Thermal insulation test:
Two brick concrete structure houses and light steel structure houses
with the same size and thickness were made respectively, and they were
tested in a professional laboratory to see how much the temperature
difference between them was?
保溫箱里的溫度將持續下形骨架模具 保定代理記賬 保定道閘 防撞護欄模具 風電基礎模具 保定空壓機 北京真空泵降到零下30℃，實驗顯示在降溫過程中，輕鋼結構里面的溫度和磚混空間里面的溫度差一直保持在13℃左右。
The temperature in the incubator will continue to drop to minus 30 ℃.
The experiment shows that during the cooling process, the temperature
difference between the light steel structure and the brick concrete
space has been maintained at about 13 ℃
