ABSTRACT:
A static mixing chamber for mixing multi-component compositions has the provision of having the mixing chamber at the outlet of the feed lines. A valve is at the outlet end of the chamber. By having the chamber near the outlet end, a large pressure drop across the chamber is insured. Moreover, the valve at the end of the chamber insures that the large pressure drop will be maintained even during start-up of dispensing. By increasing the pressure drop over the chamber, mixing therethrough has been greatly enhanced. Therefore, a smaller mixture is required for effective mixing. The result in small size makes the static mixer capable of being hand held, in the form of a dispensing gun and the valve actuator is part of the dispensing gun so that the valve can be operated by the same hand that is holding the gun.
