Swelling Dissolution And Dispersion Production Line

After melting, ultra-high molecular weight polymers have high viscosity, making it impossible to process them into films or spin fibers directly. Plasticizers need to be added into the polymer resin in proportion. Utilizing the structural characteristics of co-rotating twin-screw extruder, it is possible to achieve the processes of conveying, shearing, mixing, stirring, heating, and pressurizing, thereby completing continuous swelling, dissolution, and degassing, obtaining thermodynamically stable homogeneous film-forming or spinning. Subsequently, during the cooling process of the melt blend, phenomena of solid-liquid phase or liquid-liquid phase separation occur, and finally, film or spinning is pressed. This process route features continuous production, precise control of process parameters at each stage, uniform pore structure, high porosity, good strength, and stable quality, and has been widely used.

Application:

• HMWPE swelling, dissolution, homogenization – film production, spinning
• Aramid fiber swelling, dissolution, homogenization – film production, spinning
• PE swelling, dissolution – film production
• Raw wool swelling, dissolution, defoaming-spinning
