Enameling refers to the operation (glazing) of coating enamel slip or enamel powder on the metal body. It is usually divided into dry powder enamel and wet powder enamel. Different enamel methods are suitable for different enamel parts. Enamel manufacturers need to It is selected according to the metal type, shape, volume and quality of the metal body. This article briefly introduces the key points and applicable conditions of the dipping and spraying methods.
The dipping method needs to prepare the enamel slip first: determine the consistency. Determine whether there are over-dead, over-current, and dark retention phenomena in the retention. To adjust the consistency, thick powder and thin powder are generally used to mix. Thick powder can also be added directly to water or citric acid, boric acid to dethicken. To adjust fluidity, it is generally prepared by aqueous solutions of magnesium sulfate, barium chloride, sodium carbonate, potassium, potassium chloride, sodium, nitrous, sodium aluminate, ice crystals, etc. Excessive grinding and adding of everything will bring bad effects to the porcelain surface, such as boiling of the porcelain surface and poor luster, so it is necessary to be cautious in adjusting the enamel slip.
The dipping method is generally a manual operation. Electrophoresis mechanical operations are less, and manual operations generally use clamps to immerse in enamel slip, shake the bottom, hook powder, powder, rotate, swing, and shake. In short, the enamel slip is evenly distributed to wrap the embryo body. Make sure that there is no accumulation of powder, no ridge powder, and no dripping powder.
Spray enamelling method is to use compressed air to spray enamel enamel slip or enamel dry powder onto the green body. Spray enamelling can be either wet spraying or dry spraying (the only dry spraying is electrostatic spraying).
Suitable for large workpieces, large flat workpieces and bulky workpieces. Manual enamelling is difficult to complete, only spray gun spraying. Such as BBQ upper cover furnace body, subway wall panels, industrial reactors, etc.
