Problems solved by technology

However, here is the problem that different types of plastic materials must be used for different applications, since properties such as flexibility and / or rigidity and working stress depend on the type of plastic material
However, this leads to time-consuming, expensive and extensive test series, ie for each desired application, which in turn leads to higher production costs

Embodiment Construction

[0148] The tested substances are listed in Table 1. Table 1 also includes a brief description of the composition of the raw materials and sample preparation. For samples W 02 , W 03 , W 04 , W 05 , Mo 02 , Mo 03 , Mo 04 and Mo 05 according to the invention, the pressing treatment was carried out in a molding machine at a pressing pressure of about 250 MPa. The sintering treatment of these samples was carried out in a tungsten tube furnace at a temperature of 850° C. in a pure hydrogen atmosphere for 60 minutes. Unalloyed tungsten (sample W 09) and unalloyed molybdenum (sample Mo 09) were uniformly compacted at 220 MPa, sintered at 2250°C for 4 hours and / or 2100°C for 4 hours, followed by roll bending Processing, the degree of deformation is about 70%.

[0149] The acrylic resin TransOptic from the company Bühler was used as polymer matrix for the preparation of polymer matrix composites, which is usually used for the preparation of polished parts. Molybdenum layers were dep...

Abstract

The invention relates to the use of an inorganic substance that forms hydrogen cations when entering in contact with an aqueous medium, said hydrogen cations triggering an antimicrobial effect. The inorganic substance contains molybdenum and / or tungsten.

Description

technical field [0001] The present invention relates to the use of a substance for achieving an antibacterial effect. Background technique [0002] Microorganisms such as bacteria and fungi are ubiquitous in our living spaces and thrive on most different types of surfaces. Many microorganisms are pathogens, and thus their spread and / or control play a special role in public health and hygiene. If such microbes get into our bodies, they can cause life-threatening infections. If someone gets the infection in a hospital, it's called a nosocomial infection. [0003] It is estimated that the world needs to spend tens of billions of euros every year to eliminate the losses caused by nosocomial infections. Therefore, the control of pathogenic microorganisms plays a special role in public health and hygiene. [0004] In addition to blocking and / or killing unwanted microorganisms through antibiotics, for example, preventive measures such as creating spaces inhospitable to microorg...
