Abstract
The invention relates to an inner liner for a plastic steel composite water heater, which is characterized in that: the inner surface of the inner liner of the metal steel water heater is coated with a layer of dense polyurea elastomer coating. The invention has simple production process, high production efficiency and low manufacturing cost, and the water is absolutely isolated with the steel inner liner, thereby resulting in that the inner liner is never eroded so as to prolong the service life of the inner liner.
Description
Technical field
The present invention relates to a kind of water heater, specifically relate to a kind of plastic-steel composite water heater inner container.
Background technology
Its inner bag of the water heater of Xiao Shouing has stainless steel inner container in the market, steel inner container inner surface enamel is arranged, the special steel alloy inner bag is arranged, have the steel inner container inner surface to apply various resin and plastics, though they all have erosion-resisting ability, all there is shortcoming and defect separately.Destroy its original component as the weld seam of stainless steel inner container because of high-temperature soldering and easily be corroded, use easy scaling etc. for a long time; Enamel inner container is subjected to easily to fall porcelain after the percussion and comes off, fall porcelain after the part easily be corroded; The various resin and plastics of steel inner container surface-coated, its production technology has and adopts rotational moulding, have to adopt blowing, also has to adopt thermal spraying.These technical process are complicated, the cost of manufacture height, and production efficiency is also lower.
Summary of the invention
In order to overcome the shortcoming that prior art exists, it is simple to have the purpose of this invention is to provide a kind of processing technology, the production efficiency height, and cost of manufacture is low, the plastic-steel composite water heater inner container of long service life.
The basic scheme that technical solution problem of the present invention is adopted is: heating the fine and close uniform thickness of water heater liner inner surface moment spraying one deck in metallic steel is polyurea elastomer coating more than the 1mm, or the solvent-free coating that derived by polyureas of spraying one deck.The tack of this coating and steel inner container is fabulous, and anti-alternating temperature-changing performance is strong, and anti-corrosion capability is stronger, can be in the medium-term and long-term use of 120 ℃ environment, and can reach more than decades service life.
The present invention compared with prior art has following advantage: 1, production technology is simple, the production efficiency height, and cost of manufacture is low.2, water and steel inner bag are definitely isolated, and make it never to be corroded, and the life-span that inner bag uses is longer.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a section of structure of the present invention.
Among Fig. 1, metallic steel heats water heater liner 1, steel flanges sheet 2, securing member 3, inner bag flange flange 4, polyurea elastomer coating 5.
The specific embodiment
Metal foil is processed into metallic steel heats water heater liner 1, heat in metallic steel and to process inner bag flange flange 4 on the water heater liner 1, metallic steel is heated water heater liner 1 and the 2 inner surface blasting treatments of steel flanges sheet, with spraying device special SPUA being sprayed on metallic steel heats water heater liner 1 inner surface and makes its instantaneous solidification, form polyurea elastomer coating 5, again with steel flanges sheet 2 spraying one deck polyurea elastomer coatings, again steel flanges sheet 2 and inner bag flange flange 4 usefulness securing members 3 are fastened on one, make its sealing water-tight.A kind of like this plastic-steel composite water heater inner container promptly completes.
Claims (2)
1. a plastic-steel composite water heater inner container is characterized in that: heat the polyurea elastomer coating (5) that water heater liner (1) inner surface applies one deck densification in metallic steel.
2. plastic-steel composite water heater inner container according to claim 1 is characterized in that: what apply at metal steel inner container inner surface is polyurea elastomer coating, or the solvent-free coating that is derived by polyureas.
