Cement sculpture production process and matters needing attention

In recent years, the types of sculptures have become more and more, and the materials are also different. This also shows from the side that people's aesthetic needs are also increasing. Cement sculptures are strong, durable, and low cost. Cement sculptures are becoming more and more popular, and the advantages of cement sculptures have also promoted the development of cement sculptures. So, how are these cement sculptures made? Below, Beijing Sculpture Company will introduce you to the production process of cement sculptures and their attention Matters. 1. The production process of cement sculpture 1. Make a solid model of clay sculpture. Use clay or gypsum to make a 1:1 sculpture sample, and then fill in the small uneven surface of the solid sample with cement. 2. Make a mounting layer. Use an adhesive to mount and cover the glass cloth on the surface of the solid sample to form a mounting and covering layer composed of mounting and covering blocks, and horizontally segmented from bottom to top, and covering the two adjacent ones The joints of the blocks and the horizontal sections are provided with sub-ports for connection. 3. Make a soft cavity film and peel off the mounting cover layer, remove the glue filled on the surface of the solid sample, and then cover the mounting The layer restoration is combined on the surface of the actual sample, and the molding glue is injected into the cavity formed by the inner wall of the mounting cover layer and the surface of the real sample. After the molding glue is cured, the mounting cover layer and molding glue are removed, and the molding glue is bonded. A soft cavity mold is formed at the corresponding position on the inner wall of the laminated cover layer. 4. Pouring the cement mixture to assemble the horizontal soft cavity mold step by step from bottom to top, and pouring the cement mixture into the soft cavity mold in sections. At the same time, a frame is set up on the periphery of the soft cavity mold in sections, and sand is poured into the space formed by the frame and the surface of the soft cavity mold in sections until the pouring is completed. After curing, remove the sand and the frame, and then remove the soft cavity mold, finish the surface of the cement sculpture, and then make the cement sculpture product. 2. Cautions for the operation of cement sculpture 1. Avoid damp and hard cement. Reduce or even lose the original strength, so the specification stipulates that the cement that has been out of the factory for more than 3 months should be re-examined and tested and used according to the test results. For cement that has been damp or hardened, it must be sieved and used. It is generally used for masonry mortar or plastering mortar for secondary projects after being fine or crushed. 2. Avoid exposing quick-drying concrete or plastering if it is exposed to the sun after the operation. As the moisture evaporates quickly, its strength will be reduced. , Or even completely lost. Therefore, strictly clean and fully moisten the base layer before construction; after construction, it should be covered strictly, and watered and cured in accordance with the regulations. 3. Avoid negative temperature frozen concrete or mortar after mixing, if it is frozen, its Cement cannot be hydrated, and the water freezes and expands, and the concrete or mortar will be damaged by the gradually deepening of the powder from the surface to the inside.Therefore, the construction should be carried out in strict accordance with the ``Winter Construction Regulations for Construction Engineering'' (JGJ104-97). 4. Avoid the mortar layer or concrete components that have been solidified by high temperature and extreme heat. If they are often exposed to high temperature and extreme heat, there will be strength loss. This is because under high temperature conditions, the calcium hydroxide in the cement stone will decompose; in addition, some bones The material will also decompose or expand in volume under high temperature conditions. For long-term high temperature occasions, refractory bricks can be used to isolate and protect ordinary mortar or concrete. The above is about cement carvings. The introduction of the plastic production process and its precautions, I hope it can help you.
