Correlation between Profile Pvc and plastering mortar

When subjected to tensile deformation, plastering mortar must work in coordination with Profile Pvc, and the two materials must have a good correlation. Wall Corner with poor correlation with plastering mortar, no matter how high its strength is, will inevitably crack in the early stage.

When the protective surface layer begins to bear tension, the Profile Pvc should be able to be in a stress state as soon as possible to exert its tensile properties and disperse the stress. Although the Profile Pvc cannot prevent the plastering mortar from forming the first crack when a certain tensile strain is reached, it can effectively delay the development time of the first crack and limit the development width of the first crack, and distribute stress through its warp and weft nodes, so that the entire plastering mortar is evenly stressed and the cracks are evenly distributed.
1. Higher node strength
If the node slips when the Wall Corner is tensile, the stress will be borne by the plastering mortar in the early stage of stress, resulting in cracks.
2. Lower tensile strain
If the node does not slip when the Profile Pvc is tensile, and the tensile strain is large, it will also cause the plastering mortar to crack in the early stage.
The tensile strain of Profile Pvc includes the strain in the early stage of tension and the strain at break. It can be expressed by the tensile force at elongation of 0.25%, 0.5%, and 1.0% respectively; as well as the tensile force (breaking strength) and breaking strain at break.
3. Smaller yarn deflection
It is inevitable that the yarn will deviate during the weaving of Wall Corner. If the deviation is too much, it will lead to eccentricity when subjected to force, which will also affect the use effect.
