| 摘要:研究了温度、多孔填料及填料的添加比例对6种不同打浆度玻璃棉纤维纸导热系数的影响。结果表明,在-10～20℃之间,随着温度的升高, BM-1和BM-3纤维纸对应的导热系数变化不大,当温度由-10℃升高到0℃时,BM-2纤维纸的导热系数由0.0182 W/m·K增加到0.0287 W/m·K,增加了57.7%,变化非常明显,而BM-4、BM-5、BM-6纤维纸的导热系数也分别增加了30.4%、40.6%、32.4%。添加200～400目膨胀珍珠岩的玻璃棉纤维纸导热系数比蛭石的小,且二者的添加比例为30%时,其成纸的导热系数最低。填料的目数对其成纸的导热系数影响变化不大。 |
| Abstract:The influences of temperature, usage of porous filler and the dosage of filler on the thermal conductivity of micro-fiber glass wool paper were studied. The results showed that the thermal conductivity of BM-1 and BM-3 papers changed little between -10～20℃ as the temperature increased, when the temperature increased from -10℃ to 0℃,the thermal conductivity of the BM-2 paper increased from 0.0182 W/ (m·K) to 0.0287W / (m·K) with an increase of 57.7%, the change was very obvious; while the thermal conductivity of the papers BM-4, BM-5, BM-6 also increased by 30.4%, 40.6%, 32.4%. The thermal conductivity of micro fiber glass wool paper adding 200 to 400 mesh expanded perlite was smaller than that adding vermiculite, and the thermal conductivity of the paper was the minimum when the filler dosage was 30%.The filler particle size had little influence on the thermal conductivity of the paper. |
