Glass rod and plastering glue are closely related

When subjected to tensile deformation, the plastering glue must work in harmony with the Fiber Glass. The two materials must have a good correlation. No matter how high the strength is, cracks will still occur in the grid cloth that has a poor correlation with the plastering glue. Produced in the early stages.

When the protective surface layer begins to bear tensile force, the glass rod should be in a stressed state as soon as possible to exert its tensile properties and disperse the stress. Although the glass rod cannot prevent the plaster mortar from producing the first crack when it reaches a certain tensile strain, it can effectively delay the development time of the first crack and limit the width of the first crack, and pass its longitude and latitude directions. The nodes distribute stress so that the entire plaster mortar is evenly stressed and cracks are evenly distributed.
In Europe and the United States, it is generally believed that cracks with a width of less than 0.2mm are harmless cracks. For the external wall insulation system, the more important thing is not to prevent the occurrence of cracks (just like steel bars cannot prevent the cracking of concrete, whether the plaster mortar eventually cracks depends on its cracking strain), but to delay the deformation time as much as possible, thereby delaying cracking, while limiting the width of a single crack.
