Dissolvable Frac Ball HCL Acid Resistance Test
Experimental purpose: Obtain the acid corrosion resistance of the coating soluble ball
in a certain temperature and certain concentration of HCL solution
through experimental observation
Experimental steps:
1. Prepare experimental equipment, soluble ball, solute (HCL),
clean water, beaker, balance, vernier caliper Constant temperature
water bath
2. Check the appearance and size of the soluble ball, and take a
photo
3. Prepare 20% HCL solution
4. Immerse the coating soluble ball in HCL solution
5. The constant temperature box maintains the HCL solution at a
certain temperature, and observes the acid corrosion resistance of
the soluble ball
6. Take out the soluble ball at intervals, check the appearance,
shape and size of the soluble ball, and record the soluble ball
weight, reconstitute the acid solution, continue to observe the
corrosion resistance of the soluble ball
Test index: record the corrosion resistance of the soluble ball every 24 hours
Experimental considerations: every time during an acid resistance
check, pay attention to safety, record relevant data and take
pictures clearly
