求翻译：普通膨胀珍珠岩颗粒内部孔隙率高、密度小，但作为保温砂浆骨料使用时存在吸水率高的缺陷，吸水率根据其密度的大小可达自身重量的4倍以上，而水的导热系数比空气大24倍，吸水后的膨胀珍珠岩内部由水构成了众多的热桥，使由膨胀珍珠岩作轻骨料的保温砂浆的导热系数大幅提高，保温性能显著下降。是什么意思？

Expanded perlite particles within the ordinary high porosity, low density, but when used as thermal insulation there is high water absorption of aggregate defects, their density, water absorption according to the size of up to four times its own weight, and thermal conductivity than water big air 24

Ordinary expanding perlite particles internal porosity, density, but as high thermal insulation mortar galvanizer exist when using the high rate of water absorption rate of water absorption, deficiencies in accordance with its density of size can be up to its own weight in water, and more than four

The ordinary inflated pearlite pellet interior factor of porosity high, the density is small, but took when heat preservation mortar aggregate use has the water-absorptivity high flaw, the water-absorptivity acts according to its density the size to be possible to reach own weight above 4 times, but

General expansion Pearl rock particles internal pore rate high, and density small, but as insulation mortar aggregate using Shi exists suction water rate high of defects, suction water rate under its density of size may up itself weight of 4 times times above, and water of thermal conductivity coeff
