The boron powder production is industrial metabolisms process. The resources and energy are transferred into products and discharges the waste. In this process, it inputs a variety of resources and energy and outputs products, various by-products and waste.
For different boron powder production process, the input and output are different. Meanwhile, their material metabolisms are varied. They have different impacts on the environment.
The concept of eco-efficiency was first proposed in 1992 at the world business council for sustainable development. Tools and theories to promote the development of enterprises towards sustainable direction is strongly advocated it as a; it as a relatively new environmental management approach is widely used. To implement eco efficiency, companies must provide competitively priced products and services to meet the needs of people's lives and improve people's quality of life, and gradually the entire product life cycle to the consumption of natural resources and the environment the impact is reduced to less than the Earth's carrying capacity.
Taking into account the actual situation of the boron powder production, mining can resource efficiency, energy efficiency and environmental efficiency of three indicators to measure the ecological efficiency of the titanium dioxide production. Boron powder production resource efficiency refers to the amount of product units of the natural resources that can be consumed in the production process of the boron powder, which is equal to the amount of product divided by the input amount of natural resources in the production process. The energy efficiency of boron powder production means the amount of product per unit of energy can be derived from the titanium dioxide production process, it is equivalent to the amount of product divided by the amount of energy inputs into the production process.
The environmental efficiency of the boron powder production unit waste emissions in the production process of the boron powder corresponding amount of product, which is equal to the amount of product divided by the production process on the amount of waste emissions to the environment, in the traditional sense, has been completed in a single enterprise The entire production process, according to the standard inspection or required to meet the user function, and has a certain value and is sold out items referred to as the product of qualified. An important point of view of industrial ecology is to negate the concept of waste, in its opinion that the so-called waste is a misplaced resource. In other words, the waste if a business or production processes to meet the downstream business or production processes use requirements, it still can be defined as the product supply of the downstream business or production process, product form for use as a raw material and production of other products.
A boron powder manufacturers in China is typical of the sulfuric acid process, through the perforation, blasting, shovel, transport processes of mining boron Ore; in the concentrator, boron Ore by crushing, magnetic separation and dehydration boron powder concentrate; boron flour mill, after the acid solution, washed, calcined, and the after-processing. The entire production process can be divided into power production, mining beneficiation. Road transport of titanium concentrate and sulfuric acid production. Boron powder in the production process, serious waste of resources, the environmental load caused by the more prominent. Boron powder production is almost entirely dependent on natural resources, there is no waste as the recycling of resources, resulting in lower resource efficiency and environmental efficiency of the plant.
Form the perspective of industrial ecology, production of the product is defined. Resource efficiency, energy efficiency and environmental efficiency of the production of boron powder are defined on the basis of the theory of eco-efficiency. The eco-efficiency calculations and analysis for typical metal powder supplier show that the sulfuric acid production process of boron powder has the highest energy efficiency. In the existing level of production technology, most of the output material is not utilized. They become the waste and are directly poured into the environment. It makes the low resource efficiency and environmental efficiency in the production of boron powder. Material exchange between boron powder factory and other manufacturers is one important way to reduce the environmental load in the production process.Source:http://www.mhcmp.com
The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
