油田中转站、联合站的“三合一”、“四合一”容器通常采用蛭石保温。大庆油建施工技术研究所利用大庆地区珍珠岩原料充足的条件,进行了水玻璃膨胀珍珠岩保温块代替蛭石砖的试验。结果表明,在强度和保温性能等方面,水玻璃珍珠岩制品均优于蛭石砖(表1)。
The three-in-one and four-in-one containers in oilfield transfer stations and coal stations are usually insulated with vermiculite. Daqing Oil Construction Technology Research Institute used the sufficient conditions for the perlite of Daqing area to carry out the test of water glass expanded perlite insulation blocks instead of gangue bricks. The results show that the water glass pearlite products are superior to the gangue bricks in terms of strength and thermal insulation properties (Table 1).
