Audited Supplier Compound salt spray test chamber
The equipment has temperature, humidity and heat alternating salt fog compound testing machine that have the function of temperature and humidity regulation.Used for testing various performance indexes and quality management of accessories under alternating conditions of high temperature, humid heat, drying and salt spray.
The corrosion of metal materials mostly occurs in the atmosphere, which contains corrosive components and corrosive factors such as oxygen, humidity, temperature changes, pollutants, and so on. The corrosion of salt spray to metal salts is mainly caused by the electrochemical reaction of conductive salt solutions entering the metal, forming a micro-battery system of "low potential metal electrolyte solution - high potential impurities", electron transfer occurs, and the metal dissolves as an anode.
The main function of the compound salt spray corrosion process is chloride ions. It has a strong penetrating force, which easily penetrates the metal oxide layer into the metal and destroys the passivation state of the metal. At the same time, chloride has less hydration energy. It easily adsorbs on metal surfaces and replaces oxygen in the oxide layer that protects the metal from destroying the metal.
The programmable compound salt spray test chamber not only has the function of a basic compound salt spray test chamber but also combines the function of alternating cycle salt spray testing to provide test environments such as obsessive corrosion and filamentous corrosion. Test environments such as hot air drying, damp heat, and forced drying.
The compound salt spray test chamber is mainly used for auto parts, aviation equipment, photographic devices, building materials, electroformed coatings, electronic motor systems, and other metals under harsh environmental changes in electrochemical corrosion resistance.
Function of the compound salt spray test chamber
Although it is called the Salt Spray Test and the Salt Spray Test Chamber, the name is somewhat misleading. Sprays usually come in the form of fog or ultra-fine mist, creating an environment that accelerates corrosion. This situation can also be isolated by controlling the ambient temperature at 95°F (35°C) and PH.
Salt spray testing is used to determine the corrosion resistance of a material. These typically include the following:
Phosphating the surface followed by paint, primer, varnish, or anti-rust treatment
Galvanized and zinc alloys
Electroplated chrome, nickel, copper, and tin
Coatings that are not electrolyzed, such as zinc sheet coatings
Organic coatings
Paints and coatings
