外墻保溫巖棉板的防火保溫性能

1、絕熱性能:絕熱性能好是巖棉板巖棉、礦渣棉制品的基本特性,,在常溫條件下(25℃左右)巖棉的熱導(dǎo)率通常在0.03~0.047W(moK)之間.

1. Insulation performance: Good insulation performance is a basic characteristic of rock wool board, rock wool, and slag wool products. Under normal temperature conditions (around 25 ℃), the thermal conductivity of rock wool is usually between 0.03 and 0.047W (moK)

2、燃燒性能:巖棉板巖棉、礦渣棉制品的燃燒性能取決于其中可燃性粘接劑的多少。巖棉、礦渣棉本身屬無機(jī)質(zhì)礦物纖維,不可燃,在加工成制品的過程中,有時(shí)要加入有機(jī)粘結(jié)劑或添加物,這些對(duì)制品的燃燒性能會(huì)產(chǎn)生一定的影響。

2. Combustion performance: The combustion performance of rock wool board, rock wool, and slag wool products depends on the amount of combustible adhesive used. Rock wool and slag wool are inorganic mineral fibers that are not flammable. In the process of processing into products, organic binders or additives are sometimes added, which can have a certain impact on the combustion performance of the products.

3、隔音性能:巖棉板巖棉、礦渣棉制品具有優(yōu)良的隔音和吸聲性能,其吸聲機(jī)理是這種制品具有多孔性結(jié)構(gòu),當(dāng)聲波通過時(shí),由于流阻的作用產(chǎn)生摩擦,使聲能的—部分為纖維所吸收,陰礙了聲波的傳遞。

3. Sound insulation performance: Rock wool board, rock wool, and slag wool products have excellent sound insulation and absorption performance. The sound absorption mechanism is that these products have a porous structure. When sound waves pass through, friction is generated due to the effect of flow resistance, causing some of the sound energy to be absorbed by fibers, which hinders the transmission of sound waves.

4、吸音降噪施可達(dá)巖棉是理想的隔音材料,大量的細(xì)長纖維形成了多孔連接結(jié)構(gòu),決定了施可達(dá)巖棉是一種出色的吸音降噪料。

4. Sound absorption and noise reduction: Shida rock wool is an ideal sound insulation material. A large number of slender fibers form a porous connection structure, which determines that Shida rock wool is an excellent sound absorption and noise reduction material.

5、憎水性施可達(dá)憎水巖棉產(chǎn)品憎水率可達(dá)到99.9%;吸水率極低,無毛細(xì)滲透。

5. The hydrophobicity of water repellent rock wool products can reach 99.9%; Extremely low water absorption and no capillary penetration.

6、抗潮性能施可達(dá)巖棉在相對(duì)濕度很大的環(huán)境下,體積吸濕率小于0.2%;按ASTMC1104或ASTM1104M方法測試,質(zhì)量吸濕率小于0.3%。

6. The moisture resistance of rock wool can be achieved by applying it. In environments with high relative humidity, the volumetric moisture absorption rate is less than 0.2%; According to the ASTMC1104 or ASTM1104M method, the mass moisture absorption rate is less than 0.3%.

7、無腐蝕性施可達(dá)巖棉化學(xué)性質(zhì)穩(wěn),PH值為7—8,呈中性或弱堿性,對(duì)碳鋼、不銹鋼、巖棉復(fù)合板的飾面板是采用高強(qiáng)耐候的水泥纖維板作為防護(hù)層。標(biāo)準(zhǔn)密度g/cm31.4。

7. Non corrosive application can achieve stable chemical properties of rock wool, with a pH value of 7-8, neutral or weakly alkaline. For the decorative panels of carbon steel, stainless steel, and rock wool composite boards, high-strength and weather resistant cement fiber boards are used as protective layers. Standard density g/cm 31.4.
