          How to solve acrylic products processing scratch problem

          Add Date:2015/5/22 Hits:3104 Font Size:S M L Back
          First, the new national standard material acrylic sheet acrylic products technology-related industries (GB7134-86) are:
          1, the standard tolerance: the sheet format 1.0 × 1.3m as standard, larger than this format allows for increased accordingly.
          First grade: <5mm: ± 12% -20% ≥5mm: ± 10%
          Second Grade: <10mm: ± 12% -40% ≥10mm: ± 10%
          2, deformation temperature: 750 ℃ -84 ℃
          3, the standard specific gravity: 1.19 ± 0.02
          Second, the processing of note:
          1, renewable materials more than the new plate material soluble in organic solvents, paint filled engraving after causing cracks often appear silver, the general solution has the following three ways:
          A selection of acrylic paint (resin) general store to buy art.
          B selection amino paint, general chemical store to buy.
          C fill paint and then polished.
          2, for some minor scratches the surface of acrylic or less obvious damage treatment, commonly used sandpaper wet grinding, polishing sandpaper to ring when moved to the fineness of sandpaper gradually increased to more than 600 mesh, can finally rub toothpaste Grinding can.
          3, easily adheres to the plate electrostatic dust before printing or use a chamois or fill paint stained 1% soapy water, soft cloth to wipe clean, in order to achieve clean results.
          Third, the board size actual weight
          Because it is the original small-scale processing factories in production are based on a template casting the feed hose with the increase in the thickness of the acrylic sheet increases, take up more space in the plate, so the same cast out of acrylic templates The thicker the sheet thickness, the smaller the size of the finished sheet. However, the list of manufacturers in the writing just writing template uniform size, rather than the specific dimensions of the thickness of the acrylic sheet, the product specification error occur there, so manufacturers in all weighing settled. Ruofu weighed and manufacturers to provide the difference ± 0.3kg considered reasonable. However, for the convenience of everyone in sales, basically theoretical calculation based, simple formula is: The actual length (m) × actual width (meters) × actual thickness (mm) × specific gravity (1.2) two kilograms. Weight and weighing error theory calculations to pay special attention in thick acrylic sheet, the board thickness measurements are generally 15 mm or more should be calculated to the millimeter, in order to ensure not the actual weight difference is too large.
