The impact of humidity on precision granite slabs \/ marble platforms, the core is: granite itself is very stable, but humidity can destroy through the environment, supporting structures, and measurement conditions.<\/p>\n\n\n\n

    \n
  1. Impact on the granite slab itself
    Granite has extremely low water absorption and excellent dimensional stability, it hardlyforms, cracks, or warps under normal humidity.
    Extreme high humidity for a long time will only produce a trace amount of moisture absorption expansion, which still affects micronlevel precision.<\/li>\n\n\n\n
  2. Impact on precision and measurement
    Dew
    High humidity temperature difference \u2192 Condensation on the slab surface
    Affects the measurement reading
    Ca rusting of workpieces and measuring tools
    Pollutes the work surface and destroys the gloss
    Environmental fluctuations
    Drastic changes in humidity can bring:
    Changes in the index of air \u2192 Affects optical measurements
    Surrounding clamping tools, measuring tools, and workpieces expand \/ contract inconsistently
    \u2192 The overall measurement error becomes<\/li>\n\n\n\n
  3. Impact on structures and accessories
    The platform’s brackets, adjusting feet, bolts, and bases are mostly metal:
    High humidity environments are prone to rust, jam, and expansion
    Leading to the platform being unable to be leveled, horizontal drift, and precision failure<\/li>\n\n\n\n
  4. Recommended usage environment
    Relative humidity: 40\uff5e60%
    Avoid: long-term >70%, direct sunlight, direct air conditioning, rapid dry-wet alternation
    Simple summary:
    Gran is not afraid of water, but it is afraid of the dew, rust, and environmental fluctuations caused by humidity. Humidity control is a key link to maintain precision.<\/li>\n<\/ol>\n\n\n\n
