This method establishes the procedure for the qualitative assessment of the strength of fixing of the printed image or paint layer on the surface of aluminum foil, plastic film and paper included in the composition of the material combined.

A. 1 Materials

Adhesive tape with a force of exfoliation from the surface of the layers constituting the material contain not less than 90 N/m.

A. 2 testing

A sample of the combined material selected for testing, placed on a smooth hard surface. The tape length (200±20) mm is applied to the sample print or paint the surface width of the roll in a direction perpendicular to the direction of machining in the manufacture of print (or paint coating), and at a distance of not more than 50 mm from the edge of the canvas material combined, leaving a free portion of the tape to grip.

Smooth the tape tight press of fingers. Quickly pull (not jerking) over the free end of the tape with constant speed at an angle of approximately 135°, but not to cause rupture of the material combined or broken belt. Visually inspect the tape.

The strength of the anchoring of the printed pattern or refinishing estimate the following degrees:

And — not removed the varnish or paint;

Line raskatyvaete of the test-coil should lie in the same horizontal plane as the axis of the roll. Stub end material combined must be located in a position corresponding to 12 hours on a clock face. Winding the combined material to a position corresponding to 3 or 9 hours on the dial (depending on which way spend the unwinding of the film roll) and let go of the material combined.

If the material is combined spontaneously unwound to a position corresponding to 6 h, the coil is characterized by the degree of raskatyvaete A.

If the material is combined spontaneously unwound, unwound the free end of the material combined for one full revolution to a position corresponding to 3 or 9 hours on the clock, and let him go. In this case, if the material is combined spontaneously unwound to a position corresponding to 6 h, the coil is characterized by the degree of raskatyvaete V.

In that case, if the material is combined spontaneously unwound, unwound the free end of one round and let him go.

In this case, if the material is combined spontaneously unwound to a position corresponding to 6 h, the coil is characterized by the degree of raskatyvaete S.

ANNEX b (mandatory). Method for determination of resistance to delamination between the foil and the plastic film between the plastic films in the material combined, including those made by way of maskirovanija and extrusion lamination


THE APP
(required)


The method consists in splitting the sample and measuring the force required to separate the layers of material combined from each other.

B. 1 Equipment, materials

Testing machine any Tina for:

— measurement of the load in the range test with the error not exceeding 3% of the measured load;

— the speed of the movable clamp (100±10) mm/min.

Device for cutting out samples with a width of (15,0±0,2) mm.

A pair of tweezers.

The ethyl acetate according to GOST 8981.

Band-aid or adhesive tape.

Roulette with a scale division of 1 mm according to GOST 7502.

Measuring with a scale division of 1 mm according to GOST 427.

B. 2 preparations for the testing

In order to efficiently approximate the technological control of the manufacturing process allowed the sampling of the combined material after its manufacture.

For the sampling sheet material combined with roll off at least three top coils and cut sheet across the entire width of the roll and a length not less than 700 mm.

On the selected sheet of material combined with a device for cutting samples cut three samples in the form of strips with a width of (15,0±0,2) mm and length (150±5) mm in the longitudinal and transverse directions at a distance of not less than 50 mm from edges for each pair of layers of material combined.

On the same sample allowed to measure the delamination force for only one pair of layers.

Samples having damaging the edges in the form of burrs, tears, trials are not allowed.

Sample for test is divided into sections:

1 — phase pre-delamination — (30±5) mm;

2 — outside area — not less than 50 mm;

3 — the working area — (50±5) mm;

4 — proslavery area — 15−20 mm.

Phase 1 pre-split manually. To facilitate the delamination of the end of the sample not more than 10 mm is immersed in a solvent that weakens the bond strength between the layers, while phase 2 should not be wet. If the sample cannot be stratified, the test is not carried out, and as a result of the test record: «the Material does not separate».

To prevent stretching of the elastic layer of the sample before the test, allowed him to reinforce on the outer surface of the elastic layer of the sample to stick a band-aid or any tape.

B. 3 testing

Initially set distance between the clamps of the tensile machine, is equal to (50±5) mm.

Sample fixed in the clamps of the tensile machine as follows: a fixed clamp layer with less elongation, of the movable layer with high elongation.

During the test, the sample is split until the end of the third area define at least five values of load on the readings of the recording instrument, read in the splitting of the working area. When delamination outside of the plot to observe the values of the load, as they can be unstable as the result of exposure of the sample in the solvent. The values of the load when the delamination outside of the site do not take into account.

In the process of testing proslavery recommend the site to support the tweezers so that the angle between the stratified and prosloennaya parts of the sample was 90°.

If the testing process is breakage of one of the layers of the sample, it is necessary to re-test for newly prepared samples. If repeated trials, again there is a cliff, record the load at which breakage of the sample. The sample shall be deemed satisfactory.

The delamination resistance of the combined material ГОСТ Р 52145-2003 Материалы комбинированные на основе алюминиевой фольги. Технические условия, N/m, is calculated by the formula

The average load value of delamination is determined by the results of six parallel measurements.

Test results of a combined material obtained by testing samples taken immediately after its production, are used to approximate process control. Final testing of such material is conducted upon expiration of the conditioning installed by the manufacturer.

Carefully glued to the surface of the foil tape with a length of at least 200 mm in the direction perpendicular to the incision, zakieva incision and leaving the free end to capture.

The free end of the tape slowly pulling at an angle of approximately 135° with a constant force. When this occurs, the delamination of the test material.

Such tests are made, sticking sticky tape on the edges and in the center of the sample in the longitudinal and transverse directions.

Visually inspect the tape.

G. 3 test Results

The resistance to delamination between the paper and the foil evaluate the following degrees:

A — excellent: all samples see 95% -100% bundle of the fibrous structure of paper or separation paper and foil does not occur;

In — satisfactory: the samples there is a significant destruction of the fibrous structure of the paper with the simultaneous detachment of the paper from the surface of the aluminum foil;

— Poor: destruction of the fibrous structure of paper is practically not observed, the primary separation of paper occurs from the surface of the aluminum foil.
