Galvanized steel wire mesh and fiber mesh cloth use performance is great competition
June 20, 2023
I believe that people engaged in the construction industry understand that galvanized steel wire mesh and fiber mesh cloth may wish to distinguish through the role of these two products in actual engineering:
First, galvanized steel wire mesh: masonry wall cracks are common quality problems in construction projects. Hot-dip galvanized steel wire mesh with its strong structure, strong integrity, high corrosion resistance in the external wall building insulation more and more important role.
Anti-cracking protective layer for tile finish. After curing and drying, the insulation layer is applied with anti-cracking mortar, and the thickness is controlled at 2 ~ 3mm. According to the structure size, cut the four corners of the net segment for laying. The length should not exceed 3m, and the corner of the net is folded into a right Angle in advance. Do not fold the net during the cutting process. The net should not be formed in the laying process. After the net is opened, the net should be laid smoothly in the direction. First, the four-corner net should be jammed with U-shaped clips to make it close to the surface of the anti-cracking mortar, and then the four-corner net should be anchored on the base wall with plastic anchors according to the bidirectional @500 plus-shaped distribution. The inner side of the window, parapet wall, settling joint and other steel wire mesh ends should be fixed on the main structure with cement nails and gaskets. After the four-corner net is laid and checked, the anti-crack mortar is applied for a second time, and the four-corner net is covered in the anti-crack mortar.
Second, the glass fiber mesh cloth plays the role of stress dispersion in the external insulation system, and together with the plastering glue, it forms the protective surface layer of the external insulation system to resist the cracking of the surface layer caused by natural temperature and humidity changes and accidental impact. The performance of the glass fiber mesh cloth and the compatibility with the plaster paste are also the anti-cracking of the external insulation system must be taken into account.
Third, the above two points, it is not difficult to see that the role of galvanized steel wire mesh and fiber mesh cloth in the external insulation construction is basically the same, but galvanized steel wire mesh is more suitable for all kinds of wall materials than fiber mesh cloth.
Generally, if we are in the corner of the wall, the intersection of the masonry and the concrete beam and column also needs to be set up galvanized steel wire mesh to improve the overall performance of the surface layer material.
