How To Judge The Firing of Enamel Products?
The firing of enamel products is a very important part of the enamel process. During the firing process, the various firing technical parameters and operating points that the operators of the enamel factory must strictly follow, and strictly follow the reasonable process production and implementation, is conducive to improving the enamel production. product quality. So how to judge the time and firing effect of enamel products? The firing temperature of enamel products is set with a furnace temperature gauge, and the firing time is controlled by a stopwatch. After the firing, relevant instruments and equipment are used to detect the gloss or adhesion strength of enamel products to judge the firing quality of enamel products. If it is fired in a batch muffle furnace, it can generally be judged by visual inspection. Put the dry powder blank into the furnace, under the contrast of the bright red furnace wall, the powder blank shows a dark color, and when the temperature rises, it will turn into a light and color similar to the furnace wall, indicating that the temperature of the blank at this time is the same as the furnace wall. The temperature is close, but the internal temperature of the iron billet may not have reached it, and it will take a while to be fired. As for how long it takes to burn, it depends on the experience of the operator, which is related to the wall thickness and material of the enamel billet. If it is a continuous firing furnace, it is adjusted by setting the furnace temperature table and the linear speed of the transmission chain (or the speed of the driving wheel), and the temperature and speed are the product's adhesion, porcelain surface gloss and smoothness by the on-site technical supervisor. The casting adjustment is determined after multiple inspections such as the degree and so on.

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.

How do I do steel enamel pre-treatment?
In the enamel manufacturing industry, metal pretreatment is a crucial process, which directly affects the quality of the enamel finished product. Whether it is an enameled steel plate or a cast iron billet, pretreatment is required. It is worth mentioning that stainless steel enamel also requires stainless steel pretreatment. Stainless steel enamel needs to be sandblasted to roughen the surface of the body and improve the close adhesion between the enamel layer and the enamel layer. A customer once tried to make stainless steel enamel by himself, but the adhesion of the finished product was not good. However, both the enamel manufacturing process and the quality of the enamel frit and stainless steel were confirmed to be correct. After in-depth investigation and testing by our technical staff, we found that the cause was the lack of metal pretreatment. After sandblasting pretreatment, the adhesion of the enamel finished stainless steel products is significantly improved, meeting the customer's expectations. Taking steel plate enamel as an example, the metal pretreatment process is equally rigorous. First, the steel plate workpiece needs to be soaked in a degreasing liquid at 55 to 65 degrees Celsius for 15 to 30 minutes to completely remove oil stains on the surface. Next, the remaining liquid on the surface of the steel plate is thoroughly cleaned by water washing to ensure that no impurities remain. Then comes the rust removal process, where the steel plate is soaked in a rust removal solution at 50~60°C for 10~15 minutes (the specific time depends on the rust on the surface of the steel plate). This step is to remove rust and oxides from the surface of the steel plate and ensure that the enamel layer can be evenly and firmly attached to the metal substrate. After rust removal, wash again to ensure the surface of the steel plate is clean. Finally, the steel plate is neutralized to ensure that every part of the steel plate workpiece is immersed in the neutralizing solution to neutralize the remaining acid and alkali substances and prevent adverse effects on the subsequent enamel layer. After the neutralization is completed, the steel plate workpiece is naturally air-dried to prepare for the subsequent enameling process. Although pre-treating enameled metal may seem simple, every step is crucial. It not only improves the quality of finished enamel products, but also extends the service life of the product. Therefore, as an enamel manufacturer, you should attach great importance to the metal pretreatment process and ensure that every step is operated in strict accordance with standards.
