After lattice titanium infiltration to prepare nano zinc oxide containing sharp titanium, and then its special surface treatment, so that its alkalinity is weakened, easy to disperse in water-based and oil-based systems, long-term placement without delamination and precipitation. It has special effects such as anti-UV, photocatalytic and anti-mildew. The product is non-toxic and harmless, and is a new photocatalytic product of choice for nano zinc oxide.
Tunnel fire-resistant coatings Tunnel fire-resistant coatings are sprayed on the surface of the vault and side walls of the tunnel to protect against fire and heat insulation. It prevents the reinforced concrete in the tunnel from heating up rapidly in the fire and reducing its strength, and avoids concrete explosion and damage to the steel lining. Loss of supporting capacity caused the tunnel to collapse.
Transparent fire-retardant coatings Transparent fire-retardant coatings are mainly used on flammable plastic substrates. After use, they can maintain the original texture and color of the substrate, and have good fire and heat insulation properties.
Outdoor fire-retardant coatings Outdoor fire-retardant coatings refer to fire-retardant coatings suitable for outdoor environmental conditions. This kind of fireproof coating not only has the function of fire protection, but also should have good weather resistance and physical and chemical properties.
Classified by the role of materials
One of the key ingredients of fire retardant coatings is flame retardant. The selected flame retardant must be able to cooperate with the base material and other components of the fire protection system. For intumescent fire retardant coatings, it expands and foams when exposed to fire to form a uniform and dense insulation layer. In addition, economic efficiency must be considered. In addition, there is basically hs code for micronized wax no toxic gas and dense smoke during a fire, and basically no effect on the physical properties of the fire-retardant coating. There are many kinds of flame retardants that can be used in fire retardant coatings and fire retardant liquids, with different performances. The classification of flame retardants is briefly introduced below.
Flame retardants can be divided into two categories: organic and inorganic. According to the composition, it can be roughly divided into halogen-based flame retardants and phosphorus-based flame retardants; according to the way of introduction, it can be divided into additive and reactive flame retardants. There are four types of flame retardants used as additives: halide, phosphoric acid ester, halogen-containing phosphoric acid ester and inorganic compound. Most reactive flame retardants contain flame retardant elements such as halogen, nitrogen, and phosphorus, which can be regarded as monomers and bond with other materials during the resin synthesis process to form flame-retardant polymers.
