Bamboo treatment

Bamboo poles are treated to protect against insects attacking it especially bore. For this purpose we can use boric acid and borax (2:3 for 45 litres of water). Holes are made through to break the nodes using steel rod so that the chemicals will penetrate into the bamboo. After preparation of this liquid chemical, the bamboo poles must be submerged into it completely and should be kept in the same position for next 48 hours, during which, osmosis will take place and the entire sap content of the bamboo poles come out in the chemical solution and the chemical will diffuse into the bamboo poles until the concentration on both sides is equal. After this the bamboo poles are taken out from the chemical and it is kept outside to dry in shade for 7 days Minimum. During this, natural evaporation will occur leaving behind just the chemical content in the stem which will eventually crystallize.
