D. 2 testing

2.1 General test conditions

The test is carried out at ambient temperature.

Before the test, cut off from the coil upper turns of the foil to a depth of at least 3 mm.

If the foil has a matte and glossy surface, the test is performed on a matte side of the foil. Test for wettability is carried out on the newly exposed surface of the foil. To re-open a new test surface. Do not carry out the re-test already on the surface of the tested sample. During the test, you must take precautions to avoid getting any liquid inside of the roll.

2.2 the Test by applying the liquid jet

Using a bottle spray to put on the controlled surface of the foil is tilted at an angle (40 to 60) degrees, a stream of distilled water or solutions of ethyl alcohol across the entire width of the roll. The surface of the foil along the entire width of the roll should be fully wetted with distilled water or aqueous ethanol.

2.3 Test by applying drops of fluid

With a dropper apply a drop of distilled water or solutions of ethyl alcohol by weight from 40 to 80 mg on a horizontal surface of the foil across the width of the coil at a distance of 5 to 10 cm from each other. Tilt the surface of the foil at an angle (40 to 60) degrees.

The rate of wetting is determined by the shape of a trace of motion of a droplet left on the surface of the foil (figure D. 1).

D. 3 test Results

The wettability of the surface of the foil corresponds to the class of wettability in which distilled water or solutions of ethyl alcohol not compressed (figure D. 1, a satisfactory wetting).

If there is a dispute in determining the wettability of the foil, use the solutions of ethanol in distilled water, prepared in increments of 5%.

These solutions are used in cases when you need a more rigid evaluation of wettability.

Annex E (mandatory). Definition of raskatyvaete foil

Annex E
(required)

This method establishes a test procedure for the determination of raskatyvaete foil.

The purpose of the test is to determine the extent of raskatyvaete fully annealed aluminum foil.

Ease of raskatyvaete is determined by the degree of slidenote between turns.

This test is used for aluminum foil with thickness from 0.006 to 0,050 mm.

E. 1 General test conditions

The test is carried out at ambient temperature. Prior to testing a cut off the top coils with a controlled roll of at least 3 mm.

Hang controlled roll high enough to foil can be easily unwound by hand.

E. 2 testing

Hang a roll of aluminum foil, which performs the test. Line raskatyvaete must lie in the same horizontal plane as the axis of the roll. Cut end of the foil must be located in a position corresponding to 12 hours on a clock face. Wind back the foil 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 foil. If the foil is spontaneously unwound to a position corresponding to 6 h, the coil is characterized by the degree of raskatyvaete A.

If the foil is spontaneously unwound, unwound free end of the foil one more complete revolution to a position corresponding to 3 or 9 hours on the clock face and release the foil. If in this case the foil is spontaneously unwound to a position corresponding to 6 h, the coil is characterized by the degree of raskatyvaete V.

In that case, if the foil is spontaneously unwound, unwound the free end of one coil and repeat the above procedure for matching the degree of raskatyvaete C. Acceptable degree of raskatyvaete think of degree A, b, C.

Appendix g (mandatory). Determination of adhesion of paint coating to the surface of the foil

App W
(required)

This method establishes the procedure for the qualitative evaluation of the breakout force of the printed image or varnish from the surface of the foil.

J. 1 Equipment, materials

Sticky tape should be to the force of exfoliation of not less than 90 g/cm width.

J. 2 testing

The foil pattern selected for testing, placed on a smooth hard surface. The tape is applied to the foil pattern across the width of the coil in the direction perpendicular to the direction of machining in the manufacture of seals, leaving a free portion of the tape to grip.

Smooth the tape tight with the click of your 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 foil or breakage of the tape. Visually inspect the tape.

The adhesion of the printing ink or varnish is estimated as follows:

And — not removed the varnish or paint;

In — on the sticky tape remains only a faint haze of glare, while not remained naked portions of the foil;

— Removes up to 10% of all paint or coatings, producing individual sections of clean foil;

D — deletes more than 10% of all paint or coatings exposing the clean foil.

And application (required). Rules for storage aluminum foil

The Application And
(required)

Aluminum foil is prone to corrosion and mechanical damage. Corrosion, in the vast majority of cases, arises under the influence of moisture, extreme temperatures and humidity and from exposure to different chemical compounds.

When careless handling of the rolls are easily clogged and the ends of the envelope surface are formed dents and nicks, preventing further free unwinding of the foil when using it. With the aim of preserving the consumer properties of aluminium foil required strict implementation of following rules.

I. 1 it is Prohibited to unload rolls of aluminum foil on the ground. In wet weather and winter time unloading the foil should be held in a special vestibule or under a canopy on a clean and dry loading dock, in the conditions, completely eliminates the ingress of moisture to the rolls of foil.

I. 2 it is Strictly forbidden to throw or turn over boxes with the finished products.

I. 3 In exceptional cases, when the forced delay boxes with foil in the open area, be sure to cover it with tarpaulin boxes to protect them from rain. The time of the forced storage at the open area should not exceed 5 days. Long-term storage of aluminum foil on the open areas is strictly prohibited.

I. 4 In the cold season, to avoid condensation of moisture on the surface of the rolls of foil (condensation or), it is prohibited to make and unpack the boxes with foil in a warm room.
