METHOD OF FORMING OF A CONTINUOUS LENGTH PROFILE OUT OF FOAM POLYSTYRENE Russian patent published in 2005 - IPC

FIELD: construction materials industry; refrigeration industry; methods of production of articles out of heat-insulated foam polystyrene.

SUBSTANCE: the invention is pertaining to the methods of production of articles out of heat-insulated foam polystyrene and may be used in construction materials industry and refrigeration industry. The method of forming of a continuous length profile out of foam polystyrene by in series forming-on each next formed component of the profile to a previous one provides for the repeated cycles of filling of the forming chamber with granules of previously foamed polystyrene (foam polystyrene). Then conduct their thermal treatment with a heat-carrying agent, vacuumization, removal of a condensate and pushing the formed component of a profile ahead. Then before pushing the formed component of a profile ahead vacuum-pump the forming chamber filled with granules of foam polystyrene and feed the heat-carrying agent in the forming chamber and not terminating feeding of the heat-carrying agent switch-off the vacuum-pumping system, turn on the cock of the condensate removal system and conduct the further thermal treatment during a normal time. In the capacity of the heat-carrying agent use a steam. All the operations are carried out in one zone before pushing the formed component of a profile ahead. The technical result consists that due to combination of a formed component thermal treatment with vacuumization and removal of condensate a component of the profile production cycle time is shortened.

EFFECT: the invention allows to shorten the time of a formed component of the profile production cycle.
