According to a production technology for partition bricks, various raw material bins, a polystyrene particle bin, a polystyrene raw material bin, a bulking machine, a volume measuring device, a primary bulking bin, electronic balances, a screw conveyor, a water pump, a mold combination, a stirring machine, a mold vehicle and an additive warehouse are included. The technology is characterized in that the electronic balances are mounted at outlets of the various raw material bins to be butt-jointed with the screw conveyor, and an outlet of the screw conveyor is connected with the stirring machine; addition of polystyrene particles is controlled by the volume measuring device, water is added, various additives are added manually, stirring is performed, and the water mixture is poured into themold combination to be molded; solidification is started after the water mixture is poured into the mold combination and left to stand; a formula is as follows: lime residues, boiling slag, lime powder, fine sand and cement form a dry mixture; each ton of the dry mixture is mixed with the polystyrene particles, the water and the additives to form a wet mixture; the lime residues and the boiling slag are used as aggregate, and the aggregate has the certain strength after being solidified; manual demolding is performed after bricks are transported by the mold vehicle after mold filling to the standing field for 24 h, the bricks are stacked, water is applied for maintenance, the bricks are stored after the final setting period, and the bricks are purely nature, green, healthy, ecological andenvironment-friendly wall materials.
