Under the premise of the designated test, weight measurement adhesives non-volatile matter percentage.
4, chemical resistance
Glued sample after the chemical action of an acid, alkali, salt and other ability to maintain its bonding function.
5, solvent resistance
Glued samples after maintaining its ability to act as a solvent bonding function.
6, water resistance
Glued samples after water or moisture action to maintain its ability to function glued.
7, ablation resistance
The ability to withstand high-temperature flame layer and high-speed air flushing.
8, permanence
Under the premise of use, gluing pieces of long-term ability to maintain its function.
9, weather resistance
Glued specimen ability to withstand the sun, cold, wind and rain, salt spray and other weather premise.
10, bonding strength
So that bonding adhesive sample and the adherend interface at or near the desired stress damage occurs.
11, wet strength
Under the premise of delineation, bonding after immersion in a liquid sample measured bonding strength.
12, dry strength
Under the premise of delineation, glued gum measured after the samples were dried bonding strength.
13, shear strength
In parallel to the layer of the load, glued destruction of the sample, the unit bonding surfaces are exposed to shear forces.
14, tensile shear strength
Tensile load acting in parallel to the bonding interface layer axially under the stress of the adhesive joint damage (Mpa).
15, tensile strength
In perpendicular to the layer of the load, glued destruction of the sample, the unit is exposed glued surface tensile strength (Mpa).
16, peel strength
Under the premise of the release delineated, so that bonding sample separation unit width can bear the load (kN / m).
17, impact strength
Glued specimens withstand shock loads and damage, the maximum power consumption of the unit gum junction (J).
18, bending strength
When glued or destruction of the sample reached delineated deflection under bending load is applied, the unit glue junction exposed to the maximum load (Mpa).
19, persistent strength
Under certain premise, within the designated time, in plastic junction can withstand the maximum static load. Expressed in MPa.
20, torsional shear strength
The maximum twisting moment under the cut, glued destruction of the sample, the unit can withstand glue junction to the shear force (Mpa).
21, compressive shear strength of dowel joint
Under the action of axial force, when the socket joint damage plastic junction unit can withstand pressure shear. Expressed in MPa.
22, fatigue life
In the designated load, frequency and other conditions, glued alternating stress or strain when the destruction of the sample number of rounds.
23, destructive test
By destroying the glued pieces to test their bonding quality tests.
24, non-destructive test
It is glued in quality without breaking the bonding member of the testing (such as X-ray analysis, ultrasonic testing, etc.).
25, boiling test
The glued specimens delineated by the time immersed in boiling water after measuring its bonding strength tests.
26, high-low temperature cycles test
So glued designated sample under high, low temperature alternating cycle, detect functional changes in the test.
27, weathering test
The glued specimens exposed to natural climatic conditions or simulated premise detect changes in functional tests.
28, accelerated ageing test
The sample is placed under the bonding is more demanding than the premise of natural conditions, changing its performance for a short time after the test test test.
29, fatigue test
Under the premise of designated frequency load, etc., measured by applying an alternating load fatigue limit strength or fatigue life of the specimens glued or crack
Test the entire process of fatigue fracture propagation rate or research.
