A fire retardant treatment system for wooden fire doors

Abstract

The invention relates to a flame retardant treatment system for wooden fire doors, comprising a workbench, two sets of rails arranged symmetrically on the workbench, multiple sets of transport trolleys set on the tracks, and a driving part for driving the transport trolleys to move on the tracks , the jig placed on the transport trolley, the heating part for high-temperature treatment of the jig set at multiple intervals on the workbench, and the heating part alternately arranged on the working table for low-temperature treatment of the jig Cooling section and control system for controlling drive section, heating section and cooling section. There are many groups of transport trolleys, and the quantity of transport trolleys in each group is two and arranged on two tracks respectively. The invention is used for producing fire doors, and can make the fire retardant liquid penetrate into the inside of the door panels evenly.

Description

technical field [0001] The invention relates to the technical field of production of wooden fire doors, in particular to a flame retardant treatment system for wooden fire doors. Background technique [0002] Wooden fire-resistant doors refer to doors made of wood or wood products to make door frames, door leaf frames, and door leaf panels. [0003] The fireproof performance of wooden fire doors is realized by flame retardant liquid. During the production process, the fire retardant liquid needs to penetrate into the door panel. The amount of fire retardant liquid absorbed by the door panel directly affects the flame retardant quality of wood. The oxygen index is directly proportional to the flame retardant depth. The more the wood absorbs the fire retardant liquid, the better the fire retardant performance of the wood. [0004] In order to make the flame retardant liquid penetrate into the door panel as much as possible, it is necessary to destroy the structure of the cell...

AI Technical Summary

Problems solved by technology

[0004] In order to make the flame retardant liquid penetrate into the door panel as much as possible, it is necessary to destroy the structure of the cells, so that the flame retardant liquid can penetrate into the interior of the cell and between the cells as much as possible, but this method will reduce the strength of the door panel, and it is necessary to increase the strength of the door panel. The balance between fire performance and fire performance cannot be balanced

Another way is to use high pressure to force the fire retardant liquid into the interior of the door panel. This method uses pressure as the driving force for the penetration of the fire retardant liquid, which will still damage the internal structure of the door panel.
