  • Protective clothing acid and alkali resistance test equipment is used to determine acid and alkali impermeability of permeable acid and alkali protective clothing.2rITextile Testing Instruments, Testing Equipment Manufacturer
      2rITextile Testing Instruments, Testing Equipment Manufacturer
    Application:2rITextile Testing Instruments, Testing Equipment Manufacturer
    GB 24540-2009 protective clothing for acid and alkali chemicals.2rITextile Testing Instruments, Testing Equipment Manufacturer
    2rITextile Testing Instruments, Testing Equipment Manufacturer
    Working principle:2rITextile Testing Instruments, Testing Equipment Manufacturer
    The resistance of the test solution to penetrate the fabric is expressed by the hydrostatic pressure of the fabric. Under the atmospheric pressure of 101.325kPa, the lower surface of the sample bears a continuously rising liquid pressure. Until there are three seepage points, and record the height of liquid column at this time, which is called hydrostatic pressure resistance of fabric.2rITextile Testing Instruments, Testing Equipment Manufacturer

    Technical Parameters:2rITextile Testing Instruments, Testing Equipment Manufacturer
    1. Test solution: 80% concentrated sulfuric acid with different concentrations of acid and alkali2rITextile Testing Instruments, Testing Equipment Manufacturer
    2. Rising rate of acid fracturing test solution: (60 3) cm/min2rITextile Testing Instruments, Testing Equipment Manufacturer
    3. Maximum pressure: 150mm liquid column Maximum acid pressure: more than 150mmH2SO4(80%)2rITextile Testing Instruments, Testing Equipment Manufacturer
    4. Measuring range: 0 ~ 150 mm liquid column 0 ~ 0~150 mmH2SO4(80%%)2rITextile Testing Instruments, Testing Equipment Manufacturer

    Steps:2rITextile Testing Instruments, Testing Equipment Manufacturer
    1. the reagent contacts the sample from vertically below2rITextile Testing Instruments, Testing Equipment Manufacturer
    2. Continuously and stably pressurize the reagent2rITextile Testing Instruments, Testing Equipment Manufacturer
    3. Observe the sample and record the hydrostatic pressure when the third liquid bead appears on the sample2rITextile Testing Instruments, Testing Equipment Manufacturer
    4. Each sample shall be tested three times, and the static pressure value of the sample shall be obtained by taking its arithmetic mean value.
