Could any expert tell me more about pearlescent sand – its functions, areas of application, and so on? The more information, the better. I need to create a PPT, but I’m having trouble finding enough relevant materials :(
1. Online search. 2. Contact the manufacturer for technical information. 3. Relevant standards can be referred to; pearlescent sand is likely to be a type of perlite material. Expanded perlite, as one component of the insulation coating layer used in insulation work, can be found in Appendix B of the \"SHT3522-2003 Standards for Construction Techniques in Petrochemical Insulation Projects\". In addition, other standards also cover \"JC/T 209-2012 Expansive Perlite\", \"SDJ 68—85 Technical Requirements and Inspection Methods for Insulation Materials Used in Thermal Equipment and Pipelines in Thermal Power Plants\", \"GBT 4132-1996 Insulation Materials and Related Terms\", \"GB/T 4272-2008 General Principles for Insulation Techniques in Equipment and Pipelines\", \"GB 50126-2008 Construction Specifications for Insulation Works of Industrial Equipment and Pipelines\", \"GB 50185-2010 Quality Acceptance Specifications for Construction of Insulation Works of Industrial Equipment and Pipelines\", and \"GB 50264-2013 Design Specifications for Insulation Works of Industrial Equipment and Pipelines\"
Pearl sand is a white, granular, loose material with a porous structure, produced by crushing, preheating, and calcining acidic volcanic glassy lava. It possesses characteristics such as low density, low thermal conductivity, good chemical stability, non-flammability, non-toxicity, odorlessness, and sound absorption. Primarily used in cold boxes for insulation; properties of pearlescent sand: http://bbs.hcbbs.com/thread-242156-1-1.html (Source: Haichuan Chemical Industry Forum)
The pearlescent sand I know is used in cold boxes; I hope it’s useful to you
It provides insulation against heat loss and is used as a filler in cryogenic equipment such as air separation units.
Here, our pearlescent sand is mainly used in cold boxes
