Mold, is the use of a particular shape and size of the production of a finished tool, it has been widely used in a variety of materials processing industries, such as forging metal forming mold using sand casting or casting molds, metal pressure processing used cold mold and various molding ceramic, glass, plastic and other use, etc., visible mold in today's industrial production, has a very important role, knowledge of this aspect, it is necessary, following the talk, it is to use gypsum produced Several simple molds to produce several pieces. Gypsum powder, wholesale plaster mold, said hemihydrate gypsum or plaster of Paris (2CaSO4 · H2O) in the chemical, is a natural abundance of gypsum mine CaSO4 · 2H2O is heated to 150 degrees to 170 degrees lose crystal water contained 3 / 4 and had changed. 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, the proportion of gypsum powder and water is about 2: 3, plaster mold where to sell, too much water, the fastness of solidified poor; if you need strength, they put plaster of Paris. When installing plaster mold, for uneven places often find a way to come to the flat. Specifically how to do it? Plaster mold experts here and share with you: 1, if the flatness of the wall is not compliant, that is, within about 5 mm, is to pass putty, plaster mold, can not control the flatness of about 3 mm or less It also works on the renovation of a wall roughness acceptance criteria. 2, if the flatness of the wall is not greater than 2 cm, with whitewashed plaster and cement mortar, or even different hanging ratios, it is still because of thick walls lead to cracking in the future, so they can only be used gypsum board that which hit the wooden keel, gypsum board outside cover of the method came to the flat wall. 3, if the wall is not greater than 8 mm flatness, leveling putty is a thick wall can cause cracks in the future, it is to switch to leveling the special material "wall plaster" came the flat wall or cement mortar. When the unevenness between 5 mm to 1 cm, can be wall plaster or cement mortar direct leveling; when unevenness between 1 cm to 2 cm, after looking over hanging with wall plaster layer of nylon mesh, plaster mold wholesale, wall plaster and then find it again later, or use the ratio of 1: 2 cement mortar to find it again, so it is possible to prevent the leveling layer is too thick walls lead to cracking in the future.
