1. What material is the towel rack made of
1. Space aluminum towel rack
The price of this material is relatively high, the material is stable, does not rust, and is environmentally friendly, but many of the space aluminum on the market are just aluminum alloys, and the quality of space aluminum in space equipment is greatly different, after all, only a small number of manufacturers can produce. So those comparison space aluminum towel racks need consumers to pay attention.
2. Copper towel rack
This towel rack is usually brass as the main material, the surface is chrome plated, showing a good mirror effect, giving a noble feeling. Copper high density, high strength, good stability, will not rust, more expensive, is a good towel rack material. However, if the copper is not chrome plated, there will be patina.
3. Stainless steel towel rack
The towel rack of this material is widely used, the surface is smooth, and it has a good look. At present, the best stainless steel material is 304 stainless steel, and 201 is slightly worse, after polishing or drawing treatment, it has a mirror effect. Stainless steel towel rack is hard, durable, not easy to rust, corrosion resistance, widely favored by consumers.
4. Zinc alloy towel rack
The towel rack of this material is diverse in color, style and style, and will not rust, but its weakness is that the material is brittle, easy to break, and rust spots can be long for a long time, it is not recommended to use the towel rack of this material.
Two, stainless steel and glass which is good
Stainless Steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel, resistant to air, steam, water and other weak corrosive media or stainless steel; The steel that is resistant to chemical corrosion media (acid, alkali, salt and other chemical etching) is called acid-resistant steel.
Due to the difference in the chemical composition of the two, their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid-resistant steel is generally stainless. The term “stainless steel” does not simply refer to one kind of stainless steel, but means more than one hundred kinds of industrial stainless steel, each stainless steel developed has good performance in its specific application field. The key to success is first to understand the purpose and then to determine the correct steel grade. There are usually only six types of steel related to the application field of building construction. They all contain 17-22% chromium, and the better grades also contain nickel. The addition of molybdenum can further improve the corrosion of the atmosphere, especially the corrosion resistance of the atmosphere containing chloride.
Glass is an amorphous inorganic nonmetallic material, which is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added.
Its main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with an irregular structure.
Widely used in buildings, used to isolate the wind and light, belongs to the mixture. Another mixed with some metal oxides or salts to show the color of colored glass, and through the physical or chemical method of toughened glass and so on. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called plexiglass.
It can be seen that there are many towel rack materials, each with its own characteristics, such as the space aluminum towel rack price is relatively high, the material is stable, does not rust, environmental protection, but many of the space aluminum on the market are just aluminum alloys, and the space aluminum in space equipment has a big difference.
