Bacteria in water 9 exposed outdoors are effectively killed with ultraviolet (UV) light by suppressing post-treatment increase in the bacteria population due to photoreactivation. The apparatus shines UV light on the water 9 to kill bacteria and has UV light emitting diodes (LEDs) 1 that emit UVA light with a primary emission peak of 320 nm-400 nm. The antibacterial action of the UVA light emitted by the UV LEDs 1 prevents proliferation of bacteria in the disinfected water 9 due to photoreactivation.

The invention relates to a chitosan nano silver gelata used for treating an inflammation in a lower genital tract, cervicitis and cervical erosion of female and empyrosis, scalding, bedsore infection and other skin inflammations such as tinea manus and pedes, and various wound infections, etc. The medicinal raw materials of the chitosan nano silver gelata of the invention are the nano silver and chitosan polymer in respective therapy dose; the nano silver is the nano silver powder or the nano silver colloid; the chitosan polymer is the chitosan and the chitin and one or more than one derivative of the chitosan and the chitin. The product of the invention has the advantages of high efficiency and being nonpoisonous, and has an extremely strong antibacterial action and an excellent therapeutic effect; compared with other nano silver gelata, the chitosan nano silver gelata of the invention has the advantages of perfect sterilizing effect, long-lasting effect and tissue repair function.

The invention discloses a water-based antimicrobial moldproof hydrophilic paint for heat exchanger fin surface treatment. The paint comprises 3-30% of high molecular compound containing hydrophilic group, 0.05-1% of inorganic nano material with antibacterial action, 0.3-5% of curing agent, 0.02-0.2% of leveling agent and 2-10% of cosolvent. The inorganic nano material with antibacterial action is composed of 2-10% of nano oxide, 0.1-2% of silver salt or nano silver solution, 0.1-2% of reducer, 0.1-1% of stabilizer and the balance of water. Since the inorganic nano material with antibacterial action has high stability in the system, the antimicrobial and moldproof properties and hydrophilicity do not attenuate after the processing technique, and can last for a long time in the application process. The paint has the advantages of low addition amount and high cost performance, and does not influence the later working properties.

The invention relates to a metal ion modified collagen protein-polyvinyl alcohol composite fibre. On the basis containing collagen protein and polyvinyl alcohol it also contains metal ions capable of producing chelation crosslinking action. Said invention also relates the preparation method of said composite fibre, and said method includes the following steps: adding metal salt into the collagen protein-polyvinyl alcohol mixed solution to make chelation crosslinking modification to obtain spinning solution, and adopting a series of after processes so as to obtain the new type collagen protein-polyvinyl alcohol composite fibre.

This invention relates to a silver-bearing crustamine fabric with anti-biotic action and its preparing method, which is composed of 90.0-99.9 percent of crustamine powder in weight and 0.1-10 percent of insoluble silver compounds particles. The invention has great anti-biotic action, and can be used as medical dressing to restrict the bacteria on wound.
