Did you choose the right fireproof paint for your home?

作者: Release Date: 2019-06-19 Author: Click:

When I heard of fire-resistant coatings , what would come to mind in fire-resistant coatings, why should I choose this coating and how to choose it in Tianjin fire-resistant coatings ? First, let's take a look at what is fire-resistant paint. Fire-resistant coating is to paint the surface of those flammable materials, which can improve the fire resistance of the material, slow down the speed of flame propagation, or prevent combustion for a certain period of time. This type of coating is called fire-resistant coating , or flame-retardant coating . Fire-resistant coatings are inherently non-combustible or non-combustible, so that the protected substrate is not in direct contact with the air, delaying the ignition of objects and reducing the rate of combustion. You should know that. So what should I choose?

天津防火涂料

Broadly divided into these types:

Steel structure

As a form of high-rise building structure, steel structure is widely used in the construction industry for its high strength, light weight, good extensibility, seismic resistance, and short construction cycle, especially in super high-rises and large span Showing strong vitality in architecture and other aspects

Thick coating

8 45mm 的涂料,这类防火涂料的耐火极限可达 0.5 3h The thick coating type steel structure fireproof coating refers to the coating with a coating thickness of 8 to 45mm . The fire resistance limit of this type of fireproof coating can reach 0.5 to 3h . In a fire, the coating does not swell. Depending on the material's non-combustibility, low thermal conductivity, or the heat absorption of the material in the coating, the temperature of the steel is delayed, and the steel is protected at a lower cost.

Thin coating

3 7mm 的钢结构防火涂料称为薄涂型钢结构防火涂料。 Steel structure fireproof coatings with a coating thickness of 3 to 7mm are referred to as thin-coated steel structure fireproof coatings. This type of coating can expand and foam when exposed to fire, and the fire-resistant insulation layer formed by the expanded foam can delay the temperature rise of the steel and protect the steel components. This type of steel structure coating is generally composed of a suitable latex polymer as a base material, and then combined with a flame retardant, an additive and the like.

cable

20 世纪 70 年代末和 80 年代初,它是在饰面型防火涂料基础上结合自身要求发展起来的,其理化性能及耐候性能较好,涂层较薄,遇火能生成均匀致密的海绵状泡沫隔热层,有显著的隔热防火效果,从而达到保护电缆、阻止火焰蔓延、防止火灾的发生和发展的目的。 The development of China's cable fire-resistant coating products began in the late 1970s and early 1980s. It was developed on the basis of decorative fire - resistant coatings in combination with its own requirements. Its physical and chemical properties and weather resistance are better, and the coating is thinner. In the event of fire, it can generate a uniform and dense sponge-like foam insulation layer, which has a significant heat insulation and fire prevention effect, so as to achieve the purpose of protecting cables, preventing the spread of flame, and preventing the occurrence and development of fire.
