How is the sandstone relief model made?

How is the sandstone relief model made?

Answer:

Such as gypsum slurry thickening and then hand up pasteFrom the beginning of the second times, from the gypsum slurry up on the thickness can be larger, and can be mixed to wait a few minutes after the gypsum slurry to gypsum slurry concentration and to thicken the paste. Paste the time to pay attention to step by step, so that the thickness of the various parts of the balance. General one-time female mold is the full size of the full size of the module, the small can be thinner. The edge of the module is on the side of the insert and the plaster is behind the other.
Step one: the surface of the gypsum slurry up to the sandstone reliefUse a rubber bowl from the pot in the gypsum slurry, hand in a bowl of gypsum slurry up to the thin sandstone relief surface. Can be from top to bottom, local first indentation sink.Step two: blow, blow up after but also in a layerLiao Jiaowan after the gypsum slurry to blow, voids and the gypsum slurry could generate real blow. In the case of bubbles, or clay surface texture should also be large fluctuation, blowing, make gypsum slurry tightly against the sandstone relief on the surface under the pressure of the wind. After blowing up to add a layer of gypsum slurry. The sandstone reliefs were covered with a layer of gypsum slurry, such as gypsum slurry has the morning of the initial setting, has been second times, as well as over when gypsum slurry pot may have initial condensation and thicken the available palm to gypsum paste. Best to concave and down the batter, because these parts are not well up, not easy to stick to the gypsum slurry.
Currently (referring to 2009) has been exploited in the world of Australian sandstone, India sandstone, Spanish sandstone, sandstone, etc.. Among them, the color, the pattern is most welcome by the architectural designer is the Australian sandstone. Australian sandstone is a kind of ecological environmental protection stone, its product has no pollution, no radiation, no reflection, no weathering, no discoloration, heat absorption, heat preservation, anti slip and other characteristics.
