Hardun KKQ Perlite expansion and vitrification furnace was invented and successfully developed by our factory director and senior engineer Kong KeQiang in February 2003. In 2005, he was granted a national invention patent for the furnace. This is the world's first industrial production equipment dedicated to the production of closed-cell vitrified expanded perlite microbeads. Different from the open-hole perlite products produced by traditional perlite expansion furnace, the perlite produced by our perlite expansion furnace production line is in the form of closed-cell vitrified microbeads, which greatly enhances and expands the use function and scope of perlite, is a historic breakthrough in green new materials, and greatly improves the new industrial value of perlite. In particular, the application of external wall insulation materials has made great contributions to the sustainable development of social green, environmental protection and energy saving. It is a great invention of new environmentally friendly materials in this century. In the past 20 years, 80% of the perlite vitrified expanded microspheres used for wall insulation mortar at local and abroad are produced by our perlite expansion and vitrification furnace.
