AI Technical Summary

Problems solved by technology

In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic thermal insulation materials need to be assembled and constructed, there are many seams, which damage the appearance and waterproof. Defects such as poor performance and short service life
