Treatment of rubberwood (Hevea brasiliensis) (Willd.ex A.Juss.) Müll.Arg.with maleic anhydride to prevent moulds
wood modification mold prevention leaching wood moisture content
2016/8/2
The rubberwood samples were treated with 0.5–10% maleic anhydride (MA) solutions. The treatment of wood with 2.5% MA was adequate to prevent the growth of moulds on wood for 1 year at least. The viabl...
