Apparatus for pneumatically discharging liquified building material containing a hardener |
摘要 |
An apparatus for pneumatically discharging a liquified building material includes a first source of liquid hardener and injection means for injecting the liquid hardener perpendicularly into the air-entrained building material at the discharge nozzle. The liquid hardener may be supplied through an atomizer and injected through openings that are enlarged. A second source of liquid hardener may be provided to supply a second hardener mixed with the airstream that entrains the building material. A flexible tubing may be provided between the aeration fitting and discharge nozzle to require that only the discharge nozzle be lifted by the operator.
