Analysis on the Causes of Warpage of Artificial Stone Plate
1. Uneven structure caused by the deformation of a balanced structure of the material (Figure 1), is a A-A geometric symmetry plane for the symmetrical center. Therefore, due to thermal effects and other reasons, perpendicular to the A-A surface deformation can offset each other. Unbalanced structure of the plate is not. (1) deformation caused by the gel coat layer In order to make the artificial marble surface smooth, light, to mention the durability of products, in its surface coated with a layer of thickness of about 0.2 ~. .4 mm pure resin layer, or gel coat layer. Its existence seriously damaged the balance of the structure of the plate. When the sheet is subjected to thermal effects (the heat of the curing process, the drying of the drying room, the outdoor exposure, etc.), the difference in the shrinkage rate between the unbalanced structures
Generally related to the wood there is the temperature there is the degree of drying of wood generally easy summer Alice
In the process of production and use of man-made marble (both of which are the plates), the general problem encountered is warping, which has become an obstacle to the continued development of artificial marble. In this regard, we are inside and outside the province of some factories, the use of units were investigated. , Ren Wen on the artificial marble warping deformation of the reasons, how to avoid or reduce the deformation and other issues put forward some comments for the discussion. (A) artificial marble deformation in the production process Artificial marble is a very uneven structure of the composite material. Strictly speaking, its warp deformation (absolute deformation) is unavoidable (the deformation referred to in this article refers to the deformation within the required range, not the absolute deformation). Production of some unreasonable process, the ratio and often exacerbated its deformation.
In fact, the core is not flat, how can there be so much nonsense, the core plate did not hot chop.
