Used green building materials to create a real safe & healthy environment.
Raw material used decides on the type of process and quality of solid wood engineered flooring. Hence, choice of raw materials should base on production and quality target, dimension, wood quality, structure, moisture content and other parameters of the raw materials would be checked to meet the requirement of floor board processingquality. Meanwhile, stringent control on temperature, deformation, pressure, accuracy etc are deployed to reduce the effect of processing errors on product quality.
The log is centered on a lathe and turned against a board cutting knife set into the log at a slight angle.
The slicing is made perpendictular to the annual growth rings of the tree. This creates a straight grain appearance
This is done from a board of fat sawn lumber rather than from a log. A variegated figure is created with this slice.
What is Heartwood?
Heartwood (or duramen) is wood that as a result of a naturally occurring chemical transformation has become more resistant to decay. Heartwood formation is a genetically programmed process that occurs spontaneously. Some uncertainty exists as to whether the wood dies during heartwood formation, as it can still chemically react to decay organisms, but only once.Heartwood is often visually distinct from the living sapwood, and can be distinguished in a cross-section where the boundary will tend to follow the growth rings. For example, it is sometimes much darker. However, other processes such as decay or insect invasion can also discolor wood, even in woody plants that do not form heartwood, which may lead to confusion.
What is Saptwood?
Sapwood (or alburnum) is the younger, outermost wood; in the growing tree it is living wood, and its principal functions are to conduct water from the roots to the leaves and to store up and give back according t o the season the reserves prepared in the leaves. All wood in a tree is first formed as sapwood. The more leaves a tree bears and the more vigorous its growth, the larger the volume of sapwood required. Hence trees making rapid growth in the open have thicker sapwood for their size than trees of the same species growing in dense forests. Sometimes trees (of species that do form heartwood) grown in the open may become of considerable size, 30 cm (12 in) or more in diameter, before any heartwood begins to form, example, in second-growth hickory, or open-grown pines.
