The test in the condensed water-alternating climate in an atmosphere containing sulfur dioxide comes from the German industrial standard DIN 50018. This standard describes the conventional conditions of the condensate test chamber for the sample in the atmospheric environment containing sulfur dioxide. DIN EN ISO6988: The March 1997 version does not include the content of sulfur dioxide concentration, which is included, so as to achieve the feasibility of comparing the test results obtained in different laboratories, due to the sample under different systems It is impossible to eliminate the alternating effect, so it is very effective to test the same corrosion-resistant system in the same test device at the same time.
For different corrosion-resistant systems and different materials in the field, it is necessary to consider that the effects of sulfur dioxide on them are different. The shape of the sample, the preparation of the sample, and the duration of the test The siege of the ground, such as the judgment of the results, is not the object of this standard. The descriptions in this regard can be extracted from the corresponding standards or special regulations or unified one by one. The matters noted in the German Industrial Standard DIN 50905-1 to the German Industrial Standard DIN 50905-3.
The tests described in this standard performed by the condensate test chamber can be used to describe the performance of corrosion-resistant systems, and can also play a role in quickly identifying the problem. The comparison of the protection values ​​of different corrosion-resistant systems is only It is only possible to perform between sufficiently similar systems, provided that the corrosion strength of the test may significantly exceed the corrosion strength in the actual application environment, and the corrosion situation may extend to other mechanical devices.
Reel Wrapper is a machine designed for packing rolls of paper, film,non-woven and similar shapes manufactured in reels. It is ideal for reel axial wrapping across the cylinder diameter then along the longitudinal axis. The machine can be designed to radial wrapper or axial wrapper. This packing method can form a cocoon type packing. It is completely Moisture Water & Dust proof packing and protects the products.
