Are there any insulation materials with a lower thermal conductivity than rock wool that offer better insulation performance?
Silicate and polyurethane materials, for example, offer better performance than rock wool; I’m not sure what kind of ring you want to insulate – rock wool is flammable
But according to the design manual, the thermal conductivity of silicates is higher than that of rock wool; then why is it said that silicates provide better insulation?
Chemical Process Design Manual P81
The poster can refer to the SH/T3010-2013 Design Code for Insulation of Petrochemical Equipment and Piping; aluminum silicate based on silicate materials offers good performance, but at a higher cost
Okay, thank you very much. . . . .
High-temperature glass wool. . . . .
In China, the reputation of rock wool has been damaged by materials like slag wool; in fact, proper rock wool is by no means inferior. As you can see, aluminum silicate cotton can be used at high temperatures, but its drawback is its high thermal conductivity. So if both materials are of qualified quality and the temperature is within the range suitable for rock wool use, in fact rock wool will require a thinner insulation layer. As far as I know, the European market is dominated by rock wool, but the rock wool used there is not exactly the same as the \"rock wool\" used in China. Therefore, for high-temperature applications, it’s better to use aluminum silicate wool in China, while centrifugal glass wool can be used at temperatures below 300°C.
The thermal insulation effect of aerogels is much better than that of rock wool, provided it is genuine aerogels
It should be available; the price might be high. Rock wool seems to be a good option in terms of cost-performance, as it also offers decent insulation properties. Our company uses rock wool for all its insulated pipelines
Is there a lot of broken centrifugal glass wool, and will it be as irritating as rock wool?
