(12) pouring and filling half of the prepared slurry of the silicon-magnesium plant fiber composite material to the bottom of the positioned mould, and uniformly and symmetrically spreading two layers of glass fiber fibers or placing wax-free medium-alkali glass fiber cloth in the slurry to pour into the bottom plate of the partition wall batten;
(13) placing a panel supporting template on the bottom plate of the poured partition wall batten, pouring and filling the other half of the prepared slurry of the silicon-magnesium plant fiber composite material onto the positioned mould panel supporting template, and uniformly and symmetrically spreading two layers of glass fiber fibers or placing wax-free medium-alkali glass fiber cloth in the slurry to pour the slurry into the partition wall batten panel;
(14) and stacking the plurality of poured partition wall battens by adopting a moisturizing method, and then curing, wherein the curing temperature is 18-25 ℃, the moisturizing curing time is 72-120 hours, and the curing reaction temperature is not more than 70 ℃.
