Jinan rock wool sandwich board is a common material in thermal insulation construction. This product is a combination of rock wool board and sandwich board. It has more outstanding effect in strength, sound insulation and heat preservation performance. It plays an important role in the fields of external wall insulation and roof insulation.
Rock wool sandwich board is made of rock wool. The rock wool sandwich board has made full use of the unique performance of rock wool core material, and has remarkable effect in fire prevention, heat insulation and sound insulation. The disadvantage of rock wool sandwich board is that its strength is not enough, but it is suitable for roof, wall, ceiling, partition wall and simple activity room of steel structure workshop. Steel structure workshop clean room and simple activity room. Rock wool sandwich board can be customized according to customer requirements. It is a kind of sandwich panel with excellent fire resistance on a series of sandwich panels. What is the performance of Jinan rock wool sandwich board
济南岩棉夹芯板的原材料、生产工艺和配方使其具有良好的耐火性。试验表明，其耐火性超过1000℃。岩棉夹心板对降低噪声传递有显著效果，特别适用于有指定航班的地方。此外，采用岩棉屋顶，雨水、冰雹对屋顶建筑钢板的冲击造成室内声响，也明显减弱。根据ISO 717/82和UNI 8270/7标准，选用120kg/m&sup3为密度，岩棉为芯材，隔声效果可达RW=29-30dB。吸音：岩棉夹心板也具有极好的吸音效果，它可以吸收声音内的各种频率。根据ISO 35/85标准，岩棉夹芯板的吸声性能达到ΔLa= 157dB(A)。
Jinan rock wool sandwich board has good fire resistance because of its raw materials, production process and formula. The test results show that the fire resistance is more than 1000 ℃. The results show that the rock wool sandwich panel has a significant effect on reducing the noise transmission, especially suitable for the places with designated flights. In addition, when rock wool roof is used, the impact of rain and hail on the steel plate of roof building will cause indoor sound, which is also significantly reduced. According to ISO 717 / 82 and uni 8270 / 7 standards, when 120kg / M & sup3 is selected as density and rock wool as core material, the sound insulation effect can reach 29-30db. Sound absorption: rock wool sandwich board also has excellent sound absorption effect, it can absorb various frequencies in the sound. According to ISO 35 / 85 standard, the sound absorption performance of rock wool sandwich panel reaches Δ La = 157db (a).
In the whole manufacturing process of rock wool sandwich panel, the surface of partition board is treated by adhesive and rolling, which can better ensure the bonding effect between layers, and effectively improve the corrosion resistance and oxidation resistance of pigment. R-shaped steel fire wall. The high quality rock wool is used in the middle layer, and its insulation performance is also high quality, fine and uniform foam. Its insulation performance and intensity are very good, and the firewall is widely used. The wallboard has the advantages of low friction, no pollution, light weight and convenient installation time. If the construction of buildings with high fire protection requirements, due to the particularity of fire protection requirements, color steel sandwich panel is composed of plastering layer, decorative layer, bonding layer, thermal insulation layer and related accessories. The decorative surface of fireproof partition board is made of high quality decorative mortar, which makes the air permeability of partition board equal. Good.
Jinan rock wool sandwich board specifications generally have two kinds of width: 950mm or 1150 mm, length 16000 mm, thickness generally 50 mm, 75 mm, 100 mm, length can be customized according to user requirements. As we all know, continuous sandwich panel has the advantages of fire protection, heat preservation, heat insulation and sound absorption. But friends also know that it is also scratch resistant, unlike other building materials that are easy to scratch and difficult to repair, rock wool sandwich board. Adhesive free protective film is applied on the production surface, so the installation and transportation of the surface will not be so fragile.
