Effect of different methods of treatment and preservative salts on salt distribution in treated transmission poles

Walchli, O.

Holz Roh- u. Werkstoff 22(2): 64-8

1964

Accession: 014435098
Compares preservative distribution as related to type of salt (Cu-As-Cr, acid UA, and CuSO4) and to method of treatment, viz. the osmose process, several sap-displacement methods (Boucherie, open-tank vacuum, open-tank vacuum/pressure, and boiler pressure/vacuum), and the alternating pressure process.
