How to reinforce the brittle stone? (1)

The reinforcement of the plate is divided into two ways: the back net reinforcement on the back of the plate and the penetration reinforcement on the surface of the plate.
1. "Back net" reinforcement
"Back net" reinforcement refers to that the mesh size of fiber protective mesh with high strength is generally 5 × 5mm, which is bonded to the back of the board through epoxy resin, and the strength of the board is strengthened after drying. The width of the whole coil of fiber protection net is divided into different specifications from 1.2-1.8m, and the weight is generally about 900g / m2.
According to the actual needs of plates, "back net" reinforcement technology can be used to strengthen marble, granite, travertine and onyx, etc.
The viscosity of the glue reinforced by the back net is relatively low, and it takes 6-9 hours to reach the curing at normal temperature. If the drying oven heating method is adopted, the complete curing time can be obviously shortened. When the ambient temperature is too low, the glue will thicken and the curing speed will be slow. The glue liquid can be thinned by heating the glue, heating the stone or increasing the temperature of the construction environment to speed up the curing speed.
The setting time is an important process parameter of the back mesh reinforced plate, which depends on the number and output of the back net reinforcement plate, the operation mode of the back net process, and whether the drying furnace is selected or the drying capacity of the drying furnace is selected. If the number of plates to be strengthened in the production line is large and the production requirements are high, the mechanized back net reinforcement method can be adopted, and the natural complete curing method at room temperature can be selected, or the drying furnace with plate curing heating can be selected. If the production requirement is very high, even the vertical drying furnace can be selected.
For some production lines with small amount of reinforcement and low output, manual back net operation mode and natural full curing method at room temperature can be adopted.
