Abstract
Sposób wytwarzania tektury falistej charakteryzuje się tym, że co najmniej dwie warstwy płaskie papieru łączy się z co najmniej jedną warstwą pofalowanej tektury za pomocą roztworu skrobi, którego skład stanowi woda w ilości zawierającej się w przedziale od 74% do 76%, korzystnie 75,5%, skrobia pszeniczna w ilości zawierającej się w przedziale od 22% do 25%, korzystnie 23,8% wodorotlenek sodu w ilości nieprzekraczającej 1%, korzystnie 0,4% oraz czteroboran sodu w ilości nieprzekraczającej 1%, korzystnie 0,3%, gdzie w przeliczeniu na suchą masę roztwór skrobi nakłada się w ilości zawierającej się w przedzie od 6 g/m<sup>2</sup> do 10 g/m<sup>2</sup>, korzystnie 8 g/m<sup>2</sup>, przy czym roztworem skrobi powleka się dodatkowo całą wewnętrzną warstwę powierzchni papieru będącego w tekturze tzw. górnym papierem pokryciowym.The method of producing corrugated board is characterized in that at least two flat layers of paper are bonded to at least one layer of corrugated board by means of a starch solution, the composition of which is water in an amount ranging from 74% to 76%, preferably 75.5%. %, wheat starch in an amount ranging from 22% to 25%, preferably 23.8%, sodium hydroxide in an amount not exceeding 1%, preferably 0.4%, and sodium tetraborate in an amount not exceeding 1%, preferably 0.3%, where, on a dry weight basis, the starch solution is applied in an amount ranging from 6 g / m2 <sup> 2 </sup> to 10 g / m2 <sup> 2 </sup>, preferably 8 g / m2 <sup > 2 </sup>, whereby the starch solution is additionally coated on the entire inner layer of the surface of the paper in the cardboard, the so-called top cover paper.
