Making method of porcelain enamel radiator

Abstract

The invention discloses a making method of a porcelain enamel radiator, which is characterized in that a steel pipe is used as a parent material; after being sprayed and coated with enamel, the innerpipe wall and the outer pipe wall of the steel pipe are sintered at high temperature to form the porcelain enamel radiator. The concrete technical process is as follows: washing, preparing base enameland surface enamel, coating the base enamel, drying, coating the surface enamel, sintering and cooling to make the product. The making method is suitable for producing porcelain enamel radiators in batch and has the advantages of simplicity, practicality and high production efficiency. A produced porcelain enamel pipe resists acid and alkali, and the radiators with different colors for appearances are produced, thereby solving the aging and deteriorating problem of the radiators; and the service life of the product is prolonged to 3 to 5 times of that of an ordinary radiator. The porcelain enamel radiator is suitably used for office buildings, schools, recreation places and families.

Description

Technical field [0001] The invention relates to a production method of inner enamel, outer enamel, and inner and outer enamel radiators. Background technique [0002] In the prior art, the pipe fitting structure of office buildings and residential buildings usually uses steel pipes or cast iron pipes, and the outer surface of the pipe fittings is usually painted with an anti-rust layer. However, the tubular cavity cannot be sprayed, and there are shortcomings, and it encounters water during use. The paint layer on the outer surface of the rear pipe is easy to age, peel off, and the inner surface will quickly rust, which not only affects the appearance, but also pollutes the water quality, but also easily blocks the pipeline and has a short life. Summary of the invention [0003] The purpose of the present invention overcomes the disadvantages of the above-mentioned prior art that the paint on the outer surface of the pipe fitting is easy to be aged and peeled off after encounterin...
