Low-smoke halogen-free cable material production line
Granulating process:Kneader--- Conveyor---Conical Force Feeder---Two stage extruder---Hot Cutting Assistant Machine
1. Basic formula ingredients: resin particles (evalue) flame retardant (aluminum hydroxide, magnesium hydroxide, etc.), auxiliary powder (flame retardant synergist\lubricant, antioxidant, etc.), auxiliary particles (silicone Ketone masterbatch, etc.), auxiliary liquid (coupling dispersant).
2. Basic process route
The flame retardant and auxiliary powder are first metered into the high-speed mixer, and then the auxiliary liquid is added for coupling and dispersion of the powder surface. After the surface treatment is completed, the resin is added, mixed evenly, and then put into the internal mixer for banburying. After the banbury is evenly mixed, the lambda double cone feeder is used, and the granulation is carried out by two-stage mixing. Considering the material's ability to absorb moisture, the granulation method of air cooling and eager cutting is preferred.
3. Applicable products: high and low temperature low-smoke halogen-free cable material, radiation cross-linked low-smoke halogen-free cable material, high flame retardant cable material, etc.
