摘要:
A ceramic pressure measurement cell for use in a sensor for static and/or dynamic monitoring of the pressure of a liquid or flowable medium which includes a base body and a membrane connected to the base body such that one side of the membrane is in contact with the medium to be monitored. The pressure measurement cell has high chemical resistance and high temperature resistance for a plurality of chemicals which is achieved by applying at least one plastic film on the side of the membrane in contact with the medium.
摘要:
The invention relates to particulate solids comprising more than 90% by weight of natural or synthetic surface-active compounds for whicha) the mean particle size of the particulate solid particles is 10 to 3000 μm,b) the surface-active compounds are solid at room temperature, andc) the surface-active compounds have a melting point of from 25 to 250° C.
