![]() ![]() The difference is that the aluminum rust inside the pressure cooker is layered, and the aluminum rust on the bottom of the pressure cooker is grain-shaped. Alkaline carbonate is formed, and the zinc on the surface of the waste dry battery often reacts with the ammonium chloride paste inside the battery to produce something with complex composition.ĭo you think aluminum will not rust if it is protected by a dense oxide film? A long-used aluminum pressure cooker has white aluminum rust on the inside and outside. Only in a low humidity environment will it be slow. In humid air, it will quickly form zinc hydroxide. For example, heated zinc will quickly react with oxygen to form zinc oxide. Zinc metal is more active, and there are many kinds of rust. Quickly fall off and continue to oxidize. When lead metal is exposed to oxygen, water vapor and carbon dioxide in the air, its surface will quickly oxidize to form lead alkali carbonates (lead has a variety of alkali carbonates), and the surface of this layer will be very exposed to water. The main component of patina is basic copper carbonate. When copper encounters carbon dioxide and oxygen in a humid environment, green patina will be produced. The most common rust phenomenon is that iron products have been exposed to the air for a long time and have an oxidation reaction with oxygen, or they are corroded by oxygen in the water to become oxides. If both are available at the same time, it is easy to rust. Iron rust is caused by the reaction with oxygen and water in humid air, and is related to oxygen and water. Under normal circumstances, the greater the energy consumed when a metal is refined, the faster the metal will corrode. This will significantly reduce the strength, plasticity, toughness and other mechanical properties of metal materials, destroy the geometric shape of metal components, deteriorate electrical and optical physical properties, and shorten the service life of the equipment. It is its thermodynamic instability, that is, the metal and itself are in a state of higher free energy than some compounds (such as oxides and hydroxides), so that elemental metal compounds will occur when the free energy conditions are available. Turn the metal into an oxidized (ion) state. Metal rust is a chemical reaction, also called metal corrosion, which refers to the process of destruction and deterioration caused by chemical or electrochemical reactions between the metal and its environment. Product Details What Is Rust And Why Do Metals Rust?

So, to recap, 1) CARROT's not going anywhere, 2) the Dark Sky API will be around for another 20 months, 3) more details to come on the transition, and 4) the redesign is coming along great and is going to blow you the fuck away. It's much too early to answer specific questions like "who will be the new default provider" - I need to negotiate with the different providers and figure out what makes the most sense in terms of functionality, accuracy for the largest number of users, and financials. Carrot Weather sources its weather data from the same data that Dark Sky used, so its local forecasts are often accurate and reliable. I use the Apple Weather App as of now, I wonder how accurate it is compared to The Weather Channel since that’s the source where Apple is displaying all the weather information on their. I've already personally spoken with the teams at a number of different weather providers and I am working to ensure that they'll fill any holes left by Dark Sky going away, such as the short-term rain forecast. How Accurate is Dark Sky Weather I was thinking of downloading this 4 app because it displays real time rain warnings/snow warnings and just general alerts. This very generous shutdown window gives me lots of time to plan for any upcoming changes. Carrot Weather Im looking into getting either of these apps, but cant choose between the two. The Dark Sky API will remain active until the end of 2021, so you don't have to worry about anything getting shut off any time soon. I invested a ton of time and energy into integrating a bunch of amazing weather data providers into the app (there are currently 8 total) - and all that work has helped to ensure that users will still have a lot of great options even if one is removed. It's still very early and I'm still processing the news, but I just wanted to answer the basic questions real quick.ĬARROT isn't going anywhere. So I think I’m going to keep mine for at least another year.I know a lot of you have questions about how Apple's acquisition of Dark Sky will affect CARROT. The Dark Sky API will remain available through the end of March, so services like Carrot Weather that use it for their weather data can continue using the data until then, then they will have to switch to Apple WeatherKit or find another provider. Listing those out I’m realizing there is still a ways to go for Apple.
