(1) GRG is the abbreviation of Fiber Reinforced Gypsum Glass, the Chinese name is glass fiber reinforced gypsum board series products. Professional interpretation, it is used as the base material for rigid and dedicated enhanced glass fiber and some environmental protection additives made of pre cast new type of decorative materials GRG special gypsum - ultra fine crystalline gypsum (modified (gypsum). Popular point, that is, GRG high strength and high density of gypsum plus alkali resistant glass fiber additive, water, release agent production of pre cast molding products.

(2) then we understand the raw material, the most important is the gypsum powder and glass fiber.

High density and high strength gypsum, why should emphasize high density and high strength? Because we want to distinguish between other manufacturers, raw materials used, quality is guaranteed. Domestic counterparts more commonly used desulfurization gypsum powder or natural gypsum. Desulfurization gypsum is actually thermal power plants burn coal in the process of using flue filtering device, (calcium hydroxide) Ca (OH) 2 and (sulfur dioxide) reaction of SO2 (gypsum) CASO4 2H2O. However, this chemical reaction is not complete, there are a lot of impurities, such as, CASO3, CASO4, so, SO2 and SO3, ash, carbon. This is toxic.

Why do some GRG products after the installation, will be yellow smell it? Because it contains sulfur! GRG easy to be affected with damp, deformation, cracking and cracking. The shrinkage and the surface paint is not the same time for a long time, will be skin. Obviously, with the GRG, is not in line with the current needs of green environment protection, so that even if the product is done, the test can not go, no one likes to put toxic products all day long? While the natural gypsum with low strength and high water cut, the physical performance is not up to the standard of safety load, no one likes to put an unsafe time bomb in the head, right? There is also a beta half water gypsum powder, but the intensity is low, the density is not high, and the poor water permeability, nor is the choice of GRG materials. But why is it used? Is very simple, the raw material is less than 700 dollars a ton. Cheap And only natural, gypsum powder, in order to meet requirements of GRG, on the basis of natural gypsum, then the 3 pressure heating reaction can be obtained. But this material process equipment requires high, rely on imports. This is virtually invisible, the cost of raw materials is expensive! But the raw material has to ensure that the product is also a preliminary guarantee! The European standard uses the German import a half water gypsum powder.

Be careful, natural and natural gypsum powder, gypsum powder is not the same!

Glass fiber, glass fiber in the GRG product which is a messy scattered to the uniform distribution, equivalent to the keel, the popular point, it is equivalent to the human body's bone. Glass fiber of zirconia content must be more than 16%, at present domestic has Hubei Xiangfan Hui Erjie, neg abroad to Japan, Spain Syme Phil Fiberglass (CEM FIL) in order to meet this requirement. The high content of zirconia fiber to ensure alkali resistance. And a lot of GRG small factories, with the content of zirconia is not up to the standard of glass fiber, why not? Because glass is the production of re-use of waste glass recycling furnace, a lot of impurities, commander of the fiber can not be produced, pulled it off, only the production of staple. Lack of strength, expansion coefficient cannot with gypsum agreed in GRG products with the temperature changes, it is easy to loose, and gypsum combination degree is not high, its toughness is not enough, so the bending resistance of the GRG declined substantially. Made out of the GRG product greatly reduced, security risks. This product will hold in the ceiling above! Staple only alkali resistant to two or three thousand a ton, six thousand tons to Siwanduoyi!

:: <GRG / why expensive than others, expensive materials, in the quality, a penny.

(3) classification, according to my understanding, I am so divided.

A, flat panel, wall panels, reflective panels, perforated panels, and other arbitrary plate. Surface treatment effect can be polished, litchi, sand blasting, hair, skin, etc..

B, line series, is usually our understanding of the GRG plaster cast lines, shape, angle, flat line, etc., where we should pay attention to the ordinary cast lines mixed in this class.

C shaped series, carving, relief, openwork, Bao Liang, arc, ceilings, ceiling, who comes to the single surface, hyperboloid, three-dimensional covering a variety of art forms. Single supply GRG tablet prices also to three hundred or four hundred, but to see the use of the amount of! Involves single hyperbolic, multi surfaces, the price at least doubled, the price will be around one thousand Duoliangqianduo, calculated by square.

Prices in 60-300/ paint fluorocarbon paint, latex paint is here to add GRG general after installation to paint, paint can be used, such as diamond paint, metallic paint, wood paint, imitation gold paint, paint, but the most used.
