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 are the causes and solutions of the enamel orange peel defect?

The orange peel-like irregular wrinkles on the surface of the porcelain enamel layer are called orange peel wrinkles (orange peel wrinkles). Orange peel wrinkles are a kind of defects on the enamel surface, which directly affect the appearance quality of enamel products. Smooth and smooth, no defects such as pores, de-porcelain, line spots and so on. There are many reasons for orange peel wrinkles, generally enamel frit or enamel slurry. If your product has orange peel wrinkles, it can be analyzed from the following reasons: The enamel frit used has high surface tension and high viscosity; The enamel frit slurry is stored for too long, and the coarse grains sink; The enamel slurry particles are too coarse and the enamel is too thick; The temperature of the enamel firing furnace is too high; Uneven dissolution during firing; Excessive air pressure during enamel spraying. When encountering orange peel wrinkles, it should be noted that the enamel slurry should not be stored for too long and the furnace temperature for firing the enamel cover coat should not be too high. If it is daily enamel, pay attention to the lower surface tension in the choice of cover coat.

How do you enamel a wood burning stove?

Some wood burning stoves are made of enameled steel, but the enamel is applied at the factory. The enamel is actually a form of glass, which is applied to the steel as a powder and then melted and fused on in an oven or kiln at a very high temperature. It is not the kind of thing that can be done in the home.

Are teeth brittle?

Healthy teeth should NOT be brittle. Instead, they should have healthy enamel. A thick enamel makes teeth strong and bright white. Teeth without enough enamel look off-white or gray, and can become brittle. This lack of enough enamel can lead to tooth weakness, cracking, and breakage.

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.
