The common colours of FRP grille are red, yellow, green, black and grey, etc. These colours are determined by increasing the colour and quantity of pigments in the production process.
With the new material gradually entering people's life and production, we also know that FRP grille is a kind of building material. FRP grille is made of glass fiber as reinforcing material (commonly known as skeleton), unsaturated resin as matrix, cured at high temperature after a specific time, its acid and alkali resistance, aging resistance, insulation, high load-bearing, color. Bright, long service life, has become a unique bright spot.
The common colours of FRP grille are red, yellow, green, black and grey, etc. These colours are determined by increasing the colour and quantity of pigments in the production process. The amount of pigments added is generally 1%~5% of the resin quality. The curing of unsaturated polyester resin with different pigments in FRP grids can be accelerated by some pigments and inhibited by others. Therefore, when choosing pigments paste, we should pay attention to their influence on curing speed of resin.
Therefore, the color of FRP grille is not a layer of surface, but is made by mixing the color paste into all the resins. It has the characteristics of diverse colors, uniform coloring and not easy to fade.
But everything has its advantages and disadvantages, and FRP grille is no exception. FRP grille will not fade in indoor use all the year round, but it will fade in outdoor exposure. But it will not affect the normal use of FRP grille, but the color of the grille is not so bright and quality. Quantitative grids will also fade slightly within 2 years, and sub-quality grids will fade in a few months. If the FRP grille is exposed to the sun all the year round outdoors, the grille grey can be chosen, so there is no obvious difference; or if it is selected according to the use all the year round outdoors, the pattern cover can be added, which can increase the intensity and also resist ultraviolet rays.
