Galvanized sheets of iron, steel , parts and fittings for much longer defy rust. Wooden parts held together with galvanized fasteners, less destroyed.
On sale are very rare fasteners coated with zinc, cadmium, etc. At home, if there is a muffle furnace or a furnace, it is easy to cover small parts in zinc, iron sheets and fasteners.
Hot galvanizing , with which you can get to the sheets of iron, steel , various details and fastening relatively thick and solid zinc film is carried out according to the following technologies:
1. In a suitable container, place the steel materials for galvanizing
2. Pour the working mixture consisting of 75% of the total weight of the mixture of zinc powder and 25% pure finely sifted sand
Steel and metal parts, such as screws and nuts, degreased with acetone or gasoline for lighters. Then put 1-1.5 min sulfuric (50 g/l) or salt (40g/L) acid. Rinse with water and dried.
Screws and nuts and mix for working galvanizing put on weight in the ratio 1: 1 and mix thoroughly. Then close the lid and the jar was placed in a muffle furnace or forge. Operating temperature of 400-500 degrees Celsius. Treatment period up to 10 hours.
When galvanizing relatively large pieces such as sheets of iron, steel, etc., come a little differently: at the bottom of the container poured a layer of the working masses in height of 4-5 mm and placed on her part and on top even poured a layer of richness. Then, cover the jar and do the same as for galvanizing fasteners.
