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. Several simple molds to produce several pieces made with plaster. Gypsum powder and water in a ratio of approximately 2: 3, too much water, how much money plaster mold, solidified fastness 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, 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, accelerate its clotting time , marinated less than a few minutes became lumps, plaster molds where to buy, in the end, gypsum will not condense. This decorative plaster material widely used in home decoration industry, Shandong plaster mold, is it a market promising a decorative materials, but plaster decoration materials have a problem that is often cracking phenomenon cracking plaster line will affect the appearance of the decorative effect will be greatly reduced. So, we need to understand the site often the case, make the appropriate security work at the time of installation. Ceiling easy to crack, Sichuan plaster mold with plaster mold ceilings and cement mortar as float or not a good combination and cracking phenomenon, there is Chuanglian seams cracking, cracking and tile joints parts, because Tile is smooth, so it is easy because a bad contact cracking, etc. are a common problem when it occurred, it does not mean there is a problem in itself plaster line quality. Only think of ways to overcome it! Sichuan plaster mold, Artel plaster mold, plaster mold by Shandong Gaomi Artel plaster mold factory. Sichuan plaster mold, Artel plaster mold, plaster mold is Shandong Gaomi Artel plaster mold factory (www.htsgmj.com) (www.htsgmj.com) this year introduced a new upgrade, the above picture is for reference only, please dial this Tel pages or pictures on obtain the latest information, contact: Du Jingli.
