What is the color matching in ball milling of enamel frit?
Enamel color matching is a technical work that needs to be done by professional technicians with the help of colorimeters. It not only needs to master the relevant knowledge of enamel pigment, enamel frit and enamel firing process, but also establishes a database of color and chromaticity values of various pigments in the basic enamel. To adjust the color of enamel, first determine which basic enamel to use according to the lightness value of the color sample, and then search and select the pigment with a similar chromaticity value in the database built according to the chromaticity value of the color sample. After repeated trial matching, proofing, comparison and adjustment, the final enamel slurry ratio, enamelling, firing, porcelain layer thickness and other related process parameters are recorded in detail as a basis for guiding production operations. The variety of enamel pigments is quite limited, and most enamel colors are formulated from two or more enamel pigments. Enamel production factories and enamel manufacturers can purchase or customize colors from enamel pigment suppliers according to their own needs. Common colors include light pink, golden yellow, lemon yellow, sky blue, fruit green, dark gray, etc.
Dry and Wet Powder Enamel, Which Cost Higher?
What kind of production process is used in enamel directly determines the level and quality of the product. The enamel factory will choose the enamel process according to the metal type, shape, and volume quality of the green body. Generally, it is divided into two categories: wet enamel coating and dry enamel coating. So which one costs more, dry powder enamel or wet powder enamel? What are the advantages and disadvantages? How to choose an enamel factory? After reading this article, I believe you will have the answer. (1) Dry powder enamel Dry powder enamel is the abbreviation of electrostatic dry powder automatic adsorption process, also known as electrostatic enamel. The enamel powder is electrostatically sprayed, adsorbed on the metal surface, and then sintered at a high temperature above 800 °C, so that the expansion coefficient of the enamel powder and the steel plate can be nearly the same. The biggest advantage of dry electrostatic enamel coating is that the utilization rate of enamel can reach 97%~98%. The enamel dry powder can be used directly without grinding the enamel slurry. high. The service life of dry powder enamel is 2~3 times that of ordinary wet enamel, but the cost is also 2 times. The equipment of dry powder enamel is expensive and suitable for powerful enamel manufacturers. Dry powder enamel is a high-quality advanced process, generally used in enamel ovens, water heaters, microwave ovens, washing machines and other household appliances, and gradually extended to kitchen utensils and wall panels. (2) Wet enamel Enamel powder and other raw materials are ground into enamel slurry with water, and then enamel is applied to the surface of the casting and then sintered at high temperature. Because the liquid spraying process is not like electrostatic spraying, it is easy to flow unevenly, and it will cause enamel defects such as blasting in case of shocks. However, the investment in equipment is small, the price is cheap, and the production is simple. The enamel products made by this process are often used in enamel products such as daily necessities and decorations.
Why is that enamel has no possibility of self-repair?
Enamel has no possibility of self-repair because it is an acellular tissue, meaning it lacks living cells that can regenerate or repair damaged areas. Additionally, enamel is primarily composed of inorganic minerals, mainly hydroxyapatite, which do not have the biological mechanisms necessary for regeneration. Once enamel is eroded or damaged, the body cannot produce new enamel, making it crucial to maintain oral hygiene and seek dental care to prevent further damage.
