Milk is not only good for health, but also can prevent skin sensitivity and support environmental protection. According to Hong Kongâ€™s â€œWen Wei Poâ€ reported on the 17th, a young German designer Domaski developed a completely environmentally friendly textile material made of milk, such as silk and cotton yarn. Milk-based garments are scheduled to be produced on a large scale next year. Several companies have expressed interest in ordering and hope that new products will bring new changes to the apparel industry and open up new markets.
The 28-year-old designer Domaschi won the prize in the German Textile Research Association with a milk-based garment design. The president of the association, Janssen, said that garments currently rely heavily on natural resources such as petroleum by-products or water, and consume thousands of gallons to make a small amount of cotton cloth. â€œAll petroleum-based things are limited, and like cotton cloth requires a lot of land, water and Chemicals are even more limited, so future fiber and textile production patterns must change."
High cost of 170 yuan per kilogram
Domaschi said that the concept of milk-based clothing came from his stepfather who had cancer. He suffers from severe skin sensitization when he is undergoing treatment, and even suffers from ordinary clothes. This inspired her to develop all-natural and non-allergic fiber materials. She said that milk-based fibers had emerged as early as the 1930s, but most used an excess of acrylic acid, and she hoped to make completely organic fibers.
After two years of continuous experimentation, Domaskey's laboratory team reduced the milk to protein powder, which was then boiled and compressed into a fiber that can be woven into fibers. She admits that the cost of this fiber is higher than that of organic cotton yarn, and 20 euros (about 170 yuan) can only produce 1 kilogram. It is only hoped that the manufacturer can reduce the transportation cost and the overall price.
Automobile manufacturers are also interested
Domarsky currently only applies the product to its own brand production online. Some automakers see that there is a potential for the use of seats for Laughter products. There are also service companies interested in ordering sensitive materials to make beds for hotels and hospitals. Janssen said that the German textile industry needs to develop creative products in order to survive the fierce competition. Domasksky's research is expected to expand into different industries and create a wide range of new products.
Graphite is an elemental element of elemental carbon. Each carbon atom is surrounded by three other carbon atoms (arranged in a honeycomb-like hexagon) to covalently bond to form a covalent molecule.
Since each carbon atom emits an electron, the electrons are free to move, so the graphite belongs to the conductor. Graphite is one of the softest minerals, and its use includes the manufacture of pencils and lubricants. Carbon is a non-metallic element that is located in the second periodic IVA family of the periodic table.
The specific use of graphite
1, for refractory materials, including refractory bricks, crucible, continuous casting powder, casting core, mold detergent and high temperature materials.
Magnesium carbon brick refractory material is the mid-60s, developed by the United States; in the world of magnesium carbon brick has been widely used in steel, and has become a traditional use of graphite. Aluminum carbon brick aluminum carbon refractories are mainly used for continuous casting, flat billet from the pipeline of the protective cover, underwater nozzle and oil well blasting tube.
Made of graphite and refractory crucible and its related products, such as crucible, curved neck bottles, plugs and nozzles, etc., with high fire resistance, low thermal expansion, melting metal process, by metal infiltration and erosion But also stable, good thermal shock stability at high temperatures and excellent thermal conductivity, so the artifacts and its related products are widely used in direct melting metal process.
Graphite and other impurity materials can be used as carbonizers in the steelmaking industry. Carburizing uses a wide range of carbonaceous materials, including artificial graphite, petroleum coke, metallurgical coke and Natural Graphite. In the world of steel-making carbon-based graphite is still one of the main uses of earth-like graphite.
3, for the conductive material
Graphite in the electrical industry is widely used as electrodes, brushes, carbon rods, carbon tubes, mercury rectifier cathode, graphite gaskets, telephone parts, TV picture tube coating and so on. Among them, Graphite Electrode is the most widely used, in the smelting of various alloy steel, ferroalloy, the extensive use of graphite electrodes. The graphite used in the electrical industry is very demanding on grain size and grade.
4, for wear and lubrication materials
Graphite is often used as a lubricant in the machinery industry. Lubricants are often not used in high-speed, high-temperature, high-pressure conditions, and graphite wear-resistant materials can be 200 â„ƒ a 2000 â„ƒ temperature and at a high sliding speed (loom / s) without lubricating oil work. Many of the equipment that transport corrosive media, widely used graphite materials made of piston rings, seals and bearings, they run, do not need to add lubricants, graphite milk is also a lot of metal processing (wire drawing, pull tube) when the good lubricant.
5, for corrosion-resistant materials
Graphite has good chemical stability. After special processing of graphite, with corrosion resistance, good thermal conductivity, low permeability and other characteristics, and widely used in the production of heat exchangers, reaction tank, condensate, combustion tower, absorption tower, cooler, heater, filter Pumps and other equipment. These equipment for the petrochemical, hydrometallurgical, acid and alkali production, synthetic fiber, paper and other industrial sectors, can save a lot of metal materials.
6, for the atomic energy industry and the defense industry
Graphite has a good neutron deceleration performance, the earliest as a slowdown agent for atomic reactors, "uranium-graphite" reactor is currently used more of an atomic reactor. As the power of the atomic energy reactor in the slowdown material should have a high melting point, stable, corrosion-resistant properties, graphite can meet the above requirements.
7, for anti-scaling anti-rust materials.
Graphite can prevent boiler fouling. Tests have shown that adding a certain amount of Graphite Powder to the water prevents the surface of the boiler from scaling. In addition, graphite coated with metal chimneys, roofs, bridges, pipes can be anti-corrosion and rust.
8, graphite new use
1) Flexible graphite products. Flexible graphite, also known as Expanded Graphite, is the 1970s developed a new graphite products. 1971 US research success of flexible graphite sealing material, to solve the problem of atomic valve leakage, followed by Germany, Japan, France also began to develop production. In addition to this product has the characteristics of natural graphite, but also has a special flexibility and flexibility. Therefore, it is an ideal sealing material, widely used in petrochemical, atomic and other industrial fields, the international market demand growth year after year.
2) the production of semi-metallic friction materials. Since the 1970s, clutches and automatic liners have been widely used semi-metallic friction materials. Semi-metallic friction material is the graphite and metal powder, steel fiber, clay powder made of synthetic resin. These automatic lining can be used for high-speed equipment such as aircraft, trucks and off-road vehicles, and clutch pads.
