Our gypsum board production process adheres to strict technological standards throughout, achieving precise control over the entire process from raw materials to finished products. High-purity natural gypsum ore is carefully selected. After being crushed by a jaw crusher, it is sent to a rotary kiln for high-temperature calcination to generate hemihydrate gypsum, ensuring the stability of raw material activity.
The pulping process adopts an automated proportioning system to precisely mix hemihydrate gypsum, modified additives and purified water. Through high-speed stirring, a uniform and fine gypsum slurry is formed, ensuring the strength and toughness of the board. During the forming stage, relying on the continuous forming machine imported from Germany, the slurry is evenly spread between the high-strength environmentally friendly facing paper, and then flattened and positioned for cutting by the extrusion roller to ensure that the thickness tolerance of the board is controlled within ±0.5mm.
The drying and curing process adopts a segmented constant-temperature drying kiln. Through an intelligent temperature control system, the temperature and humidity are precisely regulated to ensure uniform evaporation of the internal moisture gradient of the board, preventing cracking and deformation. The finished products need to go through multiple inspection procedures such as non-destructive testing, size verification, and strength testing to ensure that each gypsum board meets international quality standards, providing customers with stable and reliable building materials.
| Comparison Dimension | Our Gypsum Board | Other Companies' Gypsum Board |
|---|---|---|
| Raw Material & Process Control | Select high-purity natural gypsum ore, adopt German-imported automated production lines, and implement intelligent temperature-controlled calcination and forming throughout the process. The raw material activity and board precision far exceed industry standards. | Mostly use ordinary gypsum raw materials, some rely on traditional production equipment, with insufficient process stability and poor control over raw material purity and board tolerance. |
| Core Product Performance | The board's transverse breaking strength is ≥2.5MPa, fire resistance limit reaches 240 minutes, noise reduction coefficient NRC is ≥0.95, moisture absorption rate is ≤3%, and comprehensive performance fully meets international standards. | Most performance indicators such as strength, fire resistance, and sound insulation are only at the basic qualification level, some indicators fluctuate greatly, and they are prone to deformation and mildew in humid environments. |
| Environmental Protection Level & Healthiness | Adopt ENF-grade environmentally friendly facing paper and formaldehyde-free additives, with formaldehyde emission ≤0.025mg/m³. Obtained multiple international environmental certifications and meets green building requirements. | Mostly meet E1-level environmental standards, some products have formaldehyde emissions close to the limit, and the quality of environmental additives varies. |
| Customization & Supply Capacity | Can customize gypsum boards with special sizes and performances according to customer needs, support small-batch flexible production, and deliver regular orders within 72 hours. | Single product specifications, weak customization capabilities, long delivery cycles for bulk orders, and prone to supply delays. |
| After-Sales Service & Technical Support | Provide professional installation guidance, construction plan optimization and after-sales quality assurance services, with an exclusive technical team responding to customer issues 24/7. | Imperfect after-sales service system, mostly only provide basic quality assurance, slow response to technical support, and lack construction supporting services. |
