The boric acid – borate system can be useful as a primary buffer system (substituting for the bicarbonate system with pK a 1 = 6.0 and pK a 2 = 9.4 under typical salt-water pool conditions) in pools with salt-water chlorine generators that tend to show upward drift in pH from a working range of pH 7.5–8.2.
Zinc-borate compounds are less susceptible to leaching than sodium-borate compounds, but are still not recommended for below-ground use unless the timber is first sealed. [16] Recent interest in low toxicity timber for residential use, along with new regulations restricting some wood preservation agents, has resulted in a resurgence of the use ...
Borate ions occur, alone or with other anions, in many borate and borosilicate minerals such as borax, boracite, ulexite (boronatrocalcite) and colemanite. Borates also occur in seawater, where they make an important contribution to the absorption of low frequency sound in seawater. [1] Borates also occur in plants, including almost all fruits. [2]
Evidence of pest deterioration includes powder-like frass near entry and exit holes within the wood. Termites also feast on and live below the surface of the wood so they can be more difficult to detect. Termites discharge six-sided fecal pellets and, if found on a wooden object, could be used to determine the type of pest damage [8]
The bamboo must be treated to protect it against insects (namely beetles and termites). The most common and appropriate chemical to treat bamboo is boron, normally either a mixture of borax and boric acid, but it also comes in one compound (di-sodium tetraborate decahydrate). Both principles must be applied to a design in order to protect bamboo.
Disodium octaborate is a borate of sodium, a chemical compound of sodium, boron, and oxygen — a salt with elemental formula Na 2 B 8 O 13 or (Na +) 2 [B 8 O 13] 2−, also written as Na 2 O·4B 2 O 3. It is a colorless crystalline solid, soluble in water.
