Abstract
Coal and other particulate can be transported on a conveyor belt exposed to winter weather conditions with reduced slippage of the particulate on the belt surface by periodically treating the belt surface with from about 0.001 to about 0.005 gallons per square foot of belt surface (0.04-0.4 liters/sq. meter) of a composition containing a small amount of a dimethyl polysiloxane with the balance consisting substantially of water soluble components comprising (A) a water soluble polyhydroxy compound or monoalkyl ether thereof, and (B) a water soluble organic nonvolatile compound having at least one hydrophilic group, (A) being different from (B).
Claims8
A composition for treating a belt surface consisting essentially of from about 0.05 to about 2% by weight a dimethyl polysiloxane, with the balance consisting essentially of water soluble components
- (A) a water soluble polyhydroxy compound or monoalkyl ether thereof, and, per part by weight of (A),
- (B) from about 0.001 to about 2 parts a water soluble nonvolatile organic compound having at least one hydrophilic group, said compound (B) being different from said compound (A),
- said composition being substantially free of corrosion inducing metal halide salts and said water soluble components contain less than about 5% of water immiscible liquids.
