The bulk density of oil tank insulation cotton is about 150 cubic meters

Several oil tanks of about 150 cubic meters in the unit have their bottoms replaced and repaired, and they need to be re-insulated. The insulation requires both thermal insulation and heat insulation. In this case, what is the important insulation cotton content?
Is the "insulation cotton" mentioned by the poster the aluminum silicate fiber cotton? “The essence of "insulation" is "heat insulation". The insulation performance of the insulation layer is related to the thermal conductivity and thickness of the insulation material. Aluminum silicate fiber varies with production process ； Differences in raw material properties ； Differences in product quality ； There are big differences in their technical parameters. Their test weights also vary greatly. So the key here is the thermal conductivity of the material, not the bulk density. The thermal insulation requirements should be determined according to the working environment of the equipment. ； Choose insulation materials and determine insulation thickness. It is necessary to go through strict calculations.
In fact, I also heard from friends in the thermal insulation industry that if good thermal insulation is required, use aluminum silicate. The problem is that I chose rock wool. The bulk density of rock wool is not too high for thermal insulation, but I didn’t say how much specific it is, so I posted this post. Listening to everyone’s opinions, if it is purely thermal insulation, I would know to use aluminum silicate plus fiberglass sheath. The problem is that both thermal insulation and thermal insulation are required, and the rock wool powdered lime cement is not that strong, cracks severely, and the use time is not long.
