在济南的工业与建筑材料领域，石膏粉犹如一块低调却关键的基石，支撑起众多产业的发展。它凭借独特的物理化学性质，在建筑装饰、工业生产、艺术创作等多个领域发挥着不可替代的作用，成为济南经济发展中不可或缺的重要元素。​

In the industrial and building materials fields of Jinan, gypsum powder is like a low-key yet crucial cornerstone, supporting the development of numerous industries. It plays an irreplaceable role in various fields such as architectural decoration, industrial production, and artistic creation due to its unique physical and chemical properties, and has become an indispensable element in the economic development of Jinan. ​

独特特性奠定应用基础​

Unique characteristics lay the foundation for application

济南产出的石膏粉具有诸多优良特性。从物理性质看，它质地细腻，颗粒均匀，这使得在加工和使用过程中，能够均匀地混合与分散，保证产品质量的稳定性。例如，在建筑石膏制品的生产中，细腻的石膏粉能让制成的石膏板表面光滑平整，触感舒适，无论是用于墙面装饰还是天花板吊顶，都能呈现出美观的效果。石膏粉还具有良好的可塑性，在加水搅拌后，能迅速形成具有一定流动性的浆体，可根据不同模具塑造成各种复杂形状，为建筑装饰构件以及艺术雕塑的制作提供了极大便利。像在欧式风格建筑中常见的精美石膏雕花装饰，便是利用石膏粉的可塑性，通过模具浇筑而成，为建筑增添了典雅的艺术气息。​

The gypsum powder produced in Jinan has many excellent characteristics. From the perspective of physical properties, it has a delicate texture and uniform particles, which enables uniform mixing and dispersion during processing and use, ensuring the stability of product quality. For example, in the production of building gypsum products, delicate gypsum powder can make the surface of the gypsum board smooth and flat, with a comfortable touch. Whether used for wall decoration or ceiling, it can present a beautiful effect. Gypsum powder also has good plasticity. After mixing with water, it can quickly form a slurry with certain fluidity, which can be molded into various complex shapes according to different molds, providing great convenience for the production of architectural decorative components and artistic sculptures. The exquisite gypsum carving decoration commonly seen in European style architecture is made by using the plasticity of gypsum powder and pouring it through molds, adding an elegant artistic atmosphere to the building. ​

从化学性质来讲，石膏粉具有出色的防火性能。其主要成分硫酸钙在高温下会发生脱水反应，吸收大量热量，从而延缓周围环境温度的上升，阻止火势蔓延。这一特性使得石膏粉在建筑防火领域应用广泛，如在建筑隔墙、防火门芯板等材料中，石膏粉是重要的防火阻燃添加剂，大大提高了建筑物的消防安全性能。此外，石膏粉还具有一定的吸湿性，能够调节室内湿度。当室内空气湿度较高时，石膏粉会吸收空气中的水分；而在空气干燥时，又会释放出一定水分，保持室内湿度相对稳定，为人们创造舒适的居住和工作环境。​

In terms of chemical properties, gypsum powder has excellent fire resistance. Its main component, calcium sulfate, undergoes dehydration reaction at high temperatures, absorbing a large amount of heat, thereby delaying the rise of ambient temperature and preventing the spread of fire. This characteristic makes gypsum powder widely used in the field of building fire prevention, such as in building partition walls, fireproof door core panels and other materials. Gypsum powder is an important fire-resistant and flame-retardant additive, greatly improving the fire safety performance of buildings. In addition, gypsum powder also has a certain degree of moisture absorption, which can regulate indoor humidity. When the indoor air humidity is high, gypsum powder will absorb moisture from the air; When the air is dry, it releases a certain amount of moisture to maintain relatively stable indoor humidity, creating a comfortable living and working environment for people. ​

严谨生产工艺保障品质​

Rigorous production process ensures quality

济南拥有一批技术成熟、工艺先进的石膏粉生产企业。其生产工艺主要包括原料开采、预处理、煅烧、粉磨等环节，每一步都严格把控，以确保石膏粉的高品质。在原料开采阶段，企业注重对石膏矿的勘探与筛选，选取纯度高、杂质少的优质矿石。济南周边的石膏矿资源丰富，品质优良，为石膏粉生产提供了坚实的原料基础。开采后的石膏矿石首先进行预处理，去除表面的杂质和泥土，然后将其破碎成合适的粒度，以便后续加工。​

Jinan has a group of gypsum powder production enterprises with mature technology and advanced processes. The production process mainly includes raw material extraction, pretreatment, calcination, grinding and other links, and each step is strictly controlled to ensure the high quality of gypsum powder. In the stage of raw material mining, enterprises pay attention to the exploration and screening of gypsum mines, selecting high-quality ores with high purity and low impurities. The gypsum resources around Jinan are abundant and of excellent quality, providing a solid raw material foundation for the production of gypsum powder. The gypsum ore after mining is first pretreated to remove surface impurities and soil, and then crushed into suitable particle sizes for subsequent processing. ​
