Selection of PVC hose production equipment and formula use.
PVC hose uses suspension polyvinyl chloride as the main raw material, adding a certain proportion of plasticizers, stabilizers, lubricants and other auxiliary materials. After mixing evenly, it is granulated and then made into products using an extruder.
Because of different production formulas, PVC hoses can have different characteristics. Due to the addition of plasticizer, this PVC hose is very soft and can be bent at will, which is different from PVC hard pipes.
PVC hoses mainly replace rubber pipes to transport various liquids, and can also be used as cable casings and insulating sheathing pipes for wires.
PVC hose production line process: Proportional measurement - Mixer stirring - Mixing and granulation - Extruder - Mold - Shape cooling - Traction - Rewinding - Inspection - Packaging and storage.
The selection of PVC hose production equipment is also different from that of general PVC hard pipe extrusion. The extruder generally uses a single screw. The screw structure is an equidistant and unequal depth gradient type. The length-to-diameter ratio is in the range of 18-25, and the compression ratio is 2.5-3.5. between. The selection of granulation equipment in the previous process will not be introduced here. If anyone needs this type of equipment, please contact us.
