Protective Clothing Liquid Resistance Static Pressure Tester

Instrument use:

The acid-proof clothing material anti-seepage acid static acid pressure tester is used to measure the acid-base anti-seepage of breathable acid-base protective clothing materials - static acid pressure resistance and liquid static pressure resistance.

Working principle:

The resistance to liquid static pressure borne by the fabric is used to indicate the resistance encountered by the test liquid through the fabric. Under the atmospheric pressure of 101.325kPa, the bottom of the sample is subjected to a continuously rising liquid pressure. Until there are three leaks, and the height of the liquid column at this time is recorded, which is called the fabric resistance to liquid static pressure.

Technical parameters:

1. Test solution: 80% concentrated sulfuric acid with different concentrations of acid and alkali

2. Rising rate of acid pressure test solution: (60±3) cm/min

3. Maximum pressure: 150mm liquid column "Maximum acid pressure: greater than 150mmH2SO4 (80%)"

4. Range: 0~150mm liquid column "0~150 mmH2SO4 (80%)"

Test preparation:

Take 3 samples from the finished protective clothing with a diameter of 32mm

Test steps:

1. The reagent contacts the sample vertically from below

2. Pressurize the reagent continuously and stably

3. Observe the sample and record the static pressure of the liquid when the third liquid drop appears on the sample

4. Each sample should be tested 3 times, and the arithmetic average is taken to obtain the static pressure value of the sample
