Electrolysis seals play an important role in the chemical industry and are used to seal liquids gases electrolysis cells. A good is critical performance reliability of process, ensuring that no unwanted substances enter system correct amount liquid gas flows through cell.This article explains most aspects geometries, materials for electrolytic required equipment.

This paper presents results of a systematic investigation to characterize the sealing of micromachined cavities using chemical vapor deposition (CVD) methods. We have designed and fabricated a large number and variety of surface-micromachined test structures with different etch-channel dimensions. Each cavity is then subjected to a number of sequential CVD deposition steps with incremental thic...

In industrial assembly lines, seam sealing is a painting process used for making watertight seals or for preventing rusting. In the process, sealant is painted on seams located at the joints of pressed metal parts. We developed a sealing robot system that adjusts the sealing gun motion adaptively to the seam position sensed by a range sensor (a scanning laser rangefinder which senses profile ra...

Gas transport mechanisms that characterize the hermetic behavior of MEMS packages are fundamentally different depending upon which sealing materials are used in the packages. In metallic seals, gas transport occurs through a few nanoscale leak channels (gas conduction) that are produced randomly during the solder reflow process, while gas transport in polymeric seals occurs through the bulk mat...

In order to reduce the failure probability of rubber sealing rings in reciprocating dynamic seal, a new structure of sealing ring based on bionics was designed. The biomimetic ring has three concave ridges and convex bulges on each side which are very similar to earthworms. Bulges were circularly designed and sealing performances of the biomimetic ring in both static seal and dynamic seal were ...

Bounded Apollonian circle packings (ACP’s) are constructed by repeatedly inscribing circles into the triangular interstices in a configuration of four mutually tangent circles, one of which is internally tangent to the other three. An integer ACP is one in which all of the circles have integer curvature. In this paper, we give a lower bound on κ(P,X), the number of integers less than X occurrin...
