Wood conservation

I am working on a superstructure of wood pulp which has to be
replaced with appropriate wood. The strength, hardness, etc., should
correspond to the original. For that reason a treatment is
undertaken with acids, alkali, salts or other contents. As for the
acids we use: nitric acid, soft acid, sulfuric acid, milk and acetic
acid. Na2CO3, H2O2, bromine fluoride, chlorine and the organic are
as follows: phenol alkali, Na, NaOH, ammonia and others.

All these wooden pieces are neutralized and after they had been
neutralized they are built in the original. I would like to point
out that I don't know the real term for this kind of problem.
Somewhere it is described as corrosion of wood, artificial growing
old, dilapidation (degradation) of wood pulp. Does anyone know
anything about these problems.
