Whether it is a conventional product or a specially customized functional gypsum board with fireproof, waterproof, soundproof and other functions, it can be produced efficiently.Product Description II. In-depth Analysis of the Production Process1.Selection and Pretreatment of Raw MaterialsGypsum Raw Materials: Strictly select high-quality gypsum ore sources to ensure the purity and quality of the raw materials. Through advanced crushing and grinding equipment, the gypsum ore is processed into gypsum powder with uniform particle size and meeting the production requirements.Auxiliary Materials: Conduct fine inspection and pretreatment of auxiliary materials such as modified starch, retarder, and foaming agent to ensure their stable performance and reliable quality. Store and transport them according to the precise formula to provide accurate raw material support for the subsequent ingredient process.2.Precise Ingredient and Efficient MixingAdopt high-precision metering equipment to quantitatively measure each component of the raw material slurry (modified starch, retarder, pulp, water reducer, water), put them into the hydraulic pulper and stir them into a uniform and stable raw material slurry, and then pump it into the slurry storage tank.Mix the foaming agent and water in a specific ratio in the foaming agent preparation tank, pump them into the foaming agent storage tank with a heating device, and maintain the temperature above 35°C to ensure the foaming effect.The accelerator and gypsum powder are fed into the silo through the lifting and conveying equipment. During the ingredient process, the slurry, foaming agent, accelerator and gypsum powder are accurately fed into the mixer through the automatic metering device and fully mixed to form a gypsum slurry that meets the process requirements. The whole ingredient process is adjusted in real time by the intelligent control system according to the production line speed to ensure the consistency of product quality.3.Precise Molding and Stable SolidificationThe upper paper and the lower paper are respectively unrolled by the uncoiler, and then accurately enter the molding machine through equipment such as the automatic edge aligner and notching machine. The gypsum slurry output from the mixer is evenly dropped onto the lower paper on the vibration platform and enters the molding machine to be extruded and molded into a gypsum board blank of a specific specification.The gypsum board blank completes the initial setting on the setting belt, initially solidifying its shape; and completes the final setting on the conveying roller table to reach a certain strength. Then it is cut into the set length (such as 2400mm, 3000mm or the length customized by the customer) by the fixed-length cutting machine, and then turns through the No. 1 transverse machine, adjusts the spacing through the approaching roller table, and is sent into the dryer by the distributor.4.Efficient Drying and Energy-saving DesignThe drying system adopts an advanced fuel oil type heat-conducting oil furnace as the heat source. The hot oil is converted into hot air through the fin heat exchanger and is sent into the interior of the dryer by the high-efficiency fan. The dryer is designed with two zones. According to the drying characteristics of the gypsum board, it precisely controls parameters such as temperature and wind speed to achieve efficient drying and avoid phenomena such as overburning or insufficient drying. This drying process is environmentally friendly, energy-saving, has high thermal efficiency, and effectively reduces production costs.5.Fine Post-processing and Quality AssuranceThe dried gypsum board is sent to the No. 2 transverse system by the plate discharging machine for fixed-length trimming to cut off the redundant edge parts and ensure the dimensional accuracy of the board; use automatic edge wrapping equipment to wrap the edges of the gypsum board to enhance the edge strength and aesthetic appearance of the board.The gypsum board is sent to the automatic stacker by the finished product conveyor and stacked according to the set method. After the stacking is completed, it is transported to the packaging area by a forklift for strict quality inspection and packaging to ensure that the products leaving the factory meet high-standard requirements.III. Product Performance Highlights1.Outstanding Safety and Fireproof Performance: When a fire occurs, the crystal water in the main component of the paper-faced gypsum board, calcium sulfate dihydrate, decomposes and absorbs a large amount of heat, delaying the temperature rise of the board. The water vapor generated during the decomposition forms an isolation layer, effectively preventing the spread of flames. Its fire resistance is far higher than that of ordinary building materials, providing reliable fire protection for buildings.2.Good Comfort Performance: The product has a low thermal conductivity, between 0.20 - 0.28W/m·K, similar to that of wood. This gives the paper-faced gypsum board a "warm" characteristic, which can effectively adjust the indoor temperature and create a comfortable indoor environment. At the same time, it has a certain "breathing function", which can adjust the indoor humidity and improve the living comfort.3.Remarkable Environmental Protection Features: The production line pays attention to resource conservation and environmental protection, adopts energy-saving equipment and processes during the production process, and reduces energy consumption. Some raw materials can be recycled, reducing waste emissions, in line with the development trend of green building materials and contributing to the sustainable development of buildings. IV.

From raw material measurement, ingredient mixing, molding and solidification to drying treatment and subsequent processing, the whole process realizes automated and precise control. The system can automatically adjust the parameters of each link according to the production speed, reducing manual operation errors. At the same time, it has a fault early warning function. Once an abnormality occurs, it can stop the machine in a timely manner and send out an alarm, making it convenient for maintenance personnel to quickly locate the problem, thus ensuring the stable and continuous progress of production.Q5. How does the fireproof performance of the paper-faced gypsum board meet the national standards?A:The main component of the paper-faced gypsum board, calcium sulfate dihydrate, decomposes crystal water to absorb a large amount of heat during a fire, delaying the temperature rise of the board. The water vapor generated during the decomposition forms an isolation layer to block the spread of flames. Our production line is strictly produced in accordance with the national standard GB 9775 - 2008. Every link, from raw material proportioning, production process to finished product inspection, is strictly controlled to ensure that the fire resistance performance of the product meets the standards.Q6. How to ensure the consistency of the quality of gypsum boards produced in different batches?A:This is achieved through a complete quality control system. On the one hand, strict inspection and standardized pretreatment of raw materials are carried out to ensure the stable quality of each batch of raw materials. On the other hand, the automated control system precisely controls the production process parameters, such as ingredient proportion, mixing time, drying temperature, etc. At the same time, multiple quality inspections will be carried out before the finished products leave the factory, including the inspection of indicators such as strength, thickness, flatness, and water absorption rate. Only qualified products can leave the factory.
