The course of development of
As the world\\ s largest manufacturer of and consumer, China\\ s solar energy industry with annual capacity of more than 35% annually. The most traditional solar water heater is a stainless steel liner, mainly due to the reasons for the industry\\ s technology level, stainless steel liner of the defects has not been solved. According to the relevant departments test showed that the corrosion of stainless steel liner in hot water after a large number of ions harmful to human health, long used to bathing, washing vegetables, washing dishes, etc. will adversely affect users, especially on the body resistance is weak, people prone to allergies skin more obvious. With the gradual increase consumer awareness of health, with \"clean water\" performance of the water heater in the field of solar energy promotion is increasing.
Water heater History
When we are walking into a store counter water heater, see the \"net blue liner\", \"Titanium Liner,\" \"Kim Kyu-liner\", and other items so that consumers get confused by the water heater, you could not tell. In fact, so far, water heater tank had experienced three generations of the development process, in which the electric water heater of the development process longer, have decades of history, the solar water heater started late, only 10 years of history.
? The first generation of liner: zinc, copper liner
Features: thin protective layer, no rust treatment, easy to scale, short life.
Universal situation: basically disappeared.
? second generation tank: stainless steel liner
Features: good material, not rusty, but the biggest risk is \"weld.\" 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 susceptible to corrosion of chloride ions in tap water, bring to the water pollution.
Universal conditions: electric water heaters have been represented by Haier, had a certain market, but from 2006, Haier has also eliminated the stainless steel liner, full use of enamel interior. At present, whether domestic or international market stainless steel liner is almost extinct; solar water heaters in the Mitsubishi three workers, Emperor Ming, Qinghua Sun and other companies represented. As the control period by the popularity of stainless steel liner to enhance the period of excessive enamel interior, so the stainless steel liner of the market is still large.
? the third generation liner: enamel interior
Features: high-tech products, cylinder liner surface in thick enamel, metal or ceramic materials, mostly silicon compounds, together with seamless welding technology, can bear a greater range of temperature, usually -60 ~ +450 ? of 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, water vapor, a variety of ions can not penetrate its surface are, can not effectively ensure the quality pollution.
Universal conditions: electric water heaters, AO Smith, an international brand with Kim Kyu-liner, Ariston titanium liner, represented the brand in the domestic interior light blue magic, blue liner Mitsubishi three represented the net work, at home and abroad occupy most of the market share; solar water heaters, to light blue magic liner, net blue Mitsubishi three workers, represented by water-based liner, the rapid development of the market and strong consumer identification with the most growth potential.
This shows that enamel interior, electric water heater in the birth of the field is a long process. From galvanized steel liner, to the stainless steel liner, which developed into enamel interior. At present, domestic and overseas markets, enamel interior, have switched to become a mainstream product. Electric water heater solar water heater started later than some, also went through this process, now popular term by the stainless steel inner liner to the enamel transition period, and net water blue enamel interior liner technology for the solar peak representative.
Solar technology is imperfect early development of the industry, there is no installation of electric heating devices, but with the maturity of technological innovation and consumer demands increased, most solar water heaters are now installed electric heating equipment, solar water heaters that have a water heater on the function . However, with this complementary technology to the optical, electric water heater stainless steel liner in the field of \"corrosive\", \"water quality perishable\" problem incidents in the solar water heater is also often appear, to some extent caused by the consumer questioned the entire solar industry. So, with \"clean water, health and durable\" enamel interior features full extension in the solar industry is inevitable.
Now the vast majority of solar water heaters electric water heater has not been the product development stage, not dedicated to the development of enamel interior, water-based enamel liner technology with very few companies. Relative to the normal enamel interior, net blue water-based enamel liner material used is high-grade enamel, enamel by two 900 ? high temperature baking, the bottom plate of mutual penetration of the glaze and the integration of steel and water is not guaranteed will contact, can effectively eliminate the ordinary enamel interior was often blistering, peeling, uneven enamel-plated case, the surface enamel can prevent oil, at the end of the glaze can prevent rust.
