METHOD AND COMPOSITION FOR DUST CONTROL

摘要

The invention is directed towards methods and compositions for treating piles of particulate materials to inhibit and prevent the loss of valuable fuel or mineral dust from being released from storage piles or open containers. The method involves applying separately to the pile two different compositions. When separate the two compositions are low viscosity and easy to spray. When combined the two form a gel coating that is resistant to erosion but is flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around. This coating is especially effective for coal piles, iron ore piles, and also for piles within and/or being moved by open topped railroad cars. The coating's flexibility prevents the coating from becoming brittle and shattering. The coating has better performance than its ingredients do alone. As a result the invention can both prevent unwanted dust pollution as well as save its users money by avoiding loss of blown away material.

主权项

1. A method of inhibiting the release of dust from a pile of particulate material, the method comprising the step of applying to the exposed surface of the pile a binder composition, the binder composition comprising a first composition and a second composition, each of the first and second composition having a viscosity of less than 100 cP when apart, but when mixed together they have a viscosity of more than 10,000 cP.
