Title: Method for evaluating deterioration of polyvinyl chloride resin
Inventor: YAMAZAKI TAKANORI
IPC: G01N17/00
Filed: 2002-06-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for evaluating deterioration of polyvinyl chloride for easily evaluating a state of deterioration without damaging the polyvinyl chloride resin.  <P>SOLUTION: Such a determination is made that the larger a measurement value indicating a hardness measured by a digital-display type hardness tester with the maximum spring load of not less than 29,000 mN is, the more highly the polyvinyl chloride resin is deteriorated. The hardness tester is used to measure the hardness of a sheet-like polyvinyl chloride resin while the resin is being tensioned, and a correlation line L1 between its tensile strength and hardness is obtained. The resin shows a higher hardness and a smaller elongation (%) as the degradation proceeds, as shown by a correlation line L2 between the hardness and elongation. The correlation line L2 has a very high correlational relationship with the correlation line L1. That is, the above specified hardness tester can measure a minute change of the hardness according to a change of tensile strength by gradually changing the strength so that an accurate measurement of states before and after the progress of deterioration can be measured.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-07-10
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a safe sample container with small capacity storing reacted sample when measuring chemical reacting conditions of a reaction system during manufacture of chemical products in a chemical plant.  <P>SOLUTION: A cap 32 is screwed to an opening of a container body 31 via a spacer 33, and a hole 35 connecting an outer surface of the spacer with the outside is formed on the cap 32. The spacer 33 is made of foil of stainless steel 361 with a thickness of 0.01 to 0.3 mm, and covers the opening of the container body 31 to seal up the container body for sealing up by screwing the cap 32. When pressure in the container body 31 is increased to a designated value, the spacer is broken with the pressure and operates as a safety valve. As axes of both through-holes 35 are offset each other at both sides, the pressure is relieved with a spouting passage of the pressure crooked. The spacer 33 made of inexpensive foil or the like is simply placed between the members, and it does not cause any increase in size by adding to the container. Positioning and pressed contact of the inlaid spacer 33 are secured in an inlaid structure between the cap 32 and the container body 31, and an airtight property of the spacer 33 is improved accordingly. A positioning function such as a locking device is preferable to the spacer 33.  <P>COPYRIGHT: (C)2004,JPO
