很多時候外墻巖棉板和擠壓板分不清，外墻巖棉板是擠壓板嗎？下面就一起來看看。外墻巖棉板以優質玄武巖和白云石為原料，將外墻巖棉板系列產品在1450℃下熔融，制成各種硬度的巖棉制品。巖棉板廣泛應用于有保溫、防火、隔音要求的場所。

Many times, the outer wall rock wool board and the Extrusion board are not clear, is the outer wall rock wool board extrusion board? Let's take a look. Using high quality basalt and dolomite as raw materials, rock wool board series products of external wall are melted at 1450 ℃ to make rock wool products with various hardness. Rock wool board is widely used in places with requirements of heat preservation, fire prevention and sound insulation.

巖棉纖維由于其纖細、柔韌的結構，具有抗壓強度高、抗拉強度高等特點。擠塑板是以聚苯乙烯樹脂為原料，經特殊工藝連續擠塑發泡而成的剛性板，其內部為獨立的密閉氣泡結構，是一種高抗壓、無吸水、防潮、環保的保溫材料，氣密、重量輕、耐腐蝕、使用壽命長、導熱系數低等優良性能。從這兩種材料的特點和使用場所來看，似乎都與一系列材料相似。

Because of its fine and flexible structure, rock wool fiber has the characteristics of high compressive strength and high tensile strength. Extruded board is a rigid board made of polystyrene resin by continuous extrusion and foaming by special process. Its interior is an independent closed bubble structure. It is a kind of high pressure resistant, non water absorbing, moisture-proof and environmental protection insulation material. It has excellent performance of air tightness, light weight, corrosion resistance, long service life and low thermal conductivity. From the point of view of the characteristics and places of use of these two materials, it seems that they are similar to a series of materials.

但從原材料和性能上看，外墻巖棉板屬于無機保溫材料，是以鐵渣為主要原料，經高壓蒸汽噴射熔化冷卻而成。是一種用聚苯乙烯樹脂和聚合物加熱并混合成催化劑的硬質泡沫板，然后擠出連續的硬質泡沫槽。

However, in terms of raw materials and properties, rock wool board of external wall belongs to inorganic thermal insulation material, which is made of iron slag as the main raw material and melted and cooled by high-pressure steam jet. It is a rigid foam board heated and mixed with polystyrene resin and polymer, and then extruded continuous rigid foam tank.

從施工工藝上看，外墻巖棉復合板：屬于甲級耐火保溫板，耐火等級高，但保溫效果相對較差，且由于容量大的缺陷，施工難度較大。價格和擠塑板一樣，差別不大。擠塑板：無A級耐火等級，高耐火等級為B1級，火災窒息。因此，外墻巖棉板不屬于擠壓板。如果從各個方面進行比較，在選擇外墻裝飾材料時，可以毫不猶豫地選擇外墻巖棉板。

From the perspective of construction technology, rock wool composite board of external wall belongs to class a fire-resistant insulation board with high fire resistance grade, but its insulation effect is relatively poor, and due to the defects of large capacity, the construction is difficult. The price is the same as extruded board, the difference is not big. Extruded board: no A-class fire resistance rating, the highest fire-resistant grade is B1, and the fire suffocation. Therefore, the outer wall rock wool board does not belong to Extrusion board. If we compare from all aspects, we can choose rock wool board without hesitation when choosing exterior wall decoration materials.
