A METHOD OF PRODUCING A NON-WOVEN MINERAL FIBER WEB, A PLANT FOR PRODUCING A NON-WOVEN MINERAL FIBER WEB, AND A MINERAL FIBER PRODUCT

摘要

In a method of producing a non-woven mineral fiber web, mineral fibers are produced from a mineral material by means of a mineralfiber generating means. The mineral fibers are transferred from the mineral fiber generating means by means of a carrier air stream,and droplets and or particles of a bonding agent or coupling agent is introduced into the carrier air stream for causing the mineral fibersto be bonded or linked together. In order to eliminate waste of bonding agent or coupling agent material, the droplets and/or particlespredominantly have diameters larger than a minimum diameter corresponding to a droplet and/or particle showing substantially no tendencyto impact the mineral fibers of the carrier air stream.
