For Enamel Defects, Nolifrit Have Something To Say
The quality of enamel frit determines the quality and physical and chemical properties of enamel products, including adherence, acid and alkali resistance, temperature shock resistance and so on. There are many reasons for the defects of physical and chemical properties of enamel products, which are due to the many production links of enamel products and the influence factors involved are also diverse. The main purpose of this article is to explain the reason of the physical and chemical property defects of enamel products.
There are three reasons for the formation of poor adherence, as follows:
1, The quality of the ground coat frit is poor.
2, The quality of milling additives barium molybdate and antimony oxide is poor.
3, The ground coat is coated too thin, the firing temperature is too high or too low, the ground coat is burnt or not completely fired.
There are four reasons for poor acid resistance, as follows:
1, Cover coat is not completely melted.
2, Cover coat has poor acid resistance.
3, Excessive milling additives added.
4, Cover coat is fired inadequately.
There are five reasons for poor impact resistance, as follows:
1, The strength of the metal substrate is insufficient.
2, There are too many milling additives added.
3, The ground coat is sprayed too thick, burning is insufficient.
4, The elasticity of the enamel frit is poor.
5, The adherence of the product is poor.
Temperature shock resistance.
There are four reasons for the poor performance of temperature shock resistance, as follows:
1, The cover coat layer is too thick.
2, Insufficient firing.
3, The adherence of the product is poor.
4, Direct-on matte black enamel frit quality is poor.
Through the analysis of the causes of these defects, enamel products manufacturers can improve the operation, select high-quality enamel frit, so as to eventually improve the quality of enamel products, to meet the requirements of customers to achieve better economic benefits. It is very important to choose an excellent enamel material supplier. The reliable enamel glaze manufacturer can help the enamel factory develop better. Nolifrit is a global professional enamel glaze production company. The annual production of enamel glaze 20,000 tons, enamel powder 10,000 tons, welcome customers to inquire.
