Where is the difference in quality between southern glass lining equipment and northern glass lining equipment?

At present, China’s glass enameling equipment industry enamel spray powder is mainly divided into two categories: cold spray (powder) and hot spray (powder). Most of the enameling equipment manufacturers in the north generally use cold spray technology, while most of the glass enameling equipment manufacturers in the south use hot spray technology.

1. At present, China’s glass enameling equipment industry enamel spray powder is mainly divided into two categories: cold spray (powder) and hot spray (powder). Most of the enameling equipment manufacturers in the north generally use cold spray technology, while most of the glass enameling equipment manufacturers in the south use hot spray technology. The following is a brief discussion of the difference between hot and cold spray powder and the advantages and disadvantages.

2. The biggest advantage of hot spraying technology in the south is that the cost is very low, often enameling process two to three times on the product. But the disadvantage is that the quality is not stable, the product is very easy to occur in the inferior environment, thus causing more losses to the user.

3. North of the cold spray technology is the biggest advantage of product quality and stability, but the equipment enameling process should be in six to seven times or so, so the cost is too high. You know, each additional enameling, have to go through thousands of degrees of high temperature firing, visible cost difference. The quality of enameling equipment in addition to the enamel is good or bad, but also with the enameling equipment selected spraying technology has an important relationship. Simply put, cold spraying is enameling equipment in the cooling of the blank at room temperature state of the powder spraying operations, thermal spraying is enameling equipment in the blank is not completely cooled that can work under the state of the powder spraying operations. Cold spraying to facilitate the workers on the billet and porcelain powder grinding and refinement of the operation again and again, and porcelain powder in the natural drying of water, this technology under the operation of the thin layer of porcelain (the effective thickness of the large), the number of times the firing, the cost is high; thermal spraying is in the enameling equipment is not completely cooled on the operation, the enamel in the water in the powder through the non-cooling steel forced drying, so the cycle of fast, high production equipment, but also because of the temperature problem, thermal spraying powder Can only be covered for each production defects in the operation, can not be fine grinding, so its enameling equipment porcelain layer is thicker, the cost is relatively inexpensive.

4. It can be seen that the thermal spray technology, although the production of fast, thick layer of porcelain (enameling equipment is not the thicker the better), but because of high-temperature operations are prone to produce dark bubbles, porcelain thick and uneven, easy to shed the whole piece of porcelain surface. The cold spraying although high cost, the production volume can not be expanded, but from the user’s point of view, the production equipment is guaranteed, the porcelain layer is uniform (in line with international standards).
