濟(jì)南巖棉板與玻璃棉板技術(shù)數(shù)據(jù)對(duì)比

發(fā)布時(shí)間:2023-04-26 來(lái)源:http://m.95fjrc.com/

1. 生產(chǎn)工藝:巖棉板的生產(chǎn)工藝產(chǎn)用國(guó)際上的擺錘法三維立體交織而成,而玻璃棉無(wú)法采用此施工工藝,只能采用平織法生產(chǎn)。所其強(qiáng)度不法滿(mǎn)足上墻的要求。
1. Production process: The production process of rock wool board is made using the internationally advanced pendulum method of three-dimensional interweaving, while glass wool cannot use this construction process and can only be produced using the flat weaving method. Its strength illegally meets the requirements for climbing on the wall.
2. 酸度系數(shù):巖棉板的酸度系數(shù)≥1.6,玻璃棉的酸度系數(shù)≤1.6。而酸度系數(shù)越高對(duì)板的強(qiáng)度,耐高溫,耐久性等性能有顯著的提高。
2. Acidity coefficient: The acidity coefficient of rock wool board is ≥ 1.6, and the acidity coefficient of glass wool is ≤ 1.6. The higher the acidity coefficient, the greater the strength, high temperature resistance, and durability of the board.
3. 強(qiáng)度要求:作為可以用于上墻的A級(jí)材料(棉制品),所要滿(mǎn)足兩方面強(qiáng)度的要求,1)是壓縮強(qiáng)度需≥40Kpa,2)垂直于板面的拉伸強(qiáng)度需≥7.5Kpa。玻璃棉的這兩個(gè)指標(biāo)為0。
3. Strength requirements: As an A-grade material (cotton product) that can be used for wall mounting, it must meet two strength requirements: 1) the compressive strength must be ≥ 40Kpa, and 2) the tensile strength perpendicular to the board surface must be ≥ 7.5Kpa. These two indicators of glass wool are 0.
4. 尺寸穩(wěn)定:巖棉板的尺寸穩(wěn)定性相對(duì)比較穩(wěn)定為≤1%,而玻璃棉的尺寸穩(wěn)定性在≥8%。尺寸穩(wěn)定性對(duì)保溫系統(tǒng)有著至關(guān)重要的影響,尺寸穩(wěn)定性差,容易使保溫板膨脹或收縮,導(dǎo)致飾面層破壞,影響保溫系統(tǒng)。

4. Dimensional stability: The dimensional stability of rock wool board is relatively stable at ≤ 1%, while the dimensional stability of glass wool is ≥ 8%. Dimensional stability has a crucial impact on the insulation system. Poor dimensional stability can easily cause expansion or contraction of the insulation board, leading to damage to the decorative layer and affecting the insulation system.
5. 施工方面:巖棉板所采用的是粘釘結(jié)合的方式,此方式大大保證的巖棉板的安全性,而玻璃棉由于其特性不能進(jìn)行抹灰,故只能進(jìn)行錨固形式固定,而玻璃棉沒(méi)有壓縮強(qiáng)度,所以板子本身相對(duì)較軟,在錨固施工時(shí)很難施工。其安全性也相對(duì)降低。巖棉板施工容易,平整度能有效控制,玻璃棉無(wú)法保證其平整度。
5. Construction: The rock wool board adopts a bonding method of adhesive nails, which greatly ensures the safety of the rock wool board. However, glass wool cannot be plastered due to its characteristics, so it can only be fixed by anchoring. Glass wool does not have compressive strength, so the board itself is relatively soft, making it difficult to construct during anchoring construction. Its safety is also relatively reduced. The construction of rock wool board is easy, and the flatness can be effectively controlled. Glass wool cannot guarantee its flatness.
6. 工作溫度:巖棉板的工作溫度在≥650℃;玻璃棉的工作溫度在≥250℃,雖然同為A1級(jí)防火材料,但兩者在工作溫度上的差別還是相當(dāng)明顯的。
6. Working temperature: The working temperature of rock wool board is ≥ 650 ℃; The working temperature of glass wool is ≥ 250 ℃, although both are A1 grade fireproof materials, the difference in working temperature between the two is still quite significant.
7. 耐火時(shí)間:巖棉板耐火時(shí)間為4h;玻璃棉的耐火時(shí)間為0.5h。
7. Fire resistance time: The fire resistance time of rock wool board is 4 hours; The fire resistance time of glass wool is 0.5 hours.
8. 導(dǎo)熱系數(shù):巖棉板的導(dǎo)熱系數(shù)為≤0.040(W/m·k)(政府規(guī)定),目前實(shí)際導(dǎo)熱系數(shù)能做到0.036(W/m·k)~0.037(W/m·k)。與玻璃棉的0.035(W/m·k)的導(dǎo)熱系數(shù)基本差不多。
8. Thermal conductivity: The thermal conductivity of rock wool board is ≤ 0.040 (W/m · k) (government regulations), and currently the actual thermal conductivity can reach 0.036 (W/m · k) to 0.037 (W/m · k). The thermal conductivity is basically similar to 0.035 (W/m · k) of glass wool.
9. 干密度:相對(duì)于巖棉板140~160kg/m?的干密度,玻璃棉的10~16kg/m?就輕了很多,這是玻璃棉的一大優(yōu)勢(shì)。
9. Dry density: relative to rock wool board 140-160kg/m? The dry density of glass wool is 10-16kg/m? It's much lighter, which is a major advantage of glass wool.
10. 吸水性:憎水型巖棉板的憎水率為≥99%,吸水率為≤1kg/m?(浸水24h的吸水率),而玻璃棉的吸水率為≥3kg/m?。同時(shí)玻璃棉的尺寸穩(wěn)定性又比巖棉板要差。一旦吸水,很容易膨脹,從而破壞保溫系統(tǒng)。
10. Water absorption: The water absorption rate of hydrophobic rock wool board is ≥ 99%, and the water absorption rate is ≤ 1kg/m? (Water absorption rate after 24 hours of immersion), while the water absorption rate of glass wool is ≥ 3kg/m?. At the same time, the dimensional stability of glass wool is worse than that of rock wool board. Once water is absorbed, it is easy to expand, thereby damaging the insulation system.
