Towel rack purchase knowledge
The scientific knowledge towel rack for the towel rack of sanitary ware products is used as a daily necessities. It is necessary to master some scientific knowledge before purchasing.
First, don't be misled by unscientific promotional methods.
For example, the current "space aluminum" phenomenon:
1. It is said to be the same as the "aluminum alloy" material in the aerospace equipment, the so-called "space aluminum". In fact, the current use of aluminum alloy materials in sanitary ware is very different from that used in aerospace equipment. The price alone is much different. The meaning of the sanitary ware is unaffordable. It is impossible to be this price at all. Besides, the "aluminum alloy" materials used in aerospace equipment are controlled. Those who manufacture aluminum alloy materials for sanitary ware rarely know "space aluminum" materials, and there is no "space aluminum". "This material grade.
2, the "space aluminum" is said to never rust, but also a promotional means of business, from the scientific knowledge, in fact, it should be said that common sense, material surface deterioration phenomenon is: aluminum -- - Oxidation, iron - rust, copper - copper, stone - weathered, wood - decay, plastic - aging, ------.
Second, the choice of material types
Ware products Towel racks are mainly made of stainless steel and copper. Nowadays, aluminum (is aluminum alloy), iron, zinc, plastic, etc. are used. Various materials are divided into many series. If necessary, you can find out in the “Practical Hardware Manualâ€. In contrast, the above-described stainless steel material strength is better.
Third, the stability of the material surface
1, depending on the nature of the material, 2, is the surface processing technology. The following describes the categories:
1. In contrast, the nature of stainless steel is not easy to rust (in fact, rust is an oxidation process). The characteristics ensure its stability, so it is also the most commonly used. "Stainless steel" only needs direct surface polishing or drawing. There is no change in the surface material, or additional coating, but depending on the grade, there are some differences in stability. The daily called 304 is better than 201. The surface is polished, the material is good, and the processing technology can reach the mirror surface, but it is worse than the copper plating.
2, "Copper" is basically made of brass, and the surface is chrome-plated, the treatment is good, can reach the mirror surface, plus the copper price, there will be a noble feeling, if not electroplating, the surface is very prone to patina, It can't be used. Such a plating layer is much more reliable than processing a layer of "paint" on the iron surface, but it also depends on the plating process. Otherwise, there will be a green patina when it is not used for a few years. Because the price of "stainless steel" materials commonly used in sanitary ware products is much lower than that of copper materials, some manufacturers do not absorb the characteristics of stainless steel and copper, and the stainless steel materials are electroplated and counterfeited as "copper" materials. However, although the cost of plating stainless steel is not cheap, it is generally cheaper.
3. Regarding “aluminumâ€, since the “pure aluminum†steel strength cannot meet the requirements of use and the surface is easily oxidized, it cannot be used. Generally, it is used in the rust-proof aluminum group or the hard aluminum group, but it is unlikely. It is made of the same aluminum alloy material as in the aerospace equipment. The surface of the "aluminum alloy" material subjected to surface oxygen oxidation treatment is much more stable than that without surface treatment. There are also various surface treatment results, mainly two. Species: One surface looks brighter, one is that the surface looks similar to matt, the former surface layer is thin but harder and not easily scratched. The latter kind of surface is like adding a coating layer. Although it is thick, it will be easy to scratch. The latter surface can be processed into a variety of colors. The aesthetic aspect is better, and it is also an advantage.
4, "iron", because it is easy to rust must be surface treated, divided into chrome plating or lacquering, compared to the "iron" above the plating layer without the "copper" above the plating layer to be reliable. With the lacquering process, the lacquer layer is also easily scratched and peeled off. However, it can be made in a variety of colors to make it look beautiful, and the paint layer has a good longevity, such as the automobile enamel paint layer, and there is no big problem for more than ten years.
5, "Plastic", in terms of steel strength, life expectancy is worse than the above metal materials, but engineering plastics in the automotive and other applications are also a lot of facts, so the reliability can basically meet the requirements of use, plastic It can be processed into a variety of colors, structures, and the cheapest features. I think it is a good choice for users who are temporarily used and not used for long-term use.
Material :Natural slate , quartz,sandstone ,marble etc .
Size :1-5mm,5-10mm ,4-8mm,8-12mm ,12-18mm etc .Can make the shape as your requirement
