Polyurethane Reactive (PUR) is called wet curing reactive polyurethane hot melt adhesive in Chinese. The main component is polyurethane prepolymer with end isocyanate. The adhesion and toughness (elasticity) of PUR can be adjusted, and it has excellent adhesion strength, temperature resistance, chemical corrosion resistance and aging resistance. It has become one of the important varieties of adhesive industry. It is widely used in packaging, wood processing, automobile, textile, mechanical and electrical, aerospace and other national economic fields. PUR adhesive is a molecular structure containing polarity and chemical activity of ammonia ester group (-NHCOO-) or isocyanate group (-NCO), and containing active hydrogen materials, such as wood, leather, fabric, paper, ceramics and other porous materials and plastics, metal, glass, rubber and other surface smooth materials have excellent adhesion.
Product use:
Woodworking cladding, textile fabric composite, PET transparent box, automotive interior parts. Headlights, bookbinding, adhesive production process occasions, widely used in printing, packaging, clothing and shoes, electronics, furniture and other industries of product assembly.
Product features:
1, the whole machine design by mechanical and electrical control system two parts with reasonable structure, easy operation and maintenance, the internal increase of space, so that the electronic control box has enough heat dissipation space, greatly reduce the damage of electronic components and power loss.
2, gear pump and motor connection using universal joint connection, its role is to make the transmission shaft at both ends of the Angle is equal to ensure that the output shaft and shaft into the instantaneous angular speed is always equal, to ensure the rubber machine in high-speed operation of stability and uniformity.
3. The press plate is made of aluminum alloy precision casting, processed by precision processing technology, and the surface is formed by DuPont Teflon deep penetration sintering treatment, which has the advantages of high coating strength and is not easy to fall off, reducing the phenomenon of hot melt adhesive carbonization.
4, the host adopts high-precision reflux valve (reflux valve sensitivity ±1bar), which has a locking function to avoid damage to equipment or personnel safety caused by misoperation, the whole filter design, the use of heavy multi-layer filtration, can prevent PUR glue expired suspected solid blockage phenomenon, pressure plate internal use pur glue overpressure protection, to ensure the stable and reliable operation of the system.
Note: The melting temperature of polyurethane reactive hot melt adhesive is lower than that of general hot melt adhesive (170-200 ℃), can be applied at low temperature, and can be used at 120-150 ℃. Save energy, reduce the corrosion of the sizing device, especially suitable for the bonding of heat-sensitive materials (such as plastics, etc.).
