摘要:
The invention relates to an anticorrosive agent comprising zinc dust, and a second component, an organic binder and a VOC-free or VOC-compatible solvent. In order to allow the metal workpieces to be coated in a reliable and energy-saving manner at constant quality, the binder comprises silicon dioxide and alkali silicate in a molar ratio of at least 4:1. The invention also relates to a device for mixing and metering solid and liquid components of an anticorrosive agent. Said device comprises means for metering the quantities of the respective components of the anticorrosive agent, a solution tank and a mixing device. An application system for applying the anticorrosive agent to a workpiece comprises a solution tank, feeding means, at least one pressure reducer connected to the solution tank and at least one spraying device connected to the solution tank.
摘要:
The processes for obtaining a microbial oil comprising one or more polyunsaturated fatty acids (PUFAs) from one or more microbial cells comprise removing water from the cell fermentation broth or lysed cell composition before demulsification is conducted. Such a process has the benefits of reduced demulsification time and reduced salt use. Microbial oil comprising one or more PUFAs can be recovered from microbial cells by the process.
摘要:
According to the invention, it was found that culturing of cells of the taxon Labyrinthulomycetes in a high content of sulphate makes it possible to obtain a biomass having a high EPS content, which biomass can in addition be advantageously further processed into a feedstuff.

According to the invention, it was found that culturing of PUFA-producing cells in a content of sulphate makes it possible to obtain a biomass having high cell stability and thus PUFAs protected against oxidation in a sustained manner, which biomass can in addition be advantageously further processed into a feedstuff.
摘要:
It has been found according to the invention, that a biomass containing an oxidation-sensitive material of value may be dried under particularly mild conditions by a method in which the drying gas is passed over the biomass to be dried in cycle gas mode.
摘要:
A method for applying at least one anticorrosive, liquid, metal-particle-containing coating agent to a workpiece (2) with the steps application of a first layer of a coating agent to the workpiece (2) application of a second layer of a coating agent to the first layer. In order to suggest measures that permit a time-efficient application of a two-layer coating made of anticorrosive, liquid, metal-particle-containing coating agent, it is provided that the second layer is applied while the first layer still needs to dry.
摘要:
A pressure relief valve suitable for limiting fluid pressure in a common rail of a fuel injection system comprises a first housing part having a first through-bore with a first segment, a second segment and the valve seat defined therebetween. A second housing part is screw fastened with the first housing part and includes a second through-bore disposed coaxially to the first through-bore. An overall rod-shaped valve member is axially displaceable within the second segment. A spring biases the valve member towards the valve seat. A portion of the valve member opposite of the valve seat includes a shaft having a terminal end formed with a non-round cross-section configured such that a tool inserted through the second through-bore and engaging the non-round cross-section prevents the terminal end, and thus the valve member, from rotating relative to the first housing part when the first and second housing parts are screwed together.
