There are many ways to determine the formula of enamel enamel, and the following two methods are commonly used.

1. Test adjustment method

The procedure of determining the formula of enamel and enamel by the test adjustment method is as follows: ① Determine the type of enamel. ② Design the composition system according to the required physical and chemical properties. ③According to the composition system, determine the use varieties of various raw materials. ④ Determine the dosage of various raw materials. ⑤ Carry out batching, melting, ball milling and enamel firing tests, measure the performance data of each enamel, and do further adjustment tests until the performance requirements of the enamel are met. ⑥ Calculate the final formula into chemical composition. Using this method to determine the enamel frit formula requires the designer to have rich practical experience.

2. Composition calculation method

The composition calculation method is based on the chemical composition of the enamel frit designed according to the performance requirements of the formula, and then the quantitative ratio of various raw materials is obtained with reference to the theoretical calculation method of the performance of the enamel. There may be multiple schemes to calculate the ratio of raw materials by the designed chemical composition, and it is necessary to adopt the orthogonal test and optimization method to optimize and adjust to obtain the best chemical composition ratio and process of enamel and enamel. The advantages of the composition calculation method are: ①Reliable performance, when designing the composition, the physical and chemical properties of the formula can be predicted according to the addition method, and adjusted in time. ② The test is carried out after the design components meet the performance requirements, so the number of tests is small, the time is short, and the cost is low. To determine the enamel formula, in addition to the above two methods, the electronic computer can also be used to preliminarily determine the chemical formula of the enamel frit.
