7.2-Meter AAC Panel Production Line

In 2020, driven by the strong promotion of prefabricated buildings, the application prospects for 7.2-meter AAC panels in large-scale projects became highly promising. Relying on its provincial-level R&D center, Sunite independently developed and produced the 7.2-meter large panel production line. Currently, three such lines are in operation. This production line covers all panel sizes available on the market and can manufacture panels of any size up to 7.2 meters.

Cloud-Based Equipment Maintenance System

This remote maintenance system is designed for newly installed equipment, effectively addressing the maintenance and servicing needs of customers' automation control systems. It enables online monitoring of motor current and temperature changes, provides historical motor operation data, issues alarms when thresholds are exceeded, and remotely resolves PLC faults. This system effectively addresses the challenge faced by customers lacking automation control professionals.

Low-Temperature Condensate Heat Energy Cascade Utilization System

The utilization of condensate and waste steam is a critical aspect of the autoclave curing process. Since condensate and waste steam retain substantial thermal energy, their reuse is especially significant in today’s context of heightened emphasis on energy conservation and environmental protection. Based on the principles of energy conservation and the second law of thermodynamics, Sunite has developed a dynamic steam heat energy cascade utilization system. This system enables the repeated, dynamic reuse of steam energy and has been implemented across various industries.

Installing this system optimizes the production process and yields significant benefits:

·       Complete recovery of all waste steam from the autoclave, with zero steam discharge;

·       Full recovery of condensate, achieving zero discharge;

·       No fresh steam is required for the pre-curing and static curing chambers, as indoor temperatures meet process requirements;

·       Recovery equipment is fully automated;

·       Recovery equipment operates with near-zero power consumption.

After cooling, the low-temperature condensate is used directly in production, eliminating wastewater discharge and supporting clean production. The system achieves an average energy-saving rate of 20–30%, depending on specific processes and products, and significantly reduces production costs.

Automatic Recipe Generation System

Lime and cement are transported by screw conveyors to their respective powder weighing scales. Slurry, gypsum slurry, additional water, and waste slurry are measured by liquid weighing scales and simultaneously fed into the mixer. Aluminum powder is pre-made into a suspension and added into the mixer after measurement. The resulting mixture forms the casting slurry.

The raw material formula, operational sequence, and process timing are fully controlled by computer. The batching process and related parameters are displayed on a computer screen. The prepared slurry is automatically poured into molds via a casting chute according to the preset program.

The system automatically measures the specific gravity of the slurry and waste slurry, calculating the required amount of additional water. Before entering the weighing scale, specific gravity values are recorded. Based on process requirements, the system consults its database and performs internal calculations to determine the necessary quantities of added water and aluminum powder. It then generates a recipe, compares it to the preset formula, and issues an alert if discrepancies are detected. If no discrepancies are found, the casting process proceeds, effectively improving casting yield.

The system includes casting record and statistics functions, recording data for each mold and offering various options for retrieving historical casting data and summary statistics.
