Abstract

An asbestos-cement additive comprises loose asbestos fibres having a hydromodifier substantially completely adsorbed thereon. The additive may be produced by mixing asbestos fibres and hydromodifier, e.g. while the asbestos is suspended in air, moving the mixture, e.g. by means of an air jet, adding atomized water droplets to the moving mixture, and drying. The term hydromodifier, which is defined in Specification 992,427, includes methyl cellulose, hydroxypropoxy methyl cellulose, carboxy methyl hydroxy ethyl cellulose, hydroxy ethyl cellulose ether, carboxy methyl starch ether, ethylene oxide polymer, acrylamide polymer, partially hydrolyzed polyacrylamide, Na salt acrylamide acrylic acid copolymer, polyvinyl alcohol, casein, and hide glue, singly, mixed or mixed with non-hydromodifiers. The hydromodifier may form up to 12% wt. of the mixture.ALSO:An asbestos-cement additive comprises loose asbestos fibres having a hydromodifier substantially completely adsorbed thereon.
