保温材料按照材质组成来划分，大致可以分为两大类：一是有机聚合物绝热材料，如发泡聚苯乙烯泡沫板、硬质聚氨酯泡沫板等；二是无机保温材料，如岩棉、玻璃棉、泡沫玻璃板等。其中，以岩棉、玻璃棉为代表的矿物棉因具有其他保温材料所不具有的优点。

According to the material composition, insulation materials can be divided into two categories: organic polymer insulation materials, such as foamed polystyrene foam board, rigid polyurethane foam board, etc. The two is inorganic thermal insulation materials, such as rock wool, glass wool, foam glass plate and so on. Among them, mineral wool represented by rock wool and glass wool has the advantages that other insulation materials do not have.

在保温材料行业内备受推崇，产量一直呈现逐年上升的态势。其中岩棉以其更高的耐火极限和熔点温度，在建筑保防火保温方面更受青睐，近几年来，产量呈一路增长态势。

It is highly praised in the thermal insulation material industry, and its output has been increasing year by year. Among them, rock wool with its higher fire resistance and melting point temperature is more popular in building fire protection and thermal insulation. In recent years, the output has been growing all the way.

岩棉是目前使用量大、增长快的无机保温材料。那么究竟什么是岩棉？岩棉是不是一种绿色的保温材料？本文将从岩棉的特点、应用和生产等方面进行阐述。

Rock wool is a kind of inorganic thermal insulation material with large usage and rapid growth. So what is rock wool? Is rock wool a kind of green thermal insulation material? This paper will elaborate the characteristics, application and production of rock wool.

随着人民生活水平的提高，对居住舒适度的追求和国家对建筑节能的要求，岩棉开始在建筑上得到应用，主要用于办公及公共建筑的屋面保温、内墙保温及防火门和彩钢夹芯板等。但由于岩棉价格相对较高，建筑商更愿意使用有机泡沫类的保温材料，岩棉没有得到大规模的推广和应用，产品质量也是参差不齐。

With the improvement of people's living standards, the pursuit of living comfort and the national requirements for building energy conservation, rock wool began to be used in construction, mainly for office and public building roof insulation, interior wall insulation, fire doors and color steel sandwich panel. However, because of the relatively high rock wool prices, builders are more willing to use organic foam insulation materials, and rock wool has not been widely promoted and applied, and the quality of products is also uneven.

但随之而来的几场大火，使人们认识到不燃保温材料的重要性，国家也相继发布了一系列建筑防火安全的法规和文件，规定用于高层建筑和公共建筑的保温材料一定使用A级不燃材料。

But the following several fires make people realize the importance of non combustible thermal insulation materials. The state has also issued a series of regulations and documents on building fire safety, stipulating that the thermal insulation materials used in high-rise buildings and public buildings must use class a non combustible materials.

为满足岩棉板拉伸强度的要求，必须在集棉设备上增加摆锤，以改善岩棉板的平面铺层，形成纤维层之间相互勾连交错的三维结构板状制品，也使制品的密度均匀性大大提高；为降低吸水率和吸湿率、提高憎水率，必须采用具有较强憎水效果的粘结剂；

In order to meet the requirements of tensile strength of rock wool board, pendulum must be added to the cotton collecting equipment to improve the plane ply of rock wool board, form a three-dimensional structure plate product with interlaced fiber layers, and greatly improve the density uniformity of the product; In order to reduce the water absorption and hygroscopicity and improve the hydrophobicity, the binder with strong hydrophobic effect must be used;

为满足标准中对纤维直径和渣球含量的要求，必须对熔化、成纤设备进行改造升级；为满足对岩棉板尺寸精度的要求，必须采用高精度无尘切割技术。

In order to meet the requirements of fiber diameter and slag ball content in the standard, the melting and fiber forming equipment must be upgraded; In order to meet the requirements of dimensional accuracy of rock wool board, high-precision dust-free cutting technology must be adopted.
