1. The Window PVC Patching 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 YVF).
According to the scope of application, PVC can be divided into: general-purpose PVC resin, high-polymerization PVC resin, cross-linked PVC resin. The general-purpose PVC resin is formed by polymerization of vinyl chloride monomer under the action of an initiator; the high polymerization degree PVC resin refers to a resin obtained by polymerizing a chain extender in a vinyl chloride monomer polymerization system; the crosslinked PVC resin is A resin obtained by polymerizing a crosslinking agent containing a diene and a polyene into a vinyl chloride monomer polymerization system.
According to the method for obtaining vinyl chloride monomer, it can be divided into calcium carbide method, ethylene method and imported (EDC, VCM) monomer method (the ethylene method and the imported monomer method are commonly referred to as ethylene method).
According to the polymerization method, polyvinyl chloride can be classified into four major categories: suspension polyvinyl chloride, emulsion polyvinyl chloride, bulk polyvinyl chloride, and solution polyvinyl chloride. The suspension method of polyvinyl chloride is the largest variety of production, accounting for about 80% of the total PVC production. The suspension method of polyvinyl chloride is divided into six models according to absolute viscosity: XS-1, XS-2, ... XS-6; XJ-1, XJ-2, ..., XJ-6. The meaning of each letter in the model: X-suspension method; S-loose type; J-tight type.
According to the content of plasticizer, PVC plastic olefin plastic is often divided into: no plasticized PVC, plasticizer content is 0; rigid PVC, plasticizer content is less than 10%; semi-rigid PVC, plasticizer content It is 10-30%; soft PVC, plasticizer content is 30-70%; polyvinyl chloride paste plastic, plasticizer content is more than 80%.
