Methods for processing interface compatibility in wood-plastic composite materials (2)
The most common method for handling the interfacial compatibility of wood-plastic composites in industrial production is chemical methods. Because coupling agents can form covalent or complex bonds between wood and plastic, and act as “molecular bridges”, they are often used to impro...Read more -
Causes of uneven thickness of PVC sheet
The uneven thickness of PVC sheet is mainly due to poor plasticization and the large difference in the ejection speed, or the large amount of precipitates adhered to the cavity and the confluence core. Properly adjust the die temperature corresponding to the thin part of the plate to increase th...Read more -
Reasons for yellowing and darkening of PVC profile
The yellowing and darkening of the PVC profile may be due to the insufficient amount of stabilizer, which leads to poor thermal stability in the system and causes yellowing of the powder when heated. Insufficient external lubrication causes excessive friction between materials and equipment, and ...Read more -
