    Study Notes

    Preservative Retention

    • Determination of preservative retention in a specific zone of treated wood is done by retention by assay.

    Measuring Atmospheric Humidity

    • A psychrometer is used to measure the amount of water vapor in the atmosphere.

    Properties of Preservatives

    • Oil-borne preservatives leave the surface comparatively clean, paintable, and free from objectionable odor after treatment.

    Wood Drying

    • Kiln-dried wood is wood dried to a relatively constant temperature in a ventilated oven at 103°C.

    Wood Modification

    • Plasticizing is the process of softening wood by hot water, steam, or chemical treatment.

    Modified Wood

    • Modified wood is wood processed to impart properties quite different from those of the original wood by means of chemical treatment, compression, or treatment with or without heat.

    Wood Treatment

    • Niggerizing is a process of treating wood with paraffin or a coke-oven coal tar to increase its resistance to acids.
