Film paper tensile testing machine is suitable for stretch film,
paper and other materials, peeling, tearing and other tests.
Film paper tensile testing machine film material is stretched, the
mechanical properties of the tear, puncture and other tests, and
low-cycle loading cycles, cycle deformation and displacement loop
function, strike elongation, tensile strength and other indicators.
Use a PC for data processing and analysis, test results can be
automatically saved, the test can be re-adjusted after the end of
the test curve, reproducible test procedure by traversing the
curve, or curve comparison, curve amplification.
Windows, visit the software test platform, with strong data
processing and graphics capabilities, instant print out the
complete test report and test curves.
Implementation of standards
GB / T 13022 Test method for tensile properties of plastic film
GB / T 16578 Determination of tear-resistant plastic film and sheet
ASTM DIN JIS BS, etc.
Film paper tensile testing machine can test items
(A) :( ordinary general test items displayed value and calculated
tensile stress Tensile strength
tensile strength elongation
modulus given stress elongation
given stress force value tear strength
force values at any point at any point elongation
adhesive strength and a peak value calculated values
Unplug the power puncture force test
(B) special test project:
1. The coefficient of elasticity that is Young's modulus of
elasticity Definition: The normal stress in phase component and
normal strain ratio. The coefficient of determination of a rigid
material, the higher the value, the more resilient material.
2. proportional limit: load and elongation within a certain range
to maintain the proportional relationship, which is the maximum
stress ratio limit.
3. Elastic limit: the material can withstand without permanent
deformation of the maximum stress was.
4. Elastic Deformation: After removing the load, the deformation of
the material completely disappeared.
5. permanent deformation: After removing the load, the material is
still residual deformation.
6. Yield point: the material tensile deformation faster but stress
is constant, this point is the yield point. Yield point is divided
into upper and lower yield point, generally above the yield point
as the yield point.
Yield (yield): more than proportional limit load and elongation no
longer proportional to the load would dump, then a period of time,
up and down, elongation changed greatly, this phenomenon is called
7. Yield strength: tensile, permanent elongation reached a
specified value of the load, divided by the original
cross-sectional area, resulting quotient parallel portion.
8. spring K Value: the ratio of the same phase distortion and
deformation of the components of the force.
9. Effective elastic and hysteresis losses: when the tensile
machine at a constant speed to stretch the sample to a certain
elongation or stretch to a predetermined load, when the measurement
sample contraction recovery work done and work expended the ratio
of the percentage is the effective elastic; measurement specimen
elongation, contraction ratio of the percentage of the loss of
energy of the power consumed and elongation, is hysteresis loss.
