Performance introduction of marine phenolic grilleTime to add:2018/6/25 16:39:25
USCG (US Coast Guard, namely : U.S. Coast Guard) combustion performance test is a very strict combustion test of FRP grating products. The test judges grille products from four aspects: flame retardancy, flame spread speed, smoke generation, and post-combustion bearing capacity. Due to the focus on escape ability in the event of fire, this test does not simply test whether the product passes or not in the "post-burning load" project, but also divides the test into different levels. ASTM E84, ASTM D-2836 Combustion test data: flame spread index¡Ü5, evaluated as: Class I limiting oxygen index¡Ý65 FRP molded grating and pultruded grating are generally used for platform, walkway construction and trench surface laying. Among them, the pultruded grid is more dependent on machine production, and the product performance is not easily affected by the skill of the workers, so it has more stable performance and also obtains a higher cost performance. Pultruded gratings are commonly used in subways (escape platforms), ships (side walkways, aerial walkways, decks and platform surfaces), sewage treatment plants (multiple laying), and customized FRP platforms are also our company's business. Phenolic grilles are used in major domestic projects such as Guangzhou Metro and Hangzhou Metro. Since phenolic resin has excellent properties in flame retardancy, low smoke toxicity and corrosion resistance, and the process requirements are more stringent, all indicators are significantly better than ordinary FRP gratings, and can also be used in chemical organic solvent environment. In addition, the company also provides flat grid, conductive grid to meet some special needs.
