The cladding of a good solar water heater should be made of food grade SUS304/2B stainless steel plate. Most manufacturers in the market now choose this material...
The current price of SUS304 should. be about 40,000 per ton. There are many stainless steel plates: 201, 202, 304, 304L, 316 and so on. The most commonly used are 304 and 202. Difference:
304# and 202# are both American standard grades, 304 is 0Cr18Ni9, 202shi 1Cr18Nn8Ni5N
They are all steel Austenitic stainless steel, 202 uses Mn and N to replace part of the nickel, thus obtaining good mechanical properties and corrosion resistance. This is a new type of nickel-saving stainless steel. Its room temperature strength is higher than that of 304, and it has good oxidation resistance and medium temperature strength below 800 degres. .......
What type of material is qualified for the inner lining of a solar water tank?
Among the many brands of water heaters, each manufacturer chooses the interior lining of the water heater. Therefore, when consumers purchase water heater brands, in addition to comparing and identifying in terms of price, performance, etc., they should also pay close attention to identifying the coating types of different water heater brands, as this determines the safety, insulation performance and usability of the water heater. The key to longevity.
The protective zinc layer of the galvanized sheet covering measures only 0.06 mm. The coating is not rust-proof after forming, so it is easy to rust. It has a short lifespan and will not be used. by general traders.
Stainless steel coating: this type of coating is made ofgood material and is not easy to rust, but welds leak easily; it cannot meet the requirements of multi-head water supply, and this is now the case. used by general water heater manufacturers.
Jingui Coating: This coating is made of high quality steel and special high temperature resistant silicon. It is particularly anti-corrosion, anti-limescale and has a high load capacity.
It can also meet the needs of multiple household water sources and has a long service life.
What material is the liner of the popular Huangming solar water tank made of?
Recently, some consumers reported that the solar water tank leaked after only half a year of use. The important reason. because the covering is used for storage. If the hot water tank is made of poor quality material, the repair processdage is backwards and it has not undergone strict testing. It will corrode and leak water, rendering the entire water tank useless. I am very angry ! You can take a look at general corrosion and coating leaks. The main reasons are: the thickness of the coating is relatively thin, and it is made of low-quality stainless steel, which is easy to corrode and leak. The process is poor and welds are likely to appear, resulting in a short lifespan of the water tank, you can actually look at the inner tank of the water tank to identify it yourself. The thickness of the inner tank of Huangming solar water tank is more than 0.5mm. It uses high quality SUS304 high quality stainless steel inner tank. Professional cleaning tools are used before welding to avoid oil stains, which may result in solow udure. cracks, corrosion and water leakage, then computer test will be carried out to see if there is air leakage in the inner tank to prevent defective products from leaving the factory. If these materials and welding processes are qualified, the service life of the entire solar water tank liner will be extended. If you buy solar power, you can go to a physical store to study the solar water tank inner liner and learn about water tank material. I think you can also learn more about solar energy by logging into the official website. of Zhengzhou Huangming Solar Power!
Can Huangming nano solar coating still be used if it is broken?
Huangming solar coating uses SUS304 stainless steel coating and launches unique nano PP coating to areas where water quality is poore.
Huangming solar coating uses seamless and fully automatic argon arc welding, without welding points. Air drying indicates whether the insulation layer outside the water tank will be degraded.
Huangming insulation layer uses 40kg per cubic meter of foam, and after 40 minutes of curing treatment, there is no problem with air drying for 15 days
It cannot be used. Huangming is a solar energy brand. This product is equipped with a nano-liner, which is an important component of solar energy, if it is broken, it will affect the work of all solar energy, so it cannot be used. Huangming Solar Co., Ltd., as a global solar energy industry, promotes a collector area of 3 million square meters per year, which is equivalent to the entire European Union combined and more twice that of North America. and chino productshas an environmental label.
