The Integration of New Technology Research on Composite Inorganic Fiber Acoustic Insulation Spray in Engineering Construction

Abstract

Composite inorganic fiber spray technology was based on high-strength interfacial agent, then sprayed an appropriate mixed proportion of ultrafine diameter (D <4μm) composite inorganic fibers, adhesives, cement and other raw materials through a dedicated spray equipment on the building roof (ceiling) or flank, which formed a homogeneous, porous, durable and eco-friendly cover layer. The key technology is combined composite inorganic fiber sprays’ adhesive, mixing, porous, insulation and acoustic fireproof mechanism with three key technology working principles " high-strength interfacial agent sector coverage ", " composite inorganic fibers + adhesive multiple mixed spray " and " continuous overall seamless fireproof insulating layer ", to achieve integrate engineering effects of insulation, fastness, energy-efficient, sound-absorbing and homogeneous coverage. The new technology solves acoustic insulation problems of public buildings with fireproof requirements as: underground garage ceiling, elevator shafts and fire passage, etc.
