The production of calcium silicate boards follows a core logic of "raw material matching - molding and curing - fine processing," relying on standardized and intelligent processes to ensure product quality. Its core technological steps are clearly defined, with each step closely integrated. Guangdong Zhonghong's production line equipment can achieve precise matching across all process stages, helping companies efficiently mass-produce high-quality calcium silicate boards.

1. Raw Material Preparation: Using siliceous materials (quartz powder, silica sand, etc.) and calcareous materials (cement, lime, etc.) as core raw materials, combined with reinforcing fibers (waste paper pulp, mineral fibers, etc.), a qualified raw material slurry is produced through precise metering, mixing, ball milling, and sieving. This step is compatible with the company's automated batching and intelligent ball milling equipment, achieving precise and controllable raw material ratios, reducing material waste, and aligning with the concept of green manufacturing.

2. Pulping and Molding: Qualified raw material slurry is loosened, stirred, and stored. Using mainstream processes such as the flow-through or sheet forming methods, it is processed through equipment including a headbox, vacuum dewatering device, and roller press to form a slab with a certain strength and thickness. The company's molding equipment can flexibly adapt to the production of slabs of different specifications, achieving automated continuous molding, improving molding efficiency and slab flatness, and avoiding human error.

3. Autoclaving: As a key step in calcium silicate board molding, after pre-curing and demolding, the slab is sent to a high-pressure steam curing autoclave for high-temperature and high-pressure curing. This causes a chemical reaction in the raw materials to form a stable crystal structure, giving the board its core properties of fire resistance, moisture resistance, and high strength. The company's intelligent autoclaving equipment has functions such as parameter adaptive optimization, real-time monitoring, and automatic alarms. It can precisely control the curing temperature and pressure, shorten the curing cycle, reduce energy consumption, and ensure uniform and stable performance of each batch of boards.

4. Subsequent Processing and Inspection: After curing, the boards undergo automated cutting, sanding, punching, and surface finishing to meet the needs of different application scenarios. Finally, a full-process quality inspection is conducted to select qualified products for packaging and shipment. The company's subsequent processing equipment can achieve flexible cutting of multiple specifications, and combined with intelligent inspection equipment, it improves processing accuracy and inspection efficiency, helping enterprises reduce labor costs and increase yield, aligning with the intelligent development trend of the building materials industry.
