在判斷一款材料是不是能夠防范火災(zāi)時(shí)還有一個(gè)重要的指標(biāo)，它就是熱荷重收縮溫度，這一指標(biāo)常常被用來表示巖棉板的耐濕熱穩(wěn)定性能，測(cè)試熱荷重收縮溫度的方法是可以將濕透的巖棉板浸泡在逐漸加熱的水中，經(jīng)過測(cè)試可以得知，巖棉板的荷重收縮溫度為643度。這也就意味著，當(dāng)外界的溫度達(dá)到643度時(shí)巖棉板才會(huì)變形，而這一溫度遠(yuǎn)遠(yuǎn)高于火災(zāi)發(fā)生時(shí)的溫度，因此使用洛科威多功能巖棉板可以形成安全的防線，即使真的發(fā)生可火災(zāi)，這種材料的耐高溫性能，也可以為消防救援爭(zhēng)取到更多的時(shí)間。

When determining whether a material can prevent fires, there is another important indicator, which is the thermal load shrinkage temperature. This indicator is often used to indicate the moisture and heat resistance stability of rock wool boards. The method of testing the thermal load shrinkage temperature is to immerse the soaked rock wool board in gradually heated water. After testing, it can be determined that the load shrinkage temperature of the rock wool board is 643 degrees. This also means that the rock wool board will only deform when the external temperature reaches 643 degrees, which is much higher than the temperature at the time of the fire. Therefore, using Rockwell multifunctional rock wool board can form a safe line of defense. Even if a fire occurs, the excellent high-temperature resistance of this material can also buy more time for fire rescue.

市面上的巖棉板不在少數(shù)，它們之間的品質(zhì)有所差別。巖棉板這種材料可廣泛應(yīng)用于保溫、隔音、防潮、防火等各個(gè)領(lǐng)域，具有多元化的用途，且它的重量較輕，便于施工，是一種優(yōu)勢(shì)非常明顯的防火保溫材料。

There are many rock wool board brands on the market, and there are differences in quality between them. Rock wool board is a material that can be widely used in various fields such as insulation, sound insulation, moisture-proof, and fire prevention. It has diverse applications, and its weight is light, making it easy to construct. It is a very obvious advantage in fire insulation materials.

理想的保溫材料要具備兩大特點(diǎn)，一是能夠很好地與外界環(huán)境進(jìn)行隔絕，使外界氣流難以進(jìn)入室內(nèi)，其次是材料的熱傳導(dǎo)性能比較差。在建筑裝飾行業(yè)，保溫材料的原理就是，材料中有非常多的密閉小孔，空氣或惰性氣體對(duì)熱量產(chǎn)生慢導(dǎo)性，這樣一來材料就不易產(chǎn)生熱傳導(dǎo)，從而達(dá)到比較好的保溫效果。

An ideal insulation material should have two main characteristics: firstly, it can be well isolated from the external environment, making it difficult for external airflow to enter the room, and secondly, the thermal conductivity of the material is relatively poor. In the construction and decoration industry, the principle of insulation materials is that there are many sealed small holes in the material, and air or inert gas has a slow conductivity to heat. This makes the material less prone to heat conduction, thus achieving better insulation effects.

巖棉板是符合上述條件的防火保溫材料，這種材料的利用導(dǎo)熱系數(shù)的變化與纖維的直徑、方向排列以及產(chǎn)品的密度均有關(guān)的特性，通過纖維的不規(guī)則排列和分布將空間分割成多個(gè)密閉小空間，小空間的體積越大則保溫效果越好。當(dāng)巖棉板采用了更細(xì)、更長(zhǎng)的纖維，巖棉尺寸一定時(shí)，可分割出更多的空間，從而具有更低的導(dǎo)熱系數(shù)，可達(dá)到更好的保溫效果。

Rock wool board is a fireproof and thermal insulation material that meets the above conditions. The variation in thermal conductivity of this material is related to the diameter, direction arrangement, and product density of the fibers. Through the irregular arrangement and distribution of fibers, the space is divided into multiple enclosed small spaces. The larger the volume of the small space, the better the insulation effect. When the rock wool board uses finer and longer fibers and the size of the rock wool is fixed, more space can be divided, resulting in lower thermal conductivity and better insulation effect.
