The 5th step. Pressure water discharging:
After the vibration moulding, open the oil cylinder motor, the oil cylinder pressure head is pressed in the mould exerts pressure to slurry, when being designated as 1Mpa～5Mpa, oil cylinder oil pressure gauge outfit shuts down, and keep-uped pressure 5-15 minute, be controlled in the scope of 0.5ml～1.5ml with the water-intake rate that guarantees product, in the time of draining, the water of discharging wiped with wet rag; Clear up peripheral excessive slurry;
The 6th step. leave standstill and wipe one's face:
Draining is unclamped tight locking button after handling, and together with carrying is dull and stereotyped slab body after the moulding is moved to quiet elsewhere putting, and touches face with building iron plate by laying bricks or stones after 20 minutes-40 minutes; Demoulding water curing after 20 hours-30 hours; Reuse behind the mold cleaning;
The 7th step. water curing:
The maintenance pond is arranged on nonventilated indoor, and the slab body after the demoulding is put into the pond, puts into potable water, and water level must exceed base substrate end face 20mm-40mm; Maintenance 4 days-8 days;
The 8th step was deposited maintenance:
Base substrate after the water curing takes out from the pond, dries surperficial trickle, promptly moves to be placed on nonventilated indoorly, deposits 60 days-100 days;
The 9th step. surface treatment:
Use electric hand angular grinder, device stone material cutting blade, with concrete slab angle at 45, reciprocal frosted concrete slab surface, the polishing scratch degree of depth is controlled at and is no more than 0.5mm, until the entire plate surface;
The tenth step. check:
Press JC/T547-2005 " ceramic wall and floor bricks tackifier " standard appendix A regulation, production board is carried out the project check, and the processing of testing;
The 11 step. finished product:
