Quality identification method for transparent fire protection coatings

China Paint Online News Information:
transparent fire protection paint is also known as fire varnish, is a type of finish fire protection paint. Transparent fire varnish finish type fire protection paint, the product is the introduction of foreign advanced technology, new formulations, new production technology developed, is a set of decorative and fire-resistant as one of the special coatings. It is mainly used for fire protection of high-quality wood decorative materials and steel surfaces of buildings or structures. Its products should comply with the national standard GB12441-1998 finish type fire protection coating general technical conditions and GB14907-2002 "steel structure fire protection coating general technical conditions" requirements.is commonly used in China's fire-resistant paint are expansion type, mainly used in wood decorative materials surface. When the surface of an object coated with fire-resistant paint catches fire, the fire-resistant layer can bubble rapidly and expand rapidly in a short period of time, slowing down the development of combustion.the appearance of fire-resistant paint and ordinary paint is very similar, it is difficult to distinguish from the appearance, but also difficult to check the quality of fire-resistant paint on the spot. In experimental engineering, fire supervision departments at all levels can be identified by the following methods.1, according to national standards, in addition to meeting the fire resistance requirements, fire paint combustion performance is divided into one and two levels. Under the prescribed experimental conditions, the fire-resistant time of the first-grade fire-resistant paint is not less than 20min, and the fire-resistant time of the second-grade fire-resistant paint is not less than 10min. 2, check whether the product has a state-level fire quality inspection center issued by the qualified inspection report, can also be queried online. At present, fire-resistant paint to implement the fire-fighting product form recognition system, the market sales of fire-resistant paint should have the national fire-fighting product form recognition certificate and form inspection pass report.3, fire-resistant paint site construction should be the manufacturer's product packaging instructions, generally do not need to dilute with water, brushing on, brushing volume is not less than 500g/m2.4, the current domestic enterprises to produce fire resistance to the second level of fire paint, its cost price in 8000 yuan / ton or more, such as sales below this, the quality is worrying.5, the actual use, in order to ensure fireproof paint and other use performance, generally need to use a transparent cover coating. The amount of fire-resistant paint is generally 350 to 500g/m2, and the amount of cover coating is generally 50g/m2. Buy a house, buy a house, decorate a forum, a real estate forum 6x5u. 4x (i 6, the quality of the product can be done on-site preliminary inspection: in the construction of the substrate cut two or three small samples, or take a small number of samples coated on plywood, according to the actual construction of the situation painted. Under normal circumstances, according to the prescribed dosing (generally 500g/m2) construction, the foam thickness of the first-level fire-resistant paint is more than 20mm, the foam thickness of the second-level fire-resistant paint is more than 10mm, the foam layer should be uniformly dense. After drying out, check with the flame of the alcohol lamp.Fire-resistant paint in the heat of a strong fire, will be a large number of foam expansion, surface accumulation, within minutes will not appear burning damage phenomenon, and fake and inferior fire-resistant paint is basically non-foaming, there will be a large number of scattered slag, wood substrate will soon occur burning damage phenomenon.
