1. The Carton Window Pasting Machine mainframe adopts 30mm steel wall. The steel plate is dealt with heat treatment and processed by digit control machine. It runs smoothly with high quality stability. The machine is comprised of 5 units of feeder, positioning, gluing, patching and delivery unit.
2. The feeder adopts imported Ever-power scratch furrow conveyor belt from USA. Matching by our unique supporting plate intermittent feeding mode, the paper feeding is very smooth and no overlapping paper or missing paper, which makes the machine speed up to 7000 sheet/hour.
3. The air draft conveyor belt and paper delivery conveyor belt are imported from Schneider. The mechanical transmission driving train is from Japan.
4. The key components of the machine adopt NSK bearing from Japan. The buttons of the control system and contactor adopt SCHNEIDER-KREUZNACH. Human-computer interface is from Taiwan Wenview. PLC transducer is from DELTD. All photoelectric switches are from Omron. The Electric motor is from Taiwan(TECO YV)
PVC is prepared by free radical addition polymerization. The polymerization method is mainly divided into suspension polymerization method, emulsion polymerization method and bulk polymerization method. The suspension polymerization method is mainly used, accounting for about 80% of the total PVC production. The pure water, the liquefied VCM monomer and the dispersing agent are added to the reaction vessel, and then the initiator and other auxiliary agents are added. After the temperature is raised to a certain temperature, the VCM monomer undergoes radical polymerization to form PVC particles. The continuous agitation causes the particle size of the particles to be uniform and the resulting particles to be suspended in water. In addition, the resin for PVC paste is produced by the microsuspension method, and the product properties and pasteability are good.
