The rotation of the PVC sheet is responsible for many parts. The main problem is that the geographical boundary is poorly controlled. Whether rolled or sheet flooring, most are available in PVC-based flooring. Due to environmental influences, the changes in thermal expansion and cold contraction of the PVC soil are different, resulting in soil expansion or contraction. The differences in thermal expansion and cold strain at different units are different, so the surface is distorted. During the design of the soil, attention should be paid to the proper use and balanced placement of materials to minimize soil erosion.
1. check if the PVC board overheats during stripping. If so, reduce the temperature in the tube.
2. is there any deformation due to internal stress. If so, decrease injection pressure.
3. my cross section is irregular and the taper is uneven. If so, reshape the mold with an equal cross section so it fills evenly.
4. the plucking pin is unbalanced. If so, adjust or discard the release switch.
The reasons for the PVC sheet are as follows: first, the control of the production process of the sheet is not there, and the good sheet must have the density of the pave and the same shape. If the difference is large, the forward expansion and contraction of the plate will be uneven, resulting in internal stress. Second, the water table is not properly controlled. The moisture content of the wood is more or less than the humidity of the air, causing it to easily warp and change. Therefore, it is necessary to keep water in moderation. Third, the mass of the plate is unclear. Due to the low density of the plate, the processing surface is not smooth, and it is easy to absorb moisture and change. Fourth, the waterproof function of the board is not qualified, and it is easy to absorb moisture and change. Fifth, caution does not qualify. If the PVC board is not stored in a dry and ventilated place, it is easy to affect the position of the board, resulting in deformation and other problems.
From a mechanical point of view, the sheet metal switch is the solution to the front release. If precautions are not taken in the production process, the board cannot compensate internally, resulting in deformation and changing the performance of the PVC board when it is made under high pressure and humidity.
