Frequently Asked Questions (FAQ)
What is the primary function of the CPF series melt filter?
The CPF series melt filter is a chemical polymer filter designed with double filter chambers for continuous switching. It is used to filter high polymer melts continuously to remove impurities and unmelted gel particles, which improves spinning performance and ensures high spinning quality.
What materials can be filtered using the CPF series?
It can filter fluid (melt) polymers, prepolymers, and monomers. This includes thermoplastic polymers such as polyester (PET), nylon (PA6, PA66), polypropylene (PP), polyethylene (PE), polyurethane (PU), and other viscous thermal fluids.
What are the standard sizes and dimensions available?
Standard sizes include outer diameters of 42 mm with lengths of 460 mm, 750 mm, and 1150 mm. The pleated candle filter configuration has an outer diameter of 46.5 mm and a length of 512.0 mm.
What is the structure and flow direction of the filter media?
The filter media consists of four layers of stainless steel woven wire mesh. The flow direction of the fluid is designed to run from the outside to the inside, providing a total filtration area of 0.30 m².
How are the wire mesh layers configured?
From the outside to the inside, the four layers are configured as follows:
First layer: W 1.0 mm, d 0.40 mm (20 mesh);
Second layer: W 0.34 mm, d 0.16 mm (50 mesh);
Third layer: W 0.075 mm, d 0.050 mm (180 mesh);
Fourth layer: W 1.0 mm, d 0.40 mm (20 mesh).
In which spinning processes is this filter indispensable?
It is an indispensable equipment in high-speed spinning, fine denier spinning, and recycled material spinning (such as foam bottle flakes). It effectively extends the lifespan of spinning components, increases equipment utilization, and boosts overall output.
