What is a Corten Steel Flower Planter?
Yes, and it works very well. Here I introduce weathering steel in detail.
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion resistant elements, which has the characteristics of strength, plastic extension, molding, welding and cutting, abrasion, high temperature and fatigue resistance of high-quality steel. The weather resistance is 2 to 8 times that of ordinary carbon steel, and the coating property is 1.5 to 10 times that of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, corrosion resistance and life extension, thinning and consumption reduction, labor saving and energy saving. Weathering steel is mainly used in railway, vehicle, bridge, tower, photovoltaic, high-speed engineering and other long-term exposure to the atmosphere of the use of steel structures. Used in the manufacture of containers, railway vehicles, oil derricks, harbor buildings, oil platforms and chemical and petroleum equipment containing hydrogen sulfide corrosive medium containers and other structural parts.
Weather resistant steel Plant Pots surface treatment, can directly spray paint?
Weathering steel itself is resistant to weather, water, salt and acid rust after the natural formation of a protective layer, I am indoor and outdoor design and construction, we began to use more than 20 years ago, let him natural rust, can form a layer of crystals behind, do not paint, they naturally form a protective layer.
And because the corrosion resistance of the weather-resistant steel plate is very strong, in the natural environment and rain, the color of the surface of the intermediate material from the new steel plate to the formation of a stable and dense rust red protective layer experiences a violent and uneven change process from blue black to light yellow, to orange red, to rust red, and finally red and brown, which will become more and more beautiful.
Does weathering steel Flower Pots need to be sandblasted for rust removal?
It is obtained by mechanical method at high speed and projected on the surface of parts at a long distance, collectively referred to as shot blasting cleaning. It includes: shooting the projectile into the casting with sand, removing the mold sand and the core of the shot blasting sand; The projectile is thrown into the casting, forging, welding and heat treatment parts for surface cleaning to remove black skin, nodules, oxide film, rust spots, etc. The projectile is shot onto the surface of steel plate and various shaped materials for shot blasting pretreatment; The parts of spring, plate spring and gear subjected to variable stress are strengthened by shot blasting to eliminate stress and improve surface fatigue strength. For the decorative parts of household appliances or tableware, the surface of the shot polishing. However, from the perspective of process classification, shot blasting cleaning is limited to a cleaning process for the purpose of removing casting, forging, welding and heat treatment parts, and the shot blasting cleaning referred to in this lecture is this concept. For those who use the projectile to achieve the relevant process purpose on the workpiece surface, it is directly named after its process requirements, such as: shot blasting sand, shot blasting strengthening, shot blasting color enhancement, etc., in order to be different from shot blasting cleaning in the process.
When the part is cleaned, the facility that can make the part constantly change the surface in the ejection stream to achieve uniform shot blasting requirements is called shot blasting equipment, or shot blasting machinery. Due to the ever-changing cleaning parts, the shot blasting equipment of Qingdao Newsente Casting Machinery Co., Ltd. is also diverse. A certain specification of shot blasting equipment is only suitable for parts cleaning within a certain range. The special equipment is suitable for a certain part.
The principle of shot blasting cleaning is based on the high-speed projectile hitting the surface of the part, making the bullet indentation due to its local deformation. Each projectile indentation has three distinct layers of structure. Namely: brittle deformation layer on the surface of parts; The plastic deformation zone of the matrix in the middle layer of the part; Deep elastic deformation zone. These three effects produce the following three effects almost at the same time after the projectile strike: (1) to the plastic zone of the middle layer, the compression stress is generated instantaneously from five directions; (2) The cavity culture makes the middle layer compress and deform instantly in five directions, and pushes the surface layer instantaneously, so that the brittle layer with fracture line falls off quickly; ③ Almost at the same time, it also promotes the projectile to produce rebound force, so that it can obtain rebound speed and rebound out of the core. Three areas of projectile indentation occur and exist simultaneously.
