Methods for producing fire retardant cellulosic products

摘要: Fire retardant compositions in pelletized and aqueous solution form constituting mixtures containing a ratio by weight about 30-50% monoammonium phosphate 70-50% diammonium phosphate, optionally corrosion inhibitor, which are of substantially neutral pH contain 10-part 3-7.9 parts total 7-2.1 water, surfactant; methods using such for providing composite fire cellulosic products the is intimately intermixed with fiber material to loose fibers thereof absorbed therein, e.g. 100-part 6-16 94-84 having bulk density corresponding settled 2.0-3.1 lbs/ft 3 , addition finely divided solid supplemental also distributed thereon, solution, 1-9 93-75 material; produced thereby.
