Fire is strictly prohibited during construction. In addition, the solid content of mountain rain fireproof coatings is relatively high. Some fireproof coatings, if stored for a long time, are prone to precipitation. They should be fully stirred before use. Two-component packaged flame retardant coatings should be distributed according to the proportion specified in the product specifications, fully stirred, and allowed to react fully after the specified parking time. Then they can be used. Before construction, the viscosity of the fireproof coating should be adjusted. If the fireproof coating is too thick, an appropriate amount of diluent can be added to the coating for dilution. To adjust the construction viscosity and avoid flowing and descending during the construction process, the viscosity of the coating during spraying or impregnation is often lower than that during brushing.

The physical and chemical properties and weather resistance of Youlinsheng Fire-Retardant Coating Manufacturer are superior to those of water-based flame-retardant coatings. The decorative effect of the coating is good, and the adhesion between the coating and the substrate is high. Two issues should be considered: first, the matching of the binder with the fire-retardant system; second, the room temperature self-drying bending resistance of the coating and its bonding performance with cables. It is worth noting that economical cable fire-retardant coatings are tender and have a certain degree of toxicity. They are harmful to production personnel, construction workers, and the surrounding ecological environment. The hidden fire hazards in buildings are also considerable. Therefore, fire safety must be emphasized during production, transportation, and construction processes. Appropriate safety measures must be taken to protect people's health, especially in confined spaces such as cable wells, cable trenches, cable tunnels, or poorly ventilated areas.

Compared to fire-resistant coatings, water-based intumescent flame-retardant coatings have the following advantages: (1) They overcome the disadvantages of solvent-based fire-resistant coatings, such as high price, high toxicity, unsafe transportation, and improper storage and use. Water-based coatings have the advantages of simple production process, wide raw material sources, and low cost. Generally speaking, water-based coatings do not contain halogens and other toxic components. They eliminate the toxicity issues caused by halogens in fire-resistant coatings and reduce the toxic damage to firefighters when entering a fire scene. (4) Water-based coatings have good decorative properties and can be mixed into various colors, exhibiting the characteristics of decorative coatings. In fact, their usability is superior to that of solvent-based coatings. Currently, the fire-resistant performance of water-based cable fire-resistant coatings can meet the requirements. The problem to be solved is to improve their physical and chemical properties, especially the bending resistance. Jiangxi Youlinsheng Fire-resistant Coating Manufacturer
