As the market demand for green building materials continues to grow, PVC Wallboard Production Line has optimized its operating procedures to ensure product quality and production safety. Experts pointed out that standardized operation is the core of ensuring product qualification rate, and the following links need to be focused on.
The raw material pretreatment link is particularly critical. Operators must strictly screen PVC powder and additives to avoid impurities; the moisture content must be monitored in real time during the drying process to ensure that the raw materials are fully dehydrated and prevent defects such as bubbles and color differences from the source.
The extrusion molding stage requires extremely high temperature control accuracy. The twin-screw extruder needs to be precisely controlled by zone, and the temperature difference between each zone must not exceed ±5℃ to avoid overheating and decomposition of the melt or insufficient plasticization. The screw speed and traction speed need to be dynamically matched to ensure uniform thickness and smooth surface of the board.
The embossing cooling process needs to strengthen synergy. The pressure of the calender roller is dynamically adjusted according to the depth of the pattern, and the matching 15-meter circulating water cooling system must ensure that the water temperature is constant at 20℃±2℃ to avoid deformation and warping of the board due to uneven cooling.
Safety protection measures are fully covered. Infrared emergency stop devices are installed in the high-speed operation area of PVC Wallboard Production Line, and operators must wear anti-static clothing and goggles; the cutting tool protective cover must be checked before starting each shift to prevent mechanical injury accidents.
Industry insiders emphasize that regular equipment maintenance is also indispensable. The screw needs to be cleaned of carbon deposits every month, the mold is polished and maintained every week, and the electronic control system is inspected and recorded daily. This can reduce the failure downtime rate by 30% and significantly increase production capacity.
The MES production management system can realize full-process data traceability from feeding to finished products. With the implementation of the new national standard "PVC Wallboard for Building Decoration", standardized and intelligent PVC Wallboard Production Line is becoming the mainstream direction of industry upgrading, injecting new momentum into the green home industry.
