Classification and action mechanism of PVC heat stabilizers-2 Analysis on the principle of heat stabilizer required for PVC processingThe ideal PVC structure is the head-to-tail structure -CH2-CHCl-CH2-CHCl-, which is quite stable. However, the method of synthesizing PVC so far cannot achieve directional and regular polymerization of butadiene under the action of Ziegel catalyst like the synthesis of butadiene rubber. The polymerization of…
Classification and action mechanism of PVC heat stabilizers-1 Thermal stabilizers are a type of additive that can prevent or reduce the degradation or cross-linking of polymers due to heat during processing and use, and extend the service life of composite materials. Commonly used stabilizers can be divided into salt-based types, fatty acid soaps, organotin compounds, composite heat stabilizers and pure organic compounds according to their…
Classification and formula design principles of PVC lubricants The formula of PVC is the most complex of all plastics, and the most complicated part of the PVC formula is the application of lubricants. Proficient mastery of the classification and application principles of lubricants has positive significance for the optimization of PVC formulas.Classification and formula design principles of lubricants for PVC
What needs to be paid attention to during the operation and debugging of the extruder-2 6. The screw dry run test should not exceed 30min, connect the die head and pelletizing equipment after everything is normal, install the connecting bolts for the die head, and apply a layer of molybdenum disulfide or silicone oil before use to facilitate disassembly.7. In the early stage of feeding production, the minimum working speed of the screw should be used to feed less a…
