巖棉板與玻璃棉板技術數(shù)據(jù)對比事項

發(fā)布時間:2023-07-24 來源:http://m.95fjrc.com/

生產(chǎn)工藝:巖棉板的生產(chǎn)工藝產(chǎn)用國際上的擺錘法三維立體交織而成,而玻璃棉無法采用此施工工藝,只能采用平織法生產(chǎn)。所其強度不法滿足上墻的要求。
Production process: the production process of rock wool board is three-dimensional interwoven with the internationally advanced pendulum method, while Glass wool cannot use this construction process, and can only be produced by plain weaving. Its strength illegally meets the requirements for climbing on the wall.
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)越高對板的強度,耐高溫,耐久性等性能有顯著的提高。
Acid dissociation constant: Acid dissociation constant of rock wool board ≥ 1.6, Acid dissociation constant of Glass wool ≤ 1.6. The higher the Acid dissociation constant is, the better the strength, high temperature resistance and durability of the board will be.
強度要求:作為可以用于上墻的A級材料(棉制品),所要滿足兩方面強度的要求,1)是壓縮強度需≥40Kpa,2)垂直于板面的拉伸強度需≥7.5Kpa。玻璃棉的這兩個指標為0。
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.
尺寸穩(wěn)定:巖棉板的尺寸穩(wěn)定性相對比較穩(wěn)定為≤1%,而玻璃棉的尺寸穩(wěn)定性在≥8%。尺寸穩(wěn)定性對保溫系統(tǒng)有著至關重要的影響,尺寸穩(wěn)定性差,容易使保溫板膨脹或收縮,導致飾面層破壞,影響保溫系統(tǒng)。

5. 施工方面:巖棉板所采用的是粘釘結合的方式,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行抹灰,故只能進行錨固形式固定,而玻璃棉沒有壓縮強度,所以板子本身相對較軟,在錨固施工時很難施工。其安全性也相對降低。巖棉板施工容易,平整度能有效控制,玻璃棉無法保證其平整度。

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 Construction: The rock wool board adopts the method of bonding nails, which greatly ensures the safety of the rock wool board. Because Glass wool cannot be plastered, it can only be fixed by anchoring. Glass wool has no compressive strength, so the board itself is relatively soft, and it is difficult to construct during anchoring construction. Its safety is also relatively reduced. The construction of rock wool board is easy, the flatness can be effectively controlled, and Glass wool cannot guarantee its flatness.

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級防火材料,但兩者在工作溫度上的差別還是相當明顯的。
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 them is quite obvious.
耐火時間:巖棉板耐火時間為4h;玻璃棉的耐火時間為0.5h。
Fire resistance time: The fire resistance time of rock wool board is 4 hours; The fire resistance time of Glass wool is 0.5h.
導熱系數(shù):巖棉板的導熱系數(shù)為≤0.040(W/m·k)(政府規(guī)定),目前實際導熱系數(shù)能做到0.036(W/m·k)~0.037(W/m·k)。與玻璃棉的0.035(W/m·k)的導熱系數(shù)基本差不多。

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 the same as 0.035 (W/m · k) of Glass wool

9. 干密度:相對于巖棉板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。
9. Dry density: relative to rock wool board 140-160kg/m? Dry density of Glass wool, 10~16kg/m? It is much lighter, which is a major advantage of Glass wool.
