Henan Qinyang buried fire water tank flow

If the stainless steel fire water tank leaks, how should we deal with it? I summarized several points for you to understand together.

1. Repair the box with adhesive

When the stainless steel water tank leaks, we can clean the crack with metal cleaner, scrape off the paint, dirt and rust with a scraper, shovel out the groove along the crack, and then clean it repeatedly with gasoline.

In addition, cut two pieces of oil-free glass fiber cloth with slightly larger groove surface, and apply a layer of adhesive on the top. Stick the fiber cloth with adhesive on both sides of the crack After 10-15 minutes, apply another layer of adhesive and dry it at room temperature for 25 hours before use.

2. Repair the aluminum water tank with tin zinc aluminum alloy

In addition to repairing the box with adhesive 6o% tin, 35% zinc and 5% aluminum are heated and melted in iron spoon and other equipment to build a long thin electrode.

Clean the oil stain at the crack, polish the air oxide film with sandpaper, scrape it off with a screwdriver or a saw blade, heat the aluminum part with an air furnace, and rub the welding rod at the crack. When the welding rod melts, use a screwdriver to rub the molten electrode alloy at the crack, so that the alloy can be injected into the crack, and then gradually thicken the welding layer.

3. Repair box cracks with adhesive penetration method

Dry the water tank and drill on both sides of the crack For 3mm holes, if the crack is long or bent, another hole can be drilled in the middle or at the corner. Scrape the crack with a broken strip to expose the metal texture. Use 502 adhesive to drop into the two holes, rivet with 3mm aluminum rivets, seal the crack, drop the adhesive on the crack, and then use a hammer to measure and knock the crack twice to make the adhesive penetrate into the crack. After 30 minutes, add adhesive and knock again, Repeat for 2~4 times until the glue can not penetrate. It can be used after 3~5 hours.
