Although the cement leakage board is widely used in the farm, and it takes a relatively long time. Although the cement leakage board is widely used and takes a long time, individual farmers also produce the cement leakage board themselves, but the quality of the cement leakage board is not particularly understood.

  To see the cement leakage board, first of all, it is to see whether the cement leakage board is mechanical or artificial, and then to measure the quality of the leakage board. Because the indicators of the mechanical board and the manual board are different, so when looking at the quality of the cement leakage board, we must first see that it is mechanical and artificial.

  First of all, the machine-made board is to see whether the surface is regular, whether the leakage hole is mellow, whether the water chestnut at the edge is removed, and then the thickness of the leakage board. The minimum thickness of the machine-made board is 10cm, and finally the weight. It must be compared with the weight of the hand-made board.

  Finally, from the perspective of materials, the sand is big sand, medium sand and fine sand, the size of stone, the cement grade, and then the thickness of the steel mesh, whether the steel mesh is connected in two layers or divided into main reinforcement and negative reinforcement. As well as the production of leakage board indicators can reach how much.

  We must distinguish the quality of the mechanical cement leakage board from the above problems.
