Quality enamel interior upgrades
In recent years, more and more consumers increasingly tend to use enamel interior material of solar products, and abandoned stainless steel liner. This means that more and more popular in the enamel interior, .
From the technical point of view, the interior is the heart of solar water heaters, and its performance affects the overall product life. As the stainless steel liner technology easy to implement, production equipment, R & D costs are lower, the vast majority of products on the market uses a stainless steel liner. However, the stainless steel liner susceptible to corrosion, easy to absorb deflated, pressure defects such as poor performance has been unable to solve. The enamel interior is durable and has a pressure, anti-corrosion, anti-smoking flat, clean water and other features, has been popular in the field of electric water heaters, solar water heaters will also upgrade the liner of choice.
From the market, the enamel interior solar market share increasing rapidly, especially in split-pressure, balcony hanging solar energy project to demonstrate superior performance of the market, but also more and more manufacturers and real estate agency\\ s attention, and thus become pressure solar project of choice. The industry believes that the future development of solar water heater industry, market pressure will become the dominant application. Stainless steel liner era is gradually during the transition to the enamel interior.
National Cheng Kung University to replace stainless steel liner enamel interior trends
It is reported that split pressurized, hot water system in the balcony wall of the tank has now been largely achieved enamel interior to replace stainless steel liner. In this area, enamel interior has more than 70% market share, the other is stainless steel, rotational molding liner. In 2010, Xi\\ an balcony wall of a real estate tender scene, nine solar companies to bid, of which seven companies enamel is used in light water tank. The top 50 companies in the industry, more than 80% of the companies and light tanks supporting the cooperation with the business. This fully shows that enamel interior tank has become a must-pressure tank.
And one for non-pressure solar water tank, it seems 90% of manufacturers are using stainless steel liner, enamel interior, although the share is very low, but substantial growth every year.
Stainless steel liner products have limitations
As the stainless steel liner technology easy to implement, production equipment, R & D costs are lower, the market for more than 90% of the product is used in stainless steel liner. Stainless steel solar energy in the \"open\" state without electric heating, the use of better, and longer product life, which is the rapid spread of solar products to advantage. However, once installed electric heating devices, especially the use of a pressure-type operation, stainless steel liner products have significant limitations.
Insiders said that the early solar industry technology is imperfect, there is no installation of electric heating devices, but with the maturity of technological innovation and increasing consumer demands, and now most solar water heaters installed electric heating equipment, pressure solar water heater much greater users.
This is equivalent to have a solar water heater electric water heater function. However, the \"heating\", \"pressure to run\" and other features of the application, the stainless steel liner has appeared in the field of electric water heaters, \"corrosive\", \"water quality perishable\" problem incidents in the solar water heater is also often, problem can not address the root causes. Once Addressing the root causes, the only way is to upgrade the tank.
The future of solar energy market must be the main battlefield of the city, which means that high-level split with the City of small solar energy will become increasingly popular in the city, split solar energy requires a certain pressure, while the cost of stainless steel more expensive, many manufacturers In order to reduce costs, make use of thin stainless steel liner, usually only 0.6 ~ 1.0mm, voltage capability down, water heater leaks more easily, directly affect the life of water heaters.
Stainless steel liner and a maximum risk – \"weld.\" Stainless steel liner biggest risks is the \"seam\", there are two on the inner ring and a straight seam weld, the weld between the cross-junction, the junction of the stainless steel of the original ingredients were seriously damaged, and easy by corrosion of chloride ions in tap water, bring to the water pollution.
Have the advantage of enamel interior
In contrast, enamel interior is the high-tech products, in the thick cylinder liner surface enamel, enamel metal material, together with seamless welding technology, can bear a greater range of temperature changes, usually in the range -60 ? ~ 450 ? temperature range, to be able to withstand sudden changes in temperature. Physical characteristics, compressive, tensile, elastic, electrical insulation, non-polluting; chemical properties, acid, alkali, high temperature resistance, water vapor, a variety of ions can not penetrate its surface are, can not effectively ensure the quality pollution.
Industry experts say the popularity of enamel interior is split solar inevitable. There is no doubt that the enamel interior adapted to the high level of foreign consumption, health and a strong sense of family and unit needs, sales soared. Most importantly, enamel interior areas of the world wide spread of solar power split, enamel interior revolution has become an irreversible trend.
