Description

Enamel pot enamel layer and electroplated layer treatment process

Technical Field

The invention relates to the field of cookers, in particular to a treatment process of an enamel pot enamel layer and an electroplated layer.

Background

Enamel is a composite material in which an inorganic vitreous material is fused to a base metal and is firmly bonded to the metal. The enamel has the inherent mechanical strength and processing property of metal, and the coating has the corrosion resistance, wear resistance, heat resistance, no toxicity and decorative property. Enamel pots are sought after for their aesthetic appearance, portability, and heat resistance. The enamel pot is generally white, and the glaze solvent used by the white enamel is silicon oxide, aluminum oxide, manganese oxide, potassium oxide and sodium oxide, and is lead-free, so that the enamel pot has no aluminum poisoning risk. Because of the stable chemical property of the enamel pot, the enamel pot can store light acid and alkaline foods.

CN201811357140.9 discloses an enamel pan without edge covering and a manufacturing method thereof, wherein the edge covering is carried out on the pan opening, and the edge covering is wrapped with a ground coat and an outer glaze coating to protect the edge, or the straight edge obtained by the edge cutting of the pan opening is polished and electroplated to wrap the edge with an electroplating protective layer, thereby the installation step of sleeving a stainless steel ring on the edge of the pan opening in the traditional process is omitted, the water accumulation in the stainless steel ring is prevented, the problem that the stainless steel ring falls off after long-time use is avoided, and the condition that the pan opening is rusted or easily bruised after the steel ring falls off is avoided. However, the enamel product usually has a turned-over edge which is directly turned outwards, the area of the edge of the turn-over edge is small, enamel on the turned-over edge easily falls off due to collision in the use process, and therefore in the use process, the edge of the turned-over edge can be rusted due to the exposure of the metal substrate, and the attractiveness of the ceramic product is affected.

CN201110415172.1 discloses a pan that enamel and brush plating combine, including the pan main part, the pan main part includes the metal level, is equipped with the enamel layer outside the metal level, and the oral area border department of pan main part is equipped with the electric brush cladding material that adopts the electric brush plating technology to make. However, the pot still has the problems that the boundary between the enamel layer and the electroplated layer at the mouth part is not beautiful and the corrosion resistance is poor, and the pot mouth still can generate rust, which seriously affects the beauty of the pot.

Referring to fig. 1 and 2, the invention discloses an enamel pot, which comprises a pot body 1 and a flanging 2, wherein the inner surface and the outer surface of the pot body 1 are wrapped with enamel layers 4, the upper surface and the lower surface of the flanging 2 are covered with electroplated layers 5, a first annular bulge 6 is arranged at the position, close to the inner surface of the pot body 1, of the flanging 2, a second annular bulge 8 is arranged at the position, close to the outer surface of the pot body 1, of the flanging 2, the electroplated layers 5 and the enamel layers 4 are distributed on two sides of the first annular bulge 6, and the electroplated layers 5 and the enamel layers 4 are distributed on two sides of the second annular bulge 8. The boundary of the electroplated layer and the enamel layer is determined by arranging the first annular bulge 6 and the second annular bulge 8, so that the height of the boundary is ensured to be consistent, the interface is neat, the attractiveness of the boundary of the electroplated layer and the enamel layer is greatly improved, and the height and the position of the boundary are prevented from being determined by a traditional manual polishing mode. In addition, it is found that before the conventional flanging is electroplated, the enamel at the periphery of the boundary is easy to be damaged to form a tiny crack in the grinding and polishing process of the boundary, so that a tiny crack is formed at the boundary of an electroplated layer and an enamel layer, the bonding strength of a coating at the boundary is reduced, and the flanging is easy to corrode and rust in the using process. The first annular bulge and the second annular bulge in the application can overcome the problems, and because the application polishes the first annular bulge and the second annular bulge, the enamel layer at the highest point of the first annular bulge and the second annular bulge is thinnest and cannot cause cracks.

In order to further strengthen the bonding strength of the enamel layer at the boundary and avoid causing cracks in the polishing process, the first annular groove 7 and the second annular groove 9 are respectively arranged in the direction of the first annular bulge and the second annular bulge close to the pot body. The first annular groove and the second annular groove are arranged, so that the thickness of an enamel layer at a boundary can be increased, and the groove structure is favorable for improving the bonding strength of the enamel layer and the pot body.

The height H1 of the first annular protrusion is 0.5-0.8mm, the height H2 of the second annular protrusion is 0.3-0.5mm, the depth H1 of the first annular groove is 0.3-0.5mm, and the height H2 of the second annular groove is 0.5-0.8 mm. The pot body is of a cast iron structure.

The manufacturing steps are as follows:

1. carrying out polishing, oil removing and rust preventing processes on the pot body 1;

2. performing ground coat treatment on the inner surface and the outer surface of the pot body 1, discharging and cooling, wherein the ground coat amount is 300g/m2, drying at 150 ℃, performing 850-890-degree high-temperature sintering on the pot body 1 to form a ground coat coating with the thickness of 250um,

3. and (3) glazing the outer surface of the pot body 1, drying at 150 ℃, and sintering the pot body 1 at 850-.

4. And scrubbing, grinding and polishing the edge of the flanging 2, and electroplating the flanging 2 by taking the first annular bulge and the second annular bulge as boundaries.
