Even with gels and dressings, burns are still a therapeutic problem. Especially when the burn site is in the joint area of ​​the body, the curved skin is difficult to be bandaged. Researchers at Tokai University in Japan have developed an ultra-thin material that is close to the skin to handle those tough wounds and is effective against infectious bacteria.
The researchers said that the material is somewhat similar to cling film, has a flat surface does not require any adhesive, and can fit irregular surfaces, play a role in band-aid and gauze curl. This material is made of biodegradable polylactic acid. Researchers place the material in a test tube filled with water and perform centrifugation, which causes the material to break into smaller pieces. This is then repeated, and the liquid is poured onto a flat surface and the material is allowed to dry. These broken pieces will coalesce together to form a nano-film.
The team found that this nanofilm can fit on uneven surfaces and even fit tiny wrinkles. Later they discovered that this film could protect the burn wounds from infection, and it could prevent the entry of Pseudomonas aeruginosa, a pathogen that usually causes skin infections. The film can be used for three days, and researchers hope that this material can change the way burns are treated, which will help prevent infections and reduce the frequency of dressing changes. The experimental team is currently planning to test large animals.
Pulverized Coal Burner is an important part of asphalt mixing plant. Our company is engaged in the coal burner for more than ten years. With the use and continuous improvement of our customers, our pulverized coal burner is suitable for the quality of various kinds of coal. The coal powder stays in the high temperature zone of the pulverized coal burner for a long time, so the combustion efficiency is high, the flue gas is discharged directly without black smoke, and it is steam like white smoke.
The MPQ pulverized coal burner made by our company has been used all over the world, and its excellent performance has been widely recognized and praised.
MPQ series pulverized coal burner
Blackness 1. pulverized coal burner emissions as Ringelman 0-1;
2, equipped with special firebrick, prolong the service life.
3., the fixed carbon content of ash in the pulverized coal burner is about 0.1%, basically no carbon powder.
4. new energy saving rate of 1530% pulverized coal burner;
5., the flue gas content in the burner is changed to the lower flue under the condition of no flue dust removal. If the coal is fully burned, the national standard can be achieved.
6. the cost of fuel is low, accounting for only 1/5 of the cost of oil.
7., the air supply and fuel input of the burner can be changed according to requirements, and it can regulate furnace temperature and flame length in a wide range to meet actual needs.
8., the internal temperature field of the pulverized coal burner is uniform. The heated surface of the heated body is large, and the slag does not stick to the surface of the workpiece, and the product quality is good.
