Discussed is a welding rod inspection apparatus for measuring whether a welding rod is deformed and an inspection method using the same, and more particularly a welding rod inspection apparatus including a plurality of measures configured to be brought into contact with a predetermined position of a lower end of the welding rod and a support die configured to support the plurality of measurers. The plurality of measurers can be located so as to be spaced apart from each other by a predetermined distance, and each of the plurality of measurers or the support die can be provided with a pressure sensor configured to measure a pressure applied to the plurality of measurers. An inspection method using the plurality of measurers is also discussed.

The present invention relates to a polyvinyl chloride (PVC)-based compound composition, and more specifically, to a PVC-based compound composition that uses a PVC-based copolymer having internal plasticity prepared by suspension polymerization together with a PVC resin, thereby increasing compatibility with the PVC resin to shorten the gelling time, lowering the load at the time of extrusion to increase production in the same process conditions, and partially showing an impact modifier substitution effect.
