Information

The thermal shock test refers to placing the enamel sample in a high-temperature furnace, and after 10 to 20 minutes, quickly put it into water at 15°C to check whether the enamel is cracked or peeled off. Because each enamel manufacturer has different requirements for thermal shock resistance of products, the use of products and the size, shape, and enamel expansion coefficient of the products are different, so the temperature requirements for thermal shock will also be different, and the resistance of enamel products is different. The thermal shock capacity is related to the thickness of the enamel layer. The thinner the enamel, the stronger the thermal shock resistance. For example, the temperature of the household enamel ware (the thickness of the enamel is 150um~200um) is 185℃ in the rapid cooling test, and the chemical enamel ware with thicker enamel (Thickness is about 1mm) The measurement temperature is 100 ℃, so enamel frit manufacturers should provide suitable enamel frit according to customer requirements.

Recently, Nolifrit received an order. The customer needs a enamel that can perform 5 thermal shock tests and has good thermal shock resistance for steel plate enamel hob. After receiving the steel plate grate sample, the surface of the metal body is coated with an enamel steel plate primer, and the test sample is obtained after firing and cooling. After 5 times of hot and cold shock at 350°C, the porcelain surface is smooth and delicate, and there is no peeling phenomenon, and the performance is good. The customer is very satisfied with the quality of the enamel frit, and the two parties have successfully reached a cooperation.
