83.4gm Aletai iron meteorite slab SIZE:70*60*4mm KX685

Description: 【NAME】aletai iron meteorite KX685【WEIGHT】83.4gm【SIZE】:70*60*4mm【Receiving status】The surface of the slices you receive will be covered with a layer of 100% transparent wax, which can prevent rust. The wax is harmless. If you want, you can easily scrape it with a plastic sheet. Anti rust oil is not allowed to be used in air transportation. We specially use vacuum technology to cover the anti rust wax, so that you can keep it for a long time.[Vacuum wax sealing and rust prevention] In the vacuum state, the meteorite is immersed in the liquid anti rust wax, and the anti rust wax will penetrate into the tiny gaps on the surface of the meteorite, replacing the water and air in the gaps. Because of the high vacuum, the moisture in the micro gaps inside the meteorite is removed more thoroughly than the anti rust oil and coating, and the meteorite is completely wrapped to prevent rust. The wax film is harmless, soft, and can be rubbed off by hand, After rubbing off the antirust film, the antirust effect will not be affected. The most valuable thing is that the wax film does not affect the color of the pattern and the appearance. This rust prevention scheme requires the use of large vacuum heating equipment, which is high in energy consumption, expensive in materials, complex in operation, and time-consuming. However, according to the actual measurement, vacuum sealing wax is more effective than antirust oil and antirust coating, greatly prolonging the storage time of merchants and reducing maintenance costs. The disadvantage is that the surface is slightly greasy. The principle of both antirust coating and antirust oil is to isolate oxygen and water. The antirust coating cannot be operated under vacuum, and the antirust oil will evaporate after long-term storage. In addition, some antirust oil is dehydrated emulsified oil, which contains water itself. Therefore, some iron coated with oil will rust occasionally. Wax film is completely water free, even better.【Aletai Basic information】 Name: AletaiGeography:chinaObserved fall: NoYear found: 1898Mass: over 50tClassification:Meteoritical Bulletin: MB 105 (2016) Iron, IIIE-anCoordinates: (45° 52' 16"N, 90° 30' 17"E)【The current situation】NOW, MANY CHINA CITY CLOSED, SO WE DO NOT SUPPORT RETURN.【Payment term】Not to pay after seven days will automatically cancel the transaction【SHIPPING】We don't support combine shipping,Because the express company charged me the shipping according to the weight.
