enamel spray prospects
Universal situation: At present, whether domestic or international market stainless steel liner is almost extinct; as control period by the popularity of stainless steel inner liner to enhance the period over enamel, stainless steel liner so the market share is still large. Some solar companies have tried to produce enamel interior, but the enamel interior, investment, output short-term benefit is not obvious, even to fail, many companies do not labor and return.
Construction of a conservation advocate at the national, energy-efficient environment, China\\ s solar water heater industry, gradually the rapid development of the road, basically formed a relatively complete industrial system, to enter the international market situation has become more evident.
\"Liner\" is the heart of , their characteristics affect the overall life of the product. According to the HC surface network Xiaobian understand, easy to implement as stainless steel liner technology, production equipment, R & D costs are lower, the vast majority of products on the market uses a stainless steel liner. However, the industry\\ s technology level restrictions, stainless steel liner susceptible to corrosion, easy to absorb deflated, pressure defects such as poor performance has been unable to solve. The enamel interior with durable pressure, anti-corrosion, anti-smoking flat, clean water and other features, has been popular in the field of electric water heaters, solar interior is also upgraded to provide a reference and reference.
A solar water heater to reveal the history of development
Tank anti-corrosion technology, for the water heater is a very important. Water heater tank is a history of anti-corrosion technology\\ s development. We went into the mall counter electric water heater, see the \"Titanium Liner,\" \"Kim Kyu-liner\", \"blue magic liner\", \"enamel interior,\" and so many inner names. In fact, the interior is basically the use of enamel process, just to reflect a selling point of differentiation, from the name of the manufacturers just not the same. So far, the water heater from the original galvanized steel liner, to the stainless steel liner, to the enamel interior has undergone a total of three generations of history.
Water heater through the course of development of three generations
? 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 situation: At present, whether domestic or international market stainless steel liner is almost extinct; as solar heat control period by the popularity of stainless steel inner liner to enhance the period over enamel, stainless steel liner so the market share 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 ? 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: the rapid development of domestic and foreign markets, consumers and strong sense of identity, 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. One course of development of the electric water heater longer, with a few decades or even centuries. At present, whether domestic or international market, stainless steel liner has virtually disappeared, enamel interior products universal. Stage of development of solar water heaters due to the restrictions, the vast majority of enterprises are using the stainless steel liner in the application of non-pressure solar water heater has some advantages, larger market share.
Enamel interior are high-tech products. Through the thick steel-plated enamel surface glaze, can bear a greater range of temperature, usually -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, water vapor, a variety of ions can not penetrate its surface are, can not effectively ensure the quality pollution.
The past two years, the solar interior enamel rapid increase market share, especially in the split pressurized solar project market has shown outstanding performance, more and more manufacturers and real estate agency in importance as the product of choice for the project under pressure. The future development of solar water heater industry, market pressure will become the dominant application. As the industry growth restriction, the current popularity of stainless steel liner industry to phase and phase enamel interior needed to transition.
