Veneer[edit]
- veneer is always glued on both sides of a sheet (to keep the sheet stable)
- veneer thickness is 0.6mm, so basic sheet thickness always increases with 1.2mm when veneer is glued
- when veneer on second size is not specified, ocoume is used
- before glueing veneer the sheet can be sanded in order to reduce thickness, a sheet with a basic thickness of 15mm is after sanding and gleuing veneer maximum 15.5mm thick
- source: Kuiper Plaatveredeling
Birch (BIR)[edit]
- density 600-700 kg/m3 - use 650 kg/m3 for calculations
- density with HPL (2x 0.75mm)
- 15mm 761 kg/m3
Ocoume (OCO)[edit]
- density 500-550 kg/m3 - use 525 kg/m3 for calculations
Poplar (POP)[edit]
- density 400-450 kg/m3 - use 425 kg/m3 for calculations
- thickness 4-9-15-18mm
- sheetsize 3050x1250
- density with HPL (2x 0.75mm)
- 4mm 818 kg/m3
- 9mm 631 kg/m3
- 15mm 556 kg/m3
- 18mm 536 kg/m3
ShipConstructor[edit]
For a correct weigth estimation of plywood with HPL, the density must be given per thickness, for a calculation method see 11016\our files\11016-70-900 interior.xls. Naming in database will be:
- 3 letter abbreviation - for bare plywood example bare ocoume: OCO
- 3 letter abbreviation / upper score / 2 digit thickness of bare sheet - plywood + HPL (HPL is always on both sides of panel) example sheeted birch plywood of 9mm thickness: BIR-09
