- curtain coaters are often used in the paper or B & P production to achieve a particularly high quality of coating with low use of the expensive coating color. Curtain applicators are therefore often used to produce the uppermost, the so-called cover layer. Since the top layer of the paper or B & P web is the layer which determines the appearance of the paper or board, the top layer is subject to particularly high quality requirements.
- curtain applicators but have the disadvantage that they are particularly sensitive to environmental influences. For example, air flow, fluctuations in temperature and / or humidity in curtain coating plants have a particularly negative effect on stable operation. Since applicators are generally located in close proximity to dryers such as cylinder dryers and / or infrared dryers, such coats are often operated in a high ambient temperature environment combined with high humidity. In order to degas the curtain coat of curtain applicators, ie, to ensure that the coating color can pass out of the applicator head of the curtain applicator without air bubbles, vacuum degassing devices are used which operate at lower temperatures Temperature must be operated to prevent boiling of the coating color.
