The PTI preservative imparts very little color to the wood. Producers generally add a color agent or a trace amount of copper solution so as to identify the wood as pressure treated and to better match the color of other pressure treated wood products. The PTI wood products are very well adapted for paint and stain applications with no bleed ...
*5 MPa is 5 ⋅ 10 6 Pascals or 5 ⋅ 10 6 Newtons per meter 2 or about fifty atmospheres pressure. *Solidity ≡ the ratio of the volume of solid to the bulk volume, or the ratio of bulk density to solid grain density d B /d G. Symbols: % v is percent by volume. Rock, mafic igneous: Air in Pores, 5 MPa Solidity = 1 0 % v OPA*: 1.50 5 % v OPA ...

It is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume. [ 1 ] Other moduli describe the material's response ( strain ) to other kinds of stress : the shear modulus describes the response to shear stress , and Young's modulus describes the response to normal (lengthwise stretching) stress.

Wood does not deteriorate simply because it gets wet. When wood breaks down, it is because an organism is eating it. Preservatives work by making the food source inedible to these organisms. Properly preservative-treated wood can have 5 to 10 times the service life of untreated wood. Preserved wood is used most often for railroad ties, utility ...
