——What to do if lines appear on the enamel surface?

The string lines on the enamel surface refer to the small, elongated lines that appear on the enamel surface, and their shape is similar to lines. Although it does not destroy the integrity of the porcelain layer, it greatly damages the appearance of the product. Once the enamel manufacturer discovers that the product has string lines, it needs to find out the cause immediately and take solutions to avoid affecting the overall quality of the enamel product and increasing the manufacturer's production costs.

As a manufacturer of enamel frits and enamel pigments, Nolifrit has a professional technical team to provide customers with solutions. Therefore, after a customer recently faced a problem with pull lines, the Nolifrit technical team responded quickly and effectively solved the defect. , the following is a sharing about the solution to the drawing lines on the enamel surface. Welcome enamel partners to discuss and communicate with us:

First, adjusting the thickness of the enamel ground coat is key. The thickness of the ground coat is too thick or too thin, which may lead to the appearance of pull lines. Therefore, we need to precisely control the thickness of the ground coat and strive to be thin and even. Making the ground coat thin and controlling the thickness appropriately can effectively reduce the probability of line defects.

Second, ensuring that the enamel ground coat is burned through is also an important measure to solve the problem of pull lines. Firing temperature is a key factor affecting the degree of firing of the ground coat. Appropriately increasing the firing temperature can melt and solidify the ground coat more fully and reduce the occurrence of string lines. At the same time, in order to avoid scorching due to excessive temperature, we can add an appropriate amount of high-temperature resistant materials such as quartz to the ingredients to improve the high-temperature resistance of the ground coat.

Third, the thickness of the cover coat will also affect the formation of draw lines. Properly grinding the cover coat can increase the bonding force between the cover coat and the ground coat, improve the overall stability of the enamel layer, and thereby reduce the occurrence of pull lines. Of course, the thickness of the cover coat also needs to be adjusted according to the specific situation to avoid excessive grinding that affects the appearance quality of the product.

The above is the solution shared by Nolifrit regarding the drawing lines on the enamel surface. If you also have related questions, please feel free to contact us!
