Borax is even used for historic landmark preservation, such as buildings and ships, for total wood protection.

Does borax damage wood?

Function. Borax kills termites and other rot-causing organisms. Borax is a desiccant that dries out water-damaged wood and helps seal and protect it from future rot. It is also a natural pesticide that kills termites, fungus and other wood floor enemies.

What is the function of borate in wood?

Borate compounds {i.e. borax, boric acid, Etidot 67 (disodium octaborate tetrahydrate) } convert to boric acid when they come in contact with wood whose pH is 4 – 5. In solution boric acid works as a weak Lewis acid which accepts an hydroxyl (OH -) to form a tetrahydroxyborate ion.

What is the best borate for wood chipping?

The laminate or particle board formed can be treated during the production process with various borates including zinc borate. Zinc borates are preferred in wood chip applications due to their ability to dissolve slowly and their compatibility with the resin systems used.

What is an amorphous boron rod?

Amorphous boron rod – Fused borate rods are typically composed of borates and used primarily for maintenance. A hole is drilled into the heartwood of a utility pole or other structure which would be suseptible to continual moisture. The rod is placed inside the drill hole and a plastic cap is placed to cover the hole.

Why are borate compounds not labeled?

That is why borate compounds are not labeled for use in the ground. The potential for constant availability of water will change the direction of the borate treatment in the soil around the structure. The reverse leaching process will slow considerably as the concentration of borate in the wood structure is reduced.

What is a boron azole?

Ammoniacal Copper Quinolate with boron (ACQ-B) and Copper Azole with boron (CBA)are compounds that have found wide use as an alternative to Chromated Copper Arsenate (CCA), has previously been used for the residential market.

How long do you dip logs in borate?

A number of log home manufacturers dip their logs in a solution of borate before they are shipped to the customer. Although there are set standards for the “Dip Diffusion” process, very few companies actually meet these standards, since it requires dipping green, unseasoned logs in a hot, concentrated borate solution and then storing the logs in a covered building for a minimum of two weeks. Most log suppliers simply dip their logs in a borate solution for a few minutes then allow them to dry. Although this procedure does not meet set standards, it has been used for over 20 years and as long as the borate concentration in the dipping solution is maintained at or above 10%, we rarely hear of this process not providing adequate protection to new logs.

What is pressure treated lumber?

Pressure treating wood with preservatives dates back to the 19th century when railroad ties were impregnated with creosote under pressure. Since then, a number of chemical formulations have been used for pressure-treating logs and dimensional lumber, but most have been discontinued due to their toxicity or health and environmental hazards. Due to their low mammalian toxicity and environmental friendliness, borates are now being used by a number of pressure-treating companies for treating both logs and dimensional lumber. The one limitation of borate pressure-treated lumber is that it cannot be used for wood in contact with the soil, since the moisture in the soil will extract out the water-soluble borate within a few years.

Borates are extremely effective at protecting wood from decay fungi (wood rot) by combining in solution with groups of biochemicals that are vital to metabolic processes at the cellular level. These combinations are then unable to take part in the metabolic pathway, and so the cells of the fungi starve.

Protection from flame

Boron compounds make effective flame retardants in lumber and plywood. Such compounds can be used in conjunction with other chemicals, including ammonium sulfate, diammonium phosphate or zinc chloride, or used alone.

Do beetles eat treated wood?

If not it will crystallize as the wood dries and remain as a barrier. As beetles emerge and eat the treated wood they will die.

Does borax kill PPB?

Go to www.borax.com for more info. Note that borax is not designed to kill PPB in sawn lumber. First, the PPB is not in green wood, so it would not be used to kill PPB, but rather to prevent them from getting into the lumber. If the lumber is air-dried, then the borax will leach out and not do much good.
