Patent PT-75183-A (PT)
IPC: B24C1/00
Filed: 1982-07-05
Abstract: For sand blasting a stream of a suspension of a carrier gas and solid particles under superatmospheric pressure is restricted so that it is accelerated, and a liquid-carrying additive gas is mixed with the stream to moisten the particles. The additive gas is introduced into the stream at a pressure greater than the pressure of the stream at the location by between 1.5 and 2.5 times. Normally the additive-gas pressure is about twice the carrier-gas pressure, that is the additive gas is normally introduced at a pressure of between about 10 bar and 30 bar. This high-pressure introduction ensures that the additive gas enters well into the carrier-gas stream so that the liquid carried by the additive gas contacts and wets the solids carried by the carrier gas without just passing through it and wetting the inside of the sand-blast mix nozzle. The additive gas is introduced into the stream in a unit of time at a rate sufficient to introduce into the stream a quantity of the liquid equal to between about one-twentieth to one-thirtieth, preferably one-twenty-fifth, the mass of the particles passing the location during the unit of time.

Title: Multi-component coating compositions
IPC: C09D133/00
Filed: 1985-08-27
Abstract: This invention relates to aqueous "multi-pack" coating compositions, that is, those which comprise at least two discrete components (or "packs") which are mixed prior to application. Prior attempts to provide an aqueous multi-pack composition have failed to provide a suitable combination of the desirable characteristics of adequate "pot-life" (the time for which the mixed components remain workable) and early development of adequate mechanical properties. The compositions of the present invention which provide such a combination consist of a number of components which together comprise a constituent having epoxide groups, a constituent comprising addition polymer in the form of an aqueous dispersion and a constituent capable of reacting with epoxide groups. In an especially preferred embodiment, the aqueous addition polymer dispersion is combined with at least one of the other constituets in the form of a multi-polymer particle dispersion. The compositions are useful in the automotive refinish and heavy duty coatings areas.
