It aims to provide high-quality paper-faced gypsum board products for the construction industry. All links from raw material input to finished product output are closely connected to ensure an efficient and precise production process.Product DescriptionII. Detailed Explanation of the Production Process1.Raw Material PreparationGypsum Powder: Select high-quality natural gypsum ore and finely grind it into gypsum powder that meets the production standards to ensure the stable quality of the products.Additives: Add modified starch, retarder, foaming agent, water reducer and other additives in precise proportions to optimize the performance of the gypsum board.Facing Paper: Select special facing paper with high strength and good water resistance to provide good protection and decorative effects for the gypsum board.2.Ingredient Mixing2.1.After quantitative measurement, modified starch, retarder, pulp, water reducer, water, etc. are put into a hydraulic pulper and stirred into a uniform raw material slurry, which is then pumped into the slurry storage tank for standby.2.2.The foaming agent and water are put into the foaming agent preparation tank in a specific ratio, stirred evenly, and then pumped into the foaming agent storage tank with a heating device (maintained above 35°C) for standby.2.3.The accelerator and gypsum powder raw materials are fed into the silo for standby through the lifting and conveying equipment.2.4.The slurry in the slurry storage tank is pumped into the mixer using a metering pump. The foaming agent enters the mixer after being foamed by the dynamic foaming device. The accelerator and gypsum powder enter the mixer after being metered by the automatic metering belt scale. All main and auxiliary materials are fully mixed in the mixer to form a qualified gypsum slurry. The addition of each main and auxiliary material is precisely controlled by the automatic control system and can be automatically adjusted according to the production line speed to meet the needs of large-scale and high-speed production.3.Molding and Solidification3.1.The upper paper is unrolled and enters the molding machine through the automatic edge aligner. The lower paper is unrolled and enters the molding machine through the automatic edge aligner, notching machine, and vibration platform. The slurry from the mixer falls onto the lower paper on the vibration platform and enters the molding machine, where the gypsum board of the required specifications is extruded.3.2.The gypsum board completes the initial setting on the setting belt and the final setting on the conveying roller table, and then is cut into the required length (such as 2400mm, 3000mm or other customized lengths) by the fixed-length cutting machine. After turning by the No. 1 transverse machine, the two gypsum boards leave the No. 1 transverse machine at the same time. After adjusting the spacing using the approaching roller table, they are distributed into the dryer by the distributor.4.Drying Treatment4.1.The drying part uses a fuel oil type heat-conducting oil furnace as the heat source. The hot oil exchanges hot air through the fin heat exchanger and is sent into the interior of the dryer by the fan to complete the drying task. The dryer is divided into two zones, which can precisely match the drying curve of the gypsum board, effectively avoiding defects such as overburning and incomplete drying. This process is environmentally friendly, energy-saving, has high thermal efficiency, and the process parameters are easy to control.5.Subsequent Processing5.1.The dried gypsum board is sent to the No. 2 transverse system by the plate discharging machine to complete the processes of fixed-length trimming and automatic edge wrapping.5.2.It is sent to the automatic stacker by the finished product conveyor for stacking. After the stacking is completed, it is transported to the packaging area by a forklift for inspection and packaging, and then the whole set of production processes is completed. III. Product Features1.Excellent Safety Performance: The final hydrated product of the paper-faced gypsum board is calcium sulfate dihydrate (CaSO4·2H2O). In case of a fire, the temperature will not rise above the decomposition temperature of 140°C until both crystal waters are completely decomposed. A large amount of water vapor curtain generated during the decomposition process can effectively block the spread of flames. Its fire resistance is 5 times higher than that of concrete and meets the relevant non-combustible body standards in China.2.Efficient and Fast Production: The initial and final setting time of general building gypsum is between 6 and 30 minutes. Compared with cement products, it has a faster setting and hardening speed. The demoulding cycle of the gypsum products produced by this production line can reach 4 to 5 times per hour. If the rapid gypsum calcination process is adopted, the setting time can be further shortened, greatly improving the production speed.3.Remarkable Energy Conservation and Environmental Protection: The production line pays attention to energy conservation and consumption reduction during the production process, adopts environmentally friendly processes and equipment, reduces energy consumption and pollutant emissions. At the same time, some raw materials can be recycled, which is in line with the concept of sustainable development.  IV.

What are the differences between different fuels?A:The applicable fuels for the production line include coal, natural gas, heavy oil, and diesel oil, etc. Coal has a relatively low cost, but it has a greater impact on the environment and requires supporting environmental protection treatment equipment; natural gas is clean and environmentally friendly with high thermal efficiency, but the cost of use is relatively high; heavy oil and diesel oil burn stably and also have good thermal efficiency, but the operation cost is higher than that of coal. You can choose according to the local energy supply, environmental protection policies, and cost budget.Q3. How much does the raw material preparation stage affect the product quality?A:Raw material preparation is the foundation for producing high-quality paper-faced gypsum boards. High-quality gypsum powder with high purity and uniform particle size can ensure the strength and stability of the boards; appropriate additives can optimize the performance of the boards. For example, the retarder controls the setting time, and the foaming agent affects the density and thermal insulation of the boards; high-strength and water-resistant facing paper enhances the integrity and durability of the boards. If the quality of raw materials in any link fails to meet the standards, it may lead to problems such as insufficient strength, deformation, and cracking in the finished products.Q4. How does the degree of automation of the production line ensure production stability?A:The production line is equipped with an advanced PLC programmable control system. 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.
