The prefabricated terrazzo manufacturing process is a complex process involving multiple steps that requires careful design and precise operation. Here are the detailed steps of the prefabricated terrazzo manufacturing process:
1. Preparation of raw materials.
The first step in the manufacture of prefabricated terrazzo is to prepare the raw materials, including cement, sand, crushed stone, pigments, etc. The quality of these materials has a direct impact on the performance and appearance of the final product. Therefore, when selecting raw materials, it is important to ensure that their quality meets the relevant standards and requirements.
2. Ingredients and stirring.
Batching and mixing is one of the key links in the manufacture of prefabricated terrazzo. According to the production needs, cement, sand, gravel, pigments, etc. are mixed in proportion, and an appropriate amount of water is added for stirring, so that various raw materials are fully integrated to form a uniform and consistent mixture. During the mixing process, attention should be paid to controlling the moisture content, so as not to affect the hardening and wear resistance of the terrazzo.
3. Paving and maintenance.
The mixed mixture is laid in a prefabricated formwork and smoothed with a trowel or by hand to make its surface flat. After the pavement is completed, the terrazzo should be cured to maintain the appropriate temperature and humidity to make it fully hardened. The curing time should be determined according to the specific situation, generally about 28 days.
4. Grinding and polishing.
After curing, the terrazzo is ground and polished to obtain a smooth and delicate surface. During the grinding and polishing process, sandpaper or abrasives with different mesh numbers should be selected according to the needs to gradually improve the surface finish. When polishing, a polishing machine or manual operation can be used to make the surface of the terrazzo achieve the desired gloss.
5. Inspection and packaging.
Finally, the quality inspection of the prefabricated terrazzo is carried out to ensure that its appearance, size and performance meet the requirements. Qualified products can be packaged for transportation and storage. When packing, appropriate protective measures should be used to prevent terrazzo from being damaged during transportation.
The above are the main steps of the prefabricated terrazzo manufacturing process. Through strict control of raw material quality, precise batching and mixing, reasonable curing, careful grinding and polishing, quality inspection and packaging, etc., high-quality prefabricated terrazzo products can be produced. This kind of product is widely used in the ground, wall, column and other construction fields, with beautiful and durable, wear-resistant and anti-slip characteristics. At the same time, the continuous improvement and innovation of the prefabricated terrazzo manufacturing process will also promote the sustainable development of the construction industry.
