Several simple molds to produce several pieces made with plaster. Gypsum powder and water in a ratio of approximately 2: 3, too much water, the fastness of solidified poor; if you need strength, they put plaster of Paris. Since the plaster has been condensed into a solid is unusable, gypsum from the liquid condenses into solid, there are time constraints, when located in the plaster mix, forming firing from the beginning to the action must be swift, but also to estimate in advance the good plaster The amount, how much how much mix. Gypsum and gypsum products, there is a common characteristic - extremely absorbent, store not too long a time. Because there is always more or less moisture in the air, Shandong plaster mold, especially in the rainy season and apricot, gypsum powder in the water will increase its quality to be poor, and this will reduce the fastness it solidified, speed up the time it condenses, marinated less than a few minutes became lumps, plaster mold Which is good, in the end, gypsum will not condense. To work with plaster casting, plaster mold must be dealt with appropriately, first dry the plaster mold brushing twice shellac bubble (bubble force of water), plaster mold to the surface of the porous gypsum blocking treatment. In turn, when the system must also be brushing release agent, so pour the plaster to stick together and do not die, the release agent with a soft soap, ordinary soap, vaseline and oil, etc., Vaseline and oils soft soap no good water . Vaseline is too thick, it will affect the sophistication of the mold, aluminum alloy plaster mold, Vaseline oils also easy to dirty gray smoke, affecting the quality of the work. Soapy practice - soap sliced, placed in water heated to melt and serve. 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.
