保溫材料按照材質(zhì)組成來劃分，大致可以分為兩大類：一是有機聚合物絕熱材料，如發(fā)泡聚苯乙烯泡沫板、硬質(zhì)聚氨酯泡沫板等；二是無機保溫材料，如巖棉、玻璃棉、泡沫玻璃板等。其中，以巖棉、玻璃棉為代表的礦物棉因具有其他保溫材料所不具有的優(yōu)點。

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.

在保溫材料行業(yè)內(nèi)備受推崇，產(chǎn)量一直呈現(xiàn)逐年上升的態(tài)勢。其中巖棉以其更高的耐火極限和熔點溫度，在建筑保防火保溫方面更受青睞，近幾年來，產(chǎn)量呈一路增長態(tài)勢。

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.

巖棉是目前使用量大、增長快的無機保溫材料。那么究竟什么是巖棉？巖棉是不是一種綠色的保溫材料？本文將從巖棉的特點、應(yīng)用和生產(chǎn)等方面進行闡述。

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.

隨著人民生活水平的提高，對居住舒適度的追求和國家對建筑節(jié)能的要求，巖棉開始在建筑上得到應(yīng)用，主要用于辦公及公共建筑的屋面保溫、內(nèi)墻保溫及防火門和彩鋼夾芯板等。但由于巖棉價格相對較高，建筑商更愿意使用有機泡沫類的保溫材料，巖棉沒有得到大規(guī)模的推廣和應(yīng)用，產(chǎn)品質(zhì)量也是參差不齊。

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.

但隨之而來的幾場大火，使人們認識到不燃保溫材料的重要性，國家也相繼發(fā)布了一系列建筑防火安全的法規(guī)和文件，規(guī)定用于高層建筑和公共建筑的保溫材料一定使用A級不燃材料。

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.

為滿足巖棉板拉伸強度的要求，必須在集棉設(shè)備上增加擺錘，以改善巖棉板的平面鋪層，形成纖維層之間相互勾連交錯的三維結(jié)構(gòu)板狀制品，也使制品的密度均勻性大大提高；為降低吸水率和吸濕率、提高憎水率，必須采用具有較強憎水效果的粘結(jié)劑；

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;

為滿足標準中對纖維直徑和渣球含量的要求，必須對熔化、成纖設(shè)備進行改造升級；為滿足對巖棉板尺寸精度的要求，必須采用高精度無塵切割技術(shù)。

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.
