近些年来随着公共意识的增强，人们越来越关注于防火方面，现在在很多的场所都有着各种各样的防火措施，防火卷帘门作为一种有效的阻碍火灾蔓延的手段，在济南的应用十分广泛，那么在济南防火卷帘门内部一般都用什么来填充呢
In recent years, with the enhancement of public safety awareness, people pay more and more attention to fire prevention. Now there are a variety of fire prevention measures in many places. As an effective means to hinder the spread of fire, fire rolling shutter door is widely used in Jinan. What is generally used to fill the interior of fire rolling shutter door in Jinan
防火卷帘门的特点，我们知道这种门适合用在门洞口比较大的建筑物上，而且其防火隔热的效果也须达到现有防火门类产品的高等级。为了实现将两者功能的有效结合，在这种门的设计之中融入了防火门和卷帘门的重要元素，同时为了保证使用效果对门的结构进行的效果的优化，这才有现在大家看到的外观美观、性能优越、使用方便的产品。
According to the characteristics of fireproof rolling shutter door, we know that this kind of door is suitable for buildings with large door openings, and its fireproof and thermal insulation effect must reach the high level of existing fireproof products. In order to realize the effective combination of the two functions, the important elements of fire door and rolling shutter door are integrated into the design of this door. At the same time, in order to ensure the use effect, the effect of the door structure is optimized, which leads to the products with beautiful appearance, superior performance and convenient use.

现在山东市场上卷帘门以防火等级较高的卷帘门占主导，现在新出现的无机型产品更是打破一直以来传统卷帘门产品的垄断，很快成为了济南防火卷帘门市场上受优待的宠儿。
Now the rolling shutter door in Shandong market is dominated by the rolling shutter door with high fire rating. Now the new inorganic products break the monopoly of traditional rolling shutter door products, and soon become the favored child in Jinan fire shutter door market.
防火卷帘门之所以防火其中一大部分就在这种填充物上了，在常用的防火卷帘门的内部填充料中，石棉由于具有高抗张强度、高挠性、耐化学和热侵蚀、电绝缘和具有可纺性的矿物产品成为常用的填充料之一。石棉由纤维束组成，而纤维束又由很长很细的能相互分离的纤维组成。
A large part of the reason why the fireproof rolling shutter door is fireproof lies in this kind of filler. Among the commonly used internal fillers of the fireproof rolling shutter door, asbestos has become one of the commonly used fillers because of its high tensile strength, high flexibility, chemical and thermal erosion resistance, electrical insulation and spinnability. Asbestos is composed of fiber bundles, which are composed of long and fine fibers that can be separated from each other.
石棉具有的高度耐火性、电绝缘性和绝热性，使其成为重要的防火、绝缘和保温材料。硅酸铝耐火纤维棉有性能稳定，纤维长、抗拉强度大，渣球少等特点。产品广泛应用于纤维纺织制品原料、纤维喷涂、浇筑料、涂抹料原料、水法产品原材料、设备高温区域缝隙填充料。
Asbestos has high fire resistance, electrical insulation and thermal insulation, making it an important fire prevention, insulation and thermal insulation material. Aluminum silicate refractory fiber cotton has the characteristics of stable performance, long fiber, high tensile strength and less slag balls. The products are widely used in raw materials of fiber textile products, fiber spraying, pouring materials, coating materials, raw materials of water products and gap fillers in high-temperature areas of equipment.
在使用中，硅酸铝耐火纤维棉表现出了很多的产品特性：低热容量，低热导率;优良的热稳定性;优良的抗热震性能;优良的化学稳定性;不含结合剂和腐蚀性物质;优良的吸音性。种种产品特性都足以支撑和证明其能够作为防火卷帘门的合格填充料，稳定卷帘门的耐火性。
In use, aluminum silicate refractory fiber cotton shows many product characteristics: low heat capacity and low thermal conductivity; Excellent thermal stability; Excellent thermal shock resistance; Excellent chemical stability; Free of binding agents and corrosive substances; Excellent sound absorption. Various product characteristics are sufficient to support and prove that it can be used as a qualified filler for fireproof rolling shutter door and stabilize the fire resistance of rolling shutter door.
