The plaster mold casting methods: ① the stirred gypsum slurry to pour a small portion of the mold, because it is a liquid, will flow set to a low recess, you must use the "keep out" approach, the mold everywhere including every corner, it can be boring into the gypsum slurry. ② the remaining gypsum slurry poured into the mold, generally small, it poured solid, which is filling the mold; large, hollow on the water, or a waste of gypsum, plaster mold wholesale component is also overweight, Bindu not necessarily good, hollow casting method is used, "sugar", the rotation of the mold of gypsum slurry slowly coagulate, so keep out three or four times the thickness of the plaster reaches one centimeter can be, if enhanced fastness, upheld in the inner layer of sticking a flax. ③ Pentagram sharp angle, when the release is very easy to Zhenduan. When casting can, plaster mold price, put a few thick layer of lead wires and flax, in order to increase the fastness. ④ until the plaster is completely solid, you can mold release, which is the key to success. Although coated with a release agent, but between the plaster mold and five-pointed star or stick very closely, together with the role of air pressure, the more difficult to disengage, the release method is to use a wooden mallet or block beat lightly, to shock the mold, so that they finally separated, at this stage must be patient and careful, you do not rush to help, or it may come to naught. Where the new mold, Guangxi plaster mold, mold release are generally more difficult, and more often used, Shandong plaster mold, mold release easier. Decorative plaster on the main board is used in industrial and civil construction and interior walls are decorated ceiling decoration, as well as within the wall is not load-bearing. Also it has a relatively light weight, high strength, fire resistance, sound insulation, toughness higher performance, but also for sawing, planing, processing, installation and construction of the nail, drill, sticky even more convenient. Sound-absorbing perforated gypsum board is mainly used in absorbing structure in the interior ceiling and wall. When used in wet environments, or for fire resistance will have higher requirements, we must use the appropriate proof, water-resistant or refractory substrates. Gypsum powder, said hemihydrate gypsum or plaster of Paris (2CaSO4 · H2O) in the chemical, is a natural abundance of gypsum mine CaSO4 · 2H2O and become heated to 150 degrees to 170 degrees, lose crystal water containing 3/4 a. A quantity of calcined gypsum mixed with water into a paste after solidification quickly, back into Ca-SO4 · 2H2O. We use gypsum oil flowing liquid into a solid plasticity, making molds and firing works, the whole course of the reaction about 15 minutes, will produce some heat, gypsum powder and water, the ratio is about 2: 3, too much water the fastness solidified poor; if you need strength, they put plaster of Paris.
