Shaving veneer

A shaving veneer up to 1.5 mm thick is described, consisting of 80% to 95% by weight of dry wood shavings and 5% to 20% by weight of polyvinyl acetate glue. The method of producing shaving veneer is that wood shavings are mixed with a 33% aqueous solution of polyvinyl acetate glue, the mixture is pr...

Beschreibung
Zusammenfassung:	A shaving veneer up to 1.5 mm thick is described, consisting of 80% to 95% by weight of dry wood shavings and 5% to 20% by weight of polyvinyl acetate glue. The method of producing shaving veneer is that wood shavings are mixed with a 33% aqueous solution of polyvinyl acetate glue, the mixture is pressed at a temperature of 190°C and a pressure of 7 MPa, after releasing the steam it is pressed at a pressure of 25 MPa and then allowed to cool under pressure 13 MPa. Hoblinová dyha s hrúbkou do 1,5 mm pozostáva z 80 % až 95 % hmotnostných suchých drevených hoblín a 5 % až 20 % hmotnostných polyvinylacetátového lepidla. Spôsob výroby hoblinovej dyhy je taký, že drevené hobliny sa zmiešajú s 33 % vodným roztokom polyvinylacetátového lepidla, zmes sa lisuje pri teplote 190 °C a tlaku 7 MPa, po vypustení pary sa dolisuje pri tlaku 25 MPa a následne nechá vychladnúť pod tlakom 13 MPa.
