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 continuous switching of double filter chambers. It continuously filters high polymer melt to remove impurities and unmelted gel particles, which improves the spinning performance of the melt and ensures high spinning quality.
What materials can be filtered using the CPF series product?
Filterable materials include 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 available for the CPF series filters?
The standard sizes for the CPF series include Outer Diameter (OD) 42 mm with lengths of L460 mm, L750 mm, and L1150 mm.
What are the specifications of the 75μm candle filter?
The pleated 75μm PET candle filter has an outer diameter of 46.5 mm, a length of 512.0 mm, a filtration fineness of 75μm, and a total filter area of 0.30 m². The flow direction is designed from the outside to the inside.
How is the wire mesh structured in the 75μm candle filter?
It features four layers of stainless steel woven wire mesh structured from outside to inside as follows:
1. 20 mesh (W 1.0 mm, d 0.40 mm)
2. 50 mesh (W 0.34 mm, d 0.16 mm)
3. 180 mesh (W 0.075 mm, d 0.050 mm)
4. 20 mesh (W 1.0 mm, d 0.40 mm)
Why is the CPF series filter essential for high-speed and recycled spinning?
It is indispensable because it effectively removes unmelted gel and impurities. This plays a critical role in extending the operational lifespan of spinning components, improving overall equipment utilization, and increasing production output.
