岩棉板和挤压板有什么区别

发布时间:2020-12-02 来源:http://www.jnhxtcg.com/

很多时候外墙岩棉板和挤压板分不清,外墙岩棉板是挤压板吗?下面就一起来看看。外墙岩棉板以优质玄武岩和白云石为原料,将外墙岩棉板系列产品在1450℃下熔融,制成各种硬度的岩棉制品。岩棉板广泛应用于有保温、防火、隔音要求的场所。

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.

岩棉纤维由于其纤细、柔韧的结构,具有抗压强度高、抗拉强度高等特点。挤塑板是以聚苯乙烯树脂为原料,经特殊工艺连续挤塑发泡而成的刚性板,其内部为独立的密闭气泡结构,是一种高抗压、无吸水、防潮、环保的保温材料,气密、重量轻、耐腐蚀、使用寿命长、导热系数低等优良性能。从这两种材料的特点和使用场所来看,似乎都与一系列材料相似。

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.

但从原材料和性能上看,外墙岩棉板属于无机保温材料,是以铁渣为主要原料,经高压蒸汽喷射熔化冷却而成。是一种用聚苯乙烯树脂和聚合物加热并混合成催化剂的硬质泡沫板,然后挤出连续的硬质泡沫槽。

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.

从施工工艺上看,外墙岩棉复合板:属于甲级耐火保温板,耐火等级高,但保温效果相对较差,且由于容量大的缺陷,施工难度较大。价格和挤塑板一样,差别不大。挤塑板:无A级耐火等级,最高耐火等级为B1级,火灾窒息。因此,外墙岩棉板不属于挤压板。如果从各个方面进行比较,在选择外墙装饰材料时,可以毫不犹豫地选择外墙岩棉板。

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.
