摘要：It is a kind of detection cock valve seal by insertion cut from casting under sample slided to face. Even if passing through the sliding the sample under cutting from casting at middle part to balance thermal energy. During application viscose glue, apply in identical environment during all identical time frames of surface adhesive having the same being bonded (in addition to attached coupon tabs will be prevented from sticking chemically or mechanically in testing). The seal groove of elastomer preparation is identical prepared in a batch by with lower sample is cut from casting and other are equipped with the tackifier by same individual. The cross section of sealing element and test portion fuze seal test discount coupon. It is equally completed on sealing and sample after vulcanization. After the cooling period,When generation, the sample testing piece (carrying out preventing adherency chemically or mechanically relatively early) under cutting from casting is released and is placed into pulling-on piece fixing piece and a known load that vary applies. Monitoring extends an available stress/strain curves, carrys out experimental material performance. Further it is pulled out to failure, the bond properties of seal groove. Removal test label can test various other tests with
compression set and can be performed. Each be slidingly sealed can be generated in material and performance certification.
