1. A tin-zinc alloy welded aluminum tank was used to heat and melt 60% tin, 35% zinc, and 5% aluminum in iron scoops and cast thin strips. Clean the oil in the cracks, grind the oxide film with an emery cloth, scrape clean with a screwdriver or a broken saw blade, and heat the aluminum parts to 300°C-40°C with a blowtorch (note that the temperature cannot be too high). Rub the electrode at the crack. When the electrode is melted, use a screwdriver to rub the molten electrode alloy at the crack to make the alloy flow into the crack, and then gradually thicken the layer.
2. Repair the tank with adhesive 1 Clean the cracks with a metal cleaner, scrape the paint, dirt, and rust there with a spatula, scrape the grooves along the cracks, and clean it again with gasoline. 2 Extrude the components A and B of XH-II adhesive in the same amount and mix it with the agricultural machinery I adhesive (about the above-mentioned adhesive to help I/3). 7 Cut two pieces of fiberglass cloth that is free of oil, is slightly larger than the grooved surface, and is coated with a layer of adhesive. 4 Place the adhesive-coated fiber cloth on both sides of the cracks for 10 minutes to 15 minutes, apply a layer of adhesive, and cure at room temperature for 25 hours.
3. Repair tank cracks with adhesive penetration method 1 Dry the water tank and drill 3 mm holes at both ends of the crack. If the cracks are long or curved, drill a hole in the center or corners and scrape the cracks with the breakage strip. , showing metallic luster. 2 Using 5O2 adhesive in two holes, riveted with 3mm aluminum rivets to seal the cracks. 7 Put the adhesive on the crack, then tap it with a hammer to make cracks in the cracks. Make the adhesive penetrate into the crack. Add 3 minutes of adhesive and tap. Repeat 2 times -4 times until the glue can't penetrate for 3 hours. - 5 hours to use.
