Beijing Lingying Technology Development Co., Ltd. specializes in the production, sales and construction of fire-resistant coatings for many years. Now it has systematically summarized the advantages and disadvantages of the performance of steel structure fire-resistant coatings, as follows:
(1) Fireproof coating for thick steel structure
Thickness: 8mm ~ 50mm.
放出有害人体健康的有毒气体和烟气；袋装出厂，运输方便。 Advantages: high fire resistance limit, up to 3h; main components are inorganic materials, relatively good durability; wide source of raw materials, low price, low unit price of products; no toxic gases harmful to human health will be emitted after fire Flue gas; Packed out of the factory, easy to transport.
期长； 水泥基涂料需要养护。 Disadvantages: The coating is thick and self-heavy, and it is easy to fall off when the adhesion is not good; the surface is rough, and the decoration is poor; the coating is thick, and it needs to be reinforced with metal wire mesh during construction, which increases the construction cost and the construction cycle ; Needs conservation.
(Two) thin steel structure fireproof coating
Thickness: 4mm ~ 7mm.
，抗挠曲性强；耐火极限最高可达2小时。 Advantages: thin coating, light weight, good adhesion; smooth surface and strong decoration; less unit area and low price; simple construction, no need for metal mesh reinforcement, fast drying; strong vibration and flex resistance ; Fire resistance up to 2 hours.
化，耐久性有待进一步研究；用于室外的产品不多，有待研究开发。 Disadvantages: The fire resistance limit is lower than that of thicker coatings; the main components of organic materials may release harmful gases and fumes when exposed to fire, which is for further study; because the main components are organic materials, the aging resistance and durability need to be further studied; There are not many products for outdoor use, which need to be researched and developed.
(Three) ultra-thin steel structure fireproof coating
Thickness: 3mm or less.
Advantages: The coating is thinner, and the decorative thin coating is better. The color can be adjusted according to your own preferences, which can achieve the effect of general architectural coatings. It also has the advantages of thin coatings.
Disadvantages: There are also disadvantages of thin coatings.
