Antistatic flame retardant PVC composite mining pipe
1. material selection
PVC resin, model S-1000, produced by Qilu Petrochemical Company; special conductive carbon black, flame retardant, stabilizer, processing aid, impact modifier, toughener, etc.
2. Major equipment
The unit for producing antistatic and flame retardant PVC composite mining pipes is composed of mixing equipment, twin-screw extrusion mixing equipment, and is composed of TAMM-150 high-speed thermal mixer and low-speed mixer
It consists of a pelletizer, a parallel twin-screw extruder, and a die.
The purpose is to fully mix various raw and auxiliary materials to make it a homogeneous multi-phase system and discharge it.
Moisture and volatiles in the material.
The twin-screw extrusion granulator is the main equipment for the production of leather-specific materials. THL-85 and THL-90 twin screw extruders are the main equipment for plasticizing materials. The core of forming antistatic and flame retardant PWC composite mining pipe lies in the structure and design of the machine head. The molding process adopts double machine coextrusion, and the special machine head is formed at one time. Its nose is characterized by a complex structure, which is more complicated. In the three layers of the mold, the inner and outer skin layers and the middle core layer are formed in the same model. The inner and outer skin layers and the core layer materials enter the flow channel independently. At the same time, the inner and outer skin layers and the core layer materials are composed of two units. The extruder feeds the materials separately, enters the common mold runner after completing the split in the three-layer common split mold, and extrudes through the common runner. The head and the extruder, the three-layer co-extrusion die and the common die are connected in a huff block manner.
In addition, the vacuum sizing spray cooling water tank is the pipe shaping equipment. The traction equipment keeps the pipe moving forward synchronously with the holding machine. The fixed-length cutting equipment cuts the pipe reaching the fixed length. neat.
Equipment main machine THL-85 type extruder and THL-90 type extruder head die are arranged in 9 °. At the same time, in the production process, the leather special material and the core ordinary material must be strictly separated, and added to the two hosts No mixing shall occur.
