PVB

INTERLAYER FILM

PVB IS A BONDING MATERIAL USED IN THE MANUFACTURING OF LAMINATED GLASS. THIS PRODUCT A PVB FILM WITH INSULATION FUNCTION BY ADDING NANO I.M TO PVB

Product Features And Advantages

*Rich in color, diverse in variety

  • Our company produces various types of color PVB films, including domestic and export color schemes.
  • Including; porcelain white, milk white, matte, green, ocean blue, brown, gray, blue star gray, European gray, and so on.

*Excellent chemical propers

  • Transparent, heat resistant, cold resistant, moisture resistant, and high mechani- cal strength PVB interlayer film is a semi transparent film made of polyvinyl butyral resin plasticized and extruded into a polymer material.
  • The appearance is a semi transparent film, free of impurities, with a flat surface, a certain roughness and good softness, and has good adhesion to inorganic glass.

*Outstanding physical properties

  • PVB interlayer film is currently one of the best adhesive materials for manufacturing laminated and safety glass in the world, with the performance of safety, anti-theft, explosion-proof, sound insulation, and energy saving.

PVB Film Production Proces

1. Laminated Glass

  • Lamination Room: Temperature should be 20-25°C, below at 30%, Dust proof and keep the machine clean and tidy, workers need to keep uniform, cap and grove clean in order to avoid the adhesion of dust, impurities and hair.
  • Conditions: The temperature of lamination is suggested to be 20-30°C, the highest temperature should be no more than 40°C. temperature of PVB suggested to be 20-25°C. PVB film and glass need to be checked several times if they are clean and matched or not.

2. Process of Pre-Pressing

  • Cold Drawing: Temperature: 20-25°C Stress:-0.095-0.1mpa.2-15minutes in the continuously cool drawing.
  • Heat Drawing: Temperature of glass should be 100-120°C, 30-45minutes, Stress between -0.095–0.1mpa, take out the glass when temperature rise up to.

3. Process of Rolling Method

  • Thermostat pre-heating the lamination glass temperature is 20-30°C, humidity of 25% first temperature 100-120°C, first roller, pressure is 0.2-0.5mpa, the roller distance should be less than 1mm of laminates glass thickness.
  • Second thermostat temperature 160-180℃. third thermostat temperature 220-240°C.
  • second roller, pressure 0.3-0.5mpa, the roller distance should be less than 2mm of laminated glass.
  • Keep the thermostat temperature by continuous work.

4. High Pressure Formation

  • The temperature and pressure should be risen or slow down at low speed during the whole procedure. As reference following:
  • 1. Raise the temperature and pressure-up to 60°C, pressure to 0.4mpa.
  • 2. Temperature to 90°℃, pressure to 0.8mpa.
  • 3. Temperature to 120-130°C, pressure to 0.1mpa-pressure to 1.1-1.13mpa.
  • 4. Keep temperature 30-60 minutes (depend on the glass thickness and quality in the autoclave.
  • 5. keep the temperature down to 90°C with the stable pressure. Exhausting with temperature down to 45-55°C.
