Anti-sapstain and Termite Performance of Soda ash - Borax Mixtures

In many hardwood timbers the sapwood is susceptible to attack by sapstain and several woods destroying insects. Boron preservative is relatively harmless to human being and to livestock. Wood preservatives based borax have beenformulated by adding soda ash. The wood specimens were treated in 5% (wlv)solution offive conditions borax-soda ash compound i.e: 1.0: 1.5; 1.5:1.0;1.0:1.0;2.0:1.0,and 1.0: 2.0 (wlw).Observation ofsoda ash-borax mixtures efficacy wasperformed after e-xposure to sap-stain,subterranean termite Coptotermes curvignathus Holmgren and dry wood termite Cryptotermes cynocephalus_Light with choose methods. In the results, lower anti-termite {ndicates of5% solution soda ash-boraxformulation (1. 0: 2. 0) net dry salt retention expressed in terms of boric acid equivalent 7. 23 kg/m 3and anti sap stain indicates very good class with 4 week protection times.
