New Nano Films for Burn Treatment Prevent Bacterial Infection
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.
MORGAN series steel rolling guide is a kind of equipment used in the steel rolling process, it helps to guide and control the rolling direction and position of steel in the rolling mill. This equipment usually consists of a set of rolling guide wheels that can be adjusted as needed to ensure the correct position and orientation of the steel in the rolling mill.
MORGAN series rolled steel rolling guides have the following features and advantages:
1. High precision: The guide wheel adopts high-precision bearings and transmission devices to ensure the smooth and accurate movement of the guide wheel, thereby improving the rolling accuracy of steel.
2. Wear-resistant and durable: The surface of the guide wheel has been specially treated, which has good wear-resistant performance, and can be used for a long time without damage during high-speed rolling.
3. Flexible adjustment: The guide wheel can be adjusted according to different rolling requirements, including adjusting the position, angle and spacing of the guide wheel to suit steel products of different sizes and shapes.
4. High efficiency: The design and movement of the guide wheel can minimize the sliding and deflection of the steel, and improve the rolling efficiency and output.
5. Safe and reliable: The guide wheel is equipped with a safety protection device, which can prevent the steel from falling off the guide wheel or the guide wheel fails, ensuring the safety of operators and equipment.
In a word, MORGAN series steel rolling guide is a key equipment, which can effectively guide and control the rolling of steel in the rolling mill, improve rolling precision and efficiency, and ensure the quality and safety of steel.
