A composite material that is coated with one or several layers of enamel on the surface of the metal,and after firing,the two undergo a physical and chemical reaction to bond firmly.The old name is enamel.It has the inherent mechanical strength and processing performance of metal,and the coating has the corrosion resistance,wear resistance,heat resistance,and decoration.Enamel originated from glass decorative metal.Ancient Egypt appeared early,followed by Greece.In the 6th century,European inlaid wire enamel,cut enamel,relief enamel,translucent enamel,and painting enamel came out one after another.In the 8th century,China began to develop enamel.By the end of the 14th century,the enamel technology became more and more mature.In the middle of the 15th century,the products made during the Ming Dynasty Jingtai period were especially famous,so it was called cloisonne.In the early 19th century,Europe developed cast iron enamel,which laid the foundation for enamel to move from handicraft to daily necessities.However,due to the backward casting technology at that time,the application of cast iron enamel was restricted.In the 19th century,the development of various industries promoted the rise of steel plate enamel and opened a new era of modern enamel.From the end of the 19th century to the first half of the 20th century,the advent of various enamels with different properties,the popularization and application of steel plates and other metal materials,and the continuous updating of refractory materials,kilns,and enameling technologies accelerated the development of the enamel industry.
There are many types of enamels,which can be divided into artistic enamels,daily enamels,sanitary enamels,architectural enamels,industrial enamels,special enamels and so on.The production of enamel mainly includes glaze preparation,green body preparation,enamelling,drying,firing,inspection and other processes.For artistic enamel,daily-use enamel,sanitary enamel,architectural enamel,etc.,color decoration and assembly are required for appearance decoration and use.Industrial enamel equipment needs to be tested and then assembled.
Enamel,also known as"Folang","Falan"and"Enamel",is a transliteration of a foreign language.The word enamel originated from the name Fufu in the ancient Western Regions in the Sui and Tang Dynasties of China.At that time,the enamel inlaid crafts made by the Eastern Roman Empire and the Mediterranean coasts of West Asia were called Fufu inlay or Fulang inlay,and Fulangji,which was simplified as Fufu.When cloisonne appears,it turns to bluish and then turns to enamel.From 1918 to 1956,enamel and enamel were used synonymously.In 1956,China formulated the standards for enamel products,and enamel was changed to enamel,which was synonymous with artistic enamel.
The basic components of enamel are quartz,feldspar,borax and fluoride,which are silicate substances,which are the same as ceramic glaze,glaze,and glass(material).In ancient China,it is customary to call“glaze”attached to the surface of pottery or porcelain;“glaze”attached to building tiles;and“enamel”attached to metal surfaces.
metal enamel ware can be divided into cloisonnéenamel ware,chisel enamel ware,painted enamel ware and transparent enamel ware according to the specific processing technology in the production process.
