Frac balls are inserted into wells to build up pressure in the ground. WINGOIL frac ball can be used as a test for the HCL Acid Resistance Test. 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
