Baotou GRC It refers to the glass fiber reinforced cement composite material, which is a composite material composed of Portland cement mortar and alkali resistant glass fiber, and also contains admixtures and admixtures. GRC Decorative lines belong to the most common component classification of GRC architectural detail decoration components. In a narrow sense, GRC decorative lines refer to: GRC cornice line, GRC door and window sleeve line, GRC waist line, GRC skirting line, etc. The generalized GRC decorative lines also include: GRC decorative columns, GRC treasure bottle railings, GRC arch rolls, etc.
GRC decorative line is a gas tight cementing material, so it should have a corresponding thickness, so that the intermolecular affinity can achieve a good effect, so as to ensure the relative service life and maintain integrity within the service life. The average thickness of good quality should be more than 8mm. If it is too thin, it not only has a short service life and poor safety performance, but also has a high damage rate during transportation and installation.
At present, some GRC decorative line products on the market, because of the one-sided pursuit of profits, take the means of making the edge thicker and the middle thinner to deceive consumers. There are two identification methods for such GRC decorative lines: one is weight identification. The standard weight of a piece of 10 cm wide and 2.44 m long is less than 2.3 kg, and different lengths can be calculated according to this ratio; The second is to check whether the thickness of the sawn section reaches 8mm.
Most GRC decorative lines are hollow, which ensures the characteristics of small dead weight and easy installation. The wall thickness of 15 and 20 mm, together with nylon mesh, ensures its overall rigidity and toughness, which is easy to ensure that the line effect will not be greatly deformed, while the toughness makes it more like reinforced concrete with overall shrinking strength and stiffness.
During the subsequent destruction, a number of plastic hinges are formed, which will not break suddenly, causing personal injury and damage to the building itself; At the same time, because of its convenient installation, compared with other decoration sub projects such as plastering, it has the advantages of shortening the overall construction period and not being affected by external conditions such as season, weather, temperature, etc.
