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:

1. 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.

2. 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.

3. 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.
