What should enamel factories pay attention to when purchasing enamel frit?
Enamel frit has a great influence on the quality of enamel products, including acid resistance, alkali resistance, gloss, impact resistance and other physical and chemical properties of enamel finished products. Therefore, enamel manufacturers should pay special attention to the following three points when purchasing enamel frit: Compare the properties of the enamel. Different products have different quality requirements for enamel frit. First of all, according to the characteristics of their own products, understand the properties of enamel frit. For example, for enamel ground coat, consider whether the thickness of the ground coat is conducive to the discharge of gas; Whether the firing temperature of the ground coat is appropriate, and whether it can reduce the generation of gas during firing; the enamel cover coat should consider the opacity and have a good surface covering power; the surface tension and viscosity of the cover coat can ensure the formation of Smooth and smooth porcelain surface...and other properties such as acid and alkali resistance. Are there any mature formulas and technical solutions? The determination process of the enamel formula is very complicated. A set of mature formula needs to continuously carry out batching, melting, ball milling, and enamel tests, measure the performance test of each enamel, and continuously adjust the test, so as to finally achieve the target performance requirements. Therefore, if the enamel manufacturer chooses the enamel frit, the supplier can have the corresponding mature formula, on the one hand, it can ensure the qualified rate of the product and reduce the occurrence of defects, on the other hand, it also reduces the cost of the enamel manufacturer and reduces the process. Sample test. When purchasing enamel frit, the enamel factory fully communicates with the supplier in advance. If there is a favorite product, you can ask the other party to send a sample, and then place an order after passing the test, which can effectively avoid some unnecessary after-sales links and save costs.

What is the role of enamel edge coating?
Enamel edge coating is a type of ceramic glaze applied to the edges of enamel products. Depending on its purpose and color, edge coating can be classified into base edge coating, white edge coating, colored edge coating, and more. This article will detail the functions of enamel edge coating and the considerations for enamel manufacturers when procuring the appropriate edge coating. 1.Functions of Enamel Edge Coating Preventing Edge Defects The edges of enamel products experience concentrated stress, making them prone to defects. Enamel edge coating has a suitable expansion coefficient that can effectively accommodate the stress of the casting, reducing the occurrence of edge defects. Adapting to Firing Variations During the firing and cooling processes, the heat absorption and dissipation of the edges differ from other parts of the casting. Ordinary base and surface glazes may struggle to adapt to these variations, leading to defects. Enamel edge coating has a specialized formula that meets the demands of the firing process, preventing defects. Enhancing Product Quality Enamel edge coating can fill in defects at the edges of castings, making the surface smoother and more aesthetically pleasing. Additionally, the color and texture of the edge coating can match the surface glaze, providing a cohesive visual effect for the entire product. How Enamel Manufacturers Can Procure Suitable Enamel Edge Coating For enamel manufacturers, procuring the right enamel edge coating is crucial. On one hand, it is essential to ensure the edge coating is of reliable quality and meets the product's usage requirements. On the other hand, manufacturers need to select the appropriate type and color of edge coating based on the specific conditions of the product and the production process. This requires manufacturers to focus not only on the performance indicators of the edge coating during procurement but also to communicate thoroughly with suppliers to ensure that the chosen edge coating aligns with their production processes.
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.
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.
What is a low-temperature enamel coating?
