摘要： Through three separate passages opening in a common plane at right angles to one another into a mixing chamber, three components of a reactant polyurethane or polyurea elastomer composition to form in a mold cavity are introduced. One of the components is an aliphatic polyether amine having primary amino function and substantially free from free hydroxyl groups, catalysts with tertiary amino groups, carbon dioxide as a carbamate reactive with the polyether amine and optionally other inert gases and conventional polyurea additives. The second component is a polyisocyanate or prepolymer thereof and the third component C is water. The reacting mixture is formed through a throttle gap into the mold to form low-density foamed products under low fuming conditions and has no unreacted diisocyanates.

摘要： An impingement mixing device is provided comprising a mixing chamber housing, a control piston axially displaceable with said mixing chamber housing between an extended position and a retracted position, a mixing chamber within the housing defined by an end face of the control piston when in the retracted position and a mixing chamber discharge outlet coextensive with an end face of said control piston when in the extended position, means to feed first and second components to the mixing chamber in opposing relationship, a discharge tube housing defining a quieting chamber having an opening at a discharge end and in fluid communication with the mixing chamber, with said discharge tube housing including a sealing means adapted to at least partially close the opening of the quieting chamber at the discharge end.

摘要： An impingement mixing device is provided comprising a mixing chamber housing, a control piston axially displaceable within said mixing chamber housing between an extended position and a retracted position, a mixture chamber within the housing defined by an end face of the control piston when in the retracted position and a mixing chamber discharge outlet coextensive with an end face of said control piston when in the extracted position, means to feed first and second components to the mixing chamber in opposing relationship, a discharge tube housing defining a quieting chamber having an opening at a discharge end and in fluid communication with the mixing chamber, with said discharge tube housing including a sealing means adapted to at least partially close the opening of the quieting chamber at the discharge end.
