Embodiment 1
[0030] A preparation method of an acrylamide-bentonite capsule loaded with a corrosion inhibitor, comprising the following steps:
[0031] Step 1. In parts by weight, take 8 parts of chitosan powder and place it in an oven for drying, sieve to remove impurities, then add 50 parts of deionized water and 2 parts of liquid corrosion inhibitor, and continuously stir at 80°C for 50 minutes. Obtain the mixture solution, dry and concentrate the mixture solution to 35% of the original volume in an oven to obtain a viscous mixture, inject the viscous mixture into a spherical container through a syringe, dry and solidify into a spherical shape, and obtain the corrosion inhibitor; the chitosan The molecular weight of the powder is 100,000; the liquid corrosion inhibitor is corrosion inhibitor FJH-08;
[0032] Step 2. Prepare an aqueous solution of acrylamide. In parts by weight, add 0.3 parts of a crosslinking agent, 0.005 parts of an initiator and 15 parts of bentonite to 50 parts of an...
