What is "Salt spray test" ?


Many bathroom accessories seller and buyer hear the "Salt spray test" frequently. Yes, it is one of the very important standard to distinguish the quality of bathroom accessories. Usually, the quality bathroom accessories should through this test within 24 hours. However, even the bathroom accessories past this test, it doesn't mean they can be used in many years. Because your environmental conditions is very complicated sometime and everyone has his different use environment.

Ok, here are the some different languages for the concept of "Salt spray test" below:
This below part is from: http://en.wikipedia.org/wiki/Salt_spray_test
The salt spray test is a standardized test method used to check corrosion resistance of coated samples. Coatings provide corrosion resistance to metallic parts made ofsteelzamak or brass. Since coatings can provide a high corrosion resistance through the intended life of the part in use, it is necessary to check corrosion resistance by other means. Salt spray test is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its suitability in use as a protective finish. The appearance of corrosion products (oxides) is evaluated after a period of time. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period in testing without showing signs of corrosion.
Salt spray testing is popular because it is cheap, quick, well standardized and reasonably repeatable. There is, however, only a weak correlation between the duration in salt spray test and the expected life of a coating (especially on hot dip galvanized steel where drying cykles are important for durability), since corrosion is a very complicated process and can be influenced by many external factors. Nevertheless, salt spray test is widely used in the industrial sector for the evaluation of corrosion resistance of finished surfaces or parts.
Солевой туман — стандартизованный метод тестирования, используемый для определения коррозионной стойкости защитных покрытий. Покрытия защищают от коррозии изделия из стали,бронзы и других материалов. Поскольку покрытия являются достаточно стойкими к коррозии в обычных условиях, был разработан способ, позволяющий провести ускоренные испытания стойкости покрытия. Через определенное время выдержки образца в тумане проверяют, не появились ли продукты коррозии — оксиды. Продолжительность теста зависит от коррозионной стойкости покрытия; чем более стойкое к коррозии покрытие исследуется, тем большее время оно не должно показывать следов коррозии.
Тестирование солевым туманом популярно, поскольку оно дешево, быстро, хорошо стандартизовано и показывает достаточно повторяемые результаты. Однако корреляция между стойкостью в солевом тумане и ожидаемой жизнью покрытия довольно слаба, поскольку коррозия — достаточно сложный процесс, и на неё влияет множество других факторов. Тем не менее, тестирование солевым туманом широко применяется в промышленности для оценки коррозионной стойкости поверхностей и изделий с покрытиями.
Salzsprühtest (auch "Salzsprühnebelprüfung") ist eine standardisierte Prüfung für die Bewertung des Korrosionsschutzes verschiedener Überzüge. Es gibt verschiedene Normen, die ihre Vorgehensweise regulieren (ASTM B117, DIN EN ISO 9227). Die zu bewertenden Teile müssen in eine Prüfkammer gelegt werden, in der eine gesprühte Salzlösung(normalerweise eine Lösung von Natriumchlorid) die Teile korrodiert. Die Prüfung kann kontinuierlich durchgeführt werden; die Prüfungsdauer kann von 6 Stunden bis > 1000 Stunden erreichen. Überzüge mit hoher Korrosionsbeständigkeit ergeben eine längere Prüfungsdauer im Salzsprühtest.
Es gibt eine geringe Korrelation zwischen Salzsprühtest und der Korrosion bei normalen Bedingungen, da Korrosion ein sehr komplizierter Vorgang ist, aber der Salzsprühtest wird als Prüfungsmethode für die Qualitätskontrolle von Beschichtungen in allen Bereichen der Industrie benutzt.
L'essai au brouillard salin, aussi nommé test brouillard salin, est une évaluation standardisée de la résistance à la corrosionde matériaux métalliques, que ce soit avec ou sans revêtement, temporaire ou permanent, de protection contre la corrosion.
La conduite de ces essais est décrite par différentes normes (ASTM B1171,DIN 500212, EN ISO 9227 3. Dans tous les cas, les pièces à évaluer sont disposées dans une chambre d'essais dans laquelle une solution salée est vaporisée à une certaine température. L'essai peut être réalisé de façon continue de six à plus de mille heures. Les matériaux les plus résistants à la corrosion peuvent être soumis à des essais plus longs.
L'essai au brouillard salin donnera des résultats différents d'une corrosion dans des conditions normales. La corrosion est en effet un phénomène complexe. Cependant, l'essai au brouillard salin est une méthode de contrôle qualité des revêtements largement répandue dans l'industrie.
Therefore, before buying the bathroom accessories you can aks your supplier if their products have been passed the "Salt spray test". Wish you can get a general idea in this professional concept for this test.
Have a nice day!

The classification of bathroom accessories materials


Did you know the materials for making the bathroom accessories like Towel Ring, Paper holder, Towel Bar, Towel Shelf, Brush holder etc? Maybe you need some tips for choosing the comfortable bathroom fitting for your bathroom. Now let’s Easy Sanitary to show you!
There some kinds of material to make the bathroom accessories in the market. Like Stainless Steel, Alloy, Aluminium and Brass.


Here are some features for them below:

1) Stainless Steel Material: It is pretty good rust resistance. But it is difficult to be welded and working properties is not good as well. Therefore, it could be make the simple process working, the style of finished product is single and nothing new.

2) Zinc: Its working properties is not bad, so it is impossible to process by stamp. The base is very heavy because it is use the pour process only. The finished style is not fashion. As the fineness of surface is bad, the chrome working is effected seriously. The plating is easy to drop off.

3) Aluminium: The Surface could be make oxidation treatment or drawing and No chromed. Therefore, there is only the “Matte” style aluminium product in the market. But the most difficult problems you will face is “Cleaning”. The Aluminium is light and the Flexural Behavior is not pretty good as well.

4)Brass: It is the best material to make bathroom accessories as far. The Environmental brass is the most high quality material. Brass is rare and value and good for working properties. It has been used in many household products. H59,H62 are the good one. Because their 
adhesiveness is good with chrome plating, the fineness is pretty well once it is chromed. The chrome plating could be last more than 3 years because of strong adhesion. The prefect working properties help the engineer to design many fashion style.

The knowledges of RAW material for bathroom accessories are just for your reference. Everyone has his choice for him. If you need more details, we suggest you ask the seller to introduce.
