The coated woven a term used in the production process, its principle is applied to the substrate woven resin in the molten state. Only the molten resin is coated onto the woven cloth and immediately cooled to obtain the woven fabric of combinations. If the composite, the molten resin film is sandwiched in the middle of the woven fabric, and paper or plastic film, and then cooled to obtain a triple woven fabric is coated can be flat woven sided coated cloths can also be coated on both sides of the tubular fabric. complex, coated tube cloth. Coated woven printing, cutting, stitching made from a variety of bag type, the wide coated cloth take-up as a tarp factory. The coated process indicators is the temperature, pressure, control of the thickness, the coated peel strength.
Plastic woven bag production operation steps
1. Before starting the operation (1) name or the measurement required raw materials drying stirring. Mixed with the raw material of the particles of recycled material, recycled material particles added to the dry blender mix heat. Recycled material particles mixed with hot temperature control about 80 ℃, released in the heat of the spices box to the number of temperature settings. Stirring the temperature to 500 ° C and then new material is added to the dry mixer filled masterbatch materials continue stirring, masterbatch into powder. Timely required add coloring pigment coloring pigment, about stirring the lmin released Stir in spices box with recycled material particles. If the raw material is a powder doped regrind particles, first mix heated to about 70 ° C add padding masterbatch stirring continued regrind particles, to a temperature setpoint played placed spices box and after the release of the powder and stirred uniform stand . Regrind particles need to add paraffin, first regrind particles mix heat to about 70 ° C, the paraffin wax is processed into small pieces cast stirring continued. (2) added to the extruder hopper with a good resin. (3) open the cooling water valve of the tank. (4) meet the requirements when the extrusion temperature, the thermostat 15min.
2. Boot steps (1) start Extruder motor about 30s immediately shut down, and observed that there is no anomaly, if it is not normal immediately repair. The pending the enemy troubleshooting and then start the motor running. (2) Start the the drafting machine's electromagnetic motor speed, the speed to the desired position. (3) all motor start winding machine, and adjusted the desired speed. (4) When the melt extruded from the die orifice by O. Dirt and 2mm thick plug piece cleanup die die lips coke material. (5) The flat membrane pull the film roll wound on the drafting machine, to be flat membrane cleaning without spot from the tank, the flat membrane traction by slitting frame, blank roller of the guide wire, I oven, stretching guide silk roller II oven, setting the guide wire roller, and then marked the turret knife to level the film cut into wire billet the process treatment form required Biansi, and then wire around the unit around the wire in order.
3. Normal operation (1) when the machine was operating normally, according to the required thickness of the flat wire adjustment extruder, drafting machine, winding machine speed. (2) to adjust the the two oven temperature. (3) Adjust the tension of the winding wire, 15A regulator adjusted to 100 ~ 160V, a distance, between flat wire drawing machine and winding machine flexibility. (4) The time the observed slice thickness of the film, once the piece gradually thin film immediately stop replacement filter. 4. Parking step (1) before shutting down the barrel, three-way, die heating temperature controller is reduced by approximately 20 ° C. (2) reduce the screw speed to zero, and to close the extrusion machine motor, while reducing the drawing speed to zero to close the drafting machine motor. (3) finding a flat wire. Cut wire from the winding machine as close as possible. (4) Close all motor winding machine. (5) Close all heater power.
