1) Yon gwo kou obligatwa pou fè tès kawotchou. Depi kawotchou defòme anpil pandan etann, espesyalman pou pwodwi an latèks, elongasyon an ka osi wo ke 1000 pousan oswa plis. Se poutèt sa, anvan echantiyon an kawotchou kraze, li nesesè asire ke grip la nan machin nan tès kawoutchou tensile gen ase konjesyon serebral.
2) High-precision and high-frequency data acquisition Stretching rubber does not require a large force, and the tensile force measurement range does not need to be large, so the precision of the force value is required. It is generally required that the testing machine can obtain the force value with an accuracy of more than two decimal places. The accuracy of the rubber tensile testing machine of Suzhou Gopin is within ±0.5 percent . In addition, since testing the tensile properties of rubber requires several tensile force values during the tensile process, and the tensile test is not repeatable, the immediate and accurate recording of the tensile force value of each test section plays a very important role in the success or failure of the test.
3) Egzat mezi longè kalib ak aparèy anrejistreman Mezi a nan longè kalib echantiyon an se yon done enpòtan pou kalkile elongasyon kawotchou a, kidonk machin nan tès tensile dwe byen mezire souch echantiyon an nan tès la tensile kawotchou epi anrejistre li. imedyatman.
4) Aparèy ki ka dekri avèk presizyon -koub tansyon an Gen yon relasyon sere ant valè fòs rupture a ak longè kalib la nan echantiyon an rupture. Pou egzanp, estrès nan tansyon echantiyon an bezwen mezire lè echantiyon an lonje nan yon elongasyon bay. Valè fòs, pandan ke yon estrès bay mande pou mezire longè kalib kote echantiyon an lonje nan yon estrès bay yo. Apre tès la fini, koub egzat estrès -souch la ka repwodui pwosesis tès la, epi byen klè reflete valè chak seksyon tès la, ki bon pou kalkile atik tès la mande yo.
