巖棉板與玻璃纖維棉的區(qū)別

發(fā)布時間:2023-04-04 來源:http://m.95fjrc.com/

巖棉板又稱巖棉保溫裝飾板,是以玄武巖為主要原材料,經(jīng)高溫熔融加工而成的無機纖維板,是一種新型的保溫、隔燃、吸聲材料。目前做隔音用玻璃棉比較多。那么濟南巖棉板與玻璃纖維棉的區(qū)別是怎樣的呢?
Rock wool board, also known as rock wool insulation decorative board, is an inorganic fiber board made from basalt as the main raw material and processed by high-temperature melting. It is a new type of insulation, flame insulation, and sound absorption material. Currently, there are many glass wool materials used for sound insulation. So what is the difference between Jinan rock wool board and glass fiber cotton?
1.巖棉是礦渣為原料,玻璃纖維棉是精礦為原料(石英石礦);
1. Rock wool is made from slag, while glass fiber wool is made from concentrate (quartz ore);
2.巖棉的纖維絲較粗較短(巖棉需要更高的密度、更厚些才能成形),玻璃纖維棉纖維絲更細(xì)更長,所以相同密度的情況下玻璃纖維棉會更結(jié)實,結(jié)構(gòu)會更錯綜復(fù)雜,因此玻璃纖維棉的吸音系數(shù)會更高;
2. The fiber fibers of rock wool are thicker and shorter (rock wool requires higher density and thicker to form), while the fiber fibers of glass fiber cotton are thinner and longer. Therefore, under the same density, glass fiber cotton will be stronger and its structure will be more complex, resulting in a higher sound absorption coefficient of glass fiber cotton;
3.巖棉的纖維絲比較粗比較短,在成板是沒那么結(jié)實,容易出現(xiàn)松散的現(xiàn)象,特別是在密度低于100KG的情況下,如果填充在隔墻內(nèi),容易出現(xiàn)松垮的現(xiàn)象,時間久了棉就會往下垮成一跎,失去剛開始安裝好時的隔音效果,而玻璃纖維棉密度超過32KG時就不會出現(xiàn)這種情況;
3. The fiber fibers of rock wool are relatively thick and short, which are not as strong as the finished board and are prone to loosening, especially when the density is less than 100KG. If filled in the partition wall, it is easy to collapse. Over time, the cotton will collapse and lose its sound insulation effect when it was first installed. However, this situation does not occur when the density of glass fiber cotton exceeds 32KG;
4.相同密度、厚度的情況下,剛安裝好時,玻璃纖維棉的吸音、隔音效果,大概是巖棉的1.2倍左右;
At the same density and thickness, when first installed, the sound absorption and soundproofing effect of glass fiber cotton is about 1.2 times that of rock wool;

5.二種材料同為A級防火材料,都是纖維絲制品,碰到人身上會癢,都不環(huán)保的,巖棉相對會更癢;
5. Both materials are A-grade fireproof materials, both of which are fiber silk products. They will itch when they come into contact with people and are not environmentally friendly. Rock wool will relatively itch more;
6.巖棉耐高溫大概500度,玻璃纖維棉耐高溫大概200度,二種材料的導(dǎo)熱系數(shù)相當(dāng),巖棉現(xiàn)多應(yīng)用于保溫隔熱方面,玻璃纖維棉現(xiàn)多應(yīng)用于吸音隔音方面。
6. Rock wool has a high temperature resistance of about 500 degrees Celsius, and glass fiber cotton has a high temperature resistance of about 200 degrees Celsius. The thermal conductivity of the two materials is equivalent. Rock wool is now mostly used for insulation and insulation, while glass fiber cotton is now mostly used for sound absorption and sound insulation.
巖棉板除了保溫隔熱還能隔音降噪。巖棉的吸音效果不能光看厚度,還要看巖棉的容重還有表面是否有吸引沖孔,做隔音墻必須采用幾種不同性質(zhì)的材料,比如在承重的磚墻前加隔音材料,按防火要求,采用100毫米厚的巖棉,封閉后再用柔性面料裝飾即可達到要求。你有需求可以隨時來我們網(wǎng)站http://m.95fjrc.com咨詢!
Rock wool board not only provides insulation and insulation, but also provides sound insulation and noise reduction. The sound absorption effect of rock wool cannot be solely determined by its thickness, but also by its bulk density and whether there are attractive punching holes on the surface. Several different materials must be used for soundproofing walls, such as adding soundproofing materials in front of load-bearing brick walls, using 100mm thick rock wool according to fire protection requirements, and decorating with flexible fabrics after sealing can meet the requirements.
