Zeolite silicon nitride trepanning hollow ceramic microspheres are evenly distributed on governing belt balance, and spray thrower is by the sodium metasilicate of modulus 3.2~3.5
It is uniformly sprayed at the outer surface of zeolite silicon nitride trepanning hollow ceramic microspheres, zeolite silicon nitride trepanning hollow ceramic microspheres are with speed governing
Belt conveyer scale, which enters in inside spin drum agitation device, to stir evenly, then mixture is sized mixing with 0.5~0.7 ratio of mud, finally adds
Enter the aluminium powder cream that mixture total weight is 0.2~2.0% to stir evenly, aluminium powder cream hydration reaction generates bubble, forms porous expansion
The slurries of water suction；
The preparation of third step, the porous sponge brick that catchments：The slurries of porous expansion water suction prepared by second step are stirred evenly and are poured into
In the die trial of sponge brick press, through striking off, suppressing, demould, dry, the porous sponge brick that catchments is made（1）, porous sponge of catchmenting
Brick（1）A face be in dovetail groove（2）Shape, collector pipe（3）Embedded dovetail groove（2）It is interior, collector pipe（3）Embedded dovetail groove（2）It is interior
A part of arc surface be openning shape, another part arc surface be closed, rainwater pass through the porous sponge brick that catchments（1）Remittance
Collection, into dovetail groove（2）It is interior, entered collector pipe by the effect of gravity（3）, collector pipe（3）By the single porous sponge brick that catchments（1）
It links together, collector pipe（3）The rainwater collected enters in collecting-tank.
