When setting the operating parameters of the stone paper production line, multiple aspects need to be considered comprehensively to ensure a smooth production process, stable product quality, and achieve high efficiency and economy. Here are some key operating parameters and points to note:
1. Raw material pretreatment parameters
Drying of raw materials: ensure that raw materials such as stone powder are fully dried before use to avoid foam or poor melting during extrusion due to excessive moisture.
Proportioning ratio: Accurately control the ratio of stone powder to resin to ensure the performance and stability of the product.
2. Operating parameters of extruder
Temperature control:
The temperature of each extrusion area (feeding section, melting section, homogenization section, mold section) needs to be set reasonably to avoid overheating that may cause degradation or poor plasticization of raw materials.
Set appropriate processing temperature curves based on different resins and additives.
Screw speed:
The rotational speed of the screw has a direct impact on the melting, mixing, and output efficiency of the material, and needs to be set according to the material characteristics and production requirements.
A higher rotational speed can help increase production, but it may also increase shear heat and requires moderate adjustment.
Back pressure:
The back pressure setting needs to be appropriate to effectively control the flow of the melt, ensure uniform material flow, and avoid unstable situations.
3. Molding and cooling parameters
Mold design:
The temperature, shape, and flow channel design of the mold need to be combined with product specifications and requirements to ensure the uniformity of plasticization and molding.
Cooling method:
Appropriate cooling methods (such as water cooling, air cooling, etc.) ensure rapid solidification of the product and avoid excessive shrinkage or deformation.
4. Cutting and winding parameters
Cutting equipment settings:
The cutting speed and cutting method need to be optimized to ensure that the edges of the cut stone paper are smooth and free of burrs.
Winding tension:
Suitable tension should be set during winding to ensure that the product is tightly wound and avoid looseness or unevenness.
5. Quality control parameters
Online monitoring:
Set up an online detection system to monitor key indicators such as finished product thickness, flatness, and smoothness in real-time to ensure product quality.
Regular evaluation:
Conduct regular sample inspections (such as strength, water absorption, etc.) and physical property tests to evaluate the consistency and stability of the production process.
6. Environmental control
Factory environment:
Control the temperature and humidity in the workshop to avoid negative effects of high temperature or humidity on the quality of raw materials and finished products.
7. Safety and Environmental Protection
Formula safety:
Ensure that raw materials and additives used in the production process comply with safety and environmental standards, and avoid the release of harmful substances.
Waste disposal:
Establish a reasonable mechanism for waste recycling and disposal to meet environmental requirements and reduce resource waste in the production process.
Drying of raw materials: ensure that raw materials such as stone powder are fully dried before use to avoid foam or poor melting during extrusion due to excessive moisture.
Proportioning ratio: Accurately control the ratio of stone powder to resin to ensure the performance and stability of the product.
